selectable

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.
