How to position the cursor on the right-hand side of a TEdit
Problem/Question/Abstract:
I want to write an Edit component, but I want the cursor to stay on the right when the user types in new characters.
Answer:
procedure TForm1.Edit1Change(Sender: TObject);
begin
if IsChanging then
exit; {Avoid recursion}
IsChanging := true;
try
{Remove the first character}
Edit1.Text := copy(Edit1.Text, 2, length(Edit1.Text) - 1);
{And move the cursor to the end of the text}
Edit1.SelStart := length(Edit1.Text);
finally
IsChanging := false;
end;
end;
At design time (or in Create), put several spaces as Edit1.Text. They will be replaced one by one with characters typed by the user. IsChanging is a private variable of type boolean.
