The following link might help you to choose the most appropriate layout for your needs. Its the Java Tutorial called "A Visual Guide to Layout Manager", which shows nice pictures of each layout and what they look like...
以下链接可能会帮助您选择最适合您需要的布局。它的 Java 教程称为“布局管理器的可视化指南”，其中显示了每个布局的精美图片及其外观......

Otherwise, if you say GridLayoutis similar to what you need, you could always write your own MyGridLayoutclass (that extends GridLayout) and overwrite the method that does the autoresizing.
否则，如果您说GridLayout的与您需要的相似，您始终可以编写自己的MyGridLayout类（即扩展类GridLayout）并覆盖执行自动调整大小的方法。

Just Override preferredLayoutSize() in flowlayout and set Maximum size to it. set Alignment as LEADING and set it to your JPanel. You'll get what you want
只需覆盖 flowlayout 中的 preferredLayoutSize() 并将最大大小设置为它。将 Alignment 设置为 LEADING 并将其设置为您的 JPanel。你会得到你想要的
private FlowLayout getFlowLayout(int maximumSize)
{
if (flowLayout == null)
{
flowLayout = new FlowLayout()
{
@Override
public Dimension preferredLayoutSize(Container target)
{
Dimension dimension = super.preferredLayoutSize(target);
dimension.width = Math.min(maximumSize, dimension.width);
return dimension;
}
};
flowLayout.setAlignment(FlowLayout.LEADING);
}
return flowLayout;
}
