如何使用 MiGLayout 将组件置于包含多个组件的行上居中

我大约一个半月前开始使用 MiGLayout，一切都很简单，而且效果很好。只有一个问题我仍然无法解决。

假设我想要一行最右侧有两个按钮和一个居中标题，当我这样做时，标题实际上并没有居中：（

“this”是一个 JPanel）

this.add(labelTitle, "split, span, center");
this.add(closeButton, "east");
this.add(mainMenuButton, "east");

会发生什么“labelTitle”在放置按钮后的剩余可用空间中居中，但我实际上希望它相对于整个 JPanel 居中，而不仅仅是剩余空间。

我可以使用哪些参数来获得所需的效果？我知道我可以使用绝对定位，但我不想这样做，因为在我的例子中，它首先违背了使用 MiGLayout 的目的。

I started using MiGLayout about a month and half ago and everything is simple and works great. There's only one issue I still have that I haven't been able to fix.

Let's say I want to have a row that has two buttons on the right-most side and a centered title, the title doesn't actually get centered when I do it this way:

("this" is a JPanel)

this.add(labelTitle, "split, span, center");
this.add(closeButton, "east");
this.add(mainMenuButton, "east");

What happens is that "labelTitle" is centered in the remaining space available after the buttons are placed, but I actually want it to be centered relative to the whole JPanel, not just the remaining space.

What parameters could I use to get the desired effect? I know I could use absolute positioning, but I don't want to do that because it defeats the purpose of using MiGLayout in the first place in my case.

您正在寻找这样的东西吗？

干杯!

public static void main(String[] args)
{
    JFrame frame = new JFrame();

    JPanel panel = new JPanel(new MigLayout("debug"));
    panel.add(new JLabel("Label Title"), "x2 min(b1.x - unrel, (container.w+pref)/2)");
    panel.add(new JButton("Close Button"), "id b1, pushx, alignx right");
    panel.add(new JButton("Main Menu Button"), "alignx right");

    frame.add(panel);
    frame.setSize(800, 200);
    frame.setLocationRelativeTo(null);
    frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    frame.setVisible(true);
}

Can it be something like this you are looking for?

Cheers!

您可以使用 JXLayer 并将按钮放在玻璃窗格中。

JButton closeButton = new JButton("Close");
JButton mainMenuButton = new JButton("Menu");
JLabel labelTitle = new JLabel("Application");

JPanel panel = new JPanel();
panel.setLayout(new MigLayout(new LC().fillX()));
panel.add(labelTitle, new CC().alignX("center").spanX());

JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(new MigLayout(new LC().fillX()));
buttonPanel.add(closeButton, new CC().alignX("right").split());
buttonPanel.add(mainMenuButton, new CC().alignX("right"));
buttonPanel.setOpaque(false);

JXLayer<JPanel> mainPanel = new JXLayer<JPanel>();
mainPanel.setView(panel);
mainPanel.setGlassPane(buttonPanel);

JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setContentPane(mainPanel);
frame.setSize(400, 600);
frame.setVisible(true);

You can use the JXLayer and put the buttons in the glasspane.

JButton closeButton = new JButton("Close");
JButton mainMenuButton = new JButton("Menu");
JLabel labelTitle = new JLabel("Application");

JPanel panel = new JPanel();
panel.setLayout(new MigLayout(new LC().fillX()));
panel.add(labelTitle, new CC().alignX("center").spanX());

JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(new MigLayout(new LC().fillX()));
buttonPanel.add(closeButton, new CC().alignX("right").split());
buttonPanel.add(mainMenuButton, new CC().alignX("right"));
buttonPanel.setOpaque(false);

JXLayer<JPanel> mainPanel = new JXLayer<JPanel>();
mainPanel.setView(panel);
mainPanel.setGlassPane(buttonPanel);

JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setContentPane(mainPanel);
frame.setSize(400, 600);
frame.setVisible(true);
