Once a row got its size calculated and allocated, it will not change unless the data in the model changes (signaled via row-changed). When GtkTreeView receives row-changed for a row, it will recalculate the requested height for that row by re-querying the cell renderers. Apart from this, cell renderers cannot influence the height of the row. > I want to know how to ask the cell to request more space.

The easiest solution is to emit the row-changed signal (using gtk_tree_model_row_changed()) once the row has to update its height. regards, -kris. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
