QCH help files

**Koas** · 10th February 2009, 13:11

Hi all! I'm trying to implement some inline help in a few dialogs of an app. I've compiled a .qch file with the user manual, and my question is this:

How can I launch (not with QtAssistant, with a TextBrowser or some other widget) a file of my compiled .qch file when the user clicks the ? icon in a dialog?

The Qt documentation is quite poor in this topic... I'm not sure how to catch when the user clicks on the ? icon and how to show the help.

Any help would be really appreciated!

See Using QHelpEngine API and QHelpContentWidget. As for the "?" icon, this is carried by QHelpEvent.

qch files are regular sqlite3 databases.

Hi Koas
I have bought a book on CD ROM, it has exe and dmg file formats. After I installed it on my pc, it installed some dill files and data.qch file in the program files. I am able to open the book on the pc, read, search etc. How can I extract the text from the data.qch file, can you please advice a software to buy? Its an important book for my exam and I want to convert the text into into a pdb format or chm format to study on my iPhone.
thank you
