Global Copy Action not Working [message #225303] Mon, 30 October 2006 13:13 Go to next message

Originally posted by: mike.aol.com

I have read all the threads in this newsgroup and I still can't get the
global copy action to be retargeted for my GEF editor. I have
successfully implemented an analogous action for paste in the same
places. Here's what I've done:

ActionBarAdvisor: create, register, and add ActionFactory.COPY to the
main menu:

copyAction = ActionFactory.COPY.create(window);
register(copyAction);
...
menu.add(copyAction);

Implement an action, CopyTopologyObjectsAction, that extends
SelectionAction, using the same id as the global action:
ActionFactory.COPY.getId(). My calculateEnabled() method checks for
appropriate selected objects, which I know works fine for the context
menu that I'm using for this action. I set the ID, etc., in its init()
method:
protected void init() {
super.init();
setId(ID);
setText("&Copy");
setLazyEnablementCalculation(false);
}

In my editor:
protected void createActions() {
super.createActions();
ActionRegistry registry = getActionRegistry();
IAction action;
...
action = new CopyTopologyObjectsAction((IWorkbenchPart)this);
registry.registerAction(action);
getSelectionActions().add(action.getId());

public void init(IEditorSite pageSite, IEditorInput input) throws
PartInitException {
super.init(pageSite, input);
ActionRegistry registry = getActionRegistry();
IActionBars bars = pageSite.getActionBars();
...
id = ActionFactory.COPY.getId();
bars.setGlobalActionHandler(id,
registry.getAction(CopyTopologyObjectsAction.ID)); //note: ID is "copy"

In my ContextMenuProvider:
public void buildContextMenu(IMenuManager manager) {
...
action = getActionRegistry().getAction(CopyTopologyObjectsAction.ID);

manager.appendToGroup(GEFActionConstants.GROUP_EDIT, action);

The Copy action appears in the main menu, but it is never enabled. Any
clues what I'm doing wrong or how I can better debug this?

Thanks,
Mike Gering

Hi,
That action do not heard from selection change.
in gef.ActionBarContributor class, you will find a method as follows:

protected void addRetargetAction(RetargetAction action) {
addAction(action);
retargetActions.add(action);

//please pay attention this line
getPage().addPartListener(action);


addGlobalActionKey(action.getId());
}

try to add it to your create actions method, or selectionchange method.

> bars.setGlobalActionHandler(id,
> registry.getAction(CopyTopologyObjectsAction.ID));

Regards,

Qinxian

Thanks, but I'm still missing something very basic.

In the above, "action" refers to the global "copy" action, right? If so,
how can I get a reference to it from my makeActions() method?

Mike

Hi,
No, Sooorry my english, I'm china.
>From your code, you do not use ActionBarContributor but directly handle
action in editorpart. it's no matter.
and there is a need that this action need updated, someone responsible
for notificate it.
now can only add one line from your code,
getPage().addPartlistner(action)
after your register copy action.

other code is just for demo the need notificating action update.
