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

[Claus W. S. <cws...@ac...>]

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?
