[Bug-gnubg] changing GTK label from callback

[Holger]

Hi,

does anybody know how one can update a GTK label from a signal callback? 
Just gtk_label_set_text doesn't seem to work.

I've tried to fix "[bug #4288] Incorrect path to MET", showing the MET 
filename under settings|options|match. After loading a new table I try to 
change the label text from SetMET(). But it doesn't want to. :( I've even 
tried:

extern void SetMET( gpointer *p, guint n, GtkWidget *pw ) {
...
    if ( p && GTK_WIDGET_VISIBLE( p ) ) {
        gtk_label_set_text( GTK_LABEL( p ), miCurrent.szFileName );
        /* the following shouldn't be necessary */
        gtk_widget_queue_draw( GTK_WIDGET( p ) );
        gtk_widget_queue_draw( gtk_widget_get_toplevel( GTK_WIDGET( p ) ) );
        gtk_widget_show_all( gtk_widget_get_toplevel( GTK_WIDGET( p ) ) );
    }

Regards,

        Holger
