Build Identifier: M20080911-1700 On Windows XP, a conventional print option is to output to an <>.mdi (Microsoft Document Image) file. On Windows, this has been replaced with format XPS (microsoft's XML Paper Specification). A modified "org.eclipse.draw2d.printing.PrintExample.java" will properly output to the MDI format on Windows XP, but not output to XPS on Windows7. The modification is simply to include a Print Dialog that allows the user to select desired printer. This problem is also verified with Eclipse 3.5.2 Reproducible: Always Steps to Reproduce: 1. Modify "org.eclipse.draw2d.printing.PrintExample.java" with new printIt() as provided below. 2. Run example on Windows XP: confirm printing to MDI file and format works. 3. run example on Widwos 7, confirm printing to XPS file and format does NOT work. static private void printIt(IFigure fig){ PrintDialog dialog = new PrintDialog(Display.getCurrent().getActiveShell(), SWT.NULL); PrinterData data = dialog.open(); if (data != null) { Printer p = new Printer(data); PrintOperation op = new PrintFigureOperation(p, fig); op.setPrintMargin(new Insets(0,0,0,0)); op.run("Test"); // "Test" is the print job name p.dispose(); } }
Note that GEF examples, at least Logic, do NOT exhibit this problem.
Note that it seems like ONLY the last figure in a depth first recursive walk of a Figure tree, is rendered onto XPS.
This is most likely an issue with SWT Win 7 printing. Here is an SWT snippet that reproduces the problem: import org.eclipse.swt.*; import org.eclipse.swt.widgets.*; import org.eclipse.swt.graphics.*; import org.eclipse.swt.printing.*; public class TestSnippet { public static void main (String [] args) { Display display = new Display(); Shell shell = new Shell(display); shell.open (); PrinterData data = Printer.getDefaultPrinterData(); if (data == null) { System.out.println("Warning: No default printer."); display.dispose(); return; } Printer printer = new Printer(data); if (printer.startJob("SWT Printing Snippet")) { Color black = printer.getSystemColor(SWT.COLOR_BLACK); Color white = printer.getSystemColor(SWT.COLOR_WHITE); Rectangle trim = printer.computeTrim(0, 0, 0, 0); Point dpi = printer.getDPI(); int leftMargin = dpi.x + trim.x; // one inch from left side of paper if (leftMargin < 0) leftMargin = -trim.x; // make sure to print on the printable area int topMargin = dpi.y / 2 + trim.y; // one-half inch from top edge of paper if (topMargin < 0) topMargin = -trim.y; // make sure to print on the printable area GC gc = new GC(printer); if (printer.startPage()) { gc.setBackground(white); gc.setForeground(black); float scale = Math.round((float) printer.getDPI().x / display.getDPI().x); int size = Math.round(scale * 50); int offset = Math.round(scale * 5); gc.setClipping(leftMargin, topMargin, size , size); gc.drawRectangle(leftMargin, topMargin, size, size); gc.setClipping(leftMargin + size + offset, topMargin, size, size); gc.drawRectangle(leftMargin + size + offset, topMargin, size, size); printer.endPage(); } gc.dispose(); printer.endJob(); } printer.dispose(); while (!shell.isDisposed ()) { if (!display.readAndDispatch ()) display.sleep (); } display.dispose(); } } Snippet needs to be verified on Win XP. If it works on XP, I'll raise a defect against SWT.
The snippet works on XP - SWT issue.
Resolving as INVALID due to comment #4.
