private void removeUnwantedPreferencesPages() { private void removePrefsPage(IPreferenceNode root, String id) { If you need to know the ID of the preference page you wish to remove, simply walk the tree and print all the nodes instead of removing selected ones. <\/p>\n Hope this helps someone. I recently wanted to get rid of a preference page I did not want to expose in Mission Control (an Eclipse RCP based application), and ended up with the following code in my ApplicationWorkbenchWindowAdvisor: private void removeUnwantedPreferencesPages() { PreferenceManager pm = PlatformUI.getWorkbench().getPreferenceManager(); IPreferenceNode root = getRoot(pm); removePrefsPage(root, "org.eclipse.equinox.security.ui.category"); \/\/$NON-NLS-1$} private IPreferenceNode getRoot(PreferenceManager pm) { try […]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-171","post","type-post","status-publish","format-standard","hentry","category-java-mission-control-fair-dj"],"_links":{"self":[{"href":"https:\/\/hirt.se\/blog\/index.php?rest_route=\/wp\/v2\/posts\/171","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hirt.se\/blog\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/hirt.se\/blog\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/hirt.se\/blog\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/hirt.se\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=171"}],"version-history":[{"count":5,"href":"https:\/\/hirt.se\/blog\/index.php?rest_route=\/wp\/v2\/posts\/171\/revisions"}],"predecessor-version":[{"id":192,"href":"https:\/\/hirt.se\/blog\/index.php?rest_route=\/wp\/v2\/posts\/171\/revisions\/192"}],"wp:attachment":[{"href":"https:\/\/hirt.se\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=171"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/hirt.se\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=171"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/hirt.se\/blog\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=171"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
