如何在Eclipse Kepler中撰写图像？

Question

This is a followup to Items decorations in a TreeViewer : I have a TreeView with my own Objects. I already have a LabelProvider that supplies Icons and Texts. Now I want to decorate the images with other images depending on some conditions. How can I do this? The referenced question uses ComposedImage , which I suppose is org.eclipse.emf.edit.provider .

Is there a way to do this with SWT/JFace in Eclipse 4.3?

I already tried using a ILightweightLabelDecorator (using the idea from the FAQ ), but gave up wrapping that round my LabelProvider .

Answer 1

ILightweightLabelDecorator is really the best way to do this. Wrap your label provider with a DecoratingLabelProvider as described in this answer: Using a ILightweightLabelDecorator decorator Use the org.eclipse.ui.decorators extension point to declare your lightweight decorator.

Answer 2

您可能需要查看org.eclipse.jface.viewers.DecorationOverlayIcon ，它基本上由装饰提供程序使用。
