问题:
Could someone please explain to me how to properly use the Anchors when creating cell comments? Mine were working, but the spread sheet changed and I am having issues getting my cell comments to appear. This is the code I was using that worked:
Comment c = drawing.createCellComment (new HSSFClientAnchor(0, 0, 0, 0, (short)4, 2, (short)6, 5));
That was found mostly by experimenting around. Looking at the api for it doesn't exactly make it any clearer.
Based on the quick start guide I have also tried the following with no luck:
ClientAnchor anchor = chf.createClientAnchor(); Comment c = drawing.createCellComment(anchor); c.setString(chf.createRichTextString(message));

A bit late, but this will probably work (it works for me, while the Apache POI example from the quick start also didn't work for me):
public void setComment(String text, Cell cell) { final Map drawingPatriarches = new HashMap(); CreationHelper createHelper = cell.getSheet().getWorkbook().getCreationHelper(); HSSFSheet sheet = (HSSFSheet) cell.getSheet(); HSSFPatriarch drawingPatriarch = drawingPatriarches.get(sheet); if (drawingPatriarch == null) { drawingPatriarch = sheet.createDrawingPatriarch(); drawingPatriarches.put(sheet, drawingPatriarch); } Comment comment = drawingPatriarch.createComment(new HSSFClientAnchor(0, 0, 0, 0, (short) 4, 2, (short) 6, 5)); comment.setString(createHelper.createRichTextString(text)); cell.setCellComment(comment); }

The following code works for me for Office 2007 (xlsx) format files. Figured this out from POI guide http://poi.apache.org/spreadsheet/quick-guide.html#CellComments and How to set comments for 3 cells using apache poi
protected void setCellComment(Cell cell, String message) { Drawing drawing = cell.getSheet().createDrawingPatriarch(); CreationHelper factory = cell.getSheet().getWorkbook() .getCreationHelper(); // When the comment box is visible, have it show in a 1x3 space ClientAnchor anchor = factory.createClientAnchor(); anchor.setCol1(cell.getColumnIndex()); anchor.setCol2(cell.getColumnIndex() + 1); anchor.setRow1(cell.getRowIndex()); anchor.setRow2(cell.getRowIndex() + 1); anchor.setDx1(100); anchor.setDx2(100); anchor.setDy1(100); anchor.setDy2(100); // Create the comment and set the text+author Comment comment = drawing.createCellComment(anchor); RichTextString str = factory.createRichTextString(message); comment.setString(str); comment.setAuthor("Apache POI"); // Assign the comment to the cell cell.setCellComment(comment); }
