# Intro Part

###### Identifier:

org.eclipse.ui.intro

###### Since:

3.0

###### Description:

This extension point is used to register implementations of special workbench parts, called intro parts, that are responsible for introducing a product to new users. An intro part is typically shown the first time a product is started up. Rules for associating an intro part implementation with particular products are also contributed via this extension point.

The life cycle is as follows:

- The intro area is created on workbench start up. As with editor and view areas, this area is managed by an intro site (implementing `org.eclipse.ui.intro.IIntroSite`).
- The id of the current product (Platform.getProduct()) is used to choose the relevant intro part implementation.
- The intro part class (implementing `org.eclipse.ui.intro.IIntroPart`) is created and initialized with the intro site.
- While the intro part is showing to the user, it can transition back and forth between full and standby mode (either programmatically or explicitly by the user).
- Eventually the intro part is closed (either programmatically or explicitly by the user). The current perspective takes over the entire workbench window area.

###### Configuration Markup:

<!ELEMENT extension (intro* , introProductBinding*)>

<!ATTLIST extension

point CDATA #REQUIRED

id CDATA #IMPLIED

name CDATA #IMPLIED>

- point - a fully qualified identifier of the target extension point
- id - an optional identifier of the extension instance
- name - an optional name of the extension instance

<!ELEMENT intro EMPTY>

<!ATTLIST intro

id CDATA #REQUIRED

icon CDATA #IMPLIED

class CDATA #REQUIRED

contentDetector CDATA #IMPLIED

label CDATA #IMPLIED>

Specifies an introduction. An introduction is a product-specific presentation shown to first-time users on product start up.

- id - a unique identifier for this introduction
- icon - a plug-in-relative file name of the icon that will be associated with this introduction
- class - a fully qualified name of the class implementing the `org.eclipse.ui.intro.IIntroPart` interface. A common practice is to subclass `org.eclipse.ui.part.intro.IntroPart` in order to inherit the default functionality. This class implements the introduction.
- contentDetector - a fully qualified name of a class extending `org.eclipse.ui.intro.IntroContentDetector`. This optional class is used to detect newly added introduction content. If new content is available, the view showing the introduction will be opened again.
- label - an string label for this introduction that will be used in the construction of the open action as well as the part label Since 3.2

<!ELEMENT introProductBinding EMPTY>

<!ATTLIST introProductBinding

productId IDREF #REQUIRED

introId IDREF #REQUIRED>

Specifies a binding between a product and an introduction. These bindings determine which introduction is appropriate for the current product (as defined by `org.eclipse.core.runtime.Platform.getProduct()`).

- productId - unique id of a product
- introId - unique id of an introduction

###### Examples:

The following is an example of an intro part extension that contributes an particular introduction and associates it with a particular product:

      <extension point="org.eclipse.ui.intro">
         <intro
            id="com.example.xyz.intro.custom"
            class="com.example.xyz.intro.IntroPart"/>
         <introProductBinding
            productId="com.example.xyz.Product"
            introId="com.example.xyz.intro.custom"/>
      </extension>

###### API Information:

The value of the `class` attribute must be the fully qualified name of a class that implements the`org.eclipse.ui.intro.IIntroPart` interface by subclassing `org.eclipse.ui.part.intro.IntroPart`.

###### Supplied Implementation:

There are no default implementations of the initial user experience. Each Eclipse-based product is responsible for providing one that is closely matched to its branding and function.
