Re: Develop a composite widget

[Jeroen Benckhuijsen <jfbenck home nl>]

You made an error in the declaration of the widget structure (struct
_GtkSwap). The first element (the parent of this widget) should be an
GtkScrolledWindow scrolledwin, not a pointer to a widget. The parent of
a widget should always be the first element of the new widget, and it
should be that widget itself, not a pointer to that widget. You could
use a program to generate this code for you. There are programs which
generate this code for you, simply be setting some parameters. One of
them is Gwf (http://gwf.sourceforge.net). Have a look at it! Especially
when desinging a lot of widgets it saves you a lot of work. Any problems
with it : mail me (i'm the author of the program).
