How to get the 'Delete' event in context menu of a selected item in package explorer? [message #486539]

Hi,

I have overridden "org.eclipse.ui.actions.ActionFactory.DELETE" action and provided more functionality at the time of 'Delete' in my application.

I have written following code to register my own Delete action like below.

private void registerXtpDeleteAction(IViewSite viewSite) {

IActionBars actionBars = viewSite.getActionBars();

if ( actionBars != null ) {

String deleteID = org.eclipse.ui.actions.ActionFactory.DELETE.getId();

orginialDeleteAction = actionBars.getGlobalActionHandler(deleteID);

if ( orginialDeleteAction != null ) {

actionBars.setGlobalActionHandler(deleteID,

new XtpDeleteAction(viewSite.getSelectionProvider()));

}

}

}

The problem is that, XtpDeleteAction only gets activated when I delete it by pressing "Delete" button from keyboard or from menu Edit->delete, but if I right click on a file in package explorer and select "Delete" then it doesn't call my overridden class.

What could be wrong here?

Thanks
Sudhir

Right. For historic reasons many views fill the the concrete actions
into their context menu and don't invoke the corresponding command.
Hence your trick doesn't work.

There's no workaround. The delete action is not supposed to be tweaked
but you could try the
org.eclipse.ltk.core.refactoring.deleteParticipants extension point.
