[Qgis-user] SVG markers with data defined override

[McDonaldR]

Hi List,

I've been asked to help create a QGIS project for creating layouts of temporary road signage. I have a folder of SVG files and a layer of points with the appropriate SVG file name against each point.  Using the data defined override I can display the correct sign for each point on the map.  However, there is an issue with displaying the correct SVG in the Layers Panel and the Layout legend - there is only a question mark against each sign category.

This same issue has been raised by someone else on Stackexchange here https://gis.stackexchange.com/questions/300005/question-marks-in-qgis-layer-panel-when-using-svg-markers-defined-with-da?rq=1

It was also raised as an issue back in February 2015 (https://issues.qgis.org/issues/12267 and linked to https://issues.qgis.org/issues/11491 )

Is it an easy fix? What's required? Could we sponsor a fix?

Thanks

Ross
