# Build Definitions UI Extensions

###### Identifier:

org.eclipse.cdt.managedbuilder.ui.buildDefinitionsUI

###### Since:

8.0

###### Description:

This extension point allows for the contribution of various UI extensions which can be referenced from the `org.eclipse.cdt.managedbuilder.core.buildDefinitions` extensions. Via this extension point, for example, the developer may contribute a custom JFace field-editor, which can then be referenced by its ID from an `<option>` element of an `org.eclipse.cdt.managedbuilder.core.buildDefinitions` extension.

###### Configuration Markup:

<!ELEMENT extension (fieldEditor*)>

<!ATTLIST extension

point CDATA #REQUIRED

id CDATA #IMPLIED

name CDATA #IMPLIED>

<!ELEMENT fieldEditor EMPTY>

<!ATTLIST fieldEditor

id CDATA #REQUIRED

class CDATA #REQUIRED>

This element can be used to contribute a custom JFace field-editor to represent a build-option in the project Properties dialog UI. Contributing a custom field-editor through this element is not enough - the custom field-editor must also be referenced by its ID from an `<option>` element of an `org.eclipse.cdt.managedbuilder.core.buildDefinitions` extension.

- id - A unique identifier which will be used to reference this field-editor from an `<option>` element of an `org.eclipse.cdt.managedbuilder.core.buildDefinitions` extension.
- class - Specifies the Java class which implements the custom field-editor. This class must extend JFace's `FieldEditor` abstract class, and implement the `ICustomBuildOptionEditor2` interface.
