SV: [Dynapi-Dev] Widget constructor

[Bart B. <ba...@ho...>]

Hmm... does not seem to work at all.
IE4 says it doesn't support the property or method.
Could you elaborate, or send me an example of this being used somewhere?
Another problem: DynLayer treats objects sent as the first argument as a DynLayer object to setStyle after.
And as arrays(the array arguments in this case) are objects and correspondingly are identified as such, the setStyle method will be called, which is not the intent.
