No, I don't think a GtkTreeview can display this sort of structure. However, this sort of layout can perfectly be achieved by utilizing a GtkTable (instead of GtkTreeview). The "Row Span" property of cell widgets in a GtkTable is to be set here. It's the very same as in HTML 4 tables, for instance. By doing this you're also not limited to simple drawn items like texts or bitmaps in the cells but can easily put any widget into them, i.e. buttons. To get closest to the appearance you sketched I suggest to use a GtkLabel in a GtkFrame for each cell. Main drawback is that if you're about to use more than 50 rows like this via a GtkTable, some performance degradation may start to take place. But for structures with limited numbers of cells this is negligible. Btw, GtkTable should be put into a GtkScrolledWindow, to handle the situation when there are more rows (or columns) to be displayed than the window dimensions allow - offer scrollbars in that case. It's the same way original GtkTreeViews work. I already created an example of your desired layout type but I'm afraid its Glade XML or .c code is a bit too long to include here (~10 KB). _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
