[Development] What's This help

[Graham Labdon]

Hi
I am in the process of porting an application from Qt4.8 to Qt5 and have come across the fact that there is no 'Whats This' help for dialogs
This has been reported here
https://bugreports.qt-project.org/browse/QTBUG-32835

However, I need a fix urgently so was looking at the source code to see if I could see what is going on but could not find it.

Does anyone have any hints or clues as to where the code to send the Whats this event is to be found? 

Regards,

Graham Labdon
