Creating components at runtime - Delphi

Question

How can I create a component at runtime and then work with it (changing properties, etc.)?

Answer 1

To simplify the runtime component creation process, you can use GExperts.

1. Create a component (or more components) visually and set its properties.
2. Select one or more components and execute GExperts, Components to Code.
3. Paste the generated code into your application.
4. Remove component(s) from the visual form designer.

Example (TButton-creation code generated in this way):

var
  btnTest: TButton;

btnTest := TButton.Create(Self);
with btnTest do
begin
  Name := 'btnTest';
  Parent := Self;
  Left := 272;
  Top := 120;
  Width := 161;
  Height := 41;
  Caption := 'Component creation test';
  Default := True;
  ParentFont := False;
  TabOrder := 0;
end;
