RE: Re: SV: [Dynapi-Dev] Widget constructor

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

but how to handle extra arguments specific for a widget?
the DynAPI arguments are optional, so there are not always 8 arguments for
the DynLayer (width,height,position,etc)

there for what's the first widget argument ?
