Question 1

我想作以下阐述:

>

(i) jbutton和jlabel被安置在jpanel,jbutton被集中,jlabel紧随其后。退约应当能够转作。 <><>Edit>: 溶解期间,吉布顿和支拉布的面积保持不变。

我想到以下几点:

<ol>
<li>使用适当的排位管理人。我不知道。我可以把jbutton和jlabel添加到另一个支架上,并将这一新的支架添加到大吉普勒的中心,但在这种情况下,jbutton获胜的帽子被集中起来。

Edit: I tried to use <a rel= this proposal: (proposal was edited and code is correct now there)

public class MainFrame extends JFrame {
    public static void main(String[] args) {
        new MainFrame();
    }

public MainFrame() {
    setLayout(new GridBagLayout());
    GridBagConstraints c = new GridBagConstraints();
    c.gridx = 0;
    c.gridy = 0;
    c.weightx = 1;
    add(new JPanel(), c);
    c.gridx = 1;
    c.weightx = 0;
    c.anchor = GridBagConstraints.CENTER;
    add(new JButton("Button"), c);
    c.gridx = 2;
    c.weightx = 1;
    c.anchor = GridBagConstraints.WEST;
    add(new JLabel("Label"), c);
    pack();
    setVisible(true);
    setDefaultCloseOperation(EXIT_ON_CLOSE);


   }
}

但是,它产生以下产出,但纽特吨为核心:

就像你一样,可以使用3栏的电网包布。第一和第三列必须具有同等的权重,因此同样如此。中列不会因此坐在中间。我将尝试给你,但我打上“一刀!” HTH

见评论,我对你的样本代码表示怀疑:

public class MainFrame extends JFrame {
    public static void main(String[] args) {
        new MainFrame();
    }

    public MainFrame() {
        setLayout(new GridBagLayout());
        GridBagConstraints c = new GridBagConstraints();
        c.gridx = 0;
        c.gridy = 0;
        c.weightx = 1;
        Component panel = new JPanel();
        panel.setBackground(Color.blue);
        add(panel, c);
        c.gridx = 1;
        c.weightx = 0;
        c.anchor = GridBagConstraints.CENTER;
        add(new JButton("Button"), c);
        c.gridx = 2;
        c.weightx = 1;
        c.anchor = GridBagConstraints.WEST;
        JLabel label = new JLabel("Label");
        add(label, c);

        panel.setPreferredSize(label.getPreferredSize());

        pack();
        setVisible(true);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
    }
}

Answer

使用支持你需要的“LayoutManager”是前进的道路。高层管理人员可以确定(一栏/行)大小到相等的宽度/宽度的群体。如果核心管理人员不允许这种调制性规范,则由第三方管理人负责,即:MigLayout、 FormLayout或设计GridLayout。在学习方面投入的时间是:

在MigLayout(目前为男性个人利益),反政府分子是“集体团体Name”或“sg groupName”(如果只有集团成员,Name可以空出)。

    JButton button = new JButton("somesize");
    JLabel label = new JLabel("--outer--");
    MigLayout layout = new MigLayout("debug, wrap 3", 
           "[sizegroup, grow][center][sizegroup, grow]");
    JComponent comp = new JPanel(layout);
    // start adding component in second column 
    comp.add(button, "cell 1 0");
    comp.add(label);
    // add something spanning all column in second row for comparison
    comp.add(new JButton("somesize"), "span 3, center");
