Hi, everyone,
I'm trying to use GEF in my RCP program. I downloaded the RCP Shape
example from
http://www.eclipse.org/articles/Article-GEF-EMF/files/shapes rcp.zip and
found that the delete key doesn't work in this RCP program, while the
delete command in the context menu works fine. The delete key works in
the standard shapes plugin example too.
I tried to add the following code in configureGraphicalViewer() but it
still doesn't work.
KeyStroke delKey;
IAction delAction;
KeyHandler keyHandler = null;
try {
delKey = KeyStroke.getPressed(SWT.DEL, SWT.NONE);
delAction = getActionRegistry().getAction(ActionFactory.DELETE.getId());
keyHandler = new GraphicalViewerKeyHandler(viewer);
keyHandler.put(delKey, delAction);
viewer.setKeyHandler(keyHandler);
} catch (Exception e) {
e.printStackTrace();
}
I set a break point at WorkBenchKeyboard::executeCommand() and found
that command.isHandled() returns false, it seems that no handler is set
for the DEL key in the RCP program. Could anyone tell me how to handle
DEL key in a GEF/RCP program?
Thanks.
Hongtao
