The following partially works and I post in the hopes that someone might get an idea that will fix my issue :)
bool ZoomCode::event(QEvent *event)
{
if (event->type() == QEvent::NativeGesture) {
return gestureEvent(static_cast<QNativeGestureEvent*>(event));
}
return QWidget::event(event);
}
bool ZoomCode::gestureEvent(QNativeGestureEvent *e) {
float value = e->value();
textEdit->setFontPointSize(NULL); // zoom does not work without this
textEdit->selectAll(); // some part of the text has to be selected before the zoom in the text starts to work. It does NOT matter if it is the WHOLE text or just a character in the text, just as long as something gets highlighted. Afterwards, nothing has to be highlighted again for the zoom to work. The zoom works on the whole text, no matter what part has been highlighted.
if(value >0) {
zoomIn(value + 5); // + 5 to add some zoom strength
} else if(value < 0)
zoomOut(value - 5); // -5 to add some zoom strength
}
}
