use the forum search or google search.
I am pretty sure you will find such a simple answer out by your own... -
I have tried a few examples I found on google but without success. I think I have a problem differentiating the stylus events from the touch events. Here is the code :
bool TabletApplication::event(QEvent *event)
{if (event->type() == QEvent::TabletEnterProximity || event->type() == QEvent::TabletLeaveProximity) { m_canvas->setTabletDevice(static_cast<QTabletEvent *>(event)); return true; } if(event->type() == QEvent::Gesture){ QMessageBox::information(main_window, "Test Message", "swipe triggered"); return gestureEvent(static_cast<QGestureEvent*>(event)); } if(event->type() == QEvent::Gesture){ QMessageBox::information(main_window, "Test Message", "swipe triggered"); return gestureEvent(static_cast<QGestureEvent*>(event)); } return QApplication::event(event);
}
bool TabletApplication::gestureEvent(QGestureEvent *event)
{if (QGesture *swipe = event->gesture(Qt::SwipeGesture)) swipeTriggered(static_cast<QSwipeGesture *>(swipe)); /* else if (QGesture *pan = event->gesture(Qt::PanGesture)) panTriggered(static_cast<QPanGesture *>(pan)); if (QGesture *pinch = event->gesture(Qt::PinchGesture)) pinchTriggered(static_cast<QPinchGesture *>(pinch)); */ return true;
}
void TabletApplication::swipeTriggered(QSwipeGesture *gesture)
{if (gesture->state() == Qt::GestureFinished) { if (gesture->horizontalDirection() == QSwipeGesture::Left || gesture->verticalDirection() == QSwipeGesture::Up) { main_window->showPreviousWeek(); } else { main_window->showNextWeek(); } main_window->update(); }
}
Thank you for your help

i apologize. I assumed you are using QML.
For QtWidgets you need to callQWidget::grabGesture()
