How can I add a context menu to an editable CCombo??
The following standard way doesn't work:

CCombo combo = .....; //Creating the editable combo

MenuManager menuManager = new MenuManager("#PopUpMenu");
menuManager.setRemoveAllWhenShown(true);
menuManager.addMenuListener(new IMenuListener() {
public void menuAboutToShow(IMenuManager manager) {
manager.add(new Separator(IWorkbenchActionConstants.MB_ADDITIONS));
manager.add(new SearchAction(combo, group, parent.getShell())); // the
self written action
manager.add(new Separator(IWorkbenchActionConstants.MB_ADDITIONS +
"-end"));
}
});
Menu menu = menuManager.createContextMenu(combo);
combo.setMenu(menu);

The problem is that the menu from the underlying text field of the combo
will be shown instead the menu set on the combo.

This is a bug in CCombo. Please enter a bug report against Platform SWT.

The bug is that when you call CCombo.setMenu(), the menu is being set on the
Composite that encapsulates the Text and Button. However, this composite is
completely obscured by its children so the menu can never be shown.

The fix is to override CCombo.setMenu() and set the menu on the Text widget
inside. There is no way for the application to work around this
unfortunately.
