QThread::Sleep goes to not responding state
Hi guys,
I'm currently using QThread::Sleep yet i have observe the application went to "not responding" state during sleep.Is there a way to prevent this? Is there any option to set the application into halt for several seconds without experiencing not responding? I want that the UI wont be accessible during the specified time frame.
Thanks!

Re: QThread::Sleep goes to not responding state
Where did you use QThread::Sleep in code?
One way to stop UI responding is don;t let the control go back to event loop. (Block/Loop/Sleep in a Slot, and signal the slot as required)
When you know how to do it then you may do it wrong.
When you don't know how to do it then it is not that you may do it wrong but you may not do it right.

Good question!Originally Posted by Santosh Reddy
True, but the problem is the UI not responding so another way to achieve an unresponsive UI is probably not that helpful
Everything that blocks the main thread will lead to an unresponsive UI. The good thing is that the main thread doesn't do anything if doesn't have to, so it will "sleep" by default.

In lieu of sleeping or blocking per se, you might consider simply disabling your interface: highLevelWidget.setEnabled(false). When the "specified time frame" has elapsed, you then simply re-enable the interface using a signal-slot connection.

use a modal dialog.
If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.
