TextArea


The TextArea control in AWT provide us multiline editor area. The user can type here as much as he wants. When the text in the text area become larger than the viewable area the scroll bar is automatically appears which help us to scroll the text up & down and right & left.

Syntax:
public class TextArea
   extends TextComponent


Example:

  private void showTextAreaDemo(){
   headerLabel.setText("Control in action: TextArea"); 
      Label  commentlabel= new Label("Comments: ", Label.RIGHT);
      final TextArea commentTextArea = new TextArea("This is a AWT tutorial "
      +"to make GUI application in Java.",5,30);
     Button showButton = new Button("Show");
      showButton.addActionListener(new ActionListener() {
         public void actionPerformed(ActionEvent e) {     
            statusLabel.setText( commentTextArea.getText());        
         }
      }); 

      controlPanel.add(commentlabel);
      controlPanel.add(commentTextArea);        
      controlPanel.add(showButton);
      mainFrame.setVisible(true);  
   }
}
