Hello all,
Where can I find the syntax for filtering using Selection Filter widget with Regular Expressions?
I'm trying expressions like "2+1", "=2+1", etc. but they are not working...
Thanks!!
David

Regular expressions can be used to define a search pattern. Regular expressions can be very complex, but there are also some simple but useful ones:
"ABC.*" matches layers starting with "ABC"
".*ABC" matches layers ending with "ABC"
".*ABC.*" matches layers containing "ABC"
"[1-4]" matches numbers 1 to 4
"\d" matches a digit
More information:

and others...
This examples would match everything on layers "layer 2" and "layer 3":
