Re: [gtk-list] NEWBIE: Getting a Handle to an entry.

[Kent Schumacher <kent structural-wood com>]

One solution (of many) is to attach data to the button widget.


gtk_object_set_data(GTK_OBJECT(button),"WIDGET",&address_of_widget)

You can then retrieve the data from the widget (which is passed to the callback
function) using

address_of_widget = gtk_object_get_data(GTK_OBJECT(widget),"WIDGET")

(Semantics may be slightly wrong - conceptually it's right)
