我怎么做摆动复杂的布局Java

Question

我需要有关java swing布局的帮助。我想做任何类似的事情（请看图片）：

我尝试了一个网格包布局，但我无法插入内容为10:00的浮动JPanel（在图像上）。有人可以帮帮我吗？

在大多数情况下，您通常需要考虑使用多个布局，但在您的情况下，GridBagLayout应该能够实现您对基本布局的要求

对于需要展开多列的组件，您可以使用GridBagConstraints#gridwidth同样适用于需要展开多行的组件GridBagConstraints#gridheight

作为一个整体，将布局要求分解为各个责任区域，例如，记分卡本身就有自己的布局要求，应该是自包含的组件，这会降低布局的复杂性。

你可以在单个容器中进行（核心）布局，但这很容易破解，相反，你应该尝试将UI分解成各个部分......

这是我看到的两个核心部分，其中有子部分，但这是我开始的地方......
