问题描述
我正在构建一个Qt Symbian项目，我想向用户显示一条通知，该通知应在几秒钟后自动关闭.我已经看到诺基亚在用户界面中经常使用此功能.
I'm building a Qt Symbian Project and I want to show a notification for the user that should auto close after some seconds. I have seen that Nokia uses this a lot in their ui.
现在我正在使用下面的代码，以便用户可以关闭QMessageBox，但是如果可以在1或2秒后自动关闭QMessageBox，我希望这样做.如何使用Qt做到这一点?
Right now I'm using the code below so that the user can close the QMessageBox but I would like it if it was possible to auto close the QMessageBox after 1 or 2 seconds. How can I do this using Qt?
QMessageBox msgBox;
msgBox.setText("Hello!");
msgBox.setIcon(QMessageBox::Information);
msgBox.setStandardButtons(QMessageBox::Ok);
msgBox.exec();
推荐答案
我建议将QMessageBox子类化，以添加自己想要的行为...
I would suggest to subclass QMessageBox to add your own desired behavior...
启用自动关闭选项后，添加setAutoClose(bool)和setAutoCloseTimeout(int)之类的方法并在showEvent上触发QTimer会很有趣！
It would be interesting to add methods like setAutoClose(bool) and setAutoCloseTimeout(int) and trigger a QTimer on showEvent when the AutoClose option is enabled !
这样，您甚至可以更改QMessageBox的外观，并显示此框将在XXX秒后自动关闭..."或进度条等文字.
This way, you could even alter the apparence of your QMessageBox and had a text saying "This box will close automatically in XXX seconds..." or a progress bar, etc...
