| <p>Plug-ins can also define marker resolutions, so that their problem markers can |
| participate in the workbench <b>Quick Fix</b> feature. Users can select |
| a problem marker and choose a <b>Quick Fix</b> from a popup containing the list of supplied |
| fixes contributed for the marker.</p> |

| |
| <p>Marker resolutions are contributed using the <b><a href="../reference/extension-points/org_eclipse_ui_ide_markerResolution.html">org.eclipse.ui.ide.markerResolution</a></b> |
| extension point. This extension point allows plug-ins to associate a <b>class</b> |
| that implements <b><a href="../reference/api/org/eclipse/ui/IMarkerResolutionGenerator.html">IMarkerResolutionGenerator</a></b> |
| with a particular type of marker. The marker can be qualified |
| by marker type only, or it can be further qualified by the value of one or more of its |
| attributes. The JDT contributes a marker resolution for Java problems:</p> |
| |
| <pre> |
| <extension |
| point="org.eclipse.ui.ide.markerResolution"> |
| <markerResolutionGenerator |
| markerType="org.eclipse.jdt.core.problem" |
| class="org.eclipse.jdt.internal.ui.text.correction.CorrectionMarkerResolutionGenerator"> |
| </markerResolutionGenerator> |
| </extension> |
| </pre> |
| |
| <p>The marker resolution generator is responsible for returning an array of |
| marker resolutions (<a href="../reference/api/org/eclipse/ui/IMarkerResolution.html"><b>IMarkerResolution</b></a>) |
| that will be shown in the <b>Quick Fix</b> popup. The resolution will |
| be <b>run()</b> if the user selects one of the fixes.</p> |
| <p><img src="images/markerresolution.png" alt="Marker resolutions" border="0"></p> |
| <p> |
| The Problems view supports resolving multiple problems at once. The user can |
| add other matching problems to the list of problems to fix, and then apply all |
| fixes in one go. To support multiple resolutions, your implementation of <a href="../reference/api/org/eclipse/ui/IMarkerResolution.html">IMarkerResolution</a> |
| must be a subclass of <a href="../reference/api/org/eclipse/ui/views/markers/WorkbenchMarkerResolution.html">WorkbenchMarkerResolution</a>. |
