| <text xml:space="preserve">===How can I get a list of open editor windows?=== |
| |
| ====To obtain a reference to the currently selected editor==== |
| |
| <pre> |
| Node[] arr = TopComponent.getRegistry().getCurrentNodes(); |
| for (int i = 0; i < arr.length; i++) { |
| EditorCookie ec = (EditorCookie) arr[i].getCookie(EditorCookie.class); |
| if (ec != null) { |
| JEditorPane[] panes = ec.getOpenedPanes(); |
| if (panes != null) { |
| // USE panes |
| } |
| } |
| } |
| </pre> |
| Note that EditorCookie.getOpenPanes() is deprecated (https://netbeans.org/bugzilla/show_bug.cgi?id=223383). Use <code>org.openide.text.NbDocument.findRecentEditorPane(EditorCookie)</code> instead. |
| |
| |
| ====To obtain references to all opened editors==== |
| <pre> |
| Set<TopComponent> comps = TopComponent.getRegistry().getOpened(); |
| for (TopComponent tc: comps) { |
| Node[] arr = tc.getActivatedNodes(); |
| for (int j = 0; j < arr.length; j++) { |
| EditorCookie ec = (EditorCookie) arr[j].getCookie(EditorCookie.class); |
| if (ec != null) { |
| JEditorPane[] panes = ec.getOpenedPanes(); |
| if (panes != null) { |
| // USE panes |
| } |
| } |
| } |
| } |
| </pre> |
| |
| ====Variants to get the Editor TopComponents==== |
| =====Variant A)===== |
| <pre> |
| private Collection<TopComponent> getCurrentOpenedEditors() { |
| final ArrayList<TopComponent> result = new ArrayList<TopComponent>(); |
| final WindowManager wm = WindowManager.getDefault(); |
| for (Mode mode : wm.getModes()) { |
| if (wm.isEditorMode(mode)) { |
| //result.addAll(Arrays.asList(mode.getTopComponents())); OR even faster |
| result.addAll(Arrays.asList(wm.getOpenedTopComponents(mode))); |
| } |
| } |
| return result; |
| } |
| |
| </pre> |
| |
| =====Variant B)===== |
| <pre> |
| private TopComponent getCurrentEditor() { |
| Set<? extends Mode> modes = WindowManager.getDefault().getModes(); |
| for (Mode mode : modes) { |
| if ("editor".equals(mode.getName())) { |
| return mode.getSelectedTopComponent(); |
| } |
| } |
| return null; |
| } |
| |
| //or |
| private TopComponent getCurrentEditor() { |
| Mode editor = WindowManager.getDefault().findMode("editor"); |
| return editor.getSelectedTopComponent(); |
| } |
| </pre> |
