我怎样才能重新排列我的代码以便雨和海报出现
提问于 2016-12-22 06:32:25
在这里，我有一组代码来显示背景下生成的多边形：
public class Drawing extends JFrame{
public static void main(String []args)

}
public Drawing()

//JFrame frame = new JFrame("Poster");
setSize(1180,750);
setLocationRelativeTo(null);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
getContentPane().add(new MyComponent());
setVisible(true);
//background
setLayout(new BorderLayout());
JLabel background=new JLabel(new ImageIcon("J:\\1. Current Works\\CSC533\\1. project 1.0\\bg.jpg"));
add(background);
background.setLayout(new FlowLayout());
}

}我得到的输出如下：
在添加雨效应后，我遇到的问题是，我从雨中调用的面板覆盖了我的背景。我直接实现了雨码，不太明白。我很确定我得在里面换个东西。
问题是，我怎样才能使雨以图片为背景出现。组件/超级英雄可能在雨后或它的前面，无论是容易的。
我希望我已经做了足够的准备，尽管它并不精确，因为我不知道具体的问题。非常感谢!

首先，让您的雨面板扩展JComponent。JPanel有一个不透明的背景，这将掩盖较低的组成部分。
class RPanel extends JComponent {然后将雨面板添加到框架的玻璃板中：
public Drawing() {
final RPanel rPanel = new RPanel();
setSize(1180, 750);
setLocationRelativeTo(null);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
getContentPane().add(new MyComponent());
JPanel glassPane = (JPanel) getGlassPane();
glassPane.setLayout(new BorderLayout());
glassPane.add(rPanel, BorderLayout.CENTER);
glassPane.setVisible(true);
setVisible(true);

首先：
- 在进行自定义绘制时，您应该重写
paintComponent()，而不是super.paintComponent(...)()，然后调用super.paintComponent(...)作为第一个语句。 - 在调用
setVisible(true)之前，应该将所有组件添加到框架中。
然后，您需要了解JFrame的结构。JFrame具有父/子关系。框架的内容窗格是子元素。然后，内容窗格可以有子面板/组件。然后这些面板也可以包含更多的面板/组件。
阅读关于使用顶级容器的Swing教程，以更好地理解这种结构。
getContentPane().add(new MyComponent());
add(rPanel); 以上代码基本相同。也就是说，组件和面板都添加到内容窗格中。没有必要使用getContentPane()。
setLayout(new BorderLayout());添加组件后，不要更改布局。基本上，这将导致前面添加的两个组件被添加到框架中的下一个组件替换。
所以你想要的是这样的结构：
- frame
- content pane
- background
- painting因此，基本的逻辑是：
JLabel background = new JLabel( new BorderLayout() );
background.setLayout( ... ):
add( background );
JComponent painting = new MyComponent();
background.add( painting );
setVisible( true );保持一个链接到Swing教程手边。例如，它也有关于以下内容的章节：
- 自定义绘图-它向您展示了如何覆盖
getPreferredSize()方法。 - 布局管理器-它解释了为什么首选的大小是重要的一些布局管理器。
