Why is ToolBarButton class not a control?

It seems to me that the ToolBarButton should be a control, but instead it
inherits from Component. Is there a reason this could not have inherited
from Control since really a ToolBarButton is nothing more then a button with
additional features?

I doubt that every button on a toolbar is really implemented as a
regular button. More probably, the "buttons" on a toolbar are
something like the items in a ListView, or the individual checkboxes
in a CheckedListBox: it's the responsibility of the parent control to
paint them all.

Is there something you're trying to do that you can't achieve this
way?

I just had code that tracks the location of a control and wanted to expand
it to the toolbar buttons. Right now I have a constructor that takes a
Control object. This means that any control can be monitored by my class.
Now, if I want a ToolBarButton to be tracked, I have to add a new
constructor for this and generalize some of my code. Although it is not a
problem, it just means more methods.

I just thought that it really should have been a control since it has visual
characteristics and has behavior like all other controls. The ToolBar could
have been something like a Panel (or some other container), that allowed
other controls to be embedded.
