Cell Text Formatting in Nattable [message #1709254]

Hi,
I am using CustomLineBorderDecorator with Textpainter for Cells of some Columns to draw line either to left side or top of the Cell in Nattable,

configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, new CustomLineBorderDecorator(new TextPainter(), new BorderStyle(1, GUIHelper.COLOR_BLUE,
                        LineStyleEnum.SOLID)),DisplayMode.NORMAL);

Now the text of cells of one of these Columns whose rows are spanned i have to format like below :

First Line Of Cell
Second Line of Cell
Third Line of Cell

How it can be done ??

I found RichTextCellPainter from latest Nattable SNAPSHOT.

But When I applied it I got two Problems:
- spanned cell border is appearing, and
-after mouse click text of the cell is disappearing

What should I do to fix this and How RichTextCellPainter be used to get above Format???

I don't understand what you mean with that. What border? Where? How does your labels look like?

Is there an editor involved? Otherwise I don't understand why text should vanish on click. It doesn't in the examples.

The RichTextCellPainter is able to format HTML markup code. So you need to add the necessary tags. This can for example be done via MarkupDisplayConverter.

I think you need to checkout the sources to get the details and have a look at the example in _424_NebulaRichTextIntegrationExample.

I suppose you are talking about the gray lines? You should wrap the RichTextCellPainter in a BackgroundPainter. The current implementation of TextCellPainter is itself a BackgroundPainter (which is IMHO not the best design regarding the painters and might be changed in the future).

Thank you very much... after wraping with BackgroundPainter everything is working fine.
