Linked png in QtHelp file
-
I'll have to back off my previous statement. The 5.5.1 I built has an Assistant binary which - according to the About - uses TextBrowser. So, I have not demonstrated that WebKit won't display png's correctly. What arguments do I add to the configure to insure Assistant builds with WebKit?
How do I attach an image to a post?
-
What OS are you on ?
-
After a long set of sessions building Qt 5.5.1 with arguments I thought might link in WebKit, I arrived at a 5.5.1 assistant which its About dialog says still uses TextBrowser. Lots of Googling with no results, so I ask here: do you know what arguments to ./configure insure Assistant uses WebKit?
-
What parameters are you passing to configure when you build Qt ?

@mrjj My efforts to prove that the WebKit-to-TextBrowser change is what has removed the ability to directly anchor PNG files in Assistant-based help has just taken too long and not produced reliable results. Similarly, my efforts to get acknowledgement (here or in various Googled sites) that this is a known problem have been fruitless thus far.
I wrote a script that produces a thin HTML wrapper to each PNG I wish to anchor. Writing that script, applying it tor 17 anchored image files and modifying the appropriate href= values in 28 individual HTML components took much less time than I'd spent so far trying to find a Qt fix or appropriate general modification in our code.
Thank you, mrjj, for the knowledge about TextBrowser. I will likely be marking this topic as "Solved" shortly unless there are any further relevant insights brought forward.

Thank you for trying to verify. I had no luck either finding info regarding loss of
this feature or similar. I remembered it - as suddenly the help looked .. different.Could you for future reference paste a "used to work" html sample and
how it should look to do the correct thing with text browser? -
@mrjj
This used to work:
<a href=“images/vhw_enh_groups.png”>vHW Enhanced Groups</a>
Now I must use:
<a href=“vhw_enh_groups.img.html”>vHW Enhanced Groups</a>
where the *.img.html file is just a rudimentary header and footer of HTML around:
<img src="images/vhw_enh_groups.png" alt="van Holde -Weischet groups dialog"/> -
I tried one more time to build a 5.5.1 Qt where Assistant (for custom help) uses WebKit. I added "-D BROWSER_QTWEBKIT" as a configure argument. But I encountered numerous compile and link problems and never got a new Assistant built.
So, I've decided to spend no more time on this. The topic is "Solved" in the sense that it is assumed that TextBrowser will never properly handle anchored png files. In our applications help files, all anchored png have been replaced with img.html files that are thin HTML wrappers around an embedded image.
Thanks again. mrjj, for your help.

Hi
Building webkit is often a pain. Multiple dependencies. But you gave it a good shot :)
I agree that the wrapper you made
seems the best way forward as having to compile own version
of Assistant is not optimal.
Thank you for reporting back on this matter. It will come up again :)
