-/**
- * TCheckBoxList class
- *
- * TCheckBoxList displays a list of checkboxes on a Web page.
- *
- * The layout of the checkbox list is specified via {@link setRepeatLayout RepeatLayout},
- * which can be either 'Table' (default) or 'Flow'.
- * A table layout uses HTML table cells to organize the checkboxes while
- * a flow layout uses line breaks to organize the checkboxes.
- * When the layout is using 'Table', {@link setCellPadding CellPadding} and
- * {@link setCellSpacing CellSpacing} can be used to adjust the cellpadding and
- * cellpadding of the table.
- *
- * The number of columns used to display the checkboxes is specified via
- * {@link setRepeatColumns RepeatColumns} property, while the {@link setRepeatDirection RepeatDirection}
- * governs the order of the items being rendered.
- *
- * The alignment of the text besides each checkbox can be specified via {@link setTextAlign TextAlign}.
