如何在JTable中添加JLabel? [英] How do i add a JLabel in a JTable?

问题描述

所以我想在我的JTable中添加一个带有背景颜色的空JLabel. 这是一个饼图，我想添加它，以便图例匹配.

So i want to add a empty JLabel with a Background color to my JTable. It's for a piechart and i want to add this so the legend matches.

代码:

for (String result : queryResult) {

            JLabel label = new JLabel("Hallo: "+rowCount);
            label.setBackground(colors[rowCount]);
            label.setOpaque(true);

            String queryResultString = "";
            queryResultString = result.toString();
            String[] lineArray = queryResultString.split("////");

            String[] pieData = new String[3];

            pieData[0] = lineArray[0];
            pieData[1] = lineArray[rangId - 1];

            int value = Integer.parseInt(pieData[1]);
            double percentage = value / total * 100;

            pieData[2] = "" + percentage + "%";

            pieModel.addRow(new Object[] {label, pieData[0], pieData[1], pieData[2]});

            rowCount++;
        }

        pieTable.setDefaultRenderer(String.class, new DefaultTableCellRenderer() {

            @Override
            public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column){

                if(value instanceof JLabel){
                    //This time return only the JLabel without icon
                    return (JLabel)value;
                }else{
                    return super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
                }
            }
        });

我在做什么错? :o

What am i doing wrong? :o

当我查看表格第一栏中的结果时，它会说:

When i look at the results in the first column of the table it says:

javax.swing.JLabel [，0,0,0 ...... 看不到其余部分，但它确实无法正常工作！ :(

javax.swing.JLabel[,0,0,0...... can't see the rest but it definetly is not working as it should! :(

您不能通过渲染器来做到这一点默认值Component，JComponent或JLabel

you can't do that Renderer by default returs Component, JComponent or JLabel
