[Interest] Displaying Help from QHelpEngine through QWebEngine

[Mike Jackson]

I am attempting to use the QHelp* classes to allow our users to search 
our help files (html based) using the same mechanisms as those used with 
QAssistant. So far I have hacked together the major pieces and hooked 
everything up. I am able to manually generate a .qhc file from all of 
our html and image sources. I got so far as to enter a search string and 
have the relevant documents appear in the results widget. Now when I 
click on a link I would like to actually display the help. Currently we 
use QWebEngineView on Qt 5.5.1 because QWebKit was being deprecated. I 
am pretty sure the issue as to why nothing is displayed is because I get 
a URL like the following:


"qthelp://bluequartzsoftware.net.dream3d.1.0/DREAM3D/addorientationnoise.html"


and QWebEngine probably has no idea what to do with that URL scheme. I 
have looked around the internet using Google and while other people are 
asking this same question there are no actual answers. About the only 
possibility seems to get the file contents from the HelpEngine along 
with any CSS and Image assets, write all of those to a temp location on 
the filesystem, then load the URL from the temp location? There must be 
an easier way that I am just missing.


Any help is greatly appreciated.
