hi i went through the source code and made a conclusion that only container widgets can move the focus between its children. Is it so, or i m missing something.
I would also like to know if i want to make arrow key behave as tab key, how it can be done. I know that it can be done in application written using Gtk but i want to make changes in Gtk source code. I tried adding bindings to GDK_Right with move_focus signal and GTK_DIR_TAB_FORWARD as direction but unable to get it done and i know that i have done something terribly wrong but couldn't think of any other solution. May be some one can provide a hint in this context. bye varun muppet wrote: > > > On Jul 18, 2007, at 9:02 AM, varun_shrivastava wrote: > >> so which of the GtkWidget "focus" signal handler is being called >> the default >> one or the overridden one in GtkContainer class. > > An overridden handler always gets called, and has the option to chain > up to the default. > > gtk_container_focus() handles two cases: 1) the container itself can > take focus, and 2) the container cannot take focus, but perhaps its > children can.
