以编程方式创建GMF图 [英] Create GMF diagram programmatically

问题描述

我尝试使用EMF& amp;创建一个简单的图表Eclipse插件中的GMF。我创建了一个带有两个节点和放大器的Ecore。连接。我可以从中生成GMF。当我运行我的应用程序时，我得到了味觉，并且在我的帮助下，我能够绘制GMF图。但我想以编程方式。

I trying to create one simple diagram using EMF & GMF in Eclipse plug-ins. I have created one Ecore with two node & connection. I am able to generate GMF out of that. When I run my application I am getting the palate and with the help of that I am able to draw the GMF diagram. But I want that programmatically.

我已经从Ecore中创建了一个XML，并成功地将该XML加载到EMF对象中。所以我的EObject具有XML值。现在我想要自动生成GMF图。与打开一个示例RCP视图一样，它应该加载GMF内容。

I have created one XML out of that Ecore and successfully able to load that XML into the EMF object. So my EObject is having that XML values. Now I want a GMF diagram out of that automatically. like with the opening of one sample RCP view it should load the GMF content.

问题是我是这个GMF和EMF的新手，所以我不知道哪个类我要修改或者我要编写什么。

The problem is that I am new to this GMF and EMF, so I don't know which class I have to modify or what I have to write.

推荐答案

我有一个解决方案：

    ResourceSet resourceSet = new ResourceSetImpl();
    Diagram diagram = NotationFactory.eINSTANCE.createDiagram();
    diagram.setMeasurementUnit(MeasurementUnit.PIXEL_LITERAL);
    diagram.getStyles().add(NotationFactory.eINSTANCE.createDiagramStyle());
    diagram.setElement(object); //your EObject that should be referenced to this diagram (probably an ecore file)
    diagram.setType("Ecore");
    URI diagUri = URI.createFileURI(yourPathToECoreFile + "_diagram");
    Resource diagramResource = resourceSet.createResource(diagUri);
    diagramResource.getContents().add(diagram);

经过多个小时的研究后它对我有用

It works for me... after many hours of research

PS：该图应与您的ecore文件位于同一位置

PS: The diagram should be at the same place as your ecore file
