Porting QT 4.8 project to QT5.1 version
sudh last edited by
I have ported QT 4.8 (VC 2010) project to QT 5.7 (VC 2013). I am able to execute the application but facing following issues.
- The operating are very very slow. After click on a button it takes upto 1 minute to respond.
- One QWidget screen does not respond at all. No mouse or key operations are detected.
please see I am using win32 libs and win32 project env but OS is win64.
Any clue what could be wrong?
I think you will need to put the debugger on it
and find out where it uses all this extra time.
Its nearly impossible to just guess at :)

In visual studio 2013 you can go:
DEBUG -> Performance and Diagnostics... -> Performance Wizard -> <start your application>
It has helped me immensely!
