SWT/Jface ControlDecoration 使用

自己留个备份

ControlDecoration decoration = new ControlDecoration(text, SWT.TOP | SWT.LEFT);

decoration.setImage(PlatformUI.getWorkbench().getSharedImages()

.getImage(ISharedImages.IMG_DEC_FIELD_ERROR));

decoration.setDescriptionText("请填写整数");

decoration.hide();

Decoration自带的image

Image image = FieldDecorationRegistry.

getDefault().

getFieldDecoration(FieldDecorationRegistry.DEC_INFORMATION).

getImage();
