Perforce JViews TGO Sample: Table Component - Custom Attributes

Description

This sample shows how to add custom attributes to a JViews TGO table component.

How to Use the Sample

This sample displays reference and computed attributes. As in the basic sample, you can change the column order and the way rows are sorted.

How to Run the Sample as an Application

This sample can be run as an application. The installation directory contains an executable JAR file, table-customAttributes.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 Perforce JViews.

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

ant run

Topics Covered

• Basic initialization and usage.

Detailed Description

This sample differs from the basic sample in that:

• The first two columns of the table are fixed.
