如何在打印机上打印 JFace TreeViewer

发布于 2024-11-10 12:13:31 字数 490 浏览 4 评论 0原文

我正在 Eclipse 中开发一个插件，它在滚动复合中显示结果。该组合包含一个 JFace TreeViewer。我想将这个 TreeViewer 打印到打印机上。我发现 import org.eclipse.swt.printing.Printer;打印到打印机。

但是当我使用以下代码片段打印时，

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

我想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。它不显示类、方法的名称。

在我的声誉高于 10 之前，我无法发布屏幕截图。请在此处查看

如果我不清楚，请告诉我。

提前感谢

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.

But when i am printing using following snippet

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.

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

Please let me know if i am not clear..

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);
