You have two ways of doing that in Gambas:

1) You can create what you do in a form, and use the form as any control in 
your code.

Let's suppose your form is named FMyListBox.

In your FMyChat main form, you do:

PRIVATE $hMyListBox AS FMyListBox

PUBLIC SUB _new()

  $hMyListBox = NEW FMyListBox(ME)
  $hMyListBox.Move(10, 10, 100, 100)

END

You have an example of that in the IDE source code: the FSelector form is used 
as a control in many other forms, like FOpenProject

2) You can create a class that manage your list box.

Let's suppose this class is named CMyListBox. Its code is:

PRIVATE $hScrollView AS ScrollView

PUBLIC SUB _new(hParent AS Container)

  $hScrollView = NEW ScrollView(hParent)
  ...

END

You have an example of that in the IDE source code: there is a class named 
CCoolButton that implements the buttons of the welcome dialog, those who 
become blue when the mouse is over them.

I can't help you more, except by writing the code for you :-)

Maybe anyone more advance than you could write an example of that ?
