java.lang.Objectorg.eclipse.debug.ui.actions.RulerBreakpointTypesActionDelegate
public class RulerBreakpointTypesActionDelegate
Breakpoint ruler pop-up action that creates a sub-menu to select the currently
active breakpoint type. This action delegate can be contributed to an editor
with the editorActions
extension point. The breakpoint types are
calculated based on the toggle breakpoint target factories contributed through
the toggleBreakpointsTargetFactories
extension point.
Following is example plug-in XML used to contribute this action to an editor's
vertical ruler context menu. It uses 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.RulerBreakpointTypesActionDelegate" menubarPath="additions" id="example.rulerContextMenu.breakpointTypesAction"> </action> </viewerContribution>
Clients may refer to this class as an action delegate in plug-in XML. This class is not intended to be subclassed.

public void selectionChanged(IAction action, ISelection selection)
IActionDelegate
Implementers can use this opportunity to change the availability of the action or to modify other presentation properties.
When the selection changes, the action enablement state is updated based on the criteria specified in the plugin.xml file. Then the delegate is notified of the selection change regardless of whether the enablement criteria in the plugin.xml file is met.

IActionDelegate
This method is called by the proxy action when the action has been triggered. Implement this method to do the actual work.
Note: If the action delegate also implements
IActionDelegate2
, then this method is not invoked but
instead the runWithEvent(IAction, Event)
method is called.
