Sun - Java Look and Feel Design Guidelines, 2nd Edition made by dotneter@teamfly In range selection, the selection always extends from the column with the anchor point to the column where the user has Shift-clicked. If users Shift-click within an existing selection, the selection becomes smaller. Multiple Ranges of Columns You can enable users to select a single column, a range of columns, or multiple-column ranges (also known as “discontinuous,” “discontiguous,” or “disjoint” ranges). Users select a single column by clicking any cell in the column and extend the selection by Shift-clicking. To start another range, users Control-click any cell in the column. The cell gets keyboard focus and becomes the anchor point of the range. The selection of the column toggles as follows: If the column is not already selected, it is selected. A subsequent Shift-click selects all columns from the anchor point to the column where the user Shift-clicked. If the column is within an existing selection, the column is deselected. A subsequent Shift-click deselects all columns from the anchor point to the column where the user Shift-clicked. Users can also select or deselect another range by dragging through the range while holding down the Control key. In the following figure, the user has clicked Peter and then Shift-clicked Amann. The user has selected another range by Control-clicking Krakatoa, which has keyboard focus and can be edited, as indicated by its white background. Figure 198 Multiple Ranges of Selected Columns
