Hi
Ok - While the test program generates loads of output, unfortunately its still not recognising a swipe... I did note that your example is using PyQT6, I hadn't mentioned that I'm using PySide6 - however, I believe that they should be compatible.

I don't expect a difference either. The first version was written in C++, and no PyQt-specific changes were required to port it.

Meanwhile - I opened the program, did a very quick swipe right to left, and here's the output:

qt.widgets.gestures: QGestureManager:Recognizer: maybe gesture:  QSwipeGesture(state=NoGesture,horizontalDirection=Right,verticalDirection=NoDirection,swipeAngle=0) QTouchEvent(TouchBegin device: "" states: Pressed, 1 points: QList(QEventPoint(id=0 ts=92554578 pos=429.5,265 scn=829.5,481 gbl=829.5,481 Pressed pressure=0.5 ellipse=(65.5x84.5 ? 0) vel=0,0 press=429.5,265 last=429.5,265 ? 0,0)))

The swipe gesture recognizer starts out by indicating that the first two events might be related to a swipe, so we know that the right type of input is being received. Changing touch input settings is apparently not warranted. It then switches to ignoring the events, before eventually declaring "not gesture". Looking at QSwipeGestureRecognizer::recognize , there's a state change that occurs when 3 touch points are present.

        else if (ev->points().size() == 3) {
            d->state = QSwipeGesturePrivate::ThreePointsReached;

The attempted swipe in the logs above appears to be limited to a single touch point. Does a 3 finger swipe generate substantially different output?

As I'm only interested in swipes, I removed the other gesture types from the list, so I peared down the program to:

from PySide6.QtWidgets import QApplication, QWidget
from PySide6.QtCore import QEvent, QLoggingCategory, Qt

class Widget(QWidget):
    def event(self, e: QEvent) -> bool:
        if QEvent.Type.Gesture == e.type():
            print(f"Gesture delivered: {e.gestures()}")
        return super().event(e)

app = QApplication([])
QLoggingCategory.setFilterRules("qt.widgets.gestures=true")
w = Widget()


w.grabGesture(Qt.GestureType.SwipeGesture)
w.show()
app.exec()

As per the end of each statement, I suspect touches are being turned into mouse events (the end of each line says 'source=MouseEventSynthesizedBySystem')

Not sure why its doing that... or if there's a way to turn it off

According to https://doc.qt.io/qtforpython-6/PySide6/QtGui/QTouchEvent.html:

To receive touch events, widgets have to have the Qt::WA_AcceptTouchEvents attribute set and graphics items need to have the acceptTouchEvents attribute set to true.

However, adding:
w = Widget()
w.setAttribute(Qt.WA_AcceptTouchEvents, True)

Appears to have no effect...

Any thoughts?

(I'm running on windows 11, surface pro 9 - developing under VS Code.)

I've ended up installing event filter and capturing the mousebutton or touchevents and position start/end to work out the swipe...

The intended usage is to register a gesture recognizer.

The annoying thing is that when I update the html, I have to re-install the eventfilter otherwise it won't respond to touch events...

How are you installing the event filter?

What operating system, windowing system, and hardware are you using? A look at the source for QGestureManager shows different recognizers for macOS based platforms versus the default case.

Also, are you able to trigger any other gestures?

Voluminous gesture debugging:

from PyQt6.QtWidgets import QApplication, QWidget
from PyQt6.QtCore import QEvent, QLoggingCategory, Qt

class Widget(QWidget):
    def event(self, e: QEvent) -> bool:
        if QEvent.Type.Gesture == e.type():
            print(f"Gesture delivered: {e.gestures()}")
        return super().event(e)

app = QApplication([])
QLoggingCategory.setFilterRules("qt.widgets.gestures=true")
w = Widget()

for gesture in (Qt.GestureType.TapGesture,
                Qt.GestureType.TapAndHoldGesture,
                Qt.GestureType.PanGesture,
                Qt.GestureType.PinchGesture,
                Qt.GestureType.SwipeGesture):
    w.grabGesture(gesture)
w.show()
app.exec()

On a mac, I have only been able to cause a TapAndHoldGesture with a mouse. With a touch pad, PanGesture is also easily triggered. I haven't had any luck so far with PinchGesture or SwipeGesture. The gesture manager source linked above tells me not to expect TapGesture.

The annoying thing is that when I update the html, I have to re-install the eventfilter otherwise it won't respond to touch events... weird...
