PyGTK

PyGTK is loads better than TKinter. There are far more events to work with which let you make a more responsive, convenient, and concise interface.
Supposedly you should use the GtkBuilder file format over Libglade. With that in mind...

Loading a glade file into a python program
import gtk gladefile = 'app.glade' builder = gtk.Builder() builder.add_from_file(gladefile)

But first you have to create the glade file. Create a window and divide it with boxes

ComboBox

glade side	adding items, pygtk side
Create a ListStore for the model Add a column to the ListStore on the General tab. gchararray for strings Create a ComboBox Set the model to the ListStore Right click the ComboBox in the widget tree and click Edit On the Hierarchy tab, click add. Name it whatever. Set the Text property to the column you want displayed from the ListStore
