X; Int y = jtable1.getrowheight () * rowindex; Int width = jtable1.getbounds (). width; Int Height = jtable1.getrowheight (); Jtable1.scrollrecttovisible (New rectangle (X, Y, width, height ));

1. Define JList 2. Add mouse Monitor on the JList object (MouseListener) 3. After the Click event is triggered, determine its position in the jlist, and then determine the number of hits, depending on the number of times to select the processing function.
