| === How can I get the position of the caret in the currently selected editor window? |
| |
| You need to first get the selected node (which if the Editor is selected, should correspond to the file being edited); get the most recent editor pane open on it; and then access the caret: |
| |
| [source,java] |
| ---- |
| |
| Node[] n = TopComponent.getRegistry().getActivatedNodes(); |
| if (n.length == 1) { |
| EditorCookie ec = (EditorCookie) n[0].getCookie(EditorCookie.class); |
| if (ec != null) { |
| JEditorPane[] panes = ec.getOpenedPanes(); |
| if (panes.length > 0) { |
| int cursor = panes[0].getCaret().getDot(); |
| String selection = panes[0].getSelectedText(); |
| // USE selection |
| } |
| } |
| } |
| ---- |
| |
| Or |
| |
| [source,java] |
| ---- |
| |
| org.netbeans.api.editor.EditorRegistry.lastFocusedComponent().getCaretPosition() |
| ---- |
| |
| === How can I get the linenumber/column of the currently selected editor? |
| |
| [source,java] |
| ---- |
| |
| JTextComponent editor = org.netbeans.api.editor.EditorRegistry.lastFocusedComponent(); |
| |
| //using StyledDocument |
| { |
| StyledDocument sdocument = (StyledDocument) editor.getDocument(); |
| |
| int line = NbDocument.findLineNumber(sdocument, editor.getCaretPosition()); |
| int column = NbDocument.findLineColumn(sdocument, editor.getCaretPosition()); |
| } |
| //using BaseDocument |
| { |
| try { |
| BaseDocument bdocument = Utilities.getDocument(editor); |
| int line = Utilities.getLineOffset(bdocument, editor.getCaretPosition()); |
| } catch (BadLocationException ex) { |
| Exceptions.printStackTrace(ex); |
| } |
| } |
