How to access main loop

[roseicollis]

Hi!
I know there is a loop runing when you make an app in Qt... so my question is... how can I access it?

I want to call a function every second.

Also I want to show an Image 1 second every 5 seconds.

Thank you!

See QTimer. It can be used to repeatedly call a method through Qt's signal/slot mechanism.

Hi,

I already saw a QTimer but wasn't sure if I could use it without problems.

Then you can't access the main loop? How can I make a function and call it every second or every milisecond?

What problems ? QTimer is an essential tool to periodically perform a task.
Define this function as a slot and connect to them QTimer::timeout signal.

Which app are you creating? QTGui application, or QTconsole application?
