[flext] Basic question about ADDMETHOD

[Thomas Grill]

Hi Martin,
the difference is that ADDMETHOD is used for per-instance methods (they are typically set in the constructur, as you did), whereas CADDMETHOD is for per-class static functions (those are set in a class setup function).
Actually, the use of per-instance methods is not encouraged and will not be supported any longer in future flext versions.
best, Thomas
