Some things I noted: The window for which the warning is issued is, indeed, the top-level window. it seems that horizontal oversizing does not cause this. When the iter is expanded, this warning does not appear (as long as window is *high* enough to contain the expanded data.) If the window is high enough to display all of "List 2", then if it is expanded first, then expanding "List 1" does not seem to cause the warning to be displayed (from my limited testing). So.. is this a bug in Gtk3? I'm not even trying to resize the top-level window.. All I'm doing is expanding the treestore to be able to scroll through the data. The list of the real data I'm working with is too long to fit onto the screen anyway. If this is, indeed a bug, would anyone want to file a bug report?
