复制代码 代码如下:
import sys
from PyQt4 import QtGui, QtCore
class Window( QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
self.setWindowTitle(\’hello\’)
self.resize(800,500)
menubar = self.menuBar()
self.file = menubar.addMenu(\’&file\’)
open = self.file.addAction(\’open\’)
self.connect(open,QtCore.SIGNAL(\’triggered()\’),self.OnOpen)
save =self.file.addAction(\’save\’)
self.connect(save,QtCore.SIGNAL(\’triggered()\’),self.OnSave)
self.file.addSeparator()
close = self.file.addAction(\’close\’)
self.connect(close,QtCore.SIGNAL(\’triggered()\’),self.OnClose)
self.label = QtGui.QLabel(\’this is a google text\’)
self.label.setAlignment(QtCore.Qt.AlignCenter)
self.setCentralWidget(self.label)
def OnOpen(self):
self.label.setText(\’open\’)
def OnClose(self):
self.close()
def OnSave( self):
self.label.setText(\’save\’)
def contextMenuEvent(self,event):
self.file.exec_( event.globalPos())
app =QtGui.QApplication(sys.argv)
win = Window()
win.show()
app.exec_()
