Hard to say whats going on here, I wonder who is responding
to the size requests for these items which are getting drawn.
It seems you connect to a signal to draw on a widget, which
means the content is not the widget, so probably you need
to also connect a signal to override the size request of the
said widget you intend painting onto ?
Perhaps you are using forced size requests to accomplish
this (using gtk_widget_set_size_request() or such), and
have somehow mixed up the size requests while swapping
your content onto new rows/columns ?
Other than that, child 'expand' properties will be considered
by the GtkTable (if all children can expand, then it's quite
possible that after reaching a large window size the content
will be evenly spread).
