Whatsthis for application main window
How can I implement WhatsThis functionality for my applications main window?
I have a simple app with some buttons; I set the whats this text in designer but they dont show when I run the app
use "setWhatsThis()":http://qt-project.org/doc/qt-4.8/qwidget.html#whatsThis-prop on your main window.
Please read [[doc:qwhatsthis]]
