switching, but this proved contentious because it can cause user<br />
frustration over accidental tab switching when moving from the tab<br />
bar to the list view at angle, grazing another tab.</p>
<p>This patch implements a triangle filter to get the best of both<br />
worlds. When the mouse motion vector is within the triangle from<br />
the vector starting coordinate pair to the relevant tab bar<br />
corners, the original 250ms delay remains in use. When the vector<br />
is outside the triangle, tabs are switched immediately - improving<br />
even over the 50ms delay proposed in <a href="https://phabricator.kde.org/D11848" style="background-color: #e7e7e7;

<p>Care is taken so that tab switching is always immediate when the<br />
tab bar is freshly entered, e.g. moving from the panel to Kickoff.</p>
<p>As a small advantage this removes a MouseArea item from each tab<br />
button.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R119 Plasma Desktop</div></div></div><br /><div><strong>BRANCH</strong><div><div>master</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D13192">https://phabricator.kde.org/D13192</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>applets/kickoff/package/contents/ui/FullRepresentation.qml<br />
