Re: [platform-ui-dev] Global menu enablement

[Randy Hudson <hudsonr@xxxxxxxxxx>]

This documentation does not mention
the need to call:
getSite().getActionBars().updateActionBars();
when changing the handler any other
time (outside of init(...)).  This is a common mistake for many developers
who are dynamically changing global action handlers and expect the retarget
action to get remapped to the new handler.

John has answered for the build actions. 

For Cut/Copy/Paste/Delete, these are regular workbench retargetable 
actions. 
You can hook a handling action using:
 
getViewSite().getActionBars().setGlobalActionHandler(ActionFactory.CUT.getId(),
cutAction);

If your view uses an inline text control, e.g. for in-place rename, you'll
need to delegate these operations accordingly.
There is a convenience class to help with this.  See 
org.eclipse.ui.actions.TextActionHandler.
See how this is done in the Navigator, in 
org.eclipse.ui.views.navigator.RefactorActionGroup.

For more details, see:

[platform-ui-dev] Global menu enablement












Hello,

      I'm having an issue that seems appropriate for the
platform-ui-dev
list, if I am seeking assistance from the wrong venue, please redirect
me.
Here's my problem.

I want to enable certain existing menu options on the Edit and Project
menus. We have developed a custom Navigator (part of the
Common/General-Purpose Navigator effort). I'd like to enable certain
actions (like "Build Project", "Clean Project", "Cut|Copy|Paste|Delete")
based on a user's selection in our Common Navigator. In the latter cases
I
also would like to substitute what actually happens to support these
operations for custom contributions to our navigator. Any suggestions?

That is, when a user selects a node in our Navigator (for instance, a
custom EMF representation of a ejb-jar.xml file), I'd like to enable
Cut|Copy|Paste|Delete in the Workbench Edit menu, and tie in the
appropriate actions.

When a user selects a project, (contributed by a custom Content Provider),
I'd like to update the selection and enablement of "Build Project"
and
other appropriate options under the Workbench Project menu.


Thanks in advance for your time and assistance.
