This extension point allows for the contribution of various UI extensions which can be referenced from the <code>org.eclipse.cdt.managedbuilder.core.buildDefinitions</code> 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 <code>&lt;option&gt;</code> element of an <code>org.eclipse.cdt.managedbuilder.core.buildDefinitions</code> extension. 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 <code>&lt;option&gt;</code> element of an <code>org.eclipse.cdt.managedbuilder.core.buildDefinitions</code> extension. A unique identifier which will be used to reference this field-editor from an <code>&lt;option&gt;</code> element of an <code>org.eclipse.cdt.managedbuilder.core.buildDefinitions</code> extension. Specifies the Java class which implements the custom field-editor. This class must extend JFace's <code>FieldEditor</code> abstract class, and implement the <code>ICustomBuildOptionEditor</code> interface. 8.0 <extension point="org.eclipse.cdt.managedbuilder.ui.buildDefinitionsUI"> <fieldEditor id="org.eclipse.cdt.managedbuilder.ui.tests.fieldEditors.CustomFieldEditor" class="org.eclipse.cdt.managedbuilder.ui.tests.fieldEditors.CustomFieldEditor"/> </extension> None None Copyright (c) 2011 Texas Instruments Incorporated and others.
