Mmm... You're right, a Change event would be useful... I will see if I 
can add it...

As a workaround, you can create an observer on the first inner child of 
the control to catch it.

hObs = New Observer(TheValueBox.Children[0]) As "TheValueBox"
...
Public Sub TheValueBox_Change()
...
End

But beware that you must do it just after having set the Type property 
(because it recreates the inner widget each time you change the ValueBox 
type).
