public interface IFocusService
This service provides 2 variables, activeFocusControl (a Control) and activeFocusControlId (the ID registered with the service).
You can use this service to provide default cut/copy/paste/selectAll for specific text controls outside of the normal workbench part lifecycle, like a control contributed to the trim. For example:
<handler class="org.eclipse.ui.internal.handlers.WidgetMethodHandler:paste" commandId="org.eclipse.ui.edit.paste"> <activeWhen> <with variable="activeFocusControlId"> <equals value="org.eclipse.ui.tests.focusText"/> </with> </activeWhen> </handler>
This service can be acquired from your service locator:
IFocusService service = (IFocusService) getSite().getService(IFocusService.class);

A control must only be registered once, but different controls can be registered with the same ID. Expressions evaluated against the activeFocusControlId would then be true for all of the controls thus registered.
We will remove ourselves as a listener when the Control is disposed.
