Hi,

But I just wrote an GTK+ Application and this warning occures.
I had to emit a signal to an Event-Box by hand.

Code: (C)
1 2 3 4 5 6 7 8 9 10	// this is my signal connect g_signal_connect( GTK_OBJECT( button_help_event ), "button_press_event", G_CALLBACK( button_help_fkt ), NULL ); // here i want to call the signal by hand g_signal_emit_by_name( G_OBJECT(button_help_event),"button_press_event"); // and this is the warning (test:5862): GLib-GObject-WARNING **: gsignal.c:2217: value location for `gboolean' passed as NULL

Can anyone help me fixing this problem?
Or do I have to emit a signal different as I do now?

Thx,

Look at this documentation: http://library.gnome.org/devel/gobject/unstable/gobject-Signals.html#g-signal-emit-by-name

button-press-event has a return type of gboolean, so you need to provide a place for it!
