specify which child widget to be on top in GtkFixed?!
greetings,
I'm having trouble with GtkFixed and their children, how can I specify
which child widget to be on top. In the code snippet below no matter
were I create the TextEntry it always get drawn on top of the other
widgets! how can specify which child widget to be on top of the others
at run time / or at compile time.
regards,
ferar

Re: specify which child widget to be on top in GtkFixed?!
Widgets dont overlap in GTK+, instead one widget is packed into another
widget and sits along side other widgets inside its container - who packs
them in a way that they will not overlap.
FYI, GtkFixed is a special case widget you dont want to be using if your
application has any resize capabilities at all (yes, GtkFixed places widgets
on top of eachother when you forgot to place them with enough space between
them, because GtkFixed assumes you are using all the width/height available;
but there is no conceptual Z coordinate).
If you need to have widgets that overlap, you might consider using a canvas
api (like goocanvas for instance), or maybe use clutter.
Cheers,
-Tristan
