Here's a snapshot of an application that uses aGridLayout
.
You can run GridLayoutDemo using JavaTM Web Start. Its code is in GridLayoutDemo.java
.A
GridLayout
places components in a grid of cells. Each component takes all the available space within its cell, and each cell is exactly the same size. If you resize the GridLayoutDemo window, you'll see that theGridLayout
changes the cell size so that the cells are as large as possible, given the space available to the container.Below is the code that creates the
GridLayout
and the components it manages. You can find the whole program inGridLayoutDemo.java
.The constructor tells thepane.setLayout(new GridLayout(0,2)); pane.add(new JButton("Button 1")); pane.add(new JButton("Button 2")); pane.add(new JButton("Button 3")); pane.add(new JButton("Long-Named Button 4")); pane.add(new JButton("5"));GridLayout
class to create an instance that has two columns and as many rows as necessary.
[PENDING: This section will be converted to present its information in an API table.]The
GridLayout
class has two constructors:At least one of thepublic GridLayout(int rows, int columns) public GridLayout(int rows, int columns, int horizontalGap, int verticalGap)rows
andcolumns
arguments must be nonzero; therows
argument has precedence over thecolumns
argument. ThehorizontalGap
andverticalGap
arguments to the second constructor allow you to specify the number of pixels between cells. If you don't specify gaps, their values default to zero.
The following table lists some of the examples that use grid layout.
Example Where Described Notes GridLayoutDemo
This page Uses a 2-column grid. ComboBoxDemo2
How to Use Combo Boxes One of many examples that use a 1x1 grid to make a component as large as possible. LabelDemo
How to Use Labels Uses a 3-row grid. DragPictureDemo
How to Use Drag and Drop and Data Transfer Uses a 4-row grid to present 12 components that display photographs.
