是否可以在JLayeredPane()
内添加JTable
?
我试过了:
JLayeredPane agentPicturePane = new JLayeredPane();
String agentPicture = "http://www.domain.com/uploads/thumb_23.jpg";
try {
final BufferedImage image = resize(new URL(agentPicture), new Dimension(60, 60));
jLabel1.setIcon(new javax.swing.ImageIcon(image));
} catch (Exception ex) {
}
jLabel6.setIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/imageBg.png")));
jLabel1.setBounds(13, 13, 60, 60);
jLabel6.setBounds(0, 0, 86, 86);
agentPicturePane.setPreferredSize(new Dimension(86, 86));
agentPicturePane.add(jLabel6, new Integer(50));
agentPicturePane.add(jLabel1, new Integer(100));
visitorModel.addRow(new Object[] {
agentPicturePane, visitorName, visitorClose
});
使用模型:
visitorModel = new DefaultTableModel(productss, colNamee) {
@Override
public boolean isCellEditable(int row, int column) {
//all cells false
return false;
}
public Class getColumnClass(int column) {
// return getValueAt(0, column).getClass();
return (column == 0 || column == 2) ? Icon.class : Object.class;
}
};
任何想法如何做到这一点?
最佳答案
您混淆了自己的责任范围。 TableModel
仅假定携带数据。由视图决定如何呈现该数据。
如果需要提供某种自定义呈现,则需要提供TableCellRenderer
本示例使用复合JLabel
和EmptyBorder
提供叠加功能。
因此,使用下面的两个图片...
我能够生产...
