menubar=self.menuBar()
filemune=menubar.addMenu('$File')
filemune.addAction(openfile)

self.setWindowTitle('FIELdialog')
self.show()
defshowDialog(self):
fname=QFileDialog.getOpenFileName(self,'openfile','/')
iffname[0]:

withf:
data=f.read()

except:
self.textEdit.setText("打开文件失败,可能是文件内型错误")
if__name__=="__main__":
app=QApplication(sys.argv)
