PyQt5笔记 - 状态栏和简单菜单

显示状态栏和菜单

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QAction, qApp
from PyQt5.QtGui import QIcon

class Example(QMainWindow):

    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        exitAct = QAction(QIcon('exit.png'), '&Exit', self) #1
        exitAct.setShortcut('Ctrl+Q')
        exitAct.setStatusTip('Exit Application')
        exitAct.triggered.connect(qApp.quit)

        self.statusBar().showMessage('Ready')

        menubar = self.menuBar()   #2
        fileMenu = menubar.addMenu("&File")
        fileMenu.addAction(exitAct)

        self.setGeometry(300, 300, 250, 150)
        self.setWindowTitle('StatusBar')
        self.show()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())

1. 创建Aciton
2. 菜单加入action
