How to access component's properties without knowing its name?

Question

Is there a way to use the properties of a component created in run-time without knowing its name? And by this I mean after you already done this.

with TPanel.Create(self) do
  begin
  Name := 'Panel' + IntToStr(ComponentCount + 1);
  Height := 50;
  Width := 100;
  Top := 30;
  Left := 30;
  Parent := self;
  end;

Store the objects in a container, like `TList` – whosrdaddy Feb 18 '17 at 11:57 — whosrdaddy, Feb 18 '17 at 11:57

Declare a variable of type TPanel and store a reference to your component in that variable.

var
  Panel: TPanel;
.... 
Panel := TPanel.Create(Self);

You can then refer to the control using this variable.

You will likely need to hold the variable as a member field of the form, or in an array, or indeed some other container.

They can't all be called panel1 then. Store them in an array or another container, as it says in the answer. – David Heffernan Feb 18 '17 at 08:12

It doesn't matter. The answer is the same. – David Heffernan Feb 18 '17 at 08:25
You know, after 8 months, I think I would like to say I'm sorry I accepted the other answer instead of yours. I should've known better (well I did not have the same knowledge as I do now). thank you for your help. – Nasreddine Galfout Nov 11 '17 at 00:10
And by the way, The container I'm using to store the panels is `TList` (the generics version). – Nasreddine Galfout Nov 11 '17 at 00:13
