[Qt-interest] QBasicTimer in a QApplication?

[John Weeks]

My application has need of periodic execution, so I learned about  
QTimers. I made a QTimer as a member of my QApplication subclass and  
connected it to a slot. Works fine.

Then I read about QBasicTimer, and read that it is light-weight.  
Eventually, this is an application that needs the best possible  
performance, so that sounds good. I wired up a QBasicTimer in my  
QApplication subclass and it didn't work. I followed the Wiggly  
example to write my event handler.

I moved my QBasicTimer to one of my widgets instead. Now it works!

Is there a problem with using QBasicTimer with a QApplication as the  
object that handles the events?

I'm doing this on Macintosh with Qt 4.6.3. Haven't had a chance yet to  
try this on Windows.
