抱歉打扰，但我正在尝试编写一个“交互式元素周期表”，并且我想在所有元素的 block 下添加一个 JSlider:
这是我的代码(没有 JSlider)

对所有代码感到抱歉，只是不想错过任何内容。
无论如何，我想在所有盒子下面制作一个 JSlider，所以它看起来像这样:
[][][][][][] (blocks)
[][][][][][] (blocks)
[][][][][][] (blocks)
------------ (slider)
我想将 JSlider 添加到 Pane 中，但每当我这样做时，它只会将 JSlider 放入 1 个网格(在网格布局中)
非常感谢您的宝贵时间:)
任何帮助将不胜感激!
最佳答案
利用多种布局。使用 GridLayout...
public PeriodicTable(int rows, int columns) {
final Container pane = new JPanel();
pane.setLayout(new GridLayout(rows, columns));
然后利用框架的(默认)BorderLayout 添加它和 slider
getContentPane().add(pane);
JSlider slider = new JSlider();
getContentPane().add(slider, BorderLayout.SOUTH);
这是一种非常常见且强大的 UI 设计方法，您应该习惯使用它;)
关于java - 将 JSlider 添加到具有 GridLayout 的 JFrame (Java)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31172692/
