如何将JFace TreeViewer打印到打印机上

I am developing a plugin in Eclipse, that shows the results in a scrolledComposite. The composite contains a JFace TreeViewer. I want to print this TreeViewer to the printer. I found import org.eclipse.swt.printing.Printer; to print to the printer.

我正在Eclipse中开发一个插件,它在scrolledComposite中显示结果。该组合包含一个JFace TreeViewer。我想将这个TreeViewer打印到打印机。我找到了import org.eclipse.swt.printing.Printer;打印到打印机。

But when i am printing using following snippet

但是,当我使用以下代码段进行打印时

GC gc= new GC(printer);
Control abc[] = Composite.getChildren();
abc[0].print(gc);

The tree that i want to print contains the workspace, project explorer. The print output is showing only the icons. it is not displaying the names of classes, methods.

我要打印的树包含工作区,项目资源管理器。打印输出仅显示图标。它没有显示类,方法的名称。

i cant post screenshot till my reputation is above 10.check it here

Thanks in advance

        Tree myWidget = treeViewer.getTree();
    Point size = myWidget.getSize();
    Image image = new Image(display, size.x, size.y);
    GC gc = new GC(myWidget);
    gc.copyArea(image, 0, 0);
    gc.dispose();

    // Get the ImageData and create a new printer Image from it
    ImageData imageData = image.getImageData();
    Image printImage = new Image(printer, imageData);
