Hello, This may be a very trivial question to ask, but it has blotted me for a lot time. When I try to set the background or foreground colour for a widget, for example, a label using the following, XtSetArg(arg[i],XtNbackground, "blue"); i++; ... XtSetValues(label, arg,i); or in Motif XtSetArg(arg[i],XmNbackground, "blue"); i++; ... XtSetValues(label, arg,i); The background colour of the label widget just doesn't seem to be set to the colour stated, in this case, "blue". What do I have to do to make this to work? Thanks, Ghee Teo

Either invoke a type converter to convert the string to a pixel value (i.e. XtConvertAndStore in R4, XtConvert in R3) or use the new varargs interface XtVaSetValues and use an XtVaTypedArg. My recently-published book has an extensive section on this. I recommend it highly :-). -paul asente asente@adobe.com ...decwrl!adobe!asente
