Qt: how to make help system?

I need to provide some help system for my application. The app mostly works on the computers without any Qt installed. I would like to have some way (tool etc) to create the professionally looking help system. I mean I need to provide the regular help system like most applications have. It should look like regular CHM file (with index, search etc.).

I tried to use QtAssistance class, created .adb file but if I run assistance utility, it doesn't know -profile key so I even cannot check if I did this file properly.

I'm a little bit confused because I could see QtAssista开发者_运维知识库nt and QHelp classes and I don't know which one is more suitable for my purpose.

Thanks a lot

If you do not care for using Microsofts chm-files, then go ahead and use the QtHelp API - if you are using Qt versions 4.4 or newer. The QAssistant API has been superseded by QtHelp starting with version 4.4, so don't start with old or deprecated interfaces. The QAssistant help files will still be readable from a QtHelp based implementation.

If you do need to read chm files, then a chmlib-based approach with a customized QWebBrowser would be suitable, but I don't think that's what you are looking for.
