[Qgis-user] QGIS Actions and relative path

[Andreas Neumann]

 You could probably do this with python. I am not entirely sure if it 
 works, but there are python actions. The python action gets a reference 
 to the feature - maybe - if you can access the project file from python, 
 there is a QgsProject::readPath 
 (http://doc.qgis.org/head/classQgsProject.html#cfdc9943dcba296540309f89e93a9f60). 
 This way you can detect the absolute path of the project file and build 
 your path as you like.

 But you are right, it would be convenient if file reference could be 
 stored relative to the project file.

 Maybe Jürgen has some idea.
