是的,在集装箱标签上使用带盒式的JLabel:

JLabel container = new JLabel();
container.setLayout(new BoxLayout(container, BoxLayout.X_AXIS));
JLabel icon1Label = new JLabel();
JLabel icon2Label = new JLabel();
icon1Label.setIcon(icon1);
icon2Label.setIcon(icon2);
container.add(icon1Label);
container.add(icon2Label);

Try CompoundIcon Edit: Heisenbug s layout-based solution is the trivial answer.

我只是最近才这样做了——我希望能够把单行的多个电灯合并为一个单行。 我这样做的方式是,将两个图像按手写成单一图像,然后作为我的<条码>。 还有其他实现同样效果的办法,但我确实不想改变我的核心要素。

我最后创建了一个组合多种图像和藏匿的班子。 我这样说:

ImageIcon icon1 = ...;
ImageIcon icon2 = ...;

ImageIcon labelIcon = new CachedCompositeIcon( icon1, icon2 ).getIcon();
jLabel.setIcon( labelIcon );

这样做是完全可能的,JLabel正在上任,你可以向另一名JComponent增加任何JComponent,而JLabel的情况也是如此。

label.setLayout(new GridLayout(0, 2, 10, 10));
label.add(myIcon1);
label.add(myIcon2);

if you add f.e. JPanel to the JLabel then don t forget to setOpaque(false);
