Summary: The signals emitted by LibInput::Connection carry the Device for which the input event was received. This Device is passed to the input handlers. Custom event classes are added which extend QMouseEvent, QKeyEvent and QWheelEvent respectively and expose the Device. The Device is only passed around as a forward declared pointer, so even if compiled without libinput support, it should still compile. Event handlers which need to get access to the Device can now just cast the event pointer to the custom class and access it. This can be used in future to handle device specific key codes, etc. As we don't have a proper event classes for touch events the event handlers do not yet have access to the Device. Here the internal API needs to be adjusted in future. Reviewers: #plasma Subscribers: plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D1667
