hiding title bar of JInternalFrame? -java
提问by Tushar Chutani
I found some code online, I edited it a bit. I want to hide title bar of a JInternalFrame.
我在网上找到了一些代码，我编辑了一下。我想隐藏 JInternalFrame 的标题栏。
JInternalFrame frame = new JInternalFrame();
// Get the title bar and set it to null
setRootPaneCheckingEnabled(false);
javax.swing.plaf.InternalFrameUI ifu= frame.getUI();
((javax.swing.plaf.basic.BasicInternalFrameUI)ifu).setNorthPane(null);
frame.setLocation(i*50+10, i*50+10);
frame.setSize(200, 150);
//frame.setBackground(Color.white);
frame.setVisible(true);
desktop.add(frame);
The problem is that the title bar isn't being hidden for some reason. Thanks.
问题是标题栏由于某种原因没有被隐藏。谢谢。

First convert the internalframe to basicinternalframe.
首先将内部框架转换为基本内部框架。
do it like this:-
像这样做：-
BasicInternalFrameUI bi = (BasicInternalFrameUI)your_internalframe_object.getUI();
bi.setNorthPane(null);
After this your title bar will be invisible.
在此之后，您的标题栏将不可见。

I solved this problem this way: I subclass JInternalFrameand add the following code to its constructor. (I get the subclassing for free because I use netBeans' GUI Builder)
我通过这种方式解决了这个问题：我继承了 JInternalFrame并将以下代码添加到它的构造函数中。（我免费获得子类，因为我使用了 netBeans 的 GUI Builder）
((javax.swing.plaf.basic.BasicInternalFrameUI)this.getUI()).setNorthPane(null);
in your case I think
在你的情况下，我认为

for me this works very well:
对我来说，这很有效：
putClientProperty("JInternalFrame.isPalette", Boolean.TRUE);
getRootPane().setWindowDecorationStyle(JRootPane.NONE);
((BasicInternalFrameUI) this.getUI()).setNorthPane(null);
this.setBorder(null);
thanks.
谢谢。

What the others say. Depending on the framework the ui might get updated though, which will make it reappear. So for me it worked initializing the JInternalFramelike this:
别人怎么说。根据框架，ui 可能会更新，这将使其重新出现。所以对我来说，它像这样初始化JInternalFrame：
JInternalFrame internalFrame = new JInternalFrame() {
@Override
public void setUI(InternalFrameUI ui) {
super.setUI(ui); // this gets called internally when updating the ui and makes the northPane reappear
BasicInternalFrameUI frameUI = (BasicInternalFrameUI) getUI(); // so...
if (frameUI != null) frameUI.setNorthPane(null); // lets get rid of it
}
};
