| === How can I change the contents of a menu according to the selected file in the editor? |
| |
| * Create your action and let it implement link:http://bits.netbeans.org/dev/javadoc/org-openide-util/org/openide/util/actions/Presenter.Menu.html[Presenter.Menu] |
| * Return a special `JMenuItem` subclass that implements link:http://bits.netbeans.org/dev/javadoc/org-openide-awt/org/openide/awt/DynamicMenuContent.html[DynamicMenuContent] from `getMenuPresenter()` |
| * Implement link:http://bits.netbeans.org/dev/javadoc/org-openide-awt/org/openide/awt/DynamicMenuContent.html[DynamicMenuContent] methods to return the desired menu content, using link:http://bits.netbeans.org/dev/javadoc/org-openide-windows/org/openide/windows/TopComponent.Registry.html[TopComponent.Registry] for finding the selected file in the editor. |
| |
| link:https://bitbucket.org/jglick/dynamicmenudemo/[https://bitbucket.org/jglick/dynamicmenudemo/] also does something similar. |
| |
| === Can I hide or show a whole menu or toolbar? |
| |
| To hide a menu or toolbar you have to edit your `layer.xml` and append `_hidden` to the name of the desired menu or toolbar. You may also hide `*.instance` files. |
| |
| <syntaxhighlight lang="xml" enclose="div" highlight="6"> |
| <folder name="Menu"> |
| |
| [source,xml] |
| ---- |
| |
| <!-- Hide View menu --> |
| <folder name="View_hidden"/> |
| <folder name="SomeMenu"> |
| <!-- Hide a single menu item --> |
| <file name="SomeAction.instance_hidden"/> |
| </folder> |
| ---- |
| |
| </folder> |
| <folder name="Toolbars"> |
| |
| [source,xml] |
| ---- |
| |
| <!-- Hide Edit toolbar --> |
| <folder name="Edit_hidden"/> |
| ---- |
| |
| </folder> |
| </syntaxhighlight > |
| |
| It's generally much easier to do this from the NetBeans IDE, link:http://forums.netbeans.org/post-77476.html[as described here]. |
| |
| Note that to hide the Navigate menu one has to declare GoTo_hidden instead of Navigate_hidden (the menu was originally named GoTo, but was later renamed to Navigate by the means of Bundle.properties). |
