This is used by the Connection to toggle all touchpad devices on/off<br />
when the touchpad key is pressed. This is a hard coded key and not<br />
mapped to a global shortcut (maybe it should?).</p>
<p>Detecting what is a touchpad is unfortunately not tivial. The code<br />
uses the following approach:</p>
<ul class="remarkup-list">
<li class="remarkup-list-item">it's a pointer</li>
<li class="remarkup-list-item">it's not also a keyboard or touch screen</li>
<li class="remarkup-list-item">it's at least one of the following:<ul class="remarkup-list">
<li class="remarkup-list-item">supports multiple tap fingers</li>
<li class="remarkup-list-item">supports disable while typing</li>
<li class="remarkup-list-item">supports disable on external mouse</li>
</ul></li>
</ul>
<p>If the code finds a touchpad and changes it's state successfully,<br />
it triggers the touchpadEnabledChanged on Plasma's osdService.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>Tested on notebook with toggle touchpad button</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>rKWIN KWin</div></div></div><br /><div><strong>BRANCH</strong><div><div>toggle-touchpad</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D1545" rel="noreferrer">https://phabricator.kde.org/D1545</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>input.cpp<br />
