 |
|
I am wondering what the advantage of using the FindComponent function
rather than the "Initialization - RegisterClasses"?
The reason I am wondering about this is: I created a form the normal
way. Than I go and use the "OOP Form Wizard" and it removes the
"Initialization - RegisterClasses" routine in the FormCreate procedure
and adds a FindComponent statement for each component on the form. My
thought is that the purpose for this is to save memory, is this true
and are there other advantages to this?
Thanks for the help,
Wade

Every control reference in your form is exposed as Public. If you make them
private then the Delphi streaming mechanism cannot find them in order to
assign their references and they all remain nil.
You can make them Private, and use FindControl to assign the references
instead. This gives the advantage that not all control references are
accessible from other classes.

Hey Pete,
It's actually published, not public. Semantically, there's no real
difference, I know, but being published is what allows them to be accessed
by the streaming system.
