The top window has a menu and a single textview. This window uses all of the
available area on the screen, but sometimes it has to make room for a dialog
window that that needs to be just below. When the dialog window is no longer
needed the top window should expand and reclaim the space at the bottom.
I want to do this by reducing and increasing the height of the top window by
the program, but I cannot make it work.
Setting top window:
[code]
...
gtk_window_set_title (GTK_WINDOW (window), title );
gtk_widget_set_size_request (window, wdavail, htsrcwnd ); // request works
gtk_window_move ( (GtkWindow *)window, 0 , 0 ); // works
...
gtk_widget_show_all (window);
[/code]
Reducing height of top window:
[code]
...
gtk_widget_set_size_request (window, wdavail, reducedheight ); // request
ignored
...
[/code]
So, the height of the top window remains as initialised.
I can destroy window by gtk_widget_destroy and then recreate another top window
with reduced height and then place the dialog window at the bottom. However,
this is ugly and irritating because the top window destroy and immediate
recreate are clearly visible.
How can I make the transition a bit smoother?
