No spontaneous showEvent generated when window is opened ?!

[yesint]

Dear all,
I'm trying to scroll very large list to specific position when main window is opened. As far as I understand for this I need to add code to spontaneous showEvent because this is one executed just after window is opened.
Here is the code:



void MainWindow::showEvent(QShowEvent *event){
if(event->spontaneous()){
qDebug()<<"after";
} else qDebug()<<"before";
}


This always prints "before" - there is no spontaneous event at all! It seems that i missed something simple. Any help is deeply appreciated!

Bump! No ideas?

I doubt show events are ever spontaneous. Show events are generated within your application. Maybe when application is being unminimized a spontaneous show event might occur. Why do you need to react on spontaneous events only?

[yesint]

Well, what I need to do is to scroll a very long list just upon creation of the window. The scrollTo method only works when the window is already shown, so I don't see any other way to do this. If there is some, please give me a hint.

Try re-implementing resizeEvent instead.

[yesint]

No luck. resizeEvent is either not called when the window is shown for the first time or called before showEvent. Anyway scrollTo doesn't work. I'll probably make a new thread for scrollTo functionality.

But why are you checking if the event is spontaneous?
