# GlideTimelineItem- Global

The GlideTimelineItem API extends the abstract ScheduleItem class to define additional properties that are specific to the time line.

A time line item is essentially any item that displays in a singular row across the time line. A GlideTimelineItem has zero or more associated spans \(TimelineSpan objects\).

**Parent Topic:**[Server API reference](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/server-api-reference/api-server.md)

## GlideTimelineItem - GlideTimelineItem\(String tableName\)

Create a "dummy" GlideTimelineItem object.

This is useful for creating rows that do not allow any YMoving into; however, contain nested children \(e.g. The top-level "Users" row in the Group Resource Timeline\). The **sys\_id**needs to be unique for DOM level functions to parse correctly. By default this object will not be "droppable" because a table name was not specified.

|Name|Type|Description|
|----|----|-----------|
|tableName|String|The name of the table associated with current object.|

|Type|Description|
|----|-----------|
|void| |

## GlideTimelineItem - GlideTimelineItem\(String tableName, String sys\_id\)

Constructor that sets the required table and **sys\_id**properties.

The rest of this object's properties should be set by the caller. By default, this object instance is "droppable" since a table name is specified.

|Name|Type|Description|
|----|----|-----------|
|tableName|String|The name of the table associated with current object.|
|sys\_id|String|The sys ID for the object.|

|Type|Description|
|----|-----------|
|void| |

## GlideTimelineItem - createTimelineSpan\(String tableName\)

Creates a new TimelineSpan object associated with the current instance object.

If no other TimelineSpan objects exist, the newly created object will share the same **sys\_id**as current instance object. Otherwise, a randomly generated GUID will be used.

|Name|Type|Description|
|----|----|-----------|
|tableName|String|The name of the table associated with current object.|

|Type|Description|
|----|-----------|
|Object|The newly-created span object instance.|

## GlideTimelineItem - createTimelineSpan\(String tableName, String sys\_id\)

Creates a new TimelineSpan object associated with the current instance object using the specified table and sys\_id.

|Name|Type|Description|
|----|----|-----------|
|tableName|String|Name of the table associated with current object|
|sys\_id|String|Sys\_id for the object.|

|Type|Description|
|----|-----------|
|Object|Newly-created span object instance.|

The following example shows how to use createTimelineSpan\(\) to create a new TimelineSpan object.

```
var project_id="741cc7491b6f1c5043de32231b4bcbc5"; // Project ID 
var grUser = new GlideRecord('user_resource');
grUser.addQuery('planned_task', project_id);
grUser.setQueryReferences(true);
grUser.orderBy('user.name', 'DESC');
grUser.query();
while (grUser.next()) {
  var item = new GlideTimelineItem(grUser.getTableName(), grUser.user);
  /* Specify the text to display in the left pane for this item. */
  item.setLeftLabelText(grUser.user.name); 
  /* Set the name of the image file (including it's path) */
  item.setImage('../images/icons/user.gifx'); 
  /* Specify whether or not to bold the text style of the item in the left pane. */
  item.setTextBold(true); 
  /* Set whether or not the current instance object can be clicked and dragged into another GlideTimelineItem */
  item.setIsDraggable(true);
  /* Create a new TimelineSpan object associated with the current instance object using the specified table and sys_id. */ 
  item.createTimelineSpan(grUser.getTableName(), grUser.getUniqueValue());
}
```

## GlideTimelineItem - getImage\( \)

Returns a string specifying the name of the image file associated with the current GlideTimelineItem.

|Name|Type|Description|
|----|----|-----------|
|none| | |

|Type|Description|
|----|-----------|
|String|The name of the image file associated with the current GlideTimelineItem. If no image is associated with the current item, an empty string \(""\) is returned.|

## GlideTimelineItem - getIsDroppable\( \)

Indicates whether or not the current instance object should be allowed as a "drop zone" when moving timeline elements vertically.

|Name|Type|Description|
|----|----|-----------|
|none| | |

|Type|Description|
|----|-----------|
|Boolean|True if droppable; false otherwise.|

## GlideTimelineItem - getLeftLabelText\( \)

Returns the text to be displayed in the left pane \(if enabled\).

|Name|Type|Description|
|----|----|-----------|
|none| | |

|Type|Description|
|----|-----------|
|String|The value of the text to be displayed in the left pane.|

## GlideTimelineItem - getParent\( \)

Returns the unique **sysId** of the current GlideTimelineItem's parent object.

|Name|Type|Description|
|----|----|-----------|
|none| | |

|Type|Description|
|----|-----------|
|String|The unique sysId of the current GlideTimelineItem's parent object. If the parent does not exist, this will return an empty string \(""\).|

## GlideTimelineItem - getTimelineSpans\( \)

|Name|Type|Description|
|----|----|-----------|
|none| | |

|Type|Description|
|----|-----------|

</table>The following example checks if an incident's state is "New" and sets the item text to bold.

```
var NewIncidentTimelineScriptInclude = Class.create();
NewIncidentTimelineScriptInclude.prototype = Object.extendsObject(AbstractTimelineSchedulePage, {

  getItems: function() {
    // Specify the page title 
    this.setPageTitle('New Incident Timeline');

    var groupNew = new GlideTimelineItem('new');
    groupNew.setLeftLabelText('New Incidents');

    groupNew.setImage('../images/icons/all.gifx');
    this.add(groupNew);

    // Get all the new incidents and add them to a new label 
    var grIncident = new GlideRecord('incident');
    grIncident.query();
    while (grIncident.next()) {
      // Loop through all and capture new incidents 
      if (grIncident.incident_state != '1') continue;

      // Create the item and the span item. 
      var item = new GlideTimelineItem(grIncident.getTableName(), grIncident.sys_id);
      var span = item.createTimelineSpan(grIncident.getTableName(), grIncident.sys_id);

      if (grIncident.incident_state == '1') { // New
        item.setParent(groupNew.getSysId());
        // Check and set bold text
          item.setTextBold(item.isTextBold() ? false : true);
        } 
      item.setImage('../images/icons/open.gifx');
      span.setTimeSpan(grIncident.getElement('opened_at').getGlideObject().getNumericValue(),
      grIncident.getElement('opened_at').getGlideObject().getNumericValue());

      // Show different colors based upon the priorities only for new incidents 
      switch (grIncident.getElement('priority').toString()) {
        case '1':
          span.setPointIconClass('red_circle');
          break;
        case '2':
          span.setPointIconClass('red_square');
          break;
        case '3':

          break;
        case '4':
          span.setPointIconClass('blue_square');
          break;
        case '5':
          span.setPointIconClass('sepia_circle');
          break;

          default: // Otherwise, the default point icon class will be used (Milestone)
      }

      // Common item properties 
      item.setLeftLabelText(grIncident.short_description);

      // Common span properties
      span.setSpanText(grIncident.short_description);
      span.setSpanColor('blue');
      span.setTooltip('<strong>' + GlideStringUtil.escapeHTML(grIncident.short_description) +
