MigLayout面板在MigLayout面板中-将其与底部对齐

Question

​

​

面板右边有所有的按钮，我想对齐到底部。

JPanel easternDock = new JPanel(new MigLayout("", ""));
easternDock.add(button1, "wrap");
....
this.add(easternDock);

我在想，我可以在所有按钮之上添加一个组件，并使它在y维中增长，以填充屏幕，但我不确定我会为此使用什么组件，而且我也找不到任何设计来实现这种功能的组件。

我这样做的方法是在"easternDock“面板中有另一个面板，该面板包含所有组件，并使用push列/Row约束将另一个面板推到底部。

“：：push”(或者"push“，如果与默认的间隙大小一起使用)可以添加到间隙大小中，使间隙变得贪婪，并且尽量占用空间，而不使布局比容器大。

下面是一个示例：

public class AlignToBottom {

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

    // Settings for the Frame
    frame.setSize(400, 400);
    frame.setLayout(new MigLayout(""));
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    // Parent panel which contains the panel to be docked east
    JPanel parentPanel = new JPanel(new MigLayout("", "[grow]", "[grow]"));

    // This is the panel which is docked east, it contains the panel (bottomPanel) with all the components
    // debug outlines the component (blue) , the cell (red) and the components within it (blue)
    JPanel easternDock = new JPanel(new MigLayout("debug, insets 0", "", "push[]")); 

    // Panel that contains all the components
    JPanel bottomPanel = new JPanel(new MigLayout());


    bottomPanel.add(new JButton("Button 1"), "wrap");
    bottomPanel.add(new JButton("Button 2"), "wrap");
    bottomPanel.add(new JButton("Button 3"), "wrap");

    easternDock.add(bottomPanel, "");

    parentPanel.add(easternDock, "east");

    frame.add(parentPanel, "push, grow");
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);

}

}
