[Qt-creator] Migrating Qt Assistant bookmarks to new installed Qt version

[Ernst Huber]

This is not directly related to Creator, but since most of the Creator 
users will face the same problem when migrating to a new Creator version 
I hope finding an answer through this mailing list.

My problem is quite simple: after installation of a new Qt version with 
all the tools, the new Assistant installation doesn’t remember my 
bookmarks collected with Assistant of the previous version. The 
assistant manual explains how to use different help collections from the 
command line with this parameter:

-collectionFile <file.qhc> // Uses the specified collection file instead 
of the default one.

And it works when providing the help collection of the previous version. 
I tested Qt Assistant with Qt 4.5.1 using the help collection of Qt 
Assistant with Qt 4.5.0 like this:

C:\Dokumente und Einstellungen\Username>assistant -collectionFile 
"C:\Dokumente und Einstellungen\Username\Lokale 
Einstellungen\Anwendungsdaten\Trolltech\Assistant\qthelpcollection_4.5.0.qhc" 


But sooner or later I guess there will be troubles because with this 
approach I’m bound to the Qt help of a specific version (thus not 
allowing me to remove that older Qt version). Therefore I ask if there 
is a better way to keep my bookmarks while at the same time being able 
to always use the Qt help of the newest installed Qt version on my system.

Thanks for any reply.
