The GTK+ Input and Event Handling Model
API Classes
Please note that the GTK+ API is split into two logical components: "GTK" and "GDK". The former provides high-level widgets and abstractions, while the latter wraps low-level functions provided by the native windowing system. Most tablet APIs are part of the latter GDK namespace.
