| <usecase id="newProvider" name="How To Add New Quick Search Provider" > |
| In order to plug in a new Quick Search provider and new category of results, |
| module writers need to complete following steps: |
| |
| <h5>1. Implement <a href="@TOP@/org/netbeans/spi/quicksearch/SearchProvider.html">SearchProvider</a></h5> |
| <ul> |
| <li>Implement body of <b><code>SearchProvider.evaluate</code></b> method |
| like suggested in its <a href="@TOP@/org/netbeans/spi/quicksearch/SearchProvider.html">javadoc</a>. |
| </li> |
| </ul> |
| |
| <h5>2. Register SearchProvider implementation in xml layer</h5> |
| Register your SearchProvider implementation in your module's xml layer file under |
| main <b>"/QuickSearch"</b> folder. Registration xml syntax is following: |
| |
| <pre> |
| <folder name="QuickSearch"> |
| <folder name="Category1_ID"> |
| <attr name="position" intvalue="300"/> |
| <file name="org-netbeans-module1-package1-Provider1Impl.instance"/> |
| </folder> |
| <folder name="Category2_ID"> |
| <!--Attribute for localization - provide localized display name of category!--> |
| <attr name="SystemFileSystem.localizingBundle" stringvalue="org.netbeans.modules.yourmodule.YourBundle"/> |
| <!--Attribute for command prefix - used to narrow search to this category only!--> |
| <attr name="command" stringvalue="p"/> |
| <!--Attribute for category ordering!--> |
| <attr name="position" intvalue="200"/> |
| <!--Note that multiple providers can contribute to one category!--> |
| <file name="org-netbeans-module2-package2-Provider2Impl.instance"/> |
| <file name="org-netbeans-module2-package3-Provider3Impl.instance"/> |
| </folder> |
| </folder> |
| </pre> |
| |
| <b>Syntax explanation:</b> |
| <ul> |
| <li>Subfolders of "QuickSearch" define search result categories and their order.</li> |
| <li>Providers can share category by putting themselves under same subfolder.</li> |
| <li>Ordering of categories is done through NetBeans standard FileSystem API ordering |
| "position" attribute</li> |
| <li>Display name of category folder uses NetBeans standard FileSystem API |
| "SystemFileSystem.localizingBundle" attribute.</li> |
| <li>"command" attribute defines command prefix for category, which is used |
| to narrow Quick Search to only one category. Provide short prefix, ideally |
| containing one or two prefix, that will serve as command to narrow search |
| only this category. In above syntax example, if |
| user types 'p' and space key and then text, only "Category2_ID" category |
| will be searched.</li> |
| <li>If several providers share one category, then only one provider needs to |
| specify above attributes. Note however that if your provider shares |
| category with provider from different module, you should have dependency |
| on module which actually define those attributes. Dependency assures |
| there will always be category "description" for category that you are |
| sharing.</li> |
| </ul> |
| |
| </usecase> |
| |
| <usecase id="shareCategory" name="How To Share Category Of Results" > |
| <p>Quick Search UI shows search results divided into visually separeted sections, |
| called categories. Several <code>SearchProvider</code> implementations may decide to display |
| their results in one shared category of results in Quick Search UI.</p> |
| |
| <p>In order to share category, module writers have to agree on shared |
| category and its properties, especially its name. |
| It means that all providers (possibly in different NetBeans modules) |
| need to be registered under the same folder, as shown below:</p> |
| |
| <h5>Provider 1</h5> |
| Provider 1 is category "owner", which defines properties of <code>SharedCategory</code> such as |
| display name, position and command prefix. |
| <pre> |
| <folder name="QuickSearch"> |
| <folder name="SharedCategory"> |
| <attr name="SystemFileSystem.localizingBundle" stringvalue="org.netbeans.modules.yourmodule.YourBundle"/> |
| <attr name="command" stringvalue="p"/> |
| <attr name="position" intvalue="200"/> |
| <file name="org-netbeans-module1-package1-Provider1Impl.instance"> |
| <attr name="position" intvalue="300"/> |
| </file> |
| </folder> |
| </folder> |
| </pre> |
| |
| <h5>Provider 2</h5> |
| Other providers from other modules are sharing category with Provider 1. |
| Provider 2 does not define properties of <code>SharedCategory</code>, |
| as they were already defined by Provider 1. |
| Note that module dependency on the module of Provider 1 is needed |
| to ensure that <code>SharedCategory</code> is fully defined. |
| <pre> |
| <folder name="QuickSearch"> |
| <folder name="SharedCategory"> |
| <file name="org-netbeans-module2-package2-Provider2Impl.instance"/> |
| <attr name="position" intvalue="200"/> |
| </file> |
| </folder> |
| </folder> |
| </pre> |
| |
| <h5>Provider 3</h5> |
| The same rules apply like for Provider 2. Note that position attribute |
| can be used to control position of provider's results in shared category. |
| Results from provider with lowest position will go first and so on. |
| <pre> |
| <folder name="QuickSearch"> |
| <folder name="SharedCategory"> |
| <file name="org-netbeans-module2-package3-Provider3Impl.instance"/> |
| <attr name="position" intvalue="100"/> |
| </file> |
| </folder> |
| </folder> |
| </pre> |
| </usecase> |
| |
| <usecase id="categoryOrder" name="How To Define and Modify Order of Categories" > |
| Order of categories of results can be set by using "position" attribute |
| of category xml folder definition. Following example will result in |
| <code>FirstCategory</code> to be first, and <code>SecongCategory</code> to be second :), |
| which means that <code>FirstCategory</code> and its results will be |
| displayed above <code>Secondcategory</code> in QuickSearch results window. |
| |
| <pre> |
| <folder name="QuickSearch"> |
| <folder name="SecondCategory"> |
| <attr name="position" intvalue="300"/> |
| ... |
| </folder> |
| <folder name="FirstCategory"> |
| <attr name="position" intvalue="200"/> |
| ... |
| </folder> |
| </folder> |
| </pre> |
| </usecase> |
| |
| <usecase id="hideProvider" name="How To Hide Recent Searches Results and Others" > |
| "Recent Searches" provider is contained directly in <code>spi.quicksearch</code> |
| module, so its functionality is automatically always available by default. |
| However, if your module wants to disable "Recent Searches" or any other |
| category, follow the steps below: |
| |
| <h5>Define module dependency</h5> |
| Your module have to depend on module where provider you want to disable |
| is contained. In case of "Recent Searches" provider, it's <code>spi,quicksearch</code>, |
| on which you probably already depend. |
| |
| <h5>Disable provider using "_hidden"</h5> |
| For example, to disable "Recent Searches" provider, write into your layer: |
| |
| <pre> |
| <folder name="QuickSearch"> |
| <folder name="Recent_hidden"> |
| </folder> |
| </folder> |
| </pre> |
| |
| "Recent" is a name of category for "Recent Searches" provider and by appending |
| "_hidden" suffix you are telling system to "hide" it. This technique |
| can be used also to disable invidual search providers. |
| </usecase> |
| |
| <usecase id="usageInPlatform" name="How To Use Quick Search in Platform Application" > |
| Quick Search UI is disabled by default in application built on top of |
| NetBeans platform. To enable Quick Search feature in your application, |
| complete following steps: |
| |
| <h5>1. Write XML layer registration</h5> |
| Add the following lines to XML layer of some of your modules in your |
| application suite: |
| |
| <pre> |
| <folder name="Toolbars"> |
| <folder name="QuickSearch"> |
| <attr name="SystemFileSystem.localizingBundle" stringvalue="com.myapp.mymodule.MyBundle"/> |
| <file name="org-netbeans-modules-quicksearch-QuickSearchAction.shadow"> |
| <attr name="originalFile" stringvalue="Actions/Edit/org-netbeans-modules-quicksearch-QuickSearchAction.instance"/> |
| </file> |
| </folder> |
| </folder> |
| </pre> |
| |
| <h5>2. Localize Toolbar Name</h5> |
| Replace <code>com.myapp.mymodule.MyBundle</code> in the xml registration |
| above with path to your properties file, in which you'll define |
| localized name of Quick Search toolbar: |
| <pre> |
| Toolbars/QuickSearch=Quick Search |
| </pre> |
| |
| <p>By default, providers for searching in actions and recent searches |
| will be enabled. Web search provider is disabled by default, see use case |
| below for info how to turn it on.</p> |
| </usecase> |
| |
| <usecase id="searchWebProvider" name="How To Add a Default Web Search Provider" > |
| There is a default implementation of web search provider which uses Google |
| to search for the given text on the web. Simply add the following lines to your XML layer |
| to enable this search provider in your application: |
| <pre> |
| <folder name="QuickSearch"> |
| <folder name="WebSearch"> |
| <!--Attribute for localization - provide localized display name of category!--> |
| <attr name="SystemFileSystem.localizingBundle" stringvalue="com.myapp.mymodule.MyBundle"/> |
| <!--Attribute for command prefix - used to narrow search to this category only!--> |
| <attr name="command" stringvalue="g"/> |
| <!--Attribute for category ordering!--> |
| <attr name="position" intvalue="200"/> |
| <!--Note that multiple providers can contribute to one category!--> |
| <file name="org-netbeans-modules-quicksearch-web-WebQuickSearchProviderImpl.instance"/> |
| </folder> |
| </folder> |
| </pre> |
| You can also add branding for <code>org.netbeans.modules.quicksearch.web</code> Bundle to restrict |
| the search to a particular site only: |
| <pre> |
| quicksearch.web.site=mywebsite.com |
| </pre> |
| And you can also restrict the search to some parts your website only: |
| <pre> |
| quicksearch.web.url_patterns=mywebsite.com/docs,mywebsite.com/files/tutorials |
| </pre> |
| </usecase> |
| |
| <usecase id="customizeLookAndFeel" name="How to customize Look&Feel properties"> |
| If you need to adjust border of the Quick Search component for your |
| Look&Feel, you can put a <code>Border</code> instance into |
| <code>UIManager</code> under key <code>nb.quicksearch.border</code>. |
| </usecase> |
