When generating a modified Qt Help file and viewing it using the Qt assistant.exe software, the latest changes are not displayed.
This is a known bug of the Qt assistant.exe software which creates a cache version of the .qhc help file. The only solution is to manually delete this cache as follows:
- Note the name of the .qhc file that you are creating. E.g. sample.qhc
- Hit the Windows+R keyboard shortcut to show the "Run" dialog
- Type the path of the Qt Help assistant cache folder. Usually this is: %USERPROFILE%\AppData\Local\QtProject\Assistant
- Delete the .qhc file and folder with the same name of your generated documentation project. E.g. sample.qhc and .sample
