Eclipse Platform
Release 3.5

org.eclipse.debug.ui.actions
Class RulerToggleBreakpointActionDelegate

java.lang.Object
  extended by 

org.eclipse.ui.actions.ActionDelegate
      extended by 

org.eclipse.ui.texteditor.AbstractRulerActionDelegate
          extended by 
org.eclipse.debug.ui.actions.RulerToggleBreakpointActionDelegate
All Implemented Interfaces:
EventListener, IMenuListener, MouseListener, org.eclipse.swt.internal.SWTEventListener, IActionDelegate, IActionDelegate2, IEditorActionDelegate

public class RulerToggleBreakpointActionDelegate
extends AbstractRulerActionDelegate
implements IActionDelegate2

Toggles a breakpoint when ruler is double-clicked. This action delegate can be contributed to an editor with the editorActions extension point. This action is as a factory that creates another action that performs the actual breakpoint toggling. The created action acts on the editor's IToggleBreakpointsTagret to toggle breakpoints.

Following is example plug-in XML used to contribute this action to an editor. Note that the label attribute of this action is not displayed in the editor. Instead, the label of the created action is displayed.

 <extension point="org.eclipse.ui.editorActions">
    <editorContribution
          targetID="example.editor"
          id="example.rulerActions">
       <action
             label="Not Used"
             class="org.eclipse.debug.ui.actions.RulerToggleBreakpointActionDelegate"
             style="push"
             actionID="RulerDoubleClick"
             id="example.doubleClickBreakpointAction"/>
    </editorContribution>
 </extension>
 

This action can also be contributed to a vertical ruler context menu via the popupMenus extension point, by referencing the ruler's context menu identifier in the targetID attribute.

 <extension point="org.eclipse.ui.popupMenus">
   <viewerContribution
     targetID="example.rulerContextMenuId"
     id="example.RulerPopupActions">
       <action
         label="Toggle Breakpoint"
         class="org.eclipse.debug.ui.actions.RulerToggleBreakpointActionDelegate"
         menubarPath="additions"
         id="example.rulerContextMenu.toggleBreakpointAction">
       </action>
   </viewerContribution>
