如何去除webtop中browsetree 中的add repository链接
在用webtop做客户化的时候，如果只有一个repository 客户一般会要求去除左边导航树中的add repository 功能链接。操作步骤如下:
step1.Create your custom control class as follows . When the control initializes, it will display only the
nodes that are defined in the browsertree component, and it will set the visibility of the dynamic
nodes to false:
package com.mycompany;import java.util.Iterator;import com.documentum.web.common.ArgumentList;import com.documentum.web.form control.TreeNode;public class WebTopBrowserTree extends com.documentum.webtop.control.WebTopBrowserTree{public void onInit(ArgumentList args){super.onInit(args);Iterator it = getAllNodes();if (null ! = it){Object m _Node = null;while (it.hasNext()){m _Node = it.next();}if (null ! = m _Node){(//get last tree node set it visible false(TreeNode) m _Node).setVisible(false);}}}}step2.Create your custom comoponent Browsertree class as follows:
package com.mycompany;import com.documentum.web.common.ArgumentList;import com.broadtext.WebTopBrowserTree;public class BrowserTree extends com.documentum.webtop.webcomponent.browsertree.BrowserTree{public BrowserTree() {super();}public void onInit(ArgumentList args){//force creation of custom control in componentWebTopBrowserTree tree = (WebTopBrowserTree) getControl(TREE_CONTROL, WebTopBrowserTree.class);super.onInit(args);}}
step3.create a tag class to get the new control:
package com.mycompany;public class WebTopBrowserTreeTag extends com.documentum.webtop.control.WebTopBrowserTreeTag{protected Class getControlClass(){return com.mycompany.WebTopBrowserTree.class;}} step4 Now create a tag library file custom .tld in /WEB-INF/tlds . Copy the content of dmwebtop_1_0 .tld and change only the shortname element for the tag library and the tag class for the browsertree control, as shown:
. . .<shortname>ct< /shortname><tag><name>browsertree< /name><tagclass>com.mycompany.WebTopBrowserTreeTag< /tagclass>. . .< /tag> . . . step5 Extend the Webtop browsertree component definition in /webtop/config/browsertree_component.xml and use the following definition:
<config version ="1 .0"><scope><component id ="browsertree" extends ="browsertree:webtop/config/browsertree_component.xml"><pages><start>/custom/browsertree/browsertree.jsp< /start>< /pages><class>com.mycompany.BrowserTree< /class>< /component>< /scope>< /config>the last step, copy the Webtop browsertree JSP page /webtop/classic/browsertree .jsp to
/custom /browsertree.jsp Specify your custom tag library:
<%@ taglib uri ="/WEB -INF/tlds/custom.tld" prefix ="ct" %>
Import y our custom control class by importing it in place of the W ebtop control in the import
statement:
<%@ page import ="com.documentum.web.form.Form,com.documentum.web.common.ClientInfo,com.documentum.web.common.ClientInfoService,com.mycompany.BrowserTree" %>
Search for the browsertree tag:
<dmwt:browsertree name ='<% =BrowserTree.TREE _CONTROL%>' . . . />
Replace it with y our custom tag:
<ct:browsertree name ='<% =BrowserTree.TREE _CONTROL%>' . . . />
Stop and restart the app server to pick up your custom classes and verify that the Add Repository
option is not visible:
