Custom Widget in Drop Down Menu [message #444142]

Hi!

Is there any way of creating a drop down menu which contains a widget and
not only text, something like a TableViewer (for instance).
It may seem a little strange, but I need it to create a calendar button,
something like the one that pops up in KDE/Windows when you click the
clock.
I am using SWT 3.0.1.

Thanks in advance,
LL

Nope. Menus are not native controls on some operating systems (Windows) and
therefore cannot be treated as such. On Windows, the operating system calls
that resize and position controls for example will not work on menus. This
is the main reason that menus are modeled the way they are in SWT.

And presumably there's no way to show a dialog with
the modality of a menu, so that it disappears when
something else gets focus etc.?

Sure, just not inside a menu. Just code a focus listener and close your
shell when it loses focus.

Many thanks for the encouraging tip; before I have a go,
has anyone else emulated popup menus like this? I'm not
sure about cross platform issues; in Windows, Esc also
cancels a popup, and I don't know about other platforms.
I'd like to do it properly...
