Java JFreeChart隐藏在另一个后面

我试图在IntelliJ中构建UI，但这很难，所以我尝试在Eclipse中构建它。现在UI看起来稍微好一点，但仍然很差。图中的一个（塞纳一号）应该更大，南部的第二个应该更小，但平坦而长。我试着使用预先指定的大小或验证或重新绘制，但仍然一无所获。如何将它们锚定在侧边边界上，并避免自己覆盖它们

由于您的代码不正确，我无法对其进行更改，但我认为您的问题在于布局设置不正确。例如，创建一个新的

JPanel

：

JPanel jpSouth = new JPanel();
FlowLayout flowLayout_1 = (FlowLayout) jpSouth.getLayout();
flowLayout_1.setAlignment(FlowLayout.TRAILING);

您知道它正在使用defaul提供的

FlowLayout

，稍后您将使用：

jpSouth.add(jfcPanelSouth,BorderLayout.CENTER);

但您永远不会将布局更改为

边框布局

。不能混合一个特定容器的布局。但这并不是你直接遇到的问题

您的

BorderLayout.SOUTH

区域水平延伸，以适应内部组件，

BorderLayout.CENTER

将所有规格都保留（或不保留）。这就是

BorderLayout

的这些部分的工作原理。所以您可以更改放置特定组件的位置，或者根本更改布局

我建议尝试：

JPanel jpCenter = new JPanel(new BorderLayout());
...
jpCenter.add(jfcPanelCenter,BorderLayout.NORTH);
...
jpCenter.add(jfcPanelSouth,BorderLayout.SOUTH); //not to contentPane!

这将改变一种安排。但是我不确定，这是你想要的吗。如果没有，请尝试使用不同的布局，例如

BoxLayout

。 此外，我宁愿使用

pack（）

设置组件的大小，也不愿在计数器上使用

setBounds

---

如果您想创建GUI，但不关心如何创建，也可以使用GUI构建器，如Netbeans IDE GUI构建器。

您的建议非常有用。在我加入你的建议后，我很快就能解决我的问题了。只有一件事我不明白。为什么现在中面板宽而平，南面板更大。我希望南面板宽而平，中间面板大而主chart@GarryMoveOut我认为这是和以前一样的问题，您仍然将

jpCenter

添加到

contentPane

center，因此它将更改大小以适应左边的规格。然后将

jpSouth

添加到contentPane的南部，使其再次垂直扩展。试着把这两个位置都放进去：

jfcPanelCenter

放在北方位置，

jfcPanelSouth

放在

jpCenter的边界布局的南方位置。
。我按照您的建议更正代码。差不多好了。但是一些jfcPanelSouth
落后于
jfcPalenCenter
@GarryMoveOut可能会尝试使用JFrame.pack（）
