A non-instantiable class that can be mixed with the grid-column class to
create grid columns whose cells act like check-box controls. Each cell in
the column will implement the pseudo-control if the row of that cell
is an instance of a grid-row subclass that mixes in the
widget-row-mixin class.
When the user clicks the check-box gadget displayed in the cell, the
cell-click method
provided by this mixin calls write-cell-value with a value of
either t or nil so
as to change the domain value represented by the cell. Alternately
the user may press the spacebar or the enter key to simulate clicking
the check-box.
The title-reader property of the column should be used to determine the string to display in each check-box cell. The click-must-be-on-gadget property may be used to determine where the user must click within the cell to activate the cell's gadget.
