如何在资源上删除以前添加的装饰器? [英] How to remove a previously added decorator on a resource?
问题描述
这里有人知道如何删除资源上的特定装饰器?我将 org.eclipse.ui.decorators
扩展到我的项目,并创建了一个实现 ILightweightLabelDecorator
的类。在装饰器类中,我测试了条目是否是项目,并在调用 decorator.addOverlay()
之前进行其他测试。我没有实现其他功能,例如 removeListener
, isLabelProperty
, dispose
, addListener
,因为我目前看不到使用。
任何想法,资源,关于如何进行的评论将大有帮助。
Does anyone here knows how to remove a particular decorator on a resource? I extended org.eclipse.ui.decorators
to my project and created a class that implements ILightweightLabelDecorator
. In the decorator class I tested if the entry was a project and other test before calling decorator.addOverlay()
. I did not implemented the other functions such as removeListener
, isLabelProperty
, dispose
, addListener
since I currently do not see the use.
Any idea, resources, comment on how to proceed would greatly help.
代码:装饰功能
QualifiedName decorator = new QualifiedName("decorator", "value");
if (element instanceof IProject) {
IProject res = (IProject) element;
if (!res.isOpen()) {
return;
}
String val = null;
try {
val = res.getPersistentProperty(decorator);
} catch (CoreException e) {
e.printStackTrace();
}
if (val != null && val.equals(DecoratorState.ACTIVE)) {
decoration.addOverlay(ImageDescriptor.createFromFile(MyDecorator.class,
"/icons/sample.gif"), IDecoration.BOTTOM_RIGHT);
decoration.addSuffix(" [Using Enhancement]");
}
}
