我正在使用GridBagLayout制作一个StatusBar,看起来像图片中的那样。我有4个区域,所以我在第一个区域中有一个按钮,然后在第二个区域中有信息消息,然后我想再有两个区域(并且我也有第5个区域作为角落)。

按钮区域非常适合,因为内容始终是宽度相同的按钮。与拐角区域相同。信息区域必须获取所有可用空间。第三和第四区域必须具有固定值,与屏幕大小无关。

我怎样才能做到这一点?

我当前的代码是:

public MyStatusBar() {
        setLayout(new GridBagLayout());
        setPreferredSize(new Dimension(getWidth(), 23));
        GridBagConstraints c = new GridBagConstraints();

        botonDispositivo = new JButton("");
        this.setText(0, "Disconnected");
        URL imageUrl = getClass().getResource("resources/22x22/dispositivo01.png");
        this.setButtonImg(imageUrl);
        this.setButtonEnabled(false);


        c.gridx = 0;
        c.gridy = 0;
        c.fill = GridBagConstraints.BOTH;
        c.anchor = GridBagConstraints.WEST;
        c.gridwidth = 1;
        c.gridheight = 1;
        this.add(botonDispositivo, c);

        c.insets= new Insets(0,10,0,0);
        c.gridx ++;
        c.gridy = 0;
        c.weightx = 0.7;
        c.fill = GridBagConstraints.HORIZONTAL;
        msgLabel = new JLabel("");
        msgLabel.setPreferredSize(new Dimension(500, msgLabel.getHeight()));
        this.add(msgLabel, c);
        this.setText(1, "Waiting for potentiostat conection");

        c.gridx ++;
        c.gridy = 0;
        c.weightx = 0.0;
        c.fill = GridBagConstraints.NONE;
        this.add(new SeparatorPanel(Color.GRAY, Color.WHITE), c);

        c.gridx ++;
        c.gridy = 0;
        c.fill = GridBagConstraints.NONE;
        c.weightx = 0.0;
        overErrorLabel = new JLabel("");
        overErrorLabel.setSize(new Dimension(150, overErrorLabel.getHeight()));
        this.add(overErrorLabel, c);
        //this.setText(2, "");

        c.gridx ++;
        c.gridy = 0;
        c.weightx = 0.0;
        c.fill = GridBagConstraints.NONE;
        this.add(new SeparatorPanel(Color.GRAY, Color.WHITE), c);

        c.gridx ++;
        c.gridy = 0;
        c.weightx = 0.0;
        c.fill = GridBagConstraints.NONE;
        c.anchor = GridBagConstraints.EAST;
        timeLabel = new JLabel("");
        timeLabel.setMinimumSize(new Dimension(150, timeLabel.getHeight()));
        //timeLabel.setMaximumSize(new Dimension(150, timeLabel.getHeight()));
        this.add(timeLabel, c);
        //this.setText(3, "");


        JPanel rightPanel = new JPanel(new GridBagLayout());
        c.gridx ++;
        c.gridy = 0;
        c.weightx = 0.0;
        c.fill = GridBagConstraints.BOTH;
        rightPanel.add(new JLabel(new AngledLinesWindowsCornerIcon()), c);
        rightPanel.setOpaque(false);

        c.gridx ++;
        c.gridy = 0;
        c.fill = GridBagConstraints.BOTH;
        this.add(rightPanel, c);

        setBackground(SystemColor.control);
      }

最佳答案

为了更好,最轻松地输出到GUI,最好查找Borderlayout
JPanel#setPrefferedSize(200, 30);JButton,并将Icon和JLabel放入WEST areaJPanel#setPrefferedSize(200, 30);(rightPanel)到EAST area
将另一个JPanel放入CENTER area
