Hello RCP programmers,
is it possible in a multiple perspective app to constrain the
visibility of selected views on selected perspectives?
In my RCP app I have two perspectives defined , which add their
corresponding views. Now there does exist a view (AView), which
should never be visible in one of those perspectives (BPerspective).
This was no problem until the point was reached, when I added to my
workbench advisor the "Show View" submenu (as shown in
WorkbenchActionBuilder):
private MenuManager createWindowMenu(IWorkbenchWindow window) {
MenuManager menu = new
MenuManager(Messages.getString("action.file.window"), //$NON-NLS-1$
IWorkbenchActionConstants.M_WINDOW);
showNavigatorAction = new ShowNavigatorAction();
menu.add(showNavigatorAction);
menu.add(ActionFactory.RESET_PERSPECTIVE.create(window));
MenuManager showViewMenuMgr = new
MenuManager(Messages.getString("action.window.showView.label "),
"showView"); //$NON-NLS-1$ //$NON-NLS-2$
IContributionItem showViewMenu =
ContributionItemFactory.VIEWS_SHORTLIST.create(window);
showViewMenuMgr.add(showViewMenu);
menu.add(showViewMenuMgr);
return menu;
}
Of course this "Show View" menu is visible in all perspectives (as it
should), but regrettably it is also now possible by the user to select
the forbidden AView in the BPerspective.
My question is: Is it possible to control
org.eclipse.ui.actions.ContributionItemFactory.VIEWS_SHORTLI ST
such that I get the wanted effect? I could of course write my own
ShowViewMenu class, but I assume there does exist a much less
brutal solution.
Thank you very much for your help,
Daniel Krügler

I don't think so. Eclipse doesn't support constraints on what views can
be shown in which perspective. You should enter an enhancement request.

I assume, you mean org.eclipse.ui.activities here? My first step was in
the direction of org.eclipse.ui.perspectiveExtensions until I realized
that it only helps in **extending** the visiblities, not in
**constraining** them (I should have reflected about its name ;-))
I will study the implications and effects of org.eclipse.ui.activities
and provide a more detailed answer if that ext. point proves to be
useful.
Generally I would realize activities/roles similar to actions, which are
a quite related issue, I think.
Thanks for your ideas,
Daniel
