Rogue Wave JViews TGO Sample: Equipment Component - Custom Classes

Description

This sample shows how to extend the predefined JTGO business classes and use the extended classes with the equipment component.

How to Use the Sample

The main frame contains the same equipment view as in the equipment/basic sample. Refer to the basic sample for details on interaction.

How to Run the Sample as an Application

This sample can also be run as an application. The installation directory contains an executable JAR file, equipment-custom-classes.jar, that allows you to execute the sample with a double click from a file browser. Note that if you are using Internet Explorer, you can open the installation directory and execute the JAR file from the browser. This technique may not work in other Web browsers.

Alternatively, you can run the sample application from the command line. First check that the Ant utility is properly configured. If not, see the instructions on how to configure Ant for Rogue Wave JViews.

Then, go to the installation directory of the sample and type:

ant run

Topics Covered

• Basic initialization
  See the equipment/basic sample for details
  
• Extending the predefined business classes
• Mapping extended attributes to graphic properties using cascading style sheets

Detailed Description

This sample differs from the basic sample in that it declares (in CustomLedClass) a custom subclass, CustomLed, of the predefined JTGO business class ilog.tgo.model.IltLed. CustomLed extends its parent by adding a status attribute. This attribute is:

• mapped to the foreground color of the LED by a value map associated with the property foreground,
• used as the tooltip text of the LED with the property toolTipText.
