TBitBtn.Visible property
Indicates if the control is visible on its parent.
Declaration
property Visible:;Description
The Visible property indicates the ability to see a visual
control. If Visible is True, the control is shown,
otherwise it is hidden. Calling Show sets Visible to
True. Setting Visible to False is equivalent to
calling the Hide method.
The
Visible property does not depend on the visibility of a parent
control. Use IsVisible method to consider this, and get the real
visibility for a control in its parent container.
