Apache NetBeansHow can I get a list of open editor windows?
To obtain a reference to the currently selected editor
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
}
}
}Note that EditorCookie.getOpenPanes() is deprecated (https://bz.apache.org/netbeans/show_bug.cgi?id=223383). Use org.openide.text.NbDocument.findRecentEditorPane(EditorCookie) instead.
To obtain references to all opened editors
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
}
}
}
}Variants to get the Editor TopComponents
Variant A)
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;
}Variant B)
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();
