Python PyQt5 创建布局

Question

I'm trying to create a layout with pyqt5, but i cannot do it. There are so many error. Why i am getting so many errors.

Answer 1

autoFillBackground() takes no arguments, and MainWindow will not assume the palette of it's central widget unless you explicitly set it. Also, this has nothing to do with a layout.

import sys
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *

class Color(QWidget):

    def __init__(self, color):
        super().__init__()
        self.autoFillBackground()
        palette = self.palette()
        palette.setColor(QPalette.Window, QColor(color))
        self.setPalette(palette)

class MainWindow(QMainWindow):

    def __init__(self):
        super().__init__()
        widget = Color('Blue')
        self.setCentralWidget(widget)
        self.setPalette(widget.palette())


if __name__ == '__main__':
    app = QApplication(sys.argv)
    win = MainWindow()
    win.show()
    sys.exit(app.exec_())
