\brief FLTK standard box types

|

This enum defines the standard box types included with FLTK.
|

|
||
\note The documented \p enum \p Fl_Boxtype contains some values (names)
|
||
with leading underscores, e.g. \p \b _FL_SHADOW_BOX. This is due to
|

technical reasons - please use the same values (names) without the
|

leading underscore in your code! Enum values with leading underscores

are reserved for internal use and subject to change without notice!
|

FL_NO_BOX means nothing is drawn at all, so whatever is already
|

on the screen remains. The FL_..._FRAME types only draw their edges,
|
||
leaving the interior unchanged. The blue color in the image below
|
||
is the area that is not drawn by the frame types.
