Multiple views, one model

This example shows the powerful of the Observer pattern.

Here both the glade-based and manually built versions are being run at the same time, with a single instance of class MyModel shared between those two versions. The execution of this example results in two windows being displayed; by clicking the button of one of them, the counter is incremented, and the labels in both of them are updated.
