Create a Container example

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 Frame and a new Panel wich will play the role of the Container.
• You can the use the Panel.add method 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);

  }

}
