I have a class, THPTree, that is derived from TCustomTreeView and
has a property called FormView of class type TfrmView. That class
is derived from TForm. On creation of an instance of THPTree I want
to set the property FormView to nil. In some circumstances I want to
allocate an instance of TfrmView save it in the FormView property.
Other times I want to make this form visible and set focus to it. I cannot
get this to work.
My questions are:
- how do I assign an instance of TfrmView to the property FormView?
- how do I test to see if FormView is a form (of class TfrmView ) or nil?
I think that what I am asking is how do I complete the two functions for
reading and writing the value of the property. The property is defined
Property FormView: TfrmView read GetFormView write SetFormView;
Any help would be most appreciated.
Chrissy.
