我在JTabbedPane框中有一个JDialog，在该窗格中包含的所有GridBagLayout上使用JPanels。在显示的第一个面板上有一个JTextArea（descTxt），可以输入电影描述。当您在JTextArea中输入大量文本时，它似乎很好单击面板上任何不是组件（空灰色空间）的任何位置，然后所有文本字段和文本窗格缩小到大小为0的位置。
以下是要粘贴和测试的示例文本：
在对火星的载人飞行任务中，宇航员马克沃特尼被假定为 在一场猛烈的风暴之后死去，并被他的船员留下。但沃特尼有 幸存下来，发现自己被困在敌对的星球上。 只有微薄的供应，他必须利用他的聪明才智，机智和 精神生存并找到一种方式向地球发出信号表明他还活着。
这是我的代码的可运行示例：

请帮忙。这个非常令人困惑，我似乎无法在任何地方找到解决方案。
答案 0 :(得分：1)
所以，问题似乎是setResizable(false)和ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED的组合（好吧，我只是讨厌不可见的窗口）。
当您填写JTextArea时，它会将JScrollPane“添加”到已经“打包”的窗口中，因此组件的大小已经更改，然后当容器重新生效时，那里会发生什么已经不再有足够的空间将所有字段打包成其首选大小，因此它们的大小已经调整为最小尺寸，通常为0x0或足够近。
您可以采取一些措施来帮助解决问题。您可以使用GridBagConstraints#fill并使用GridBagConstraints.HORIZONTAL作为文本字段，使用GridBagConstraints.BOTH作为文本区域，这将允许字段“填充”并占用列的可用空间/ row，无论单元格空间何时小于组件的首选大小。
您可能还会发现GridBagConstraints#weightx/y 1可以提供帮助。
如果您遇到麻烦，可以在ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS中使用JScrollPane，虽然不是很漂亮，但会在JScrollBar大小中添加JScrollPane当窗口打包时
<强>更新
所以，基本上，我最终使用fill和weightx/y的组合来JScrollPane和JTextArea s
g1.fill = GridBagConstraints.BOTH;
g1.weightx = 1;
g1.weighty = 1;
adminPanel1.add(descTxtPane, g1);
g1.fill = GridBagConstraints.NONE;
g1.weightx = 0;
g1.weighty = 0;
对于JTextField我刚刚使用的fill似乎已经稳定了......
g1.fill = GridBagConstraints.HORIZONTAL;
adminPanel1.add(idTxt, g1);
g1.fill = GridBagConstraints.NONE;
这导致类似......
