[FIXED] Painter Shape over QIcon in PySide

Issue

How can I append a painted rectangle to a QIcon. The final returned result has to be a qicon because I'm using this on a control which expects a qicon.

Before:

After:

import os, sys
from PySide import QtCore, QtGui


class Example(QtGui.QWidget):

    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)
        self.resize(600,400)

        self.btn = QtGui.QPushButton()
        self.btn.setFixedSize(128,128)
        icon = QtGui.QIcon('thumb.jpg')
        self.btn.setIconSize(icon.availableSizes()[0])
        self.btn.setIcon(icon)

        lay = QtGui.QVBoxLayout()
        lay.addWidget(self.btn)
        self.setLayout(lay)


def main():
    app = QtGui.QApplication(sys.argv)
    ex = Example()
    ex.show()
    sys.exit(app.exec_())


if __name__ == '__main__':
    main()

Solution

You have to read the image as QPixmap, use QPainter to modify the QPixmap by adding the rectangle and finally use the QPixmap to create the QIcon

import sys

from PySide import QtCore, QtGui


class Example(QtGui.QWidget):
    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)
        self.resize(600,400)

        lay = QtGui.QHBoxLayout(self)

        pixmap = QtGui.QPixmap('thumb.jpg')
        painter = QtGui.QPainter(pixmap)
        painter.fillRect(QtCore.QRect(20, 20, 40, 40), QtGui.QColor("red"))
        painter.end()

        for icon in (QtGui.QIcon('thumb.jpg'), QtGui.QIcon(pixmap)):
            btn = QtGui.QPushButton()
            btn.setFixedSize(128,128)
            btn.setIconSize(icon.availableSizes()[0])
            btn.setIcon(icon)
            lay.addWidget(btn)

def main():
    app = QtGui.QApplication(sys.argv)
    ex = Example()
    ex.show()
    sys.exit(app.exec_())


if __name__ == '__main__':
    main()
