Hi,
I have an action - it should appear in the Toolbar for my views and
editors. For the views, the action should be enabled based on the
selection of a node in the treeViewer of the view. For the editors, the
action should be enabled if the active editor "is dirty".
I tried to implement the above Action using IWorkbenchWindowActionDelegate
since that provides a common set of actions for editors and views. But
then I cannot set the enablement condition there separately for the editor
and views..
Should I use ActionBarContributors for the purpose? If I do that, how can
I ensure that the action appears in the same position in the workbench
toolbar for the editor and view?
Thanks in advance,
Sree

Hi,
Managed to find a solution with a little tweaking around. Thought it might
be useful for somebody else who might get stuck similarly.
Used IWorkbenchWindowActionDelegate, and for the views, I set my
enablement condition in the Plugin.xml based on treeViewer's selected
object and its value. On the "selectionChanged" event, trapped the
editor's selection(where I was getting an AbstractGraphicalEditPart of the
GEFEditor). From the init() of the IWorkbenchWindowActionDelegate, I could
store the "workbench" handle too as class member. Then used the
"workbench" member to get the currently active editor inside the
"selectionChanged" event together with the ISelection(if it contained the
EditPart) to identify that our editor was selected. Enabled the action
button programatically by checking the isDirty of the currently active
editor, after the previously mentioned check..Now the same menubar and
toolbar actions support the enablement conditions from both our views and
editors!!
