类名称：FlowLayout

FlowLayout介绍

[英]A flow layout arranges components in a left-to-right flow, much like lines of text in a paragraph. Flow layouts are typically used to arrange buttons in a panel. It will arrange buttons left to right until no more buttons fit on the same line. Each line is centered.

For example, the following picture shows an applet using the flow layout manager (its default layout manager) to position three buttons:

Here is the code for this applet:

Note: The following code example includes classes that do not appear in this specification. Their inclusion is purely to serve as a demonstration.

import java.awt.*;  
import java.applet.Applet; 
public class myButtons extends Applet { 
Button button1, button2, button3; 
public void init() { 
button1 = new Button("Ok"); 
button2 = new Button("Open"); 
button3 = new Button("Close"); 
add(button1); 
add(button2); 
add(button3); 
} 
}

A flow layout lets each component assume its natural (preferred) size.
[中]流程布局以从左到右的流程排列组件，非常类似于段落中的文本行。流程布局通常用于在面板中排列按钮。它将从左到右排列按钮，直到同一行上没有更多的按钮。每条线都居中。
例如，下图显示了一个小程序使用流布局管理器（其默认布局管理器）定位三个按钮：
以下是此小程序的代码：
注意：下面的代码示例包括本规范中未出现的类。他们的加入纯粹是为了证明

import java.awt.*;  
import java.applet.Applet; 
public class myButtons extends Applet { 
Button button1, button2, button3; 
public void init() { 
button1 = new Button("Ok"); 
button2 = new Button("Open"); 
button3 = new Button("Close"); 
add(button1); 
add(button2); 
add(button3); 
} 
}

流布局允许每个组件假定其自然（首选）大小。
