| Just for testing I used a GtkButton and substituted signal enter-notify-event for signal clicked (clicked works). A warning appears: "enter-notify-event is invalid for instance" after g_signal_connect is executed. The callback handler is not called. Simplified: [code] GtkWidget * b = gtk_new_button (); .... g_signal_connect (b, "enter-notify-event", G_CALLBACK (enterleave), myuserdata) ; ... [/code] with callback handler [code] static gboolean enterleave ( GtkWidget * w, GdkEventCrossing * event, char * data ) { printf ( "Now in enterleave callback\n" ) ; .... return false; } [/code] I also tried: [code] gtk_widget_set_events ( b, _ENTER_NOTIFY_MASK ); g_signal_connect (b , "enter-notify-event", G_CALLBACK (enterleave), myuserdata) ; [/code] and also signal "enter" (deprecated), but result was same. Cannot see what is wrong, so help would be most appreciated. |
