JToolbar背景图片

我正在使用自定义的 JToolbar，代码如下：

public class GeneralToolbar extends JToolBar{

  public GeneralToolbar() {
    super();
    setBackground(Color.white);
    setOpaque(true);
    setPreferredSize(new Dimension(54,54));
    setMinimumSize(new Dimension(54,54));
    setMaximumSize(new Dimension(54,54));
    setSize(new Dimension(54,54));
  }

  public void paintComponent(Graphics g) {
    super.paintComponent(g);
    Dimension size = this.getSize();
    ImageIcon image = DefaultAction.createImageIcon("/com/aaa/resources/tabback");
    g.drawImage(image.getImage(), 0,0, size.width, size.height, this);
  }
}

现在可以看到图像了。但我的按钮周围有一个不透明的矩形。我尝试将按钮不透明设置为 false，但它没有添加任何影响。感谢您的支持

I'm using a customized JToolbar using the following code:

public class GeneralToolbar extends JToolBar{

  public GeneralToolbar() {
    super();
    setBackground(Color.white);
    setOpaque(true);
    setPreferredSize(new Dimension(54,54));
    setMinimumSize(new Dimension(54,54));
    setMaximumSize(new Dimension(54,54));
    setSize(new Dimension(54,54));
  }

  public void paintComponent(Graphics g) {
    super.paintComponent(g);
    Dimension size = this.getSize();
    ImageIcon image = DefaultAction.createImageIcon("/com/aaa/resources/tabback");
    g.drawImage(image.getImage(), 0,0, size.width, size.height, this);
  }
}

Now the image is seen. But I get a opaque rectangle around my buttons.
I tried to set the button opaque to false but it didn't add any affect.
Thank you for the support

也许你需要使用：

button.setBorderPainted( false );
button.setContentAreaFilled( false );

当然当你去掉Border之后，那么你就看不到点击按钮的效果了。

如果您需要更多帮助，请发布显示问题的 SSCCE。

Maybe you need to use:

button.setBorderPainted( false );
button.setContentAreaFilled( false );

Of course when you get rid of the Border, then you don't see the effect of clicking on the button.

If you need more help post your SSCCE showing the problem.
