How to change QPushButton backround color without using CSS

Question

So far I am only able to customize the button text color:

button = QtGui.QPushButton()
palette = QtGui.QPalette(button.palette())
palette.setColor(QtGui.QPalette.ButtonText, QtGui.QColor('blue'))
button.setPalette(palette)

But how to change the button background color?

None of this will change the button background color:

    palette.setColor(QtGui.QPalette.Foreground, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.Button, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.Light, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.Midlight, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.Dark, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.Mid, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.Text, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.BrightText, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.ButtonText, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.Base, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.Background, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.Midlight, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.Shadow, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.Highlight, QtGui.QColor('red'))
    palette.setColor(QtGui.QPalette.HighlightedText, QtGui.QColor('red'))

how about this? : self.pushButton.setStyleSheet("background-color: red") — Kasravnd

This is CSS. The question is how to do the same without using it. — alphanumeric

looks like pallet.setColorGroup? (pyqt.sourceforge.net/Docs/PyQt4/qpalette.html#setColorGroup) — Gerrat

Not sure...there's also an old thread on a mailing list that gives an example of setting a button's background color: riverbankcomputing.com/pipermail/pyqt/2006-February/012279.html — Gerrat

you need to set the right "role" and append "setAutoFillBackground()":

button = QtGui.QPushButton()
palette = self.button.palette()
role = self.button.backgroundRole() #choose whatever you like
palette.setColor(role, QColor('red'))
button.setPalette(palette)
self.button.setAutoFillBackground(True)

You may also need to apply setFlat() depending on the theme (I did!). See stackoverflow.com/questions/21685414/… answers and comments

Some QStyles, specifically Windows Vista, takes certain aspects of the gui from the operating system, so you can't change them directly with a QPalette.

You can query available QStyles with

QStyleFactory.keys()

['windowsvista', 'Windows', 'Fusion']

Change the qstyle to some other Style, with

app.setStyle("Fusion")

Now, it will respect a QPalette's

QPalette.Button
