Subject: [DUG]: [Q] Common Ancestor - TCanvas....
G'Day All,
As part of a component I would like one of the properties to be a list of
controls that have a canvas property. Now I realise that I could traverse
all the components owned by the form to determine if it had a TCanvas
property. However what I don't understand is:
- What type do I make the property? TPersistent?
- If I did the above there would be a need to typecast the property. There
must be a better way to do that aside from if The_Control is TImage then
TImage(The_Control).Canvas etc.
Any pointers etc. would be greatly appreciated.....
