AA_SynthesizeMouseForUnhandledTabletEvents not supported anymore? [Qt 5.12.2 LTS]]

[nen777w]

Recently I found that QTabletEvent no longer converts to QMouse events, for Qt 5.12.1. Is it a bug or a feature? And, if it's feature how to enable back-compatibility?

Hi,

You should check if this situation still applies with more recent versions of Qt like the latest LTS as well as Qt 5.14.

Hi
So the line
QApplication::setAttribute(Qt::AA_SynthesizeMouseForUnhandledTabletEvents, true);

does nothing ?

Looks like it's but only in Qt 5.12.2, I moved to Qt 5.14.0 and the situation is changed, but...

Exist difference with a long-press, between how it works with Qt 5.11.2 and Qt 5.14.0.
In Qt 5.14.0 if you long-press, the Qt drawing circle around the point and then show (or not show) context menu in Qt 5.11.2 it's not happening.

And sometimes the new behavior is fairly not convenient. For example, if you try to drag sliders.
And it's not clear how to disable it?

IIRC, there has been some work with regard to input handling. You should check the bug report system to see if there's anything related.
