Popup will appear and you select "number". And get the code:
And there will be small window with like 7 modification of "number" methods. If you press F1 you will get Help window saying "No documentation available."
But why? There is like 7 Qt functions and help is giving me nothing. In qt-help functons with same name are usually placed nearby ... so Creator show me just any help for some "number" function! I will find the rest nearby.
And even better ... in this small windows I can select version of method I amd interested in and press F1 to get help for selected method.
