Re: Shapes at Runtime?
In an event handler Sender is always the object which has initiated and
called the event handler.
For IDE placed components Label1Click is allocated to Label1 as the
method called when you click the label. Hence Sender is always Label1.
If you had allocated Label1Click as the OnClick event handler of
something else then other objects could be Sender.
In your Label1Click method the Sender can NEVER be a TShape.
What happened to TManyShapes and all the advice we gave as to how to
make them work. And the advice of not to use "if ... is" AND "as" in
the same statement block.
Are we wasting our time <g>.
