With this tutorial we shall show you how to create a Container in a Java Desktop Application. The Container component in a very important one because it gives you the ability to organize and group together the components you want.
In short in order to create a Component in a Java Desktop Application, one should follow these steps:
- Create a new
Frameand a newPanelwich will play the role of theContainer. - You can the use the
Panel.addmethod to add the Components you want with the oriantation and to the position you want.
Let’s see the code:
package com.javacodegeeks.snippets.desktop;
import java.awt.BorderLayout;
import java.awt.Button;
import java.awt.Component;
import java.awt.Frame;
import java.awt.Panel;
import java.awt.TextArea;
public class CreateContainerExample {
public static void main(String[] args) {
// Create a frame
Frame frame = new Frame("Example Frame");
/*
* Create a container with a flow layout, which arranges its children
* horizontally and center aligned.
* A container can also be created with a specific layout using
* Panel(LayoutManager) constructor, e.g.
* Panel(new FlowLayout(FlowLayout.RIGHT)) for right alignment
*/
Panel panel = new Panel();
// Add several buttons to the container
panel.add(new Button("Button_A"));
panel.add(new Button("Button_B"));
panel.add(new Button("Button_C"));
// Add a text area in the center of the frame
Component textArea = new TextArea("This is a sample text...");
frame.add(textArea, BorderLayout.CENTER);
// Add the container to the bottom of the frame
frame.add(panel, BorderLayout.SOUTH);
// Display the frame
int frameWidth = 300;
int frameHeight = 300;
frame.setSize(frameWidth, frameHeight);
frame.setVisible(true);
}
}
This was an example on how to create a Container.
