Create additional 'this' parameter for class methods

User interface > Translation options > Tuning options > Create additional 'this' parameter for class methods

The tuning option Create additional 'this' parameter for class methods is set to false by default. If it is  true in the generated code the parameters of class methods are preceded by an extra parameter, which represents the Delphi Self type, as explained here. If Self isn't used by your code and if the code also doesn't use virtual class methods, this options may be unchecked.
