Add a pull-down menu to an existing view's toolbar [message #294667]

Hello,

With the available article, I am able to add menu items and toolbar icons
to an existing view, and I can create pullover submenus. However, I am
not sure how to make my new toolbar icon a pull-down menu. I can do that
for the main toolbar of the Workbench window using actionSets since it has
a "pulldown" property that I can set to true. For contributing to
individual view, the action in org.eclipse.ui.viewActions does not have
the same property. Any suggestion will be appreciated. Thanks!

Michael

Officially, you can't do it. In 3.2 M4 or 3.2 M5 you should be able to
using the "org.eclipse.ui.menus" extension point.

However, you might be able to get away with it by adding the following
attribute to your action (ignore any warnings or errors that are
displayed).

style="pulldown"

I'd love to hear whether that works for you.

cheers,
d.

Thanks Douglas! A drop-down arrow did appear with your suggestion! The
only thing I'm not sure now is if I should still implement
IViewActionDelegate since there isn't a local toolbar equivalent of
IWorkbenchWindowPulldownDelegate. Do I need to add mouse listener then to
draw the drop-down menus when the arrow is clicked?

Again, this is just a hack: no promises this will work in any future version
of Eclipse. Also, this forces your plug-in to be loaded eagerly, which can
cause performance problems. But, you can change your selectionChanged to
do the following:

public void selectionChanged(IAction action, ISelection selection) {
// Do whatever else you need to do.

// Hook up a menu creator
if (!menuCreatorSet) {
action.setMenuCreator(new IMenuCreator() { // for view menu
public Menu getMenu(Menu parent) {
Menu menu = new Menu(parent);
MenuItem menuItem = new MenuItem(menu, SWT.PUSH);
menuItem.setText("Monkey");
return menu;
}

public Menu getMenu(Control parent) { // for tool bar
Menu menu = new Menu(parent);
MenuItem menuItem = new MenuItem(menu, SWT.PUSH);
menuItem.setText("Monkey");
return menu;
}

public void dispose() {
// Do nothing
}
});
menuCreatorSet = true;
}
}

cheers,
d.
