Popup Menu Dialog with GtkMenu Class

Marc Quinton over a post in PHPGTK shows a way to build a popup menu supporting event registration from a GtkWidget. He informs you that menu items are passed to the class constructor as a list of labels. This class emits activate signals with full context.

He gives the details in the following points:

• Create Gtk standard stuff,
• Create a Popup menu in a single a simple line with three items (Edit, Cut, Paste),
• Connect an ‘activate’ callback
• Some items can be insensitive depending on application context,
• Set parent widget; this widget must contain a Window to register some buttons events. No warning about that in this current code, but could be done,
• Look at activate callback; complete event context is available, containing (x,y) coordinates ; may be useful in some usages.
