示例1: showJList
import javax.swing.JList; //導入方法依賴的package包/類
private void showJList (JScrollPane view, Point pt) {
JList list = (JList) view.getViewport().getView();
Point p = SwingUtilities.convertPoint(view, pt.x, pt.y, list);
int row = list.locationToIndex(p);
if (row == -1) {
hide();
return;
}
Rectangle bds = list.getCellBounds(row,
row);
//GetCellBounds returns a width that is the
//full component width; we want only what
//the renderer really needs.
ListCellRenderer ren = list.getCellRenderer();
Dimension rendererSize =
ren.getListCellRendererComponent(list,
list.getModel().getElementAt(row),
row, false, false).getPreferredSize();
bds.width = rendererSize.width;
if (bds == null || !bds.contains(p)) {
hide();
return;
}
if (setCompAndRow (list, row)) {
Rectangle visible = getShowingRect (view);
Rectangle[] rects = getRects (bds, visible);
if (rects.length > 0) {
ensureOldPopupsHidden();
painter.configure(
list.getModel().getElementAt(row),
view, list, row);
showPopups (rects, bds, visible, list, view);
} else {
hide();
}
}
}
示例2: getIndexAt
import javax.swing.JList; //導入方法依賴的package包/類
public static int getIndexAt(JList list, Point point) {
if (point == null)
return list.getSelectedIndex();
return list.locationToIndex(point);
}
