Styling based on combination of labels [message #1171394]

Hi.
I have grid representing database table and want to mark PK fields with icon.
I defined cell painter decorator and it works great.

configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, new BeveledBorderDecorator(new CellPainterDecorator(new TextPainter(), CellEdgeEnum.LEFT, new ImagePainter(getImage("key.png")))), DisplayMode.NORMAL, LABEL_PK);

The problem is that when I sort by this column the image disappears since sort header has it's own cell painter (SortableHeaderTextPainter). So what I need is to decide on painter based on combination of labels: not pk and not sorted - TextPainter, pk and not sorted - ImagePainter, not pk and sorted - SortablePainter, pk and sorted - SortablePainter decorated with ImagePainter.
Is it doable or there is other way to achieve functionality I need?

You could register a different SortableHeaderTextPainter that does not use a TextPainter but your decorator as interior painter.
And you would need to use an ImagePainter with no initial image set, but configure a style that contains an image.

ICellPainter myDecorator = new CellPainterDecorator(new TextPainter(), CellEdgeEnum.LEFT, new ImagePainter());
SortableHeaderTextPainter sortPainter = new SortableHeaderTextPainter(myDecorator);

configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, sortPainter , DisplayMode.NORMAL, SORT_DOWN_CONFIG_TYPE);
configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, sortPainter , DisplayMode.NORMAL, SORT_UP_CONFIG_TYPE);

//set the image style for the label
Style imageStyle = new Style();
mageStyle .setAttributeValue(CellStyleAttributes.IMAGE, getImage("key.png"));
configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_STYLE, imageStyle, DisplayMode.NORMAL, LABEL_PK);
