+This block creates a variable check box. \
+Leave the label blank to use the variable id as the label.
+
+A check box selects between two values of similar type. \
+Te values do not necessarily need to be of boolean type.
+
+The GUI hint can be used to position the widget within the application. \
+The hint is of the form [tab_id@tab_index]: [row, col, row_span, col_span]. \
+Both the tab specification and the grid position are optional.
