我如何做擺動複雜佈局Java

Question

我需要關於java swing佈局的幫助。我想要做這樣的任何事物（請參見圖片）：

我試圖把網格包佈局，但我不能與內容10:00（上圖）插入floatting的JPanel。任何人都可以幫助我？

Answer 1

在大多數情況下，你通常需要考慮使用多個佈局，但在你的情況下，GridBagLayout應該是能夠實現你想要的基本佈局

對於需要拓展多列組件，您可以使用GridBagConstraints#gridwidth，同樣，對於需要擴展多行GridBagConstraints#gridheight

作爲一個整體，打破你佈局的要求爲職責的各個領域，例如，記分卡他們的自我，有自己的佈局要求，並應組件是自包含的組件，這將減少佈局的複雜性。

你可以做一個容器中的（核心）的佈局，但實在是太大了容易折斷，相反，你應該嘗試向下突破UI段...

這些都是，兩個核心部分，我看到的，也有在其中小節，但是這是我一開始...
