使用setStyleSheet设置窗口背景图片

import sys

from PyQt5.QtCore import *
from PyQt5.QtWidgets import *if __name__ == "__main__":app = QApplication(sys.argv)win = QMainWindow()win.setWindowTitle("界面背景图片设置")win.resize(350, 250)win.setObjectName("MainWindow")win.setStyleSheet("#MainWindow{border-image:url(./pyqt5/python.jpg)}")win.show()sys.exit(app.exec_())

使用setStyleSheet设置窗口背景颜色

import sys
from PyQt5.QtGui import *

from PyQt5.QtWidgets import *if __name__ == "__main__":app = QApplication(sys.argv)win = QMainWindow()win.setWindowTitle("界面背景图片设置")win.resize(350, 250)win.setObjectName("MainWindow")win.setStyleSheet("#MainWindow{background-color:yellow}")win.show()sys.exit(app.exec_())

使用QPalette设置窗口背景颜色

import sys
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *if __name__ == "__main__":app = QApplication(sys.argv)win = QMainWindow()win.setWindowTitle("QPalette调色板设置背景颜色")win.resize(350, 150)palette = QPalette()palette.setColor(QPalette.Background, Qt.red)win.setPalette(palette)win.show()sys.exit(app.exec_())

使用QPalette设置窗口背景图片

import sys

from PyQt5.QtCore import *
from PyQt5.QtWidgets import *if __name__ == "__main__":app = QApplication(sys.argv)win = QMainWindow()win.setWindowTitle("QPalette设置背景图片")palette = QPalette()palette.setBrush(QPalette.Background, QBrush(QPixmap("./pyqt5/python.jpg")))win.setPalette(palette)win.resize(800, 600)win.show()sys.exit(app.exec_())

使用paintEvent设置窗口背景颜色

import sys
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *class WinForm(QWidget):def __init__(self, parent=None):super(WinForm, self).__init__(parent)self.setWindowTitle("paintEvent设置背景色")def paintEvent(self, event):painter = QPainter(self)painter.setBrush(Qt.blue)painter.drawRect(self.rect())if __name__ == "__main__":app = QApplication(sys.argv)win = WinForm()win.show()sys.exit(app.exec_())

使用paintEvent设置窗口背景图片

import sys
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *class WinForm(QWidget):def __init__(self, parent=None):super(WinForm, self).__init__(parent)self.setWindowTitle("paintEvent设置背景图片")def paintEvent(self, event):painter = QPainter(self)pixmap = QPixmap("./pyqt5/images/screen1.jpg")painter.drawPixmap(self.rect(), pixmap)if __name__ == "__main__":app = QApplication(sys.argv)win = WinForm()win.show()sys.exit(app.exec_())
