Changed the trigger for in-place renaming of nodes in the tree of databases pane. The Properties dialog has been debugged and improved. ** Dec 09, 2008** ANNOUNCE.txt and setup.py have been updated. Fixed a bug in scripts/vitables. Fixed a small l10n problem. ** Dec 08, 2008** Fixed a small bug in insertion of nodes in the tree of databases pane. ** Dec 05, 2008** Fixed a subtle bug in the datasets access process. A small bug has been fixed. File Save As... operation has been debugged. Enhanced the render of datasets with just one row/column. Fixed a small bug in the synchronisation of the workspace with the tree of databases pane. ** Dec 04, 2008** A minor problem found in tables queries have been fixed. The content of just created filtered tables is now automatically displayed. Fixed a bug in the access to datasets with two or more dimensions. Nodes copying has been updated: leaves whose dataset is not readable are not copied Deletion of views tied to overwritten nodes has been implemented. The status bar is properly updated now when a node is renamed in the Tree of databases pane. ** Dec 03, 2008** The 'Recover last session' feature is fully implemented now. Fixed a small bug in the splash screen. Added a label in the status bar for displaying info about the node currently selected in the Tree of databases pane. ** Dec 02, 2008** Implemented the capability for zooming cell contents. Dynamic entries under the Windows menu are now checkable and exclusive. ** Nov 30, 2008** Fixed a bug in the navigation of huge datasets. Now displayed data is properly updated when a slider drag ends and when the table is wheeled. ** Nov 13, 2008 ** Navigation of huge datasets is now fully implemented. Every navigation device (vertical scrollbar, keyboard and mouse wheel) seems to work fine and to update displayed data when a buffer fault occurs. ** Nov 04, 2008 ** Navigability of huge datasets has been enhanced. The selected cell is now properly updated when a buffer fault occurs. It means that navigating the table with the keyboard works fine now. ** Oct 31, 2008 ** Huge datasets can be displayed and navigated. Several things remain to be done (usability enhancements) but the feature seems usable and stable. ** Oct 24, 2008 ** Opening files by dropping their icons in the databases tree panel is fully implemented. Some annoying problems that arised when nodes were moved around in the databases tree panel have been fixed. I've started to implement the support for huge datasets. ** Oct 23, 2008 ** Opening files by dropping their icons in the databases tree panel has been partially implemented. Fixed a couple of bugs in the Properties dialog: data types are correctly shown now. In-place renaming of nodes has been debugged. Fixed a little problem with groups expansion in the tree view pane that was rather annoying: now pasting a node (or creating a new group) expands the parent group if it was closed. So user can see that the node has really been added. ** Oct 22, 2008 ** More progresses in the datasets displaying: - the workspace and the tree of databases are synchronized now: if a leaf with a view is selected in the tree then the view becomes active in the workspace. And viceversa, if a view is activated in the workspace its leaf is automatically selected in the tree - when a node with views is overwritten (because a group has been created, a node has been renamed or a node has been pasted/dropped) the views are closed - the drag and drop behavior has been debugged ** Oct 21, 2008 ** Fixed a bug in the application quitting process: the temporary database wasn't properly deleted. ** Oct 20, 2008 ** The Windows menu has been reimplemented. ** Oct 19, 2008 ** Datasets can now be displayed in the workspace. Still importants things remain to be done, mainly to add support for quickly navigate huge datasets. ** Oct 17, 2008 ** The buffer.py module has been refactored and modified. ** Oct 16, 2008 ** Fixed a bug in the node rename and file save as operations. A node/file cannot overwrite itself. ** Oct 13, 2008 ** Fixed a subtle bug in the code for renaming nodes. Fixed a bug in the dialog for entering the name of a node when a group is being created or a node is being renamed: empty strings are not valid names now :-) ** Oct 11, 2008 ** The code for renaming nodes has been refactored. Affected modules are vtapp.py, utils.py, inputNodeName.py and renameDlg.py. The setup.py has been updated. ** Sep 26, 2008 ** Fixed some minor bugs regarding the enabled/disabled state of toolbar buttons and menu items. Added new module inputNodeName.py. It is used instead of renameDlg.py for creating groups and entering the initial name in renaming operations. ** Sep 25, 2008 ** The behavior of the Open Recent File submenu is now a little bit more user friendly. ** Sep 24, 2008** Fixed a bug in the file opening procedure. Files with no PyTables/HDF5 format are properly managed now. Some code in the vtapp.py module has been reorganized to make it more readable. ** Aug 02, 2008 ** Fixed a couple of bugs in the File menu: * the Close All action wasn't enabled/disabled properly * the Save As... action didn't work ** Jul 23, 2008 ** The porting of the nodeProperties subpackage has finished. ** Jul 21, 2008 ** Merged r1054 and r1055 from trunk. Every modified file has been merged but VERSION. ** Jul 18, 2008 ** The nodeProperties subpackage is being ported. At the moment the GUI part has been ported. Next step will be porting the code for attributes validation. ** Jul 15, 2008 ** Fixed a nasty bug that crashed the application every time a node was expanded in the tree viewer. The reported Qt4 error was: QObject: Do not delete object during its event handling! I've been unable to locate exactly where the bug was. Apparently it was produced by a strange interaction between VTApp and VTGUI classes so I've embedded VTGUI in VTApp and removed the vtgui.py module. It seems to fix the bug. ** Jul 07, 2008 ** The porting of the nodeProperties subpackage has started. A new module, nodeDoc.py, has been added. It is in charge of the information collection about a given PyTables node. This module makes unnecessary the following ones: nodeDoc.py, tableDoc.py, arrayDoc.py, unimplementedDoc.py and groupDoc.py. All those modules have been removed from the project. ** Jul 03, 2008 ** The behavior of the Preferences dialog has been tuned. ** Jul 01, 2008 ** The porting of the documentation browser has been done. The behavior of the documentation browser has been tuned. ** Jun 26, 2008 ** Added svn:keyword property to dbsTreeModel.py leafNode.py nodeItemDelegate.py groupNode.py dbsTreeView.py rootGroupNode.py ** Apr 18, 2008 ** Added contextual menus to the tree of databases view. Also a couple of menu items in the Help menu are working now. Functionality for configuring the application has been reimplemented. ** Apr 16, 2008 ** Added code for enable/disable actions depending on the selected node in the tree of databases view. ** Apr 15, 2008 ** Thre new icons have been added. Command 'Delete All Queries' has been reimplemented. The Query toolbar has been added. Tables queries have been reimplemented. ** Apr 11, 2008 ** A couple of methods have been refactored and now have a new signature. Calls to these methods have been updated. The dbDoc.py module has been refactored. The nodeItemDelegate.py module has been moved to the h5db subpackage. ** Apr 08, 2008 ** Added support for renaming nodes inplace. The code for node editing operations has been refactored. ** Apr 07, 2008 ** Implemented Node --> Rename command with overwriting support. ** Apr 03, 2008 ** Fixed a bug in the algorithm for recovering last session. Now if a given node doesn't exist then the application reports it and doesn't crash. Implemented Node --> New Group command with overwriting support. ** Apr 02, 2008 ** The overwriting feature has been implemented in the drag and drop of nodes. Splash screen readability improved. Fixed a bug in DBDoc.pasteNode method of dbDoc.py module. The overwriting feature has been implemented in the Node Paste... command. The overwriting feature has been implemented in the File Save as... command. Added code for setting the application icon. ** Mar 31, 2008 ** Processing command line fetaure has been ported. The last session recovering feature has been ported. ** Mar 28, 2008 ** Splash screen module has been debugged: now messages are drawn at the proper position. The following files have been updated: INSTALL.txt, README.txt, setup.py and Makefile. Version number has changed to 2.0. A note has been attached to the start of every source file of ViTables. In this note it is specified how the ViTables program is licensed. ** Mar 27, 2008 ** Copyright statement of source files has been updated. ViTables logo has changed: now it doesn't contain the Carabos logo. I've done this because now ViTables is not developed by Carabos Coop. V.. Instead it is a free software project maintained by myself. The ViTables source code license has changed. From now on it has a GPLv3 license. ** Mar 26, 2008 ** Creating a branche for porting ViTables to PyQt4. Fixed a little problem in the drag and drop support of the tree of databases model/view. The treeEditor subpackage has been removed. The functionality of the File menu has been implemented. Only overwritting files during a File --> Save as... operation remains unimplemented. Fixed a couple of bugs in the tree of databases model: - the close database operation didn't remove the node from the tree view. - when opening a database fails the returned value was no specified. The configuration module has been rewritten. The configuration module has been rewritten. Small changes introduced in several modules: the name of some attributes has changed and some imports have been slightly modified. Small changes introduced in several modules: the name of some attributes has changed and some imports have been slightly modified. ** Mar 20, 2008 ** The vtgui.py module has been refactored and some small problems have been fixed: the size of the toolbars icons, the WhatsThis action setup, and the setup of the menu with entries for the toolbars. The vtgui.py module porting is done. The result is a module much shorter and clearer thant it was before. ** Mar 19, 2008 ** The porting of the vtgui.py module has started. It has been greatly simplified. The drag and drop behavior of the tree of databases view has been debugged a little bit. PyQt4.QtXXX libraries are now imported as QtCore and QtGui instead of qtCore and qtGui. In addition a couple of modules have some minor changes. ** Mar 18, 2008 ** Copy, cut, paste and delete operations have been implemented in the tree of databases model. Overwriting has not been considered yet. ** Mar 05, 2008 ** Basic drag and drop of the tree of databases model/view works! Nodes can be moved from one location to another (even in a different file). Nodes that belong to files opened in read-only mode cannot be dragged. Lazy population of the model works fine too. ** Mar 03, 2008 ** The basic model/view implementation for the tree of opened databases is done. Databases can be opened and closed. The object tree of a given database is populated in a lazy way so that performance is guaranteed when opening files with a large number of nodes. Finally, icons are tied to nodes in the tree view. ** Feb 29, 2008 ** Drag and drop support is being implemented. ** Feb 27, 2008 ** Added basic support for renaming nodes in-place. ** Feb 26, 2008 ** Added support for custom context menus to the tree of databases view. Some modules have been changed in order to keep internal consistency. Minor modifications made in several modules. ** Feb 22, 2008 ** The h5db subpackage has been updated. Calls to Qt3 methods have been moved to Qt4 equivalent methods. nodes subpackage has been updated. Calls to Qt3 methods has been replaced by calls to Qt4 methods. ** Feb 20, 2008 ** createIcons function changed: removed a line that was commented out. The nodes subpackage migration has started. Calls to Qt functions/methods have been adapted to Qt4. ** Feb 18, 2008 ** The following modules have been ported: * scripts/vitables * vitables/utils.py * vitables/vtsplash.py * vitables/vtSite.py * vitables/vtgui.py This module has been split in two modules: logger class is defined in a new module now. * vitables/logger.py The whole preferences subpackage has been ported: * vitables/preferences/vtconfig.py * vitables/preferences/preferences.py * vitables/preferences/configException.py The following tests have been ported: * vitables/preferences/preferencesGUI.py * tests/preferences/test_vtconfig.py * tests/preferences/test_preferences.py ** Dec 16, 2007 ** The Spanish translation has been updated. WhatsThis help texts and some About... texts have been reformatted in order to improve the code readability. ** Dec 14, 2007 ** The previous bug fix in the editing of the TITLE system attribute was incomplete. It has been corrected now (hopefuly). ** Dec 13, 2007 ** Fixed a bug in the editing of the TITLE system attribute (accents raised errors). Some trivial enhancements have been done. The editing of user attributes has been improved. Overflow cases are now properly detected and a ValueError is raised. Although this is not the default behavior of numpy arrays (which are silently converted to the apropriate dtype when an overflow occurs) it seems more adequated for an end user application as ViTables. ** Nov 29, 2007** Drag and drop of nodes has been debugged. Cut and paste has been improved. I hope that editing nodes is now implemented in a quite robust way. ** Nov 28, 2007** The behaviour of the documentation browser has been improved. A couple of bugs have been fixed: - canceling the Open File... command works fine now - opening a new documentation browser doesn't give errors due to not found documents - trying to open a document that doesn't exist don't shows a blank page but a page with the message 'Document Not found' A mess due to the use of backslashes still happened on Windows platforms, specially in the list of recent files and in the navigation browser history and bookmarks. This problem has been hopefully solved. The copy and paste operation has been enhanced. Now a node can be copied and pasted in its parent group. The overwrite dialog is raised, giving you the chance to rename the pasted node. If you decide to overwrite, the operation fails (a PyTable exception is raised) because a node cannot be overwritten by itself. ** Nov 27, 2007** The template script that generates the Windows installer has been updated. Now it takes care of the available translations. Unittests have been updated. The search method for locating the application settings has been improved on Mac OS X platforms. ** Nov 26, 2007** Spanish translation added. A couple of minor problems have been fixed: - the .vitables directory is not created on Mac OS X platforms anymore - the message raised when a directory is dropped on the tree viewer is now clearer The User's Guide has been updated. ** Nov 23, 2007** Displaying of objects in tables widgets has been enhanced. Now cell contents are dynamically adapted to the available room. It means that how the content of a given cell is displayed depends on the column width. As a consequence, the displaying of multidimensional objects has been greatly improved. Some changes aimed to improve the i18n have been done. ** Nov 21, 2007** Fixed a bug in the creation of user attributes with dtype float32. Errors raised during user attributes editing are displayed in the attributes editing dialog, not in the logger. This make easier to user to realise that an error has been raised. ** Nov 19, 2007** The release version has been updated. The User's Guide source has been updated. The DocBrowser behavior has been enhanced. Opening a file for the very first time in the DocBrowser uses the home directory as a working directory. Before it used the installation directory which was ugly. ** Nov 02, 2007** Fixed a bug in the access to VLArrays elements. The bug avoided the creation of views for VLArrays. VERSION has been updated in vtSite.py. This is required in order to run properly on Mac OS X platforms because on these platforms the module is NOT overwritten by setup.py. The temporary database is not removed when quitting ViTables because on Windows platforms a Permission denied error is raised. **Oct 31, 2007** Explicit support for addressing 64 bit space has been added. Now ViTables can display tables with more than 2**32 rows with no problem. A small bug has been fixed (hopefully) in the node paste operation: pasting a node on an expanded group doesn't refresh the object tree i.e. the pasted node is not visible. The whole unittest directory has been updated/refactored/debugged. I forgot to update tests/test_all.py in the previous commit :-( Fixed a small bug in the File Save As... procedure. The file extension of the new file was generated in a wrong way because the full filepath was used to determine the extension. The right thing is to use the filename. **Oct 30, 2007** The Users' Guide has been updated. A specific icons has been given to the toobar button in charge of opening files so that users can appreciate that it can show a popup menu now. Fixed a bug in File --> Close All and Query --> Delete All. Closing a set of non selected nodes caused a wrong update of the QAction in charge of closing all open files. Deleting a set of non selected filtered tables caused a wrong update of the QAction in charge of deleting all filtered tables. Fixed a bug in the procedure used to close a database. A race condition has been removed. A new icon has been added. Fixed a bug in the updating of query QActions. The bug couldn't be appreciated by users because it happened when the application was about to exit. **Oct 26, 2007** The VERSION file has been updated. A new usability enhancement has been added. The Open button of the File toolbar is able now to open the file of Recent files too. **Oct 22, 2007** Fixed a bug in the initial setup of the application. Fixed a bug in the Properties dialog of empty groups. Creating and renaming node operations have been made more robust. Fixed a small problem of name qualification when accessing to a couple of PyQt attributes. **Oct 19, 2007** Usability of Properties dialog has been improved by fixing the visual behavior of attributes editing. The format given to catched errors has changed again. Now the readability of Syntax Errors is better. In the Filter Table dialog ValueErrors are explicitely catched now. **Oct 18, 2007** Some classes still were instantiated via apply(qt.QSomeWidget.__init__, (self,args)). Now qt.QSomeWidget.__init__(self, args) is used. The behavior of tables shown in the Properties dialog has been improved. Tables have been resized so that they occupy all the available horizontal space leaving no (anoying) gaps. **Oct 17, 2007** Fixed a small bug in the console that produced a wrong color update in some situations. Wild imports have been completely removed. The examples directory has been updated. **Oct 16, 2007** The management of application preferences and configuration has been improved. The code has been simplified and a small bug has been fixed. Fixed a bug in the Preferences dialog that made the Cancel button useless. Some error and warning messages have been changed in order to ensure that all of them have a consistent format. **Oct 15, 2007** The resize mode of the Tree Viewer widget has been fixed so that the widget's header resizes properly its sections when the widget is resized. A subtle bug has been fixed in the setup of the default configuration of the application. **Oct 11, 2007** Some logger messatges have been changed in order to make them self-explanatories. The installer template script has been modified. The name of the installer includes the kind of license now. Fixed a small bug in the File Save As... command. It avoided open files overwriting on Windows platforms. The format used for display catched exceptions has changed. Now it is more readable (although provides less information). **Oct 10, 2007** The format of docstrings has been updated. Now every docstring has a restructured text format. Docstrings of every module have been updated. In particular the updated sections are those that listed the names of classes, methods, functions and global variables contained in the modules. Code for moving a node from one location to a different one has been changed in order to improve the performance. **Oct 04, 2007** Fixed a bug in the paste node procedure. **Oct 03, 2007** The behavior of the Query results node of the tree view has been setup accordingly to its aim. A subtle bug has been fixed in the dbView.py module. When dealing with nodepaths os.path.join should be avoided in favour of tables.utils.joinPath. The reason: in Windows platforms os.path.join can produce paths with a mix of slashes and backslashes. A small bug in the template installer script has been fixed. The uninstaller didn't remove completely the ViTables entry from the Start menu. Fixed a bug in the opening file process. When the open file dialog was called for the first time (i.e. application startup) and the dialog was cancelled then later calls of this dialog were unusable. The procedure for saving a file with a different name has been slightly changed to avoid a nasty HDF5 error. The error was raised when the new file name was filename (with no extension) and a filename.h5 file already existed. **Oct 02, 2007** As no evaluation versions are going to be distributed the dbManager template is not needed now. That's why it has been renamed to dbManager.py Unneeded and obsolete files have been removed. A small bug has been fixed in vitables/nodes/leafView.py. The bug was raised by a bug in the underlying PyTables 2.0.1 The ViTables configuration has been updated. The Startup option `start in current directory` is now `start in home directory` to avoid opening unexpected directories in Windows and Mac OS X when ViTables is launched by double clicking its desktop icon. Fixed a small bug that prevented to start ViTables in the home directory (when configured to do it) in Windows platforms. The template script for generating installers has been modified to add more items to the Start menu: links to documentation (in both PDF and HTML4 formats) and to the examples directory. **Oct 01, 2007** The users' guide has been updated. A check has been added to several methods in vtapp.py, to ensure that filepaths do not contain backslashes because they produce a real mess in the Windows registry and the list of recent files. **Sep 30, 2007** Added a button for group creation to the Node toolbar. **Sep 29, 2007** Fixed a bug in the drag and drop of a node from a read-only file to a read-write one. **Sep 28, 2007** QActions updating and synchronizating panels strikes back! The last approache has been discarded because it didn't encompass every possible case. The new approache seems to work better and it is simpler. Fixed a bug that prevented empty nodes to be added to the object tree when the tree was expanded. Fixed a bug in the creation of new groups. Now the new group can overwrite any node with the same name placed in its parent group. Before only groups could be overwriten. **Sep 27, 2007** The Help Browser history and bookmarks are now stored in the configuration file instead of in their own files. Fixed a bug in the updating of the QActions state. **Sep 26, 2007** The list of recent files is now stored in the configuration file (or in the Windows registry) instead of in its own file. The last session is now stored in the configuration file (or in the Windows registry) instead of in its own file. unittests have been updated. **Sep 25, 2007** The configuration file lastdir, used to store the last opened directory has been removed. Now this information is stored in the application configuration file (or in the Windows registry). **Sep 24, 2007** Fixed a small bug in the recovering last session process. **Sep 23, 2007** Unittests have been updated. **Sep 22, 2007** Added a new usability improvement: the tree view pane and the workspace keep now their selection state synchronized. Several keyboard accelerators added. **Sep 21, 2007** A couple of small usability improvements has been added. The action Node-->New group has a keyboard accelerator now. **Sep 20, 2007** The dialog raised when a node editing leads to a naming problem is now more readable a.k.a useful. Added permission to create groups under the Query results root node. Fixed a bug that appeared when a node was moved from one file to a different one. Fixed a bug that appeared when a node was copied from one file and pasted into a different one. **Sep 18, 2007** A small bug has been fixed in the renameDlg.py module. Fixed a bug in the implementation of tables queries. The bug caused wrong values to be displayed in the query indices field (if requested) when the range of rows to be queried was other than (start=1, stop=n, step=1).. **Sep 17, 2007** A small bug has been fixed in the dbView.py module. The unittests under tests/h5db have been updated. **Sep 13, 2007** The dialog raised when a naming problem appears has been enhanced. Now, detailed information about the operation being executed is displayed and buttons text is self-explanatory. Fixed a small bug that affected the File Save as... operation. Added support for overwriting nodes when a new group is being created. Docstrings of dbMananger_template have been updated. Fixed a small bug in renameDlg.py. **Aug 09, 2007** Fixed a serious bug in node deletions procedure. **Aug 08, 2007** New, clearer descriptions are used in the Properties dialog, in help texts and in buttons text. Unneeded messages are not passed to the logger anymore. Management of filenames extensions has been improved. The Query menu has been simplified. The HelpBrowser toolbar layout has changed. It is clearer now. **Aug 03, 2007** All unittest modules have been refactored and debugged. __init__.py files have been added to the tests directory and its subdirectories. test_all.py module has been added so that all unittests can be executed easily. testingHOWTO.txt has been updated and moved to the tests directory. **Jul 31, 2007** Unittest module test_query.py has been added. The tables query implementation has been modified in order to make it more suitable for testing it with unittests. Fixed a bug that was hitting every module in the tests/nodes directory. Unittests in the tests/preferences directory have been updated. Unittest module root_package/test_commandLine.py updated. **Jul 25, 2007** Updated Mac packaging instructions to avoid linking sip/PyQt against wrong Python. **Jul 24, 2007** INSTALL.txt and ChangeLog.txt have been updated. VTApp.slotHelpAbout method changed. The info displayed in the About tab has been updated. Support for VLArrays has been enhanced. VLArrays with pseudo-atom of kind vlunicode are now supported. Module zoomCell.py has been updated accordingly to the recoded cell formatting methods of utils.py **Jul 23, 2007** Use a `make.sh` script instead of `make` to build Mac OS X DMG images. The process is not complete yet, since the license is not shown on opening the DMG image. That's why the `SLA.*` files are still in place. Makefile_windows and the template NSIS installer script have been updated. Now they take care of the LICENSE.html file. Makefile for unix has been simplified. Added RTF readme to DMG image with important details for Mac OS X. Removed the files for the Mac OS X DMG resource fork. The license file in the DMG root is enough and easier to place. ;) The Linux packaging system has been updated so that licenses are properly managed. **Jul 21, 2007** Fix the Mac OS X app not finding the `qt.so` extension in the appdir. Thanks to Doug Anderson from the PythonMac-SIG list for the solution. **July 19, 2007** Added a bunch of tests for testing that the actions of menu items if File, Node and Query menus are properly enabled/disabled depending on the kind and number of selected nodes in the tree viewer. **July 12, 2007** The way of saving settings in the windows registry has changed. Now settings are stored under the key Carabos/Vitables/Version/PythonXX. No changes have been introduced for Unix and Mac OS X platforms. The management of application settings has been improved. Some annoyances regarding the geometry of the main window and viewer panels have been fixed. **July 06, 2007** Module subprocess.py has been removed. Since no packages for Python 2.3 are built now the module is not required. Bug fixed in scripts/vitables. The order of the import sentences was wrong. **July 03, 2007** Screenshots for the User's Guide have been updated. Support for personal and site licenses has been added. **July 02, 2007** Makefile_windows slightly modified to ensure that del behaves like rm. hpViewport.py module has been changed in order to fix the speed problem hitting PyQt >=3.16. The PNG file vitables_wm.png has changed. It has been converted from RGB to indexed mode. This way transparency is properly handled in Windows boxes. **June 28, 2007** The 3rd_party_licenses directory has been removed. The MANIFEST.in, LICENSE.txt and utils.py files have been modified accordingly. The User's Guide includes now a copyright notice for Qt and PyQt. **June 27, 2007** Package Mac OS X app as a semi-standalone application (incomplete). The PNG used in ViTables windows as application icon has been updated. References to the evaluation version have been removed from ANNOUNCE.txt and README.txt. **June 25, 2007** The docBrowser subpackage has been refactored and debugged. The script used to generate the treeSymbols.png image has been updated. The icon for compressed arrays has been included in the script. The image treeSymbols.png itself has been updated too. The xml source of the User's Guide has been updated. **June 20, 2007** The mingwm10.dll library must be included in the installed ViTables because qt and pyqt have been compiled dinamically with the MinGW compiler. The Makefile mswindows/Makefile_windows and the template NSIS script mswindows/vitables.nsi.in have been modified to take care of this dependency. **June 15, 2007** Added a Confirm Uninstall page to the template NSIS script. Several changes intended to allow for generating user's guide in a Windows box have been introduced. **June 14, 2007** A small inconsistency in the ViTables behavior has been fixed: files are now open in read-write mode by default. The template NSIS script for the Windows installer has been updated and refactored. **June 13, 2007** A working version of the new Windows installer is ready. Refactoring will start in brief :-) **May 29, 2007** A new set of unittests has been added to the h5db subpackage. **May 27, 2007** Some minor changes introduced in the h5db subpackage. **May 26, 2007** Unittests for the h5db subpackage has been refactored and debugged. **May 24, 2007** Unittests for the h5db subpackage has been rewritten from scratch. **May 21, 2007** The Windows installer making process is being updated. Compilation is done with MinGW. **May 18, 2007** The Properties dialog for files has been slightly enhanced: the access mode is shown now in the database groupbox. A small bug has been fixed in the dataspace groupbox. The bug produced bad dataspace groupboxes when the number of children of the group was zero. Class NodeDoc and its descendants have a new, simpler signature. The preferences subpackage has been slightly refactored. Unittests are being updated. **May 17, 2007** The operations Node Rename and File Save as... have been enhanced and debugged. The dialogs involved in node renaming and file saving have been modified to make them more suitable for the new behavior of those operations. **May 15, 2007** The File Save as... operation has been refactored. We have got rid of the `h5file` attribute of root nodes in the tree view pane. It is not needed anymore due to the recent changes in the code. We have got rid of the parent widget argument in most of the application dialog ctors because this widget uses to be the application main widget, which is always accessible through the qt.qApp.mainWidget method. **May 14, 2007** The methods for iterating over tree views have been refactored. The mechanism for querying tables has been refactored and reorganized. Some modules have moved to different locations, some methods have moved to different modules, etc. The result is much more consistent than the previous implementation. Functionality provided by the xxxEditor modules of the treeEditor subpackage has been moved to other modules. The xxxEditor modules have been removed from the project. **May 12, 2007** Fixed an annoying bug that produced lots of error messages when a new database was created/open. It was caused by a bad interaction between VTApp.slotUpdateActions and DBManager.openDB methods. Several internal operations have been simplified. The code of the whole application is now clearer. **May 11, 2007** The utils.py module has changed. The function getNode has been moved to dbDoc.py module. Several modules are affected by this change. A bug has been fixed in the NodeDoc.move method. The bug caused that views of small tables werent properly displayed after a drag and drop operation. The way of accessing the DBDoc instance tied to a given item of the tree view item (i.e tied to a TreeNode instance) has been simplified. **May 10, 2007** Node editing reimplementation has finished. After a new refactorisation everything seems to work fine now. **May 09, 2007** Drag and drop of nodes has been reimplemented. Now it takes care of properly overwriting nodes and updating views. **May 08, 2007** Node editing refactoring is still on. Delete and paste operations have been reimplemented. **May 05, 2007** The mechanism for renaming and deleting nodes has been enhanced and debugged. A translate method has been added to some modules that (due to recent changes) need it now. The mechanism for cutting and copying nodes has been reimplemented. Now it is simpler and more stable. **May 04, 2007** The coupling between leavesManager.py and dbManager.py modules has been removed. Started a heavy refactorisation of the treeEditor subpackage. The group creation and renaming of tree view items in-place have been completely recoded. **May 02, 2007** Fixed a bug in node deletion: deleting a group with views didn't close the views. Module nameConflictDlg.py strongly refactored. **Apr 30, 2007** Drag and drop management is now simpler: we have got rid of the nodeDrag module information about drags is now encoded via QTextDrag method **Apr 27, 2007** Some methods of treeView module have been moved to the utils module. The vtInputBox module has a changed. Now it can be called more easily and used in a more consistent way. The implementation of the model-view-controller in the leaves manager has been fixed for renaming and dropping operations. Some minor changes have been done to descendants of NodeDoc class. **Apr 23, 2007** The queries management has been enhanced in several ways. On the one hand performance of the filling of the result table has been increased when a column for selected indices is required by user. On the other hand usability of the query dialog has been improved in some aspects. **Apr 20, 2007** Added a help system to the user's attributes page of the node properties dialog. Also the query dialog has been enhanced with a help system. The splash screen has been updated. Management of configuration exceptions has been simplified by reducing the number of classes to deal with. **Apr 19, 2007** The support for complex queries has been enhanced. Now columns whose names contain blanks can be queried too. **Apr 18, 2007** The preferences subpackage has been refactored and simplified. **Apr 15, 2007** Added support for complex queries. **Apr 14, 2007** A couple of bugs have been fixed: - the action Close view is inactive when the selected item is a group. However there was a LeavesManager.closeGroup method designed for closing every opened view under the selected group when the Close view action was launched. - the icons dictionary was recreated every time an icon was required by the application. It caused the openRecentFile action not to work at all. On the other hand the nodeProperties subpackage has been refactored and simplified. **Apr 11, 2007** The nodes subpackage has been refactored and simplified. **Apr 10, 2007** The h5db subpackage has been refactored and simplified. **Apr 09, 2007** The application exiting code has been refactored. Applied a workaround to a bug that hangs the application during the quit process: calls to methods Table.where and Table.whereAppend have been replaced by calls to Table.readWhere. **Apr 07, 2007** The queryDlg.py module has been heavily refactored. **Apr 06, 2007** The management of tables queries is still under revision. **Apr 03, 2007** The tables query syntax has changed in PyTables 2.0. Methods involved in querying tables have been updated. **Mar 31, 2007** The module resources.py has been renamed to utils.py. **Mar 30, 2007** Management of the application icons have been simplified. **Mar 29, 2007** The code for opening a node from the tree view has been refactored and simplified. Management of empty datasets has been improved. **Mar 28, 2007** Added support for CArrays. Until now CArrays were managed as regular Arrays: they shared the same icon and looked the same in Properties dialogs. Now an icon has been created for CArrays and they are explicitely identified in Properties dialogs. The attributes editing stuff have been refactored and simplified. **Mar 27, 2007** The editing code of the TITLE system attribute has been simplified. The directory vtBoxes has been renamed to vtWidgets. It is aimed to contain widgets specifically designed for ViTables and widely used for it. The following modules have been moved to this directory: - zoomCell.py - vtTableItem.py **Mar 26, 2007** The VTTableItem class has been refactored. The getNodeInfo method has been changed in classes derived from NodeDoc. As a consequence a more convenient way to access the info returned by this method is achieved. It means that the code that use the returned info is now simpler. Several modules are affected by this change. The copyright line at top section of every python module of the project has been updated. The General page of the Properties dialog has been slightly refactored. **Mar 24, 2007** Most of calls to vitables.resources.getAttr have been changed. The simpler form, object.attribute, is preferred unless the attribute name is stored in a variable. In this case only the first form can be used. A bunch of modules is affected by these changes. vitables.resources.getNode function rewritten. The methods for dinamically building the object tree (tree view) of a given database have been refactored and greatly simplified. zoomCell.py module refactored. The management of empty databases has been debugged. Fixed a bugg in the management of UnImplemented datasets. **Mar 23, 2007** In PyTables 2.0 some Table attributes have been renamed, other have disappeared and other have been added. In order to see if a Table has nested field the colnames attribute cannot be used anymore. One can use the colpathnames attribute for that purpose. zoomCell.py and buffer.py modules refactored. **Mar 22, 2007** zoomCell.py and buffer.py modules refactored. The methods for painting cells in a table widget have been updated and optimised. Debugged management of VLArrays with vlstring and object atoms. **Mar 21, 2007** The properties dialog of leaves has been updated. Several issues concerning with PyTables 2.0 have been fixed. Management of PyTables scalar arrays improved in the buffer.py module. **Mar 20, 2207** Fixed several minor issues in some help texts. ViTables dependencies on numarray package are being removed. The numarray functionality is now provided by numpy. As a consequence numarray will not be included anymore in the ViTables installer for Windows. Instead numpy will be included so the numarray license has been substituted by the numpy one in the 3rd_party_licenses directory. The examples directory has been updated. Most of the .h5 files are now PyTables 2.0 files. **Mar 19, 2007** ViTables dependencies on numarray package are being removed. Management of PyTables user and system attributes has been updated. At the moment only PyTables.2.0 attributes are supported. The names of the supported data types are still outdated. **Mar 17, 2006** Ensure that both PyTables format version 1.x and 2.x are supported in the case of VLArrays. zoomCell.py module has been heavily refactored and debugged. **Mar 16, 2007** Starts the adaptation to PyTables 2.0. buffer.py module refactored. **June 01, 2006** Solved a couple of bugs that were apparent only on Mac OS X. Several usability enhancements added: warning messages are highlighted in orange color, files with read-only access permissions are automatically opened in read-only mode, improved bookmarks management in the documentation browser... **May 23, 2006** New splash screen behavior. Now it provides the users with feedback that the application is loading. **May 19, 2006** Application geometry is now kept between sessions. It includes the position and size of the application window and the sizes of the components of the viewing area, i.e. the tree viewer, the workspace and the logger. **May 18, 2006** A new indicator has been added to the status bar. The indicator permanently shows the path of the item currently selected (if any) in the tree viewer. **May 16, 2006** A view for the selected leaf (if any) of the tree viewer can be opened/closed by pressing the plus/minus keys, in the very same way that group nodes can be expanded/collapsed. **May 15, 2006** Keyboard focus indicators have been added to the tree viewer and the logger in order to improve the application usablility, specially if you are moving around using the keyboard instead of the mouse. **April 28, 2006** Added in-place node renaming capabilities. Now a selected node of a given object tree can be renamed in-place as well as via Rename dialog. **April 27, 2006** Several contextual menus enhanced and debugged. **April 26, 2006** Added support for the cut node operation. **April 19, 2006** A PDF version of the User's Guide has been added. **April 07, 2006** Files opening has been made easier. Now, a file can be opened by dragging it into the tree viewer. **March 14, 2006** The query dialog has been improved. Now it remembers the last entered query and uses it to set the initial values of the query if it applies. **March 10, 2006** Added support for any file extension to the File Browser. When a table is queried, if the result table is empty, a suitable message is logged. **March 08, 2006** Implemented a mechanism to ensure that, if an error occurs when a dataset is being accessed, the application cursor will not remain frozen in its clock shape. The tables query dialog has been debugged. Empty strings are not valid names for the column of indices. **March 01, 2006** Node renaming has been debugged. User's Guide has been updated.
