Hi, I put the small app on the GitHub at that link : https://github.com/bgry/netbeans_rcp_tests/tree/master/Workspace_test_netbeans.

I created my custom TopComponents with some annotations as follow : @ConvertAsProperties( dtd = "-//project.editor.hmi//EditorShape//EN", autostore = false ) @TopComponent.Description( preferredID = "EditorShapeTopComponent", iconBase = "project/editor/shape_24.png", persistenceType = TopComponent.PERSISTENCE_ALWAYS ) //@TopComponent.Registration(mode<mailto://@TopComponent.Registration(mode> = "leftSlidingSide", openAtStartup = true) @ActionID(category = "Window", id = "project.editor.hmi.EditorShapeTopComponent") //@ActionReference(path = "Menu/Window" /*, position = 333 */) @TopComponent.OpenActionRegistration( displayName = "#CTL_EditorShapeAction", preferredID = "EditorShapeTopComponent" ) @Messages({ "CTL_EditorShapeAction=Formes", "CTL_EditorShapeTopComponent=Formes", "HINT_EditorShapeTopComponent=Formes simples importables" }) public final class EditorShapeTopComponent extends TopComponent { ... } I have a configuration file (properties file) in which a parameter tells if the TopComponent must be activated or not. To manage the visibility of the TopComponent, I do that : public GlobalActionContextProxy() { ... WindowManager.getDefault().invokeWhenUIReady(new Runnable() { @Override public void run() { // Hack to force the current Project selection when the application starts up TopComponent tc = WindowManager.getDefault().findTopComponent(PROJECT_LOGICAL_TAB_ID); if (tc != null) { tc.requestActive(); } SwingUtilities.invokeLater(new Runnable() { @Override public void run() { // Reads the configuration file. Configuration configuration = CentralLookup.getDefault().lookup(Configuration.class); // Here we check that the parameter is the configuration file is to true. if (configuration.getBoolean("withImages", false) == true) { // Adds to Menu. FileObject menuFolder = FileUtil.getConfigFile("Menu/Window"); try { registerAction(SycloneEditorImagePaletteTopComponent.class, Bundle.LBL_SycloneEditorImagePaletteTopComponent(), new ImageIcon(getClass().getResource("/fr/clemessy/ast/syclone/project/synoptic/editor/img_24.png")), menuFolder, 333); } catch (IOException ex) { Exceptions.printStackTrace(ex); } // Adds to left dock. if (!isTopComponentInUserDirCache(SycloneEditorImagePaletteTopComponent.class)) { SycloneEditorImagePaletteTopComponent tcPalette = new SycloneEditorImagePaletteTopComponent(); Mode leftSideMode = WindowManager.getDefault().findMode("leftSlidingSide"); leftSideMode.dockInto(tcPalette); tcPalette.open(); } } else { // Removes the file from the cache : avoid it to be reopened by the persistence manager. removeTopComponentInUserDirCache(SycloneEditorImagePaletteTopComponent.class); } } }); } }); } The method isTopComponentInUserDirCache is as follow : /** * Checks if a component appears in the userdir cache of Netbeans. * * @param <T> : child class of TopComponent. * @param classType : class type. * @return true if the component is in the cache, false otherwise. */ private <T extends TopComponent> boolean isTopComponentInUserDirCache(final Class<T> classType) { boolean isInCache = false; // Gets the directory which contains cache on Components. Path compDirPath = getUserDirComponentsSettingPath(); // It the directory exists, checks if the component has already been opened. File compDirFile = compDirPath.toFile(); if (compDirFile.exists()) { // Gets the files referencing the component. File[] compFiles = compDirFile.listFiles(new FilenameFilter() { @Override public boolean accept(File dir, String name) { StringBuilder filenameMatcher = new StringBuilder("^"); filenameMatcher.append(classType.getSimpleName()); filenameMatcher.append("(_\\d*)?"); filenameMatcher.append(".settings$"); return name != null && name.matches(filenameMatcher.toString()); } }); // If there is at least 1 file, the component has already been opened. if (compFiles != null && compFiles.length > 0) { isInCache = true; } } return isInCache; } With this solution, it seems to work but it is not very clean. And when I change the language, the menu item (linked to the TopComponent), which is read from the cache, is not translated. How could I do it in a cleanest way ? The only reason I don’t use annotations on the TopComponent is because I need to tell “open the TopComponent only if it is defined in the configuration file” : is there a way to do it properly ?
