I used a combination of modifiers, the Ctrl and Alt keys, for the accelerators for the Color menu item
actions. This enables me to retain R, G, and B as the letters in the key combinations to set the corres-
ponding colors.
Now you can implement the methods that create the menus, starting with the createFileMenu() meth-
od:

private void createFileMenu() {
JMenu fileMenu = new JMenu("File"); // Create File menu

fileMenu.setMnemonic('F'); // Create shortcut

createFileMenuActions(); // Create Actions for

File menu items

// Construct the file drop-down menu
fileMenu.add(newAction); // New Sketch menu

item

fileMenu.add(openAction); // Open sketch menu

item

fileMenu.add(closeAction); // Close sketch menu

item

fileMenu.addSeparator(); // Add separator

fileMenu.add(saveAction); // Save sketch to

file

fileMenu.add(saveAsAction); // Save As menu item

fileMenu.addSeparator(); // Add separator

fileMenu.add(printAction); // Print sketch menu

item

fileMenu.addSeparator(); // Add separator

fileMenu.add(exitAction); // Print sketch menu

item

menuBar.add(fileMenu); // Add the file menu

}
