Hello,
Attempting to use the Data Defined function (tool?).
The following configuration has no effect; it may be looking for a
colour input. This DD is to set the background colour on a label where Type
= SL.
If I use this function on bold Text, it works but that requires no
input, it just toggles.
Where am I supposed to enter the "Expected Input" colour specifications?
The expression needs to evaluate to a color string, whereas your
expression evaluates to a boolean value.
Something like this is acceptable:
case when "Type" = 'SL' then '#ff0000' else '#00ff00' end
Nyall
Data defined override
Active: yes (ctrl|right-click toggles)
Expected input:
string [r,g,b,a] as int 0-255
Valid input types:
string
Current definition (expression):
"Type" = 'SL'
Thanks very much . . . .
Cheers . . . . . Springfield Harrison
