gtk-widget-device-enabled (widget device)

widget -- a gtk-widget object
device -- a gdk-device object
enabled -- a boolean whether to enable the device

The gtk-widget-device-enabled function returns whether the device can interact with the widget and its children. The (setf gtk-widget-device-enabled) function enables or disables the device to interact with the widget and all its children.

It does so by descending through the gdk-window object hierarchy and enabling the same mask that is has for core events, i.e. the one that the gdk-window-events function returns.
