The constructor is called _new in Gambas (see [1]):

  Public Sub _new()
    ' runs on object creation
  End

You can also specify parameters to the _new() method like

  ' In MyClass.class:
  Public Sub _new(X As Integer)
    ' ...
  End

which demands that an Integer be given on object instantiation:

  Dim h As New MyClass(10) ' X = 10
