qt.pointer.dispatch touch errors

[syr123]

Hi there!

I've just finally ported my app from Python 2.7 and Pyside2 to Monterey 12.2, Python version: 3.9.5, PySide6 version: 6.3.0

When I use my Macbook Pro trackpad and hover and and out of a QGraphicsView, which is the child of QWidget, I seemingly spontaneously get these two messages:

qt.pointer.dispatch: delivering touch release to same window QWindow(0x0) not QWidgetWindow(0x600003f7a7c0, name="ClipManagerUiClassWindow")

and

qt.pointer.dispatch: skipping QEventPoint(id=1 ts=0 pos=0,0 scn=427.623,393.774 gbl=427.623,393.774 Released ellipse=(1x1 ∡ 0) vel=0,0 press=-427.623,-393.774 last=-427.623,-393.774 Δ 427.623,393.774) : no target window

Sorry I don't have more detail to provide, I'm at a loss for what's causing this. Happy to provide any other context that would help explain what's going on.

Are there any ways to get more info on what's triggering this for debugging?

Thanks for any leads!

Hi,

Are you able to reproduce that with a minimal script ?

Hi,

today, I've got the same messages as @syr123 when using PySide6 and PyQtGraph to plot some data. The warning messages occur when using the pyqtgraph.PlotWidget. However, they also appear when using QGraphicsView as in the this minimal example:

from PySide6 import QtWidgets


class MainWindow(QtWidgets.QMainWindow):

    def __init__(self):
        super().__init__()

        self.myPlot = QtWidgets.QGraphicsView()
        self.setCentralWidget(self.myPlot)


if __name__ == '__main__':
    app = QtWidgets.QApplication()
    w = MainWindow()
    w.show()
    app.exec()

The app shows an empty graphics view, as expected. Hovering the mouse over the QGraphicsView widget leads repeatedly to the following two messages:

qt.pointer.dispatch: delivering touch release to same window QWindow(0x0) not QWidgetWindow(0x600000e02ca0, name="MainWindowClassWindow")
qt.pointer.dispatch: skipping QEventPoint(id=2 ts=0 pos=0,0 scn=494.183,356.313 gbl=494.183,356.313 Released ellipse=(1x1 ∡ 0) vel=0,0 press=-494.183,-356.313 last=-494.183,-356.313 Δ 494.183,356.313) : no target window

qt.pointer.dispatch: delivering touch release to same window QWindow(0x0) not QWidgetWindow(0x600000e02ca0, name="MainWindowClassWindow")

...

I'm using Python 3.10.5 with PySide6 ver. 6.3.1 on a MacBook Pro 13 2018 with macOS 12.4.

Unfortunately, I'm just about to switch from using matplotlib to the Qt Framework for plotting data. So, I don't know whether the problem has existed before updating from a previous PyQt and Python version.

Any help or workaround is highly appreciated. Thanks!

After testing, it seems to be something new that comes with PySide 6.3.1, 6.3.0 does not trigger this.

You should check the but report system to see if it's something known, if not please open a new ticket with your example script and the details of your machine.
