BooleanChecker Class

Class that adds extra checkboxes to header and group cells of FlexGrid boolean columns to allow setting the values for all items or groups.

** Note **: When you attach a BooleanChecker to a Column, you may also want to set the column's Column.aggregate property to Aggregate.First, so the grid will create cells on group header rows to hold the checkboxes used to set the boolean values for the groups.
