Hi,

I am trying to connect my GEF editor with the RCP application wide
Undo/Redo support.

Do you have an idea how to do this or can you point me to a working example?

Kind regards,

Georg

I havent done anything with RCP specifically, but if you are referring
to the new IUndoableOperation stuff that appeared in eclipse 3.1, I
remember hearing that there were plans to migrate the GEF undo support
to that API.

Until that is done, I can say that integration is possible, but involves
some hacks when it comes to intercepting the operations built into the
graphical editor infrastructure (figure move, resize etc.)

regards,
Christian

Hi Christina,

I didn't get an answer but here is my solution. In my GraphicalEditor in
createPartControl I hooked into the global redo/undo actions like this:

@Override
public void createPartControl(Composite parent) {
super.createPartControl(parent);
IActionBars actionBars = getEditorSite().getActionBars();
actionBars.setGlobalActionHandler(ActionFactory.UNDO.getId() ,
new Action() {
@Override
public void run() {
if (getEditDomain().getCommandStack().canUndo()) {
getEditDomain().getCommandStack().undo();
}
}
});
actionBars.setGlobalActionHandler(ActionFactory.REDO.getId() ,
new Action() {
@Override
public void run() {
if (getEditDomain().getCommandStack().canRedo()) {
getEditDomain().getCommandStack().redo();
}
}
});
}

Kind regards,

Georg

Hi again,

update: the above solution is not correct (although it works in some cases).

I solved the problem by hooking into the global actions by creating an
action bar contributor (adding RetargetActions in the buildActions
method) like in the GEF shape example. See classes ShapesEditor and
ShapesEditorActionBarContributor there.

Kind regards,

Georg
