Description

macos 10.13.5, qgis 3.2,

Everything works fine when I have a file path as a location for the image but when I put a url the image does not get loaded and I get no error messages.

I erported this on stackgis a week ago and got no responses:

I'm really not sure eVis ever supported URLs. Do they work on QGIS LTR (2.18)?

https://biodiversityinformatics.amnh.org/open_source/evis/documentation.php says:

"The location and name of the photograph can be stored using an absolute or relative path or a URL if the photograph is available on a web server. Examples of the different approaches are listed below...."

I have just checked the evisgenericeventbrowsergui.cpp source on GitHub:

if ( mEventImagePath.startsWith( QLatin1String( "http://" ), Qt::CaseInsensitive ) )
   {
imageDisplayArea->displayUrlImage( mEventImagePath );
}
else {
imageDisplayArea->displayImage( mEventImagePath );
}

If it was python I would do the diagnostics myself but I am not really set up to do stuff with C++ :(

Can plugins like this be build independent of qgis as the name suggests. If so I might have a try.
I no longer have a 2.18 instance so I don't know.

if you can prove it worked on 2.18 then this will get a higher priority. Can't you install 2.18 and try?

done and no it behaves the same in 2.18 :( Clearly no one is using this feature which surprises me.

I repeat my question about building the plugin on its own (see previous comment). I am an experienced developer and I am happy to have a look at debugging it but only if I can do it without building the whole of QGIS! I am working on a Mac with XCode.

compiling the whole thing is not hard nor takes long, at least on linux.
