Re: resizing problem

[Jan-Marek Glogowski <glogow fbihome de>]

Hi

I had a quick glace at the code:

1. Please use TRUE and FALSE, instead of 1 and 0 where the function
   parameter is gboolean.

2. line 208:
-       gtk_box_pack_start(GTK_BOX(vbox), menubar, 0, 1, 0);
+       gtk_box_pack_start(GTK_BOX(vbox), menubar, TRUE, TRUE, 0);

will do a correct resize of the drawing area.

3. Info: Since v2.4 GtkItemFactory has been deprecated in favour of
   GtkUIManager.

4. The config event is a simplification, but since you do a resize in your
   config event you should use GtkWidgets "size-request" and
   "size-allocate".

This is the idea: On a resize "size-request" is called. Now you should
adjust the "resize requisition" to your preferred size / ratio / whatever.

Then "size-allocate" is called with the adjusted size.

Now do your calculation based on the new size.

Then your "expose" handler get's called. For a simple example see
gtklabel.c from the Gtk sources.
