Adding a context menu like in the Eclipse Views [message #465712] Tue, 20 December 2005 11:33 Go to next message

I need to add a context menu to a toolbar, to get a similar look and
feel like the arrow-pointing-down in various Eclipse views. For example
the Package Explorer's toolbar has a button on the right which on
mouse-down displays a menu (with items such as Show, Select working set
etc). How is this implemented?

I couldn't dig deep enough into the Eclipse source to see how this is
implemented, but my first attempts were to add an Action to the Toolbar
with the image as icon and then I try to add a mouse listener to the
item. However, at the point when I want to add the listener, the
corresponding Button control is not created yet.

Any ideas - thanks!
Hans

If you use the wizard to create a plugin project and use the "with a view
template", that has the view menu and toolbar actions. You should be able
to get the code from there.

These use the IActionBars from the view's site. This object already has
a menu manager built-in, and I find it difficult to track (in the
Eclipse source code) where this is ultimatively defined/implemented.

http://www.eclipse.org/swt/snippets/
under "ToolBar, ToolItem" is "place a drop down menu in a tool bar"

this will, however, create a toolbar with a down arrow centered
vertically. to get it more like the eclipse view's, AFAIK, you'll have
to use your own icon (make it 9x16 pixels) by changing:
final ToolItem item = new ToolItem (toolBar, SWT.DROP_DOWN);
to
final ToolItem item = new ToolItem (toolBar, SWT.FLAT);
and then setting the image with item.setImage(image)

Thanks, Jeremy. The snippets page is a very useful reference. Your
suggestion with the smaller image is good (actually 10x16 is the correct
size).

However, the remaining problem is that I don't see how I can react on
SWT.MouseDown - the only event that seems to work is SWT.Selection.
SWT.MouseDown does not seem to trigger any event.


final ToolItem item = new ToolItem (toolBar, SWT.FLAT);
item.addListener(SWT.Selection, new Listener () {
public void handleEvent (Event event) {
openContextMenu(toolBar, item);
}
});

Hans,
thanks for catching this - I breezed right by once the menu was
dropping where I wanted it!

upon further inspection, the only solution I'm seeing is adding the
mouseDown listener to the toolbar itself and checking to see if the
item's bounds contain the event's x & y coordinates:

toolBar.addMouseListener(new MouseAdapter() {
public void mouseDown(MouseEvent e) {
if(item.getBounds().contains(e.x, e.y)) {
openContextMenu(toolBar, item);
}
}
});

any other thoughts?

Hello Hans,
Inside of the View class you can get a reference to the MenuManager via:
getViewSite().getActionBars().getMenuManager();
Then you can add your actions to this MenuManager and you will have a little
down arrow icon on the top right of your view. Hope this works.

Yes, this is working! Thanks a lot. I expected to be a more
standardized solution for this in Eclipse, but I don't care as long as
it does what I need. It is still a mystery how this is implemented in
the standard Views...

This would work, but I am not inside of a View but have a
custom-tailored composite on a ScrolledForm. Thanks anyway.
