get_source_device


Description:

[ Version ( since = "3.0" ) ]
public unowned Device? get_source_device ()

This function returns the hardware (slave) Device that has triggered the event, falling back to the virtual (master) device (as in get_device) if the event wasn’t caused by interaction with a hardware device.

This may happen for example in synthesized crossing events after a Window updates its geometry or a grab is acquired/released.

If the event does not contain a device field, this function will return null.

Parameters:

this

a Event

Returns:

a Device, or null.
