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?
