java - 为什么 GridBagLayout 会提供奇怪的结果？

Question

我希望各种组件展开并填满整个窗口。

您尝试过其他方法吗？ 是的，我尝试过 GridLayout，但按钮看起来很大。我还尝试了 pack() ，它使窗口变小了。窗口应为 750x750 :)

我正在尝试的是:

这4个按钮在上面呈细条状

带有 JPanels 的滚动 Pane 将包含所有视频转换任务。这样占用空间最大

底部的 JPanel 包含作为细条的 JProgressBar。

但是好像哪里出了问题。 请帮我解决这个问题

使用这个

gbc.weightx = 1;
gbc.weighty = 1;
gbc.fill = GridbagConstraints.BOTH
