I am new to Python learning to code again after a long break. So forgive if this is trivial (which it almost certainly is).
I am trying to create a subclass of QWidget to make it easier to set a background colour (and other stuff in the future of course).
I have two examples, one works and the other does not. I would like to 'fix' the one that does not.
The task is to create a window with a red background.
(Note. I am english, hence the use of colour not color in my customization)
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *
import sys
class MainWindow(QMainWindow):
def __init__(self, *args, **kwargs):
super(MainWindow, self).__init__(*args, **kwargs)
cw1 = QWidget()
cw1.setAutoFillBackground(True)
cw1.setStyleSheet("background-color: Red;")
self.setCentralWidget(cw1)
app = QApplication(sys.argv)
window = MainWindow()
window.show()
app.exec_()
In this version I am subclassing QWidget to allow the colour parameter
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *
import sys
class ColourW(QWidget):
def __init__(self, colour, *args, **kwargs):
super(ColourW, self).__init__(*args, **kwargs)
self.setAutoFillBackground(True)
self.setStyleSheet("background-color: {colour};")
class MainWindow(QMainWindow):
def __init__(self, *args, **kwargs):
super(MainWindow, self).__init__(*args, **kwargs)
cw1 = ColourW('red')
self.setCentralWidget(cw1)
app = QApplication(sys.argv)
window = MainWindow()
window.show()
app.exec_()
Any help much appreciated.
