이 문제는 Image를 swt가 인정할 수 있는 이상 생성하여서 발생한다.
이럴때 해결법은 ImageDescriptor를 통해 createImage 하는 부분을 찾아서 ImageRegistry를 이용하여 이 레지스트리에 이미지를 등록하고, 가져다 쓰는 방식으로 해결한다.
Image image = getImageRegistry().get(path);
if(image==null) {
ImageDescriptor imgDesc = AbstractUIPlugin.imageDescriptorFromPlugin(QualityEditPlugin.INSTANCE.ID,
"icons/" + path + ".gif");
image = imgDesc.createImage();
getImageRegistry().put(path, image);
}
return image;
특히 gmf 의 dashboard를 통해 모델이 자동생성될 때 각각의 라벨 아이콘 생성 코드가 다음과 같이 자동생성된다.
/**
* @generated
*/
protected Image getLabelIcon() {
ImageDescriptor descriptor = QualityDiagramEditorPlugin.getInstance()
.getItemImageDescriptor(getParserElement());
if (descriptor == null) {
descriptor = ImageDescriptor.getMissingImageDescriptor();
}
return descriptor.createImage();
}
이 부분을 다음과 같이 변경한다.
protected Image getLabelIcon() {
return QualityDiagramEditorPlugin.getInstance().getItemImage(getParserElement());
}
public Image getItemImage(Object item) {
IItemLabelProvider labelProvider = (IItemLabelProvider) adapterFactory.adapt(item, IItemLabelProvider.class);
if (labelProvider != null) {
Image image = getImageRegistry().get(((Part) item).getSourceId());
if (image == null) {
ImageDescriptor descriptor = ExtendedImageRegistry.getInstance().getImageDescriptor(labelProvider.getImage(item));
getImageRegistry().put(((Part) item).getSourceId(), descriptor.createImage());
}
return image;
}
return ImageDescriptor.getMissingImageDescriptor().createImage();
}
