Offline Help on all platforms

[Andreas Preikschat]

Hello,

Currently we only have an offline help file on windows, this should be changed. We need to have an offline help file (accessible from the Help menu) on all platforms. This can be achieved by using QtHelp.

Cheers

Let's see if we'll manage to get this implemented before feature freeze.

Windows doesn't need to use the QtHelp, it has the HTML Help system (which we are already building).

As for OS X, we'll need to work out how to bundle the QtHelp browser.

Ok for Fedora but have bug with viewer.

[Raoul Snyman (raoul-snyman)]

I noticed that Eric4 has an eric4help.qhc file in it's ~/.eric4 directory. Not sure how we'd handle updates, but that's an option.

[Tim Bentley (trb143)]

Looked at eric on fedora and the source,qch file is in /usr/lib/python2.7/site-packages/eric4/Documentation/Help.

The files is a sqlite database and seems to have rows in the index tables. The OpenLP.qch table is empty.

I get a lovely segfault when I try to view the helpfile...
