The "item-created" signal is only available in the Model/View variant, but this may be deprecated?! Any ideas?In the demo (demo/demo.c) it calls a function after adding each item like this: item = goo_canvas_rect_new (root, 20, 30, 50, 30, "stroke-color", "red", "line-width", 8.0, "tooltip", "Red stroked rectangle", NULL); setup_item_signals (item); static void setup_item_signals (GooCanvasItem *item) { g_signal_connect (item, "motion_notify_event", G_CALLBACK (on_motion_notify), NULL); g_signal_connect (item, "button_press_event", G_CALLBACK (on_button_press), NULL); g_signal_connect (item, "button_release_event", G_CALLBACK (on_button_release), NULL); } That's probably the easiest thing to do.

Thanks for the answer, but not the thing I had in mind...
As I said, I'm trying to implement a CanvasEditor class (inherited from the GooCanvas) and
I want an easy way to connect each item I'll add to the editor to the Editors event handlers.
I other words, I want to use the "goo_canvas_rect_new(root,...)" function with my CanvasEditor
root item and all signal handlers should be added automatically.
