Delphi Mysql passing Login data to another form

[drama22]

i have created 2 forms A login form & A main form i successfully logged in To the main form
here is the code that i use to login

Delphi-Quellcode:

 SQL := Tloginclass.Create;
  try
    SQL.Login:= trim(Usrnm.Text);
    SQL.passwd := trim(passwd.Text);
    if SQl.logins then
     begin
      LoginSuccess := True;
     end

i retrieve and validate logins from a unit class wich is Tloginclass ,,

but now how to i set the data for each user logged in to the main form ?

i try somthing like this after login
Mainform.listusers.Items.Add(SQL.Login); but this is not logical because this showing only text how the application know the differents between user who loggedin like there is bob and martin and james ,etc are online now and read there user names ? any idea about this iam trying to understand the logic of this concept.
