Object Oriented In Graphic Languages

In graphic languages, in case the object oriented programming is enabled, GF_ProjectVX code will prompt a dialog to ask the user which element he wish to select in case of ambiguity.For example: if you have a function block with methods and you drag it into an FBD pro- gram source editor, GF_ProjectVX code will ask you if you want to call the body of the function block or a specific method.
