Examples of java.awt.GridLayout

java.awt.GridLayout
The GridLayout class is a layout manager that lays out a container's components in a rectangular grid. The container is divided into equal-sized rectangles, and one component is placed in each rectangle. For example, the following is an applet that lays out six buttons into three rows and two columns:
```
 import java.awt.*; import java.applet.Applet; public class ButtonGrid extends Applet { public void init() { setLayout(new GridLayout(3,2)); add(new Button("1")); add(new Button("2")); add(new Button("3")); add(new Button("4")); add(new Button("5")); add(new Button("6")); } } 
```
If the container's ComponentOrientation property is horizontal and left-to-right, the above example produces the output shown in Figure 1. If the container's ComponentOrientation property is horizontal and right-to-left, the example produces the output shown in Figure 2.

Figure 1: Horizontal, Left-to-Right Figure 2: Horizontal, Right-to-Left

When both the number of rows and the number of columns have been set to non-zero values, either by a constructor or by the setRows and setColumns methods, the number of columns specified is ignored. Instead, the number of columns is determined from the specified number of rows and the total number of components in the layout. So, for example, if three rows and two columns have been specified and nine components are added to the layout, they will be displayed as three rows of three columns. Specifying the number of columns affects the layout only when the number of rows is set to zero. @version 1.42, 11/17/05 @author Arthur van Hoff @since JDK1.0
