Bitmap in xbrowse column

[wartiaga]

Hi,

Is it possible to display a bitmap at the end of an xbrowse column where it contains the number of a document but which will only be displayed if another file contains the number of that document? How can I do this?
The Column:

oCol:= Lista0:AddCol()
oCol:bStrData := { || ARQBOL->BOLETO}
oCol:cHeader := "BOLETO"


Thanks.
