Drawing example rendering wrong on pyside6

[nstelter-slac]

Describe the bug

example file in question is examples/drawing/drawing_demo.ui

it should look like this (how it looks on pyqt5 atm):

but on pyside6 looks like this:

(penStyle is wrong pyside6 perhaps??)

i think this is related to qt property declarations not working on pyside6 b/c they are not implemented in the new way (fixing #1275 might fix).

but my memory on exactly why i think this is the cause is fuzzy, i can investigate more later if needed

Steps to reproduce

1. create conda env with python 3.13 and pyside6:

  $ conda create -n pydm-environment-pyside python pip numpy scipy six psutil pyqtgraph pydm -c conda-forge
  $ source activate pydm-environment
  $ pip install PySide6 # or can install with conda in earlier cmd

2. activate conda pyside6 env and export QT_API=pyside6

3. run the example with pydm examples/drawing/drawing_demo.ui, and can also then activate your pyqt5 env and run the example there to compare.

Expected behavior

examples/drawing/drawing_demo.ui renders the same on both pyqt5 and pyside6

You are correct with your thoughts that it is related to the penStyle not being a valid PySide6 property, so #1275 should fix it.

I tried adding this, and that was enough to get it to render correctly with PySide6

    def readPenStyle(self):
        return self._pen_style

    def setPenStyle(self, new_style):
        if type(new_style) == int:
            new_style = Qt.PenStyle(new_style)
        if self._alarm_state == PyDMWidget.ALARM_NONE:
            self._original_pen_style = new_style
        if new_style != self._pen_style:
            self._pen_style = new_style
            self._pen.setStyle(new_style)
            self.update()

    penStyle = Property(int, readPenStyle, setPenStyle)
