org.eclipse.ui.cheatsheets.AbstractItemExtensionElement

Base class for adding controls to cheat sheet items.

Subclasses are used in conjunction with the org.eclipse.ui.cheatsheets.cheatSheetItemExtension extension point. Subclasses must be public and have a public 1-arg constructor that takes the name of the attribute type String. The extension point specifies the name of the subclass and the name of the XML attribute that it can handle. When the cheat sheet framework encounters an item (or subitem) element in the cheat sheet content file with an attribute with a matching name, an instance of the corresponding item extension subclass is created. It is up to this instance to remember the attribute value if required. Later, when creating the visual controls for the item are being created, the instance is given the opportunity to add extra controls.
