I have been given the assignment to do the following:

Create a class called DrawImageControlPanel. Modify the code presented in the Module 5 slides (also posted separately on the Resources page) such that this new JPanel is integrated as part of the application. You are integrating the new functionality, not replacing!

Add a menu item named Show Picture to the File menu that will show the image of a Picture object. This image should be displayed within the new JPanel. To do this, look for a method that allows you to get the image from the Picture object. When that menu item is selected another menu named Image should be displayed that allows image manipulation operations to be performed. Support at least two image manipulation operations. These can be the same operations that you have used previously, or they can be new ones.

Add another menu item to the File menu that "loads" a Sound object. When that menu item is selected another menu named Sound should be displayed that allows sound operations to be performed. Support at least two sound operations. The first operation is to play the sound. The second operation is to play the mirror of the sound.

Add one more feature, for example a new image operation or a new sound operation. You will need to add at least one additional menu item to the Image or Sound menu to allow for the selection of this additional operation. If it makes sense, given the feature you are adding, you may want to add an additional menu item to the File menu as well.

If I could just edit the ControlFrame.java file I think I could at least get started, but my understanding is that I am to use the new DrawImageControlPanel.java file to put my code in using composition. Can you please help me get started by adding an item to the file menu? Below are the files:

File ControlFrame.java:

calcPanel.add( xValTextField );

yValTextField = new JTextField( 3 ); yValTextField.addActionListener( new ActionListener() { public void actionPerformed( ActionEvent event ) { yStr = event.getActionCommand(); } } );

calcPanel.add( yValTextField ); calcJButton = new JButton( "Calculate" ); calcJButton.addActionListener( new ActionListener() { public void actionPerformed( ActionEvent event ) { try { int x = Integer.parseInt( xStr ); int y = Integer.parseInt( yStr ); int result = x + y; calcJLabel.setText(xStr + " + " + yStr + " = " + result); } catch (NumberFormatException e) { JOptionPane.showMessageDialog( ControlFrame.this, "You must enter a valid number and then for each textbox!", "Invalid Input", JOptionPane.ERROR_MESSAGE ); e.printStackTrace(); } } } ); calcPanel.add( calcJButton ); calcJLabel = new JLabel(); calcPanel.add( calcJLabel, BorderLayout.CENTER ); setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );

setSize( 200, 250 ); setVisible( true ); validate(); } }
