I am trying to generate an EPG grid with cells that contain text. The example above generates the epg grid but the text is underneath the green cell. How can I make the text appear over the drawn object? How could I remove the grid cells for an update to an EPG program data? On a related note, how could I clip the text to appear within the confines of the cell? I don't see anything native for the draw text to enable the use of ellipsis (...). Would this need to be written as extended functionality of the drawText. I've read the 2D API but would love to see some more examples using it.
Thanks for any insight or help.
