I am sure this is simple but I haven't figured it out yet. I have a widget in a GtkExpander, when I collapse the expander I would like my window to resize to reclaim the space. How is it done?

Hmmm. I know that if you were to make the window fixed using gtk_window_set_resizable(GTK_WINDOW(window), FALSE) then the window would react (snap closed around) the GtkExpander widget. However, I don't know how this would be done with a sizable window.

Furthermore, if you are using a resizable window, changing it's size programatically in response to the GtkExpander may prove annoying to the end user as they could potentially have sized the window to a preferred size.

If you get the height of the GtkExpander's child, then you could possibly just subtract that height from the height of the window when it is contracted. Then, do the same thing when it is expanded again. You have to do this because GTK+ will only resize the window after created unless necessary.

Thanks for the suggestions. Making the window fixed works great with GtkExpander, however I would like the users to be able to resize the window. I tried Andrew's method of setting a new size based on the widow's size - child's size using gtk_window_resize(). Then I invalidate the window using gtk_widget_queue_draw_area(). However this has no effect. Is there a better way to get the window redrawn?
