Re: GTK Signal Definitions

[Bryan Christ <bryan christ hp com>]

"configure-event" partially works.  Basically, I am trying to maintain the width of a pane in a GtkHPaned after the user resizes or maximizes the window.

When I stretch the edges in 90 degree angles (stretch the right edge right, top edge up, etc..) it works fine.  However, when I stretch diagonally or maximize, it does not work.  In my callback for "configure-event" I tried to returning TRUE to stifle the signal propagation.  As expected, my pane was being correctly sized, but not propagating the signal had adverse effects elsewhere--as you can imagine.  Below is my implementation.

g_signal_connect(dialog,"configure-event",
    G_CALLBACK(resize_setup_menu),(gpointer)hpane);

g_signal_connect(dialog,"window-state-event",
    G_CALLBACK(resize_setup_menu),(gpointer)hpane);

gboolean resize_setup_menu(GtkWidget *widget,
    GdkEventConfigure *event,gpointer anything)
{
    gtk_paned_set_position(GTK_PANED(anything),128);
}
