> Hello all,
> I am trying to implement a gtk.Button which can be resized (by grabbing it
> near its nower edge) and dragged around (by grabbing it somewhere near its
> center). The gtk.Button is placed inside a gtk.Layout. I could get this to
> work by responding to mouse events WITHIN the Button.
> However this had the drawback, that the mouse may be too fast while resizing
> and the gtk.Button will not grow fast enough. Thus the mouse will leave the
> area of the gtk.Button and no more motion events will be sent to the Button.
> When moving the Button around this problem is less obvious, because the mouse
> is less likely to leave the area of the Button. None of these problems became
> apparent on my desktop box, but on my maemo handheld, the resizing simply
> didn't work.
> So I thought, I'd better let the gtk.Layout handle the motion events. The
> strange thing is: it gets motion events only
> - When the mouse is outside any gtk.Button
> - When the mouse is inside a gtk.Button but no mousebutton is pressed
> However no motion events arrive at the Layout when
> - The mouse is inside a gtk.Button and a mousebutton is held pressed
> I found two postings related to this issue:
> - one had the exact same problem, but there were no replies
> - it was said that gtk.Layout does not respond to events, as it does not have
> its own window. This is hard to believe, because my Layout does respond to

Couldn't you look at (mouse) events for the whole window?!
(I'm assuming that you know about gtk.HPaned and gtk.VPaned but find
them ugly for your purposes)
