Description
The DODEFAULT() function is used to call the parent class method from within a sub-class. It can only be used within a class method. It calls the parent class method of the same name as the calling method. It allows a sub-class to perform the default parent class behavior along with additional behavior specific to that particular sub-class.
Example
class Box procedure Draw messagebox("This is the parent Draw Method") endproc && Draw endclass class Dialog1 of Box procedure Draw messagebox("This is the object Draw Method") // call the Draw method of the Box parent class dodefault() endproc && Draw endclass oDIALOGOK = createobject("Dialog1") oDIALOGOK.Draw() release oDIALOGOK
