问题描述
我正在为我的应用程序收集使用情况统计信息,其中包括每个会话的持续时间.但是,我似乎无法保存此信息,因为我尝试过的信号中没有一个实际上成功调用了我的 report_session 函数.
I am collecting usage stats for my applications which include how much each session lasts. However, I can't seem to be able to save this information because None Of the signals I tried yet actually succeeds to call my report_session function.
这是我已经尝试过的信号:
This are the signals I have already tried:
- lastWindowClosed()
- aboutToQuit()
- 销毁()
要么这些信号永远不会发出,要么应用程序在此之后的寿命不够长,无法运行其他任何东西.这是我的主要内容:
Either these signals never get emitted or the application does not live long enough after that to run anything else. Here is my main:
app = QtGui.QApplication(sys.argv)
ui = MainWindow()
ui.app = app
QtCore.QObject.connect(ui, QtCore.SIGNAL("destroyed()"), ui.report_session)
ui.show()
logger.info('Started!')
splash.finish(ui)
sys.exit(app.exec_())
推荐答案
Found 这个答案 涉及重载 closeEvent().
Found this answer which involves overloading closeEvent().
它非常适合我.
