[Qgis-user] Multiple lines label in QGIS 2.0 print composer using wrap on character?

[Carlos López PSIG]

Hello Alexandre and everyone,
You can use "Expresion based label" in label properties...
For instance:

CASE
WHEN "CRLFPOS1" = 0 THEN "TEXT_TOP"
WHEN "CRLFPOS1" > 0 AND "CRLFPOS2" = 0
THEN
substr("TEXT_TOP",1,"CRLFPOS1"-1)||'\n'||substr("TEXT_TOP","CRLFPOS1"+1,length("TEXT_TOP")-"CRLFPOS1"+1)
WHEN "CRLFPOS1" > 0 AND "CRLFPOS2" > 0
THEN
substr("TEXT_TOP",1,"CRLFPOS1"-1)||'\n'||substr("TEXT_TOP","CRLFPOS1"+1,"CRLFPOS2"-"CRLFPOS1")||'\n'||substr("TEXT_TOP","CRLFPOS2"+1,length("TEXT_TOP")-"CRLFPOS2"+1)
END

Where "CRLFPOS1" is a numeric field with the position the first breakline
And "CRLFPOS2" is a numeric field with the position the second breakline

"TEXT_TOP" is a string field that contain annotations.

I hope that my mail help you ...

Regards,
