Load event in qdialog?

Message 1 in thread

Hello everyone,

    I'm relatively new to QT, but I have years of C++ VC++ VC# under my belt.  One quick question.  Is there a Load event or a load slot for a qdialog object that I can use to execute another thread/code after the dialog itself has rendered itself onto the screen?  I'm trying to make my application launch, and if the settings file isn't found, for a block of code to execute to prompt the user for setting data.  Because this involves webcam feed, I need to see the complete rendered application first.  Any help?

Thanks all.

You can use QTimer::singleShot() with timeout value 0. That will be called 
whenever your application reaches the eventloop - in other words - nothing 
else is to do ;-) This is also documented in the QTimer-docs IIRC.

Or could you possibly extend the dialog's ::showEvent method?<br>

Susan,

Please dont use html only formatted mails when posting to a public
mailing list. This makes it unnecessary hard to read your postings for
some of us.

Best regards,

Andre

Hadn't realized it was an issue, my apologies.  Notice I've switched. 
Thunderbird (the email tool I use) does html by default...
