_unknown

The _unknown method is called when the interpreter didn't find a method or property symbol in the class declaration.

This method takes a variable number of arguments, and returns a Variant value.

Inside the implementation function:

• The /wiki/api/name/gb.isproperty function will tell you if the unknown symbol was used as a property or as a method.

• The /wiki/api/name/gb.getunknown function will return the name of the unknown symbol.

• The /wiki/api/name/gb.nparam function will return the number of arguments passed to the function.

The application class of the gb.qt.kde component is a good example of the use of this feature. When you do a DCOP call, the interpreter doesn't know if the application is loaded, if the method exists, what its parameters are, and so on. So the _unknown special method is welcome !
