First: document your code. This will allow Qt Creator (is that your IDE?) to recognize documentation comments and will display them on hover automatically.

If you want to install documentation like Qt has it (F1 takes you to full class documentation), you need to generate .qch help file from your project, then manually install it to Qt Creator.

A good documentation tool which will help you do all that is doxygen.
