[Gambas-user] What has happened to ValueBox

OK I see!

The ValueBox of Gambas 2 inherits TextBox, and so when it raises events, LAST 
is always a ValueBox.

The current ValueBox of Gambas 3 is actually a compound control (it inherits 
UserControl), with a edit control inside that can be a TextBox or another 
control. Events raised by the edit control are propagated as if the ValueBox 
raise it. But then LAST is the read TextBox, not the ValueBox.

Moreover, the code of that ValueBox is somewhat dirty. So I plan to rewrite it 
differently, and makes it inheriting TextBox again, or find a way to propagate 
events and keep LAST to be the ValueBox.

Sorry for the inconvenience. It will disappear when the ValueBox will be 
rewritten.

As a workaround, you can check the type of LAST. And when it is a TextBox, 
take its parent to get the ValueBox.

Maybe another bug then. I will investigate.
