Hello,

I created a program with Glade, produced a GtkEventBox and included it with glade_xml_new in the program.

I would now like the position of the mouse query when the button was pressed.
Is there somewhere an example?

I Use:
Glade 3

Greetings, Satyria

Hello, I've found a way and my problem is solved.

Also:

In the file galde were deleted the events (which makes sense for this?).
In the source code, I have added these lines:

Code: (C)
1 2 3 4 5 6 7 8	area = glade_xml_get_widget (xml, "drawingarea"); parray g_ptr_array_sized_new = (5000); gtk_widget_add_events (area, GDK_BUTTON_PRESS_MASK); g_signal_connect (G_OBJECT (area), "button_press_event" G_CALLBACK (button_pressed), parray);

And this feature:

Code: (C)
1 2 3 4 5 6 7 8 9 10 11	static gboolean button_pressed (GtkWidget * area, GdkEventButton * event, Parray GPtrArray *) ( int x, y; x = event-> x; y = event-> y; g_print ( "Der Button wurde bei %i %i ausgeloest\ n", x, y); return FALSE; )
