Parameters:
* method (or enum) node
* string containing the whole param list
* 1 for enums
Adds a property "ParamList" to the method node.
This property contains a list of nodes, one for each parameter.
Each parameter node has the following properties:
* ArgType the type of the argument, e.g. const TQString&
* ArgName the name of the argument - optionnal
* DefaultValue the default value of the argument - optionnal
For enum values, ArgType is unset, ArgName is the name, DefaultValue its value.
