Hi Filip, Thanks for your help ;)
I got it by reading about qtdeclarative/src/quick/items/qquickimage.cpp and I noticed http://comments.gmane.org/gmane.comp.lib.qt.devel/17685 there is only QTouchEvent for MultiPointTouchArea, but NO QTabletEvent for hacker`s TabletSketchArea https://codereview.qt-project.org/#/c/74202/ How to get pressure value for QML application? please someone give me some advice?
