I am looking to know what is the best practice to make a window which the content changes, but without changing the window. Something like using tabs, but with no tabs, controlled with buttons.
What widget should i use to archive what i need?
And if you don't mind the little off-topic, should it be drawn manually or with a GUI designer like glade? It is meant to be used within python.
If you can use GTK 3.10, take a look at GtkStack and GtkStackSwitcher. If not, use GtkNotebook and set the show_tabs property to False, then build your own buttons.
