[pygtk] query-tooltip problems

[Gary Jaffe]

I'm sorry, I guess I wasn't very clear.

I want to take a transient window containing just a gtk.TreeView inside 
a gtk.Scrolled and temporarily expand it to the full height of the 
screen when the user hovers the pointer over the window.

I agree that just looking for the pointer to enter the window without 
any delay would be annoying to the user.  I was hoping that I could do 
this easily by catching the query-tooltip signal, but that signal seems 
to be triggered as soon as the pointer enters the window.

So my question is: is there some signal I could catch when a tooltip is 
displayed just to get the timing right for expanding my window.  I'm not 
actually interested in the tooltip at all.  Or do I have to set a timer 
and keep checking the position of the pointer after it enters the window 
to determine when the pointer has been stationary over my window for at 
least 0.5 sec?

Thanks,
Gary
