There isn't a straightforward way to do this in FOX 1.0. You could 
conceivably do it by subclassing FXTableItem and overriding its 
drawContent() method, but that is much more problematic than it should 
be. Hopefully, Jeroen will address some of these limitations in FOX 1.2.

I don't know if it still applies - It was posted in December of last

Subject: [Fxruby-users] Setting individual cell color with
FXTableItem::drawBackground( )?


I've recently begun working a bit with FXRuby. While messing around with

the code for Tables, I found out that I cannot set individual cell 
colors with FXTable::setCellColor . Now, looking at the API I noticed 
that FXTableItem has an instance method called drawBackground, with the 
parameters table, dc, x, y, w, h. I am assuming that dc is a FXDC 
object, table the parent table of the FXTableItem in question, x and y 
coordinated in pixels, and w and h width and height in pixels. So I 
figured that I could possibly set individual cell color with something 
along the lines of
    @table.getItem( row, col ).drawBackground( @table, dc, x, y, w, h )
However, my attempts so far have been in vain. I've attempted to get x, 
y, w, and h by using
    @table.getColumnX( col ),
    @table.getRowY( row ),
    @table.getItem( row, col ).getWidth( @table ), and
    @table.getItem( row, col ).getHeight( @table ) respectively. I
wasn't sure what to use for dc, so I created a new FXDC 
by using
    dc = FXDC.new( self )
(which didn't work if I recall correctly). So my question is, is it even

possible to use FXTableItem.drawBackground or am I on a futile quest? If

it is possible, what should I use for dc?
