Hi all, Is there a way to know which button was pressed if they share the same callback function:

Code: (C)
1 2 3 4 5 6 7 8 9 10 11	void box_clicked (GtkButton button, GPuntos pGame) { // need to know which button was clicked, so I can use GPuntos structure } // .. later g_signal_connect (G_OBJECT (box1),"clicked",G_CALLBACK (box_clicked), game); g_signal_connect (G_OBJECT (box2),"clicked",G_CALLBACK (box_clicked), game);

thanks :)

Your box_clicked function receives a pointer to a button. So box_clicked could test a property of the button, for example its label or name.

To set/get a widget's name, use:
