                      The ob_state field of an OBJECT
                               (Object States)


The ob_state field determines the display state of the OBJECT as follows:

Name      Bit   Mask    Meaning

SELECTED   0   0x0001   The object is selected. An object with this bit
                        set will be drawn in inverse video except for
                        G_CICON which will use its 'selected' image.

CROSSED    1   0x0002   An OBJECT with this bit set will be drawn over
                        with a white cross (this state can only usually be
                        seen over a colored or SELECTED object).

CHECKED    2   0x0004   An OBJECT with this bit set will be displayed with
                        a checkmark in its upper-left corner.

DISABLED   3   0x0008   An OBJECT with this bit set will ignore user
                        input. Text objects with this bit set will draw in
                        a dithered pattern.

OUTLINED   4   0x0010   G_BOX, G_IBOX, G_BOXTEXT, G_FBOXTEXT, and
                        G_BOXCHAR OBJECTs with this bit set will be drawn
                        with a double border.

SHADOWED   5   0x0020   G_BOX, G_IBOX, G_BOXTEXT, G_FBOXTEXT, and
                        G_BOXCHAR OBJECTs will be drawn with a shadow.

The AES supports the objc_change() call which can be used to change the
state of an object and (optionally) redraw it.
