The Java Applet wizard is divided into the following steps:

1. Describe the applet class for the Java applet.

2. Specify an HTML page for the Java applet. (optional)

3. Create parameters for the Java applet.

4. Provide additional information for the Java applet.

To use the Java Applet wizard, follow these steps:

1. Describe the applet class for the Java applet.

This section of the wizard, shown in Figure 12.4, lets you specify the class name, package name, and location for the new applet. Other options are available to further describe the applet.

This section includes the following parts:

• Class Name
• Package Name
• Location
• Can run as a standalone application
• Generate standard methods
• Generate HTML Page
• Choose from this pop-up menu the desired base-class applet type. You can choose AWT applet or Swing applet.
• Choose from this pop-up menu the desired base-class applet type. You can choose AWT applet or Swing applet.
Java Applet wizard - Applet Class:

Enter a name for the applet's class in this field. An example name is provided.

If you wish, you can enter in this field a package for the applet class. A sample package name is provided.

In this field, type a location in which to save the applet class for the new applet. Alternatively, click the button next to the field. A standard window displays. Use the window controls to select a location. Note that a valid location depends on your settings for strict filenames and strict package roots.

Enable this checkbox if you want the new applet to operate without needing to be called from another application. Disable this checkbox otherwise.

Enable this checkbox if you want the new applet to generate standard methods for its interface, such as show() and dispose(). Disable this checkbox otherwise.

Enable this checkbox if you want to create an HTML page to help you test the new applet. Disable this checkbox otherwise. Note that the Java Applet wizard displays the HTML Page section only when you enable the Generate HTML Page checkbox. This checkbox is enabled by default.

Choose from this pop-up menu the desired base-class applet type. You can choose AWT applet or Swing applet.

2. Specify an HTML page for the Java applet. (optional)

This section of the wizard, shown in Figure 12.5, is displayed only when you enable the Generate HTML Page checkbox from the previous section. The HTML Page section lets you define a Hypertext Markup Language (HTML) page to test the new applet.

This section includes the following parts:

• Title
• Applet Name
• Codebase/Archive
• Use Archive (JAR)
• Width
• Height
• HSpace
• VSpace
• Align

Enter in this field a title for the HTML page you wish to generate. An example title is provided.

Your HTML browser displays messages about the applet by using the name you type in this field. A sample applet name is shown.

If desired, use this field to specify a codebase or archive for use with the new applet. An example is shown.

Enable this checkbox if you want to use a Java archive (JAR) with the new applet. If this checkbox is enabled, a ".jar" extension is appended to the name in the Codebase/Archive field.

The number you type in this field represents the number of pixels that span the width of the applet within the HTML page.

The number typed in this field specifies the number of pixels that span the height of the applet within the HTML page.

The number in this field defines the number of pixels placed on the left side and on the right side of the applet within the HTML page.

The number in this field defines the number of pixels placed above and below the applet within the HTML page.

Use this pop-up menu to determine the alignment of the applet within the HTML page:

• absbottom-position at the absolute bottom of the page
• absmiddle-position at the absolute middle of the page
• baseline-position at the baseline of the page
• bottom-position at the bottom of the page
• left-position at the left side of the page
• middle-position at the middle of the page. This is the default option.
• right-position at the right side of the page
• texttop-position at the top of the text on the page
• top-position at the top of the page

3. Create parameters for the Java applet.

This section of the wizard, shown in Figure 12.6, lets you create a set of parameters for the new applet. Each parameter has the following fields:

A sample <New> parameter is ready for you to modify. To change a particular field, double-click it, enter a new value, and press Enter/Return to confirm your changes.

When you double-click the Type field, choose a new value from the pop-up menu that appears inside the field. Alternatively, use the keyboard in one of the following ways:

• Choose via data-type name-Repeatedly type the first letter of the data type you wish to choose until the desired data type appears in the field, then press Enter/Return. The matching data types appear in the order listed in the pop-up menu.
• Choose via arrow keys-Press the Down Arrow key or Right Arrow key to choose the subsequent data type in the order listed in the pop-up menu. Press the Up Arrow key or Left Arrow key to choose the previous data type in the order listed in the pop-up menu. Press Enter/Return when the desired data type appears in the field.

To add another parameter to the applet, click Add. The wizard creates a <New> parameter for you to modify. To remove a particular parameter, select one of its fields and click Remove.

4. Provide additional information for the Java applet.

This section of the wizard, shown in Figure 12.7, lets you provide additional information to describe the applet.

This section includes the following parts:

If desired, enter a title for the new applet in this field.

If you wish, type a description for the new applet in this field.

To add the information contained in the Applet title and Description fields to the beginning of every applet file, enable this checkbox. Disable the checkbox otherwise. The checkbox is enabled by default.
