Delphi-当用户输入第一个文本时，如何将文本从一个文本复制到另一个文本？

Question

There are two tedit

One is enabled for the user, and the other disabled.

The moment user types anything in the tedit, the same thing gets typed in the disabled tedit, while the user is typing.

I don't want to use any buttons for this.

How to implement this in Delphi?

Answer 1

You can use the OnChange event of your first TEdit and set text of the second edit to the text of the first. This should look like

procedure TForm1.Edit1Change(Sender: TObject);
begin
  Edit2.Text := Edit1.Text;
end;
