Question

I am placing image in a column depending on the status of a boolean value.

col = new TableViewerColumn(this, SWT.NONE);
  col.getColumn().setWidth(70);
  col.getColumn().setText("Print Status");
  col.setLabelProvider(new ColumnLabelProvider() {
  @Override
  public Image getImage(Object element) {
    if (((AplotResultsDataModel.ResultsData) element).isSuccess()) {
      return SUCCESS;
    } 
    return FAIL;
    }
  }); 

Here is the getImage method

private static Image getImage(String file) {
  Bundle bundle = FrameworkUtil.getBundle(Viewer.class);
  URL url = FileLocator.find(bundle, new Path("icons/" + file), null);
  ImageDescriptor image = ImageDescriptor.createFromURL(url);
  return image.createImage();
} 

I have tried two ways of creating the image.

private static final Image FAIL = getImage("failed.png");

And

final Image FAIL = new Image(Display.getDefault() ,"D:/Users/workspace/com.aplot/icons/failed.png");

In both cases the image does display but there is a text path beside it. The path looks like it is the array value for that column.

EXAMPLE:

[image] com.aplot.datamodel.ResultsDataModel$ResultsData@9cce9

How can I remove the text and only show the image?

Answer 1

Override getText() method in ColumnLabelProvider and return empty string. if you dont override, it is always display element.toString(). thats why you see toString() value of your data object there.
