Inputting some text in a GUI.

[AJArmstron@aol.com]

Hello. I am new to Java and am finding it difficult to grasp the GUI aspect.

What I want to do is to have some kind of input box where the user enters some text and then presses a button which processes the text (using a class that I have developed).

I don't have a clue as to how I should go about creating this input box. i would be very grateful if someone could give some suggestions as to the best way to create this input box?

Many thanks

JOptionPane comes to mind, but what you really must do is to study the Swing tutorials: Swing Tutorials

Much luck!

i wrote some code. I think that is what you are looking for.

import javax.swing.JTextArea;
import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;

public class CreateInputBoxExample {
	MyPanel panel = new MyPanel();
	JFrame frame = new JFrame("my frame");
	
	public void createAndShowGUI() {
		frame.add(panel);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setSize(300,300);
		frame.setLocation(100,100);
		frame.setVisible(true);
	}
	
	public static void main(String[] args) {
		SwingUtilities.invokeLater(new Runnable() {
			public void run() {
				CreateInputBoxExample createInputBox = new CreateInputBoxExample();
				createInputBox.createAndShowGUI();
			}
		});
	}

}

class MyPanel extends JPanel { 
	MyPanel() {
		JTextArea textArea = new JTextArea(numberOfColumns, numberOfRows);
		JButton processButton = new JButton("process the text");

		add(textArea);
		add(processButton);
	}
	public static final int numberOfColumns = 10;
	public static final int numberOfRows = 20;
}

Thank you very much for both of your replies. I really appreciated the time and quality of both posts.

I have spent sometime using the JOptionPane which works very nicely and the coding is simple.

I have also copied and pasted the coding from the last post which perhaps produces a more impressive text box as well as demonstrates using more complicated coding. However, I would be grateful if someone could tell me what variable (field) the text that has been input is stored (so that I can process it)?

Many thanks!

textArea.getText()

Thank you!

Concerning the comment use "textArea.getText() ".

Do I need to write a procedure to getText() ?

Also if you are using a textfield would the code become textField.getText()??
