[Qgis-user] Using Values from selected object in printcomposer

[Andreas Neumann]

Hi Martin,

Yes - you can use "Atlas print" for that. If you add an Atlas in the 
print composer for the concerned layer, you get an automatic Atlas 
action ("Set as Atlas feature for Atlas"). You can select an object in 
the map or in the attribute table and open the corresponding feature in 
the Atlas. In the Atlas you can use any attribute of the atlas feature 
and use it in graphical properties, label content, etc.

Have a look in the manual: 
http://docs.qgis.org/2.14/en/docs/user_manual/print_composer/create_output.html#generate-an-atlas 
to get an idea how you can specify the "Atlas" in print composer. You 
can find the "Actions tool" in the toolbar next to the "Identify 
Features" tool in the "Attributes" toolbar. Once an atlas is configured 
on the selected layer, the "Set as Atlas feature for Atlas" is 
automatically added, and you can use this tool to select features on the 
map. After clicking on the object, print composer will open and use the 
selected feature.

Let me know if you need help on that or can find it out yourself. I am 
happy to help if you are stuck. The Atlas is really powerful. There is a 
lot of possibilities, including dynamic styling, dynamic HTML content, 
calling web services, tables, all based on the selected atlas feature.
