Hi, Is there is a preferred method for updating the model behind a combobox while it is displayed to avoid flicker? Original code did: 1) Clear liststore model, changing the active item! > Combobox redrawn with empty contents 2) Repopulate liststore model 3) Reset active item > Combobox redrawn with active item selected Found these 2 method which avoid flicker redraw: 1) Temporarly block the change signal while reconstructing the model; 2) Create a new model and assign it to the combobox replacing the original. Is one method preferred over the other? Is there another method I should be using instead? Thanks, Mike P.S. If I appear vague it is because the code in in C++ using gtkmm, but I don't think it matters, hence asking in this list. Here's the current broken code from GParted 0.19.1 Win_GParted::refresh_combo_devices() https://git.gnome.org/browse/gparted/tree/src/Win_GParted.cc?id=GPARTED_0_19_1#n578 _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
