This tutorial shows the various methods to arrange widgets in a window,
and tells you how to choose the right one.
If you previously did your GUIs in Visual Basic or Visual C++, you will
wonder why you'd need a tutorial on widget placement. Until now it was like
this: Size the window, select a widget and position it at a
(x,y) position and make it this wide and that high -
nothing more, totally easy. You have fixed positions and sizes, but they
stay on their place even when the window size is changed - they don't
adjust themselves because they don't know how.
In Gtk, things are dynamic: Widgets adjust their sizes when the window size
changes, except you explicitely tell them not to do so. Setting things up
is a bit more complicated than just fixing sizes and positions, but you
are rewarded with a flexible window that can be sized to nearly any size,
while still looking good.
