| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: object
Returns or sets with setf the value of the selected property of the argument.
object may be a menu-item
. A selected menu-item
will usually
be displayed with a check mark next to its title when the menu is
displayed. (On GTK, the checkable property of the menu-item must also be
true.) However, if its cluster property is
true, then it will be displayed with a dot
instead of check mark, and any other menu-items in the same cluster
will be deselected automatically, making a set of menu-items act
similar to a group of radio-button
controls.
object may be a grid-row
or grid-column
(on a grid-widget
) in which
case the cells within in it are drawn using cell-selected-foreground-color and
cell-selected-background-color
rather than the usual cell-foreground-color and cell-background-color.
The only other built-in behavior of a selected row or column is to be
the object of delete-selected-subsections if it
is called, but an application may choose to treat selected rows and
columns in a custom way.
For a grid-row
or grid-column
(on a grid-widget
), an application may
call (setf
selected) to programmatically select or deselect individual
rows and columns; in addition, (setf selected)
will be called automatically if the user left-clicks a cell whose
grid-row
or
grid-column
has a true selectable property and the
intersecting column or row is an instance of row-selecting-column-mixin
or
column-selecting-row-mixin
(respectively). (This is the default interactive behavior that could
be overridden by a more specific cell-click method.) See also
cell-selected,
selectable, selected-reader,
and deselect-all-subsections.
selected may also
be called on an outline-item
or a list-view-item
, in
which case it will return true if and only if the value of the associated outline or list-view currently is
(or contains) the value of the outline-item
or list-view-item
. But
an application should never call (setf selected) on
an outline-item
or list-view-item
, and
instead should call (setf value) on the associated outline
or list-view
control.
selected is a
property of the grid-subsection
, grid-column
, row-header-column
,
grid-row
,
column-header-row
, outline
, list-view
, and menu-item
classes.
