Hi,
I have a EditPolicy to capture the Mouse double click event, however
the returned request in the method getCommand(Request request) never match
the type REQ.OPEN, which is supposed to be double click event. the type of
request I got are only delete and createChild.
how can I capture the REQ.OPEN request through EditPolicy's request? or
there is another way to capture the mouse event upon a figure? thanks.

Hi Chen

You can simply handle the request in the performRequest() method in your =
EditPart:

public void performRequest(Request request) {
if (REQ_OPEN.equals(request.getType())) {
MessageDialog.openInformation(PlatformUI.getWorkbench()
.getActiveWorkbenchWindow().getShell(), "Double Click =
Worked", //$NON-NLS-1$
"Double Click on a node worked"); //$NON-NLS-1$
}
super.performRequest(request);
}

Cheers...
Anthony
