TLabel is a TCustomLabel descendant which implements a control to display static text on a form. The value in the control is not editable visually, and can be used to label or describe another control on the form or a container. Since it cannot be edited, it is not allowed to receive the input focus. It can, however, be used to set focus to an associated control using an accelerator key defined in the Caption for the control.
Use TStaticText to display static text and respond to keyboard input directly in the control.
