Question

我有一个Jtable，每行都有一个按钮来删除该行。文本设置为＆＃34;删除＆＃34;。当我选择按钮时，文本消失。如何设置所选按钮的文本？

渲染器：

String s = "1-234-56s78===90";
System.out.println(s.chars().filter(i -> i >= '0' && i <= '9').distinct().count() == 10);

编辑：

public class JButtonRenderer  extends JButton implements TableCellRenderer {

    public JButtonRenderer(){
        this.setText("Delete");
    }

    @Override
    public Component getTableCellRendererComponent(JTable arg0, Object arg1, boolean arg2, boolean arg3, int arg4,
            int arg5) {
        return this;
    }
}

尝试将此课程与TableCellEditor，TableCellRenderer

一起使用

class JButtonRenderer extends AbstractCellEditor implements TableCellEditor, TableCellRenderer {

        public JButtonRenderer() {
        }

        @Override
        public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
            JButton b = new JButton("Delete");
            return b;
        }

        @Override
        public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, final int row, int column) {
            JButton b = new JButton("Delete");
            b.addActionListener(new java.awt.event.ActionListener() {

                @Override
                public void actionPerformed(ActionEvent e) {
                    // code
                }
            });
            return b;
        }

        @Override
        public Object getCellEditorValue() {
            return null;
        }

        @Override
        public boolean isCellEditable(EventObject anEvent) {
            return true;
        }

        @Override
        public boolean shouldSelectCell(EventObject anEvent) {
            return true;
        }
    }

并使用：

JButtonRenderer compCellDelete = new JButtonRenderer();

jTable1.getColumnModel().getColumn(your_column_index).setCellEditor(compCellDelete);
jTable1.getColumnModel().getColumn(your_column_index).setCellRenderer(compCellDelete);

JTable中的JButton：Button工作，但文本在点击时消失
