KeyboardInputRedirection and Xkb. KeyboardInputRedirection registered<br />
the global shortcut and did the handling for layout switch and config<br />
changes. Xkb did the notification on layout change.</p>
<p>Layout changes can nowadays be detected through an InputEventSpy. It<br />
can only happen after a key change or an explicit layout switch. Thus<br />
it does not need to be in Xkb anymore which allows to reduce Xkb to<br />
only care about the Xkb keymap and state tracking.</p>
<p>This change introduces a new class KeyboardLayout which is an<br />
InputEventSpy and takes over the task of the layout change notification<br />
from Xkb and the layout management from KeyboardInputRedirection. Thus<br />
everything related to management of keyboard layout is together in one<br />
class.</p>
<p>This allows in future to add unit test to it (requires further cleanup<br />
of Xkb to be able to use it and drop the InputRedirection dependency) and<br />
opens the possibility to also take over keyboard layout management on X11<br />
for the Plasma desktop.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>Manual testing</p></div></div><br /><div><strong>BRANCH</strong><div><div>keyboard-layout</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D4135" rel="noreferrer">https://phabricator.kde.org/D4135</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>CMakeLists.txt<br />
