Thanks for the tip Paul. Unfortunately it did not help. See for the results below.

Delphi mode:

class  -> Error: Incompatible types: got "class TfpgGLApplication.CDisplayFunc; CDecl;" expected "<procedure variable type of procedure;CDecl>"
static -> Error: Incompatible types: got "class TfpgGLApplication.CDisplayFunc; CDecl; Static;" expected "<procedure variable type of procedure;CDecl>"

ObjFPC mode:

class  -> Error: Incompatible types: got "<class method type of procedure of object;CDecl>" expected "<procedure variable type of procedure;CDecl>"
static -> Error: Incompatible types: got "<class method type of procedure of object;CDecl>" expected "<procedure variable type of procedure;CDecl>"

I was surprised that under objfpc there is no difference in error message.
