How to paint multiple images in a cell. [message #1679929]

I am struggling to get to paint multiple images in one cell. Some cells need one icon and some cells need two icons. So I set labels accordingly to the cells. And I set the Image Painters such that one painter paints the image to the left and another to the top.

But at a time only one image is being painted. The Label which NatTable finds first is the corresponding image that it is displaying. Is there a way to paint multiple images in the same cell?

	@Override
	public void accumulateConfigLabels(LabelStack configLabels, int columnPosition, 
			int rowPosition) {
		if(dataProvider.hasImage(columnPosition, rowPosition)){
			configLabels.addLabel(NatTableLabelConstants.CELL_WITH_IMAGE);
		}
		
		List<String> labels = dataProvider.getLabels(columnPosition, rowPosition);
		
		if(labels!=null ){
			for(String label: labels){
				configLabels.addLabel(label);
			}
		}
}

ImagePainter imagePainter = new ImagePainter(mStyle.getRejectedCellImage(), true);
			CellPainterDecorator imageDecorator = new CellPainterDecorator(beveledDecorator, CellEdgeEnum.TOP, imagePainter);
			configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, imageDecorator, DisplayMode.NORMAL, OrdersNatTableLabelConstants.CELL_WITH_REJECTED_IMAGE);

ImagePainter imagePainter = new ImagePainter(style.getCellImage(), true);
			CellPainterDecorator imageDecorator = new CellPainterDecorator(beveledDecorator, CellEdgeEnum.LEFT, imagePainter);
			configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, imageDecorator, DisplayMode.NORMAL, NatTableLabelConstants.CELL_WITH_IMAGE);

natTable.addConfiguration(new NatTableConfiguration(mStyle));

This is because you configured two different painters. There is only one cell painter active at a time. If you want to show multiple painters at a time, you need to combine them via CellPainterDecorator.

That said, either you add a third label to indicate that both icons should be shown and register a CellPainterDecorator that decorates your first decorator, or you implement a custom painter that inspects the labels itself and delegates according to that.

I am now able to paint two images. I added all the labels and removed CELL_WITH_IMAGE label if there is a REJECTED_IMAGE label and did a CellPainterDecorator. I did one image on top and other on left. Is there is a way where I can do both images side by side and text like [image1][image2] [text] kind of in the same cell?
