''' SimpleFormWithControls.py

This demo shows a subclass of dForm populated by
dControl instances. Since this demo isn't connected
to any data, we only need to import the ui layer.

A good amount of the 'bulk' in this code has to do
with setting up the vertical and horizontal sizers.

This sample does not connect to a dApp object at all,
so certain features, such as the form remembering its
size and position, will not work. It does demonstrate
how individual parts of Dabo can work independently from
the whole.
