The event mask for a window determines which events will be reported
for that window from all master input devices. For example, an event mask
including GDK_BUTTON_PRESS_MASK means the window should report button
press events. The event mask is the bitwise OR of values from the
GdkEventMask enumeration.
See the [input handling overview][event-masks] for details.
