我想将两个jPanel并排添加到JFrame中。两个框是jpanels，外框是jframe

I want to add two jPanels to a JFrame side by side. the two boxes are jpanels and the outer box is a jframe

我有这些代码行。我有一个名为seatinPanel的类，它扩展了JPanel，在这个类中我有一个构造函数和一个名为utilityButtons的方法，它返回一个JPanel对象。我希望utilityButtons JPanel在右侧。我这里的代码只在运行时显示utillityButtons JPanel。

I have these lines of code. I have one class called seatinPanel that extends JPanel and inside this class I have a constructor and one method called utilityButtons that return a JPanel object. I want the utilityButtons JPanel to be on the right side. the code I have here only displays the utillityButtons JPanel when it runs.

public guiCreator() { setTitle("Passenger Seats"); //setSize(500, 600); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Container contentPane = getContentPane(); seatingPanel seatingPanel1 = new seatingPanel();//need to declare it here separately so we can add the utilityButtons contentPane.add(seatingPanel1); //adding the seats contentPane.add(seatingPanel1.utilityButtons());//adding the utility buttons pack();//Causes this Window to be sized to fit the preferred size and layouts of its subcomponents setVisible(true); }

推荐答案

最灵活的LayoutManager我会推荐是 BoxLayout 。

The most flexible LayoutManager I would recommend is BoxLayout.

您可以执行以下操作：

JPanel container = new JPanel(); container.setLayout(new BoxLayout(container, BoxLayout.X_AXIS)); JPanel panel1 = new JPanel(); JPanel panel2 = new JPanel(); //panel1.set[Preferred/Maximum/Minimum]Size() container.add(panel1); container.add(panel2);

然后将容器添加到框架组件的对象。

then add container to object to your frame component.
