Hi All,
Am a newbie to linux gtk programming.I want trying to send the mouse button press event to my widget and so I tried this code:

Code: (Plaintext)
1 2 3 4 5 6 7 8 9 10 11	guint signalid = g_signal_new("button_press_event", G_TYPE_FUNDAMENTAL(0), G_SIGNAL_RUN_FIRST, NULL, NULL, NULL, NULL, G_TYPE_NONE,0); g_signal_emit(GTK_OBJECT(gPage),signalid,0);

Can someone tell me what is wrong out there?
Thanks in advance.

Use g_signal_emit_by_name(). Your widget already has that signal installed if you derive it from GtkWidget.

I have tried it already but it gives a Segmentation fault!!
I have now even tried gdk_event_put but nothing seems to work.

I have used gtk_widget_event and it is posting the GDK_PRESS_EVENT properly.
But if i post PRESS and RELEASE events in succession only PRESS event is posted to the widget.the RELEASE event seems to vanish somewhere.
Any clues as to why this is happening.
