I cannot undo in my gef editor with keyboard but I can delete
I create a keyHandler :
keyHandler = new KeyHandler();
keyHandler.put(KeyStroke.getPressed(SWT.DEL, 127, 0),
getActionRegistry().getAction(ActionFactory.DELETE.getId())) ;
keyHandler.put(KeyStroke.getPressed(26, SWT.CTRL),
getActionRegistry().getAction(ActionFactory.UNDO.getId()));
keyHandler.put(KeyStroke.getPressed(25, SWT.CTRL),
getActionRegistry().getAction(ActionFactory.REDO.getId()));
and I reference it in my configureGraphicalViewer method :
GraphicalViewerKeyHandler keyHandler=new
GraphicalViewerKeyHandler(getGraphicalViewer());
keyHandler.setParent(getCommonKeyHandler(getGraphicalViewer( )));
getGraphicalViewer().setKeyHandler(this.keyHandler);
It works fine with the delet command but doesn t seem to run with the
undo/redo
thx

I'm not sure if those are the correct keystrokes for undo. Have you put a
breakpoint in handleKeyPressed to see what the event actually is and if it
gets sent at all?
Undo/Redo are global actions with keybindings associated with the menu
entries. The menu entries might be intercepting the keystrokes (although
I've been told that this isn't the case if the action is disabled). Either
way, you'll want to register action handlers for those global actions since
that allows the user to use the menu as well. The same it true for delete.
KeyHandler is intended for stuff that doesn't appear in menus, although for
previous version of eclipse DELETE was not stolen by hte edit menu

I tried some changes :
I don t bind CTRL + Z and DEL key with the KeyHandler

protected void buildActions() {
IWorkbenchAction
undo=ActionFactory.UNDO.create(getPage().getWorkbenchWindow( ));
addRetargetAction((RetargetAction) undo);
IWorkbenchAction
redo=ActionFactory.REDO.create(getPage().getWorkbenchWindow( ));
addRetargetAction((RetargetAction) redo);
IWorkbenchAction
delete=ActionFactory.DELETE.create(getPage().getWorkbenchWin dow());
addRetargetAction((RetargetAction) delete);
}
The actionDefinitionId is correctly set, (the key binding is correctly
shown in my Edit Menu) but the accelerator CTRL + Z or Del doesnt work...
