A range selector component displays and enables the definition of discontiguous sub-ranges from within a range. The component implements a paint mechanism for displaying the range selector component and one or more discontiguous sub-ranges within the range of the component; and implements mouse listener interfaces so as to respond to pointer interaction with the rendered range selector component, for defining the one or more discontiguous sub-ranges. In particular, the selector is responsive to pointer selection within a sub-range to split the sub-range into two sub-ranges. |
