Application "Not Responding"
I developed one application software in qt.its working fine but sometimes when process is going on and you click somewhere then application "Not Responding " message will display on top and application software hang after few min is working fine.
How to remove this hang problem or "Not Responding " issue ?
Im using windows 7 (32bit) ,Qt Creator 4.6.0 Based on Qt 5.10.1 (MSVC 2015, 32 bit).
Make sure your main UI event loop is always "active" and responding. In other words, somewhere you are doing something time-insensitive in your code. You need to change that so that either it uses signals & slots so it does not block, and/or hand off the computation to a non-UI thread you create. or if you have to be "naughty", you might have to call
QCoreApplication::processEvents()explicitly, but try not to do that...
