Unable to Edit Methods and Properties of a Class Already Added Within a Container Class. (Access and Assign)

I have created a combo box class called TJComboBoxl. It is subclassed from the Mere Mortals class CComboBoxl. I am trying to create an assign method (new to VFP 6.0) in the actual combo box (ComboBox) class (on its value property) which is within the container class TJComboBoxl. I can’t do it. The reason seems to be that when I go to the (Class) / (Edit Method/Property) option on the menu bar, it brings up the properties and methods for the container class (TJComboBoxl), not the class ComboBox. And there doesn’t appear to be any way to add methods or properties to ComboBox within the TJComboBoxl class. It doesn’t look like there is any way to actually add methods and properties of one of the classes within the container class. Am I correct? Or is there a way to add an assign method to a class that is already within a container class?

I guess I will build my own class for this so I can access the classes contained within it, unless anyone has any suggestions or ideas or insight. Does anyone?
