Qt Style Sheets and Custom Painting Example

alom

Hi,
I'm trying to follow the c++ example of assigning a qproperty on a custom widget to be update via stylesheet in a paint event.

https://wiki.qt.io/Qt_Style_Sheets_and_Custom_Painting_Example

I dont get any errors, but I also am not getting my stylesheet color. Is QtCore.Property the same as Q_PROPERTY in the example?

I could only find futher readings on the QtCore.Property here:
https://wiki.qt.io/Qt_for_Python_UsingQtProperties

The expected behavior from the code below is to have to button change to Red (defined in stylesheet) when clicked.

import sys
import os
from PySide2 import QtWidgets, QtGui, QtCore
from PySide2.QtCore import Qt


class CustomWidget(QtWidgets.QPushButton):

    def __init__(self, *args, **kwargs):
        super(CustomWidget, self).__init__(*args, **kwargs)
        self.setCheckable(True)
        self._shmee = None

    def get_shmee(self):
        print('GET')
        return self._shmee

    def set_shmee(self, shmee):
        print(f'SET: {shmee}')
        self._shmee = shmee

    def paintEvent(self, event):
        painter = QtGui.QPainter(self)

        width_full = painter.device().width()
        height_full = painter.device().height()

        brush = QtGui.QBrush()

        brush.setStyle(Qt.SolidPattern)

        if self.isChecked():
            brush.setColor(self.get_shmee())
        else:
            brush.setColor(QtGui.QColor(10, 10, 250))

        rect = QtCore.QRect(0, 0, width_full, height_full)
        painter.fillRect(rect, brush)

        painter.end()

    def mousePressEvent(self, event):
        self.setChecked(not self.isChecked())

    shmee = QtCore.Property(QtGui.QColor, get_shmee, set_shmee)


if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)

    custom_style = CustomWidget()

    script_dir = os.path.dirname(__file__)
    stylesheet_path = 'style.css'

    with open(os.path.join(script_dir, stylesheet_path)) as sty:
        custom_style.setStyleSheet(sty.read())

    custom_style.show()

    rec = app.exec_()
    sys.exit(rec)

style.css file :

CustomWidget {
    qproperty-shmee: rgb(250, 10, 10);
}

Ha!
... I was missing a comma in my stylesheet :P

qproperty-shmee: rgb(20, 100, 100);
