隐藏 JInternalFrame 的标题栏?-java

2022-01-24 00:00:00 user-interface java swing jframe 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.

I found some code online, I edited it a bit. I want to hide title bar of a JInternalFrame.

  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);

问题是标题栏由于某种原因没有被隐藏.谢谢.

The problem is that the title bar isn't being hidden for some reason. Thanks.

推荐答案

我这样解决了这个问题:我继承了 JInternalFrame 并将以下代码添加到它的构造函数中.(我免费获得子类化，因为我使用 netBeans 的 GUI Builder)

I solved this problem this way: I subclass JInternalFrame and add the following code to its constructor. (I get the subclassing for free because I use netBeans' GUI Builder) 

((javax.swing.plaf.basic.BasicInternalFrameUI)this.getUI()).setNorthPane(null);

我认为你的情况
