<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;"><p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I am trying to fix the following papercut: I regularly write on pdf files in presentation mode, using the pen that comes with my Lenovo ThinkPad Yoga. When I approach the screen with the pen, the cursor appears, and it follows the pen tip during writing. When I lift off the pen, the cursor stays on, and auto-hides only a few seconds later (because of Okular::Settings::EnumSlidesCursor::HiddenDelay). As a consequence, the cursor frequently hides the last bits of what I have just written. This is a nuisance, because I do this in front of an audience, and a lot of it is math (where every detail matters).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Ideally, the cursor would auto-hide when I lift the pen off the screen. Luckily, Qt has an event for this: QEvent::TabletLeaveProximity. Unluckily, the documentation says (http://doc.qt.io/qt-5/qtabletevent.html):</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">"TabletEnterProximity and TabletLeaveProximity events [...] are only sent to QApplication"</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Therefore, this patch introduces a new class TabletApplication, which inherits from QApplication, and is used in main.cpp instead of QApplication. The proximity events are really caught, and each time a short note is printed on the console.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Unfortunately, at this point I am stuck and need some help. Apparently, I cannot control the cursor from a QApplication. How do I get the information that a TabletProximity has been caught to the presentation widget? Maybe the answer is trivial, but I have very little Qt programming experience. Thanks for your help!</p></pre>
