SUMMARY Currently, it isn't possible to show the toolbar of the presentation mode by moving the stylus to the top left. If you move the mouse there, it works. However, there are 2-in-1-devices where you can't access the mouse to open the toolbar. If the stylus isn't pressed against the screen (but within reach), the toolbar should be shown. STEPS TO REPRODUCE 1. Open a file in presentation mode 2. go to top left with a stylus pen (wacom etc) OBSERVED RESULT the toolbar doesn't open EXPECTED RESULT the toolbar should open
Could you please state your Qt version? Old versions had a bug that prevented stylus hover events to be converted to mouse hover events.
You get the toolbar when moving the mouse on the top 2 pixels of the screen (see presentationwidget.cpp:841). Stylus events do get translated to mouse events, and therefore I can get the toolbar with a stylus by touching the screen on the top two pixels. AFAIK mere hovering of the stylus is not considered.
Ahh, ok. If I aim really close on the top and press (I mean really close, ca. 1mm) it opens. However this is really difficult, especially in a presentation situation. My QT-Version is 5.14.2. When hovering over the screen, a crosshair is shown. After a bit of testing around, the toolbar indeed opens with just hovering the pen, but the area in which this is activated is so small, that you basically can't open it (I have a 1920x1080 screen, height approx. 17.5 cm. Two height pixels are only 3mm tall.) I suggest that when hovering with a pen, the toolbox should open, as soon as the pen is in the top x pixels, where x is the height of the toolbox when opened. If the stylus is pressed on the screen (when drawing etc) it should not open.
I like the suggestion from Comment 3. Alternatively, there could be a menu button in the top left corner, which is always shown. That button would open the toolbar, then the toolbar covers this button. I think it would make sense to keep the toolbar open (sticky) when it is explicitly opened by clicking this button. To close it, it would have a close button in the left corner. Someone who does presentation should decide whether such a button is aesthetically acceptable.
