wxWidgets 3.1.0 Release Notes ============================= Welcome to the latest development release of wxWidgets, a free and open source cross-platform C++ framework for writing advanced GUI applications using native controls. wxWidgets allows you to write native-looking GUI applications for all the major desktop platforms and also helps with abstracting the differences in the non-GUI aspects between them. It is free for the use in both open source and commercial applications, comes with the full, easy to read and modify, source and extensive documentation and a collection of more than a hundred examples. You can learn more about wxWidgets at: * https://www.wxwidgets.org/ Documentation is available online at: * http://docs.wxwidgets.org/3.1.0/ wxWidgets sources and binaries for the selected platforms are available for download from: * https://github.com/wxWidgets/wxWidgets/releases/tag/v3.1.0/ Changes ------- Compared to the stable 3.0.x series, this version brings many improvements and even more bug fixes, please see the change log https://raw.githubusercontent.com/wxWidgets/wxWidgets/v3.0.2/docs/changes.txt for the incomplete list of the most important ones. Here is the maximally condensed summary: - New classes: wxActivityIndicator, wxAddRemoveCtrl, wxAppProgressIndicator, wxNativeWindow, wxPowerResourceBlocker. - And methods: wxDateTime::GetWeekBasedYear(), wxListBox::GetTopItem(), wxProcess::Activate(), wxTextEntry::ForceUpper(), several ones in wxRendererNative, wxStandardPaths::GetUserDir(), wxUIActionSimulator ::Select() and many others. Also new wxEVT_MAGNIFY event. - Significant improvements to: wxBusyInfo, wxNotificationMessage. - All around better support for high DPI monitors. - Much newer versions of bundled 3rd party libraries (notably libpng) and support for GStreamer 1.0 under Unix. - Revamped OpenGL support better suited to modern OpenGL (3.2+). - Further C++11 support improvements. - Support for latest compilers: MSVS 2015, g++ 5.3, clang 3.8. - A lot of bug fixes in wxGTK3 and wxOSX/Cocoa ports. - New experimental wxQt port. Platforms Supported ------------------- wxWidgets currently supports the following primary platforms: * Windows XP, Vista, 7, 8 and 10 (32/64 bits). * Most Unix variants using the GTK+ toolkit (version 2.6 or newer) * OS X (10.7 or newer) using Cocoa (32/64 bits) There is some support for the following platforms: * Most Unix variants with X11 * Most Unix variants with Motif/Lesstif * Most Unix variants with GTK+ 1.2 * Most Unix variants with Qt 5 or newer (experimental) Most popular C++ compilers are supported; see the install.txt file for each platform (following the links from docs/index.htm). Files ----- wxWidgets is distributed in source form in several archive formats. ZIP and 7z archives are for Microsoft Windows users and contain the files with DOS/Windows line endings while the compressed tar archives are for Unix systems (including OS X) and contain the files with Unix line endings. Please notice that some Windows tools still don't accept files with Unix line endings and that compiling sources with DOS line endings under Unix will fail, so please choose the correct file for your system. In addition to the sources, documentation in HTML, CHM and HTB (wxWidgets help viewer) formats is provided as well as an installer for Microsoft Windows. Notice that you will still need to compile wxWidgets even when using the installer. We also supply binaries of wxMSW libraries built with several versions of Microsoft Visual C++ and GNU g++ compiler for this release. Installation ------------ Unless you have downloaded the binaries for your compiler, you will need to build wxWidgets before you can test out the samples or write your own applications. For installation information, please see the install.txt file in the docs subdirectory appropriate for the platform you use. Licence ------- For licensing information, please see the files: * docs/preamble.txt * docs/licence.txt * docs/licendoc.txt * docs/gpl.txt * docs/lgpl.txt * docs/xserver.txt Although this may seem complex, it is there to allow authors of proprietary, commercial applications to use wxWidgets in addition to those writing GPL'ed applications. In summary, the licence is LGPL plus a clause allowing unrestricted distribution of application binaries. To answer a FAQ, you don't have to distribute any source if you wish to write commercial applications using wxWidgets. However, if you distribute wxGTK, wxQt or wxMotif (with Lesstif) version of your application, don't forget that it is linked against GTK+, Qt or Lesstif, which are covered by LGPL *without* exception notice and so is bound by its requirements. If you use TIFF image handler, please see src/tiff/COPYRIGHT for libtiff licence details. If you use JPEG image handler, documentation for your program should contain following sentence: "This software is based in part on the work of the Independent JPEG Group". See src/jpeg/README for details. If you use wxRegEx class on a system without native regular expressions support (i.e. MS Windows), see src/regex/COPYRIGHT file for Henry Spencer's regular expression library copyright. If you use wxXML classes or XRC, see src/expat/COPYING for licence details. Reporting Bugs -------------- The wxWidgets bug tracker can be found here: * http://trac.wxwidgets.org/newticket Please use the search function of our Trac installation to find any possibly relevant bugs before reporting new ones. Also please notice that often trying to correct the bug yourself is the quickest way to fix it. Even if you fail to do it, you may discover valuable information allowing us to fix it while doing it. We also give much higher priority to bug reports with patches fixing the problems so this ensures that your report will be addressed sooner.
