hi,

Martin Schmidt started a programm with the monochome option (prog -monochrome)
and wondered why Style::value_is_on ("monochrome") is false.

There is NO styleattribute named "monochrome".
"monochrome" is an attributevalue of attribute "gui"
(see ../iv/src/lib/InterViews/session.c")

      static OptionDesc defoptions[] = {
      .
           { "-monochrome", "*gui", OptionValueImplicit, "monochrome" },
      .
      .
      };


So, "prog -monochrome" is the same as "prog -xrm gui:monochrome".
(-xrm option see IV-RefMan V3.1Beta, table 1.1)


This programm prints "mono is on", when
*   -monochrome or -xrm gui:monochrome option is used,
*   or file "prog" in ../app_defaults is containing   *gui: monochrome
*   or proplist contains {"*gui", "monochrome"} (remove all /* and */ )

#include <stdio.h>
#include <InterViews/session.h>
#include <InterViews/style.h>

/* static PropertyData proplist[] = {
       {"*gui","monochrome"},

       nil
   };


   static OptionDesc options[] = {
   };
*/

int main(int argc, char** argv)
{
    Session* session = new Session("prog", argc, argv /* optlist, proplist */ );
    


    Style *style = session->style();

    String val;
    if (style_->find_attribute("gui",val))
	if (val==String("monochrome"))
	    printf ("mono is on\n");
    
    ...
}
