Defining Extension Points

Define the following extension points in the manifest using the extension:

  • Ribbon
  • Events
  • Commands

Extension Point Details​

For details on extension points, see Extension Points.

Implementation Example​

This example shows a simple implementation of an extension point that defines one button to execute the functionality of the extension.

  • Define ribbon representing the ribbon configuration and commands representing the commands to be executed in the extensionPoints section.
  • Define controls such as tabs, groups, and buttons that make up the ribbon.
  • Assign commands to be executed to the buttons.

In this example, the extensionPoints.ribbon.tabs[0].groups[0].controls[0].command property is set to the command ID Command.SayHello, which will be defined later.

  • The command defines the ID, title, and command handler function name of the command to be executed.

In this example, the extensionPoints.commands property defines the command with ID Command.SayHello as the first execution command.
The name SayHello in the extensionPoints.commands[0].execFunc property is the function name of the command handler that will be implemented in the entry point's executable program.
