Hi, Sorry to bother again, but i am stuck. I have read the stuff about access to user_data in callback methods connected thru signals here: https://live.gnome.org/Vala/SignalsAndCallbacks
However, I cannot get it to work in my project. Again, here is my test code: using Gtk; using Goo; using Gdk; class Bar { private int foo = 1; public Bar (Canvas canvas) { CanvasItem root; root = canvas.get_root_item(); var rect = CanvasRect.create(root,10,10,100,100); rect.fill_color = "black"; rect.button_press_event.connect(on_button_press); } private bool on_button_press(CanvasItem Item, Gdk.EventButton EventButton) { stdout.printf("%d\n", this.foo++); return true; } } class TestCase : Gtk.Window { public TestCase () { this.title = "testcase"; this.destroy.connect (Gtk.main_quit); set_default_size (600, 600); var canvas = new Canvas(); var bar = new Bar(canvas); add (canvas); } static int main (string[] args) { Gtk.init (ref args); var testcase = new TestCase (); testcase.show_all(); Gtk.main (); return 0; } } It should output a number starting with 1 and increasing by 1 every time you press a mouse button on the black rectangle, but it either segvaults or start with a random other number. Any help would be great! Greetz, Fred 2011/7/26 Fred van Zwieten <fvzwie...@gmail.com>: > Hi Luca, > > Yeah, i can imagine. I just pasted the code I had :-) > > Never mind. Thanks for trying anyway.
