[Qt-interest] measure the time it takes to create and paint a control an all its children

[Niklaus Hersche]

Hi Altan, thanks for answering.

I thought of something more elegant, maybe an event, or overwriting a
method.

Is the underlying platform graphics subsystem aware of the widget (parent
children) the paint calls belong to.

  One alternative:

  If you dive down into the Qt sources, you can definitely
  intercept the place(s) where it calls the underlying
  platform graphics subsystem to do the actual painting
  onto the screen.

  I've definitely done this for QWS, the Qt Window Server
  that runs on Embedded Linux but I'm sure it can be done
  for any platform.

Hello

I have implemented (Qt 4.5.2) a custom widget with a lot child widgets.
I want to measure the time it takes to create and paint the widget and all
its children.
Since the whole process is event driven, I don't know where to stop the
timer.


Has anybody an idea?

Thanks a lot.

Nik
