Chapter 11, Creating Extension Points: How Others Can Extend Your Plug-ins

This extension-point provides a common pulldown item on the application toolbar where all of our tool commands may execute. This requires a simple framework that can be easily implemented using an extension point.

As others build additional tool plug-ins, they can use this extension point mechanism to add tool command menu items.

Configuration Markup:

<!ELEMENT tool EMPTY>

<!ATTLIST tool

action CDATA #REQUIRED

label  CDATA #REQUIRED>

Tool action to be added to pulldown menu.

• action - a fully qualified name of a class which implements com.ibm.jdg2e.extensionpoint.IToolAction
• label - a translatable name used either as the the command label. The name can include mnenomic information

<!ELEMENT extension (tool)>

point CDATA #REQUIRED
