Re: How to stack widgets or GtkFixed doesn't seem to work well for stacking

["Matt Hoosier" <mwhoosier gmail com>]

I'm a co-worker of the original poster on this thread. Part of the
trouble with using a new dialog is that it allocates a new X11 window,
which is not guaranteed to be alpha blended with the parent window.
Platforms with a compositing X server support this, but that's a
little more difficult to get with a minimalistic X server on embedded
devices.
