[SOLVED] Handling Enabled property

If I drop a groupbox on a form, and drop a label on the groupbox. The
labels apperance will reflect the state of the enabled property of the
groupbox. This is normal. If I create a component based on
TCustomcontrol, how can I "catch" if the state of the enabled property
of the parent control changes?

I have attached a demo that shows the issue.
A standard label on the custom groupbox will reflect the groupboxes
enabled state, whereas the custom label will not, but if the custom
label is placed on a standard groupbox it works.

All custom controls are made at runtime.
