Rogue Wave JViews TGO Sample: Table Component - Basic

Description

This sample shows how to use the basic features of the Rogue Wave JViews TGO table component.

How to Use the Sample

The sample shows a table that contains various types of predefined JTGO business objects. The table allows you to select rows, as well as to move and resize columns. You can choose the class of objects to display with a combo box in the lower part of the screen.

• To select a row, click anywhere inside one of its cells. Use the Shift key to select several adjacent rows or Ctrl to select individual rows.
• To move a column, click its header and drag it to a new location. To resize it, click the separator between two columns in the header and drag it left or right.
• The table also allows you to sort the rows based on the contents of one or more columns. To do so, click a column header; an indicator of the sort order will appear. Clicking again inverts the order, clicking a third time removes the indicator.
• The data can also be sorted based on more than one column. To add a column to refine the sort, use the Shift key and click the column header. Note that an indicator of the priority appears in the column header, and that the first column selected has the highest priority. You can sort on as many columns as you want. If multiple columns are sorted, you should shift-click the header to change the sort order for a column.
• To replace the current sort order with a new one, click any column header.

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, table-basic.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

• Initializing a JTGO application.
• Creating a table component.
• Setting the business class accepted by the component.
• Setting the project configuration.
• Adding the table to your Swing application.

Detailed Description

This sample shows how to create and use a JTGO table component and use its basic features. The specific code of this sample is in the doSample method of basic.Main. It contains the following steps:

• Initialize the application using the method ilog.cpl.IlpSystem.Init.
  You can pass the name of a deployment descriptor file to this method, but in this sample you do not need one.
• Create a table component.
  The table component is of the class ilog.cpl.IlpTable, a JavaBean with a default constructor.
• Specify which business class will be displayed by the table component using the the ilog.cpl.IlpTable.setAcceptedClass method.
  In this case, we initially show instances of IltNetworkElement. However, the sample provides a combo box to change the class of objects displayed.
• Create a combo box to change the class displayed.
  The combo box and its listener are standard Swing components. When triggered, the listener will call the ilog.cpl.IlpTable.setAcceptedClass method of the table component to show instances of a different class.
• Load a project configuration (project) from an XML file.
  The project configuration defines the component configuration files (CSS files) and the data source information. When the project file is set, the following steps are performed:
• • The configuration files are applied to the component.
  • A data source is created according to the class specified in the project configuration. In this case, it creates a standard data source of class IltDefaultDataSource.
  • The data file network is read containing predefined JTGO classes (business objects).
  • And finally the data source is attached to the component.
  The component configuration can also be specified later through the method ilog.cpl.IlpTable.setStyleSheets, you pass the name of a configuration file (table) which describes the:
  • View configuration
  • Interactor configuration
  • Table header configuration
  • Table cell configuration
  The data source and its contents can also be specified in the table component through the method ilog.cpl.IlpTable.setDataSource and ilog.cpl.datasource.IlpDefaultDataSource.parse.
• Add the table to your Swing application.
  IlpTable is a Swing JComponent, so it can be added to your application like any other Swing component.
