我需要为我的JTree使用自定义单元格渲染器在每个单元格上添加一些JLabel.然后允许用户单击这些标签,而无需先选择单元格.

所以,我创建了一个Renderer,它返回一个包含DefaultTreeCellRenderer和2个JLabel的JPanel.

    public class TreeNodeRenderer extends DefaultTreeCellRenderer implements TreeCellRenderer
    {
        private JPanel panel1 = new JPanel();
        private JLabel delete = new JLabel("");
        private JLabel upload = new JLabel("");

        public Component getTreeCellRendererComponent(JTree tree, 
                            Object value,
                boolean selected, boolean expanded, boolean leaf, int row,
                boolean hasFocus) 
        {   
            //
            // DELETE label
            //
            delete.setName("delete");
            delete.setIcon(new ImageIcon("Data/trash.png"));

            //
            // UPLOAD label
            //
            upload.setName("upload");
            upload.setIcon(new ImageIcon("Data/app_up.png"));


            DefaultTreeCellRenderer defaultRenderer = new DefaultTreeCellRenderer();
            Color backgroundSelectionColor = defaultRenderer.getBackgroundSelectionColor();
            Color backgroundNonSelectionColor = defaultRenderer.getBackgroundNonSelectionColor();

            if(selected)
                panel1.setBackground(backgroundSelectionColor);
            else
                panel1.setBackground(backgroundNonSelectionColor);


            component = …

我正在创建一个Outlook加载项,我想知道如何从选定的日历中获取元素？例如,我需要从名为"myCalendar"的日历中获取所有约会项目.现在,我可以从所有日历中获取所有约会项目.

谢谢,
