如何设置Eclipse/RCP装饰器的颜色? [英] How to set the color of an Eclipse/RCP decorator?

问题描述

我通过 plugin.xml 在Eclipse/RCP应用程序中的树查看器项中添加了一个装饰器:

I added a decorator in a Eclipse/RCP application to my tree viewer items by plugin.xml:

<extension point="org.eclipse.ui.decorators">
      <decorator
            adaptable="true"
            class="sernet.verinice.samt.rcp.TopicDecorator"
            id="sernet.verinice.samt.rcp.TopicDecorator"
            label="ISA Topic decorator"
            lightweight="true"
            location="BOTTOM_LEFT"
            state="true">
         <enablement>
            <objectClass name="sernet.verinice.model.samt.SamtTopic"/>        
         </enablement>
      </decorator>

在装饰器类中，我设置了可以正常工作的装饰后缀:

In the decorator class i set the decoration suffix which works fine:

public class TopicDecorator extends LabelProvider implements ILightweightLabelDecorator, {
  ControlMaturityService maturityService = new ControlMaturityService();    
  @Override
  public void decorate(Object element, IDecoration decoration) {
     decoration.addSuffix( new StringBuilder().append(" [")
       .append(maturityService.getWeightedMaturity((IControl)element))
       .append("]").toString() );   
     decoration.setForegroundColor(new Color(Display.getCurrent(), 150,90,90));     
   }

如您所见，我还尝试设置没有效果的足够的前景色.后缀与树中的标签具有相同的颜色:黑色.

As you can see i also tried to set the foreground color of the suffic which has no effect. Suffix has the same color as the label in the tree: black.

如何设置装饰后缀的颜色?

推荐答案

使用org.eclipse.jface的包装类 TreeElementDecoratingLabelProvider ，我刚刚成功获得了不同的彩色文本修饰.viewers.DecoratingLabelProvider :

I have just had success getting a different coloured text decoration using a wrapper class TreeElementDecoratingLabelProvider for org.eclipse.jface.viewers.DecoratingLabelProvider:

public class TreeElementDecoratingLabelProvider extends DecoratingLabelProvider {
   public TreeElementDecoratingLabelProvider(ILabelProvider provider,   ILabelDecorator decorator) {
      super(provider, decorator);
   }

    @Override
    public Color getForeground(Object element) {
      //return your color for element...
      return Display.getDefault().getSystemColor(SWT.COLOR_GRAY);
   }
}
