IEditorActionDelegate,
IMenuListener,

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.

selectionChanged
public void selectionChanged(
IAction action,
ISelection selection)
-
Description copied from interface:
IActionDelegate
- Notifies this action delegate that the selection in the workbench has changed.
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.
