PDF-417 2d Barcode Generator In Java
Using Barcode printer for Java Control to generate, create PDF-417 2d barcode image in Java applications.
The NAME property determines the label for the menu item and the button The LONG_DESCRIPTION is not used at present The SMALL_ICON property does work correctly Now we can derive an ExitButton from the ActionButton like this
Paint Barcode In Java
Using Barcode generation for Java Control to generate, create bar code image in Java applications.
public class ExitButton extends ActionButton { JFrame fr; public ExitButton(String caption Icon img) { super(caption, img); } public void actionPerformed(ActionEvent e) { Systemexit(0); } }

Using Barcode recognizer for Java Control to read, scan read, scan image in Java applications.
We do the same for the FileButton, adding these to the toolbar and menu as follows:
PDF 417 Generator In C#.NET
Using Barcode encoder for .NET Control to generate, create PDF-417 2d barcode image in VS .NET applications.
//add the File menu JMenu mFile = new JMenu("File"); mbaradd(mFile); //create two Action Objects Action Open = new FileButton("Open", new ImageIcon("opengif"), this); mFileadd(Open); Action Exit = new ExitButton("Exit", new ImageIcon("exitgif")); mFileaddSeparator(); mFileadd(Exit); //now create a toolbar that fixes up the buttons as you add them toolbar = new JToolBar(); getContentPane()add(jp = new JPanel()); jpsetLayout(new BorderLayout()); jpadd("North", toolbar);

This code produces the program window shown in Figure 301 Figure 301 A menu with pictures using the same Action object as the toolbar buttons
PDF-417 2d Barcode Generator In Visual Basic .NET
Using Barcode generator for .NET Control to generate, create PDF-417 2d barcode image in .NET framework applications.
The problem with this approach is that we don't usually want the images in the menu or the text on the toolbar However, the add methods of the toolbar and menu have a unique feature when used to add an action object: They return an object of type JButton or JMenuItem, respectively We can use these to set the features the way that we want them For the menu, we want to remove the icon
EAN128 Generator In Java

Design Patterns in the Action Object
Planet Creator In Java
Using Barcode printer for Java Control to generate, create USPS PLANET Barcode image in Java applications.
Objects that implement the Action interface deserve discussion because they exemplify at least two design patterns First, each Action object must have its own actionListener method and thus can directly launch the code to respond to that action In addition, even though these Action objects might have two (or more) visual instantiations, they provide a single point that launches this code This is an excellent example of the Command pattern In addition, the Action object takes on different visual aspects depending on whether it is added to a menu or to a toolbar In fact, you could decide that the Action object is a Factory pattern, which produces a button or menu object depending on where it is added It does seem to be a Factory because the toolbar and menu add methods return instances on those objects On the other hand, the Action object seems to be a single object and gives different appearances depending on its environment This is a description of the State pattern, according to which an object seems to change class (or methods) depending on the object's internal state One interesting and challenging aspect of the design patterns discussed in this book is that once you start looking at a pattern, you discover that it is represented far more widely that you first assumed In some cases, the application and implementation are obvious; in other cases, the implementation is more subtle In these cases, you step back, tilt your head, squint, and realize that from that angle it looks like a pattern where you hadn't noticed one before Again, being able to label the code as exemplifying a pattern makes it easier for you to remember how it works and easier for you to communicate to others how that code is constructed
