[FIXED] pyside QPushButton toggle background color

Issue

When I have a QPushButton that is pressed with the toggle option. How do I set the background color of the button to be another color other than black? This code attempts to use StyleSheets to do so, but it remains black.

    light_label = QtWidgets.QPushButton(light)
    light_label.setCheckable(True)            
    light_label.toggled.connect(partial(self.light_label_event, light))
    light_label.setStyleSheet('QPushButton::checked{background:rgb(255, 0, 0); }')

Solution

You have to use the pseudo-state checked:

import sys
from PySide import QtGui


if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    button = QtGui.QPushButton("Hello world")
    button.setCheckable(True)
    button.setStyleSheet("""
        QPushButton {background:rgb(65,66,66); color: white;} 
        QPushButton::checked{background:rgb(255, 0, 0); color: white;}
    """)
    button.show()
    sys.exit(app.exec_())
