[Gambas-user] How to wait until form is closed

[wig]

I made two forms in the IDE.

I want the form Test2 only to appear after the form Test1 is closed.

Can I let the program wait for the first Form to be closed?

PUBLIC SUB Main()

  FormTest1.Show()
  ' wait till FormTest1 is closed ?
  FormTest2.Show()
