Arguments: grid-subsection
Returns the value of the selectable property of the
argument. This property determines whether the grid-row or -column can
be selected by
clicking it. When a row or column is selected, it is drawn in the
selection colors that the user has set up in the Windows Control
Panel. Other than being drawn differently, the only special behavior
that is built into a selected row or column is that all
selected rows and
columns that are also deletable will be deleted from a grid-widget
if the
user presses the DELETE key while the grid-widget has the keyboard
focus. If other special behavior is desired for selected rows and column, it is up
to the application to check the selected property of each row or
column and treat it accordingly.
A selectable grid-row
may be selected
interactively only by clicking it in its cells that also lie in
columns that are instances of row-selecting-column-mixin
.
Likewise, a selectable grid-column
may be selected
interactively only by clicking it in its cells that also lie in rows
that are instances of column-selecting-row-mixin
.
The setf of this function may be called at runtime to change the selectable status of a row or column.
selectable is a
property of the grid-subsection
, grid-column
, row-header-column
,
grid-row
, and
column-header-row
classes.
