float over both text and margin

float over both text and margin

[Vit Zyka]

Hi.

1) I am unsuccessfully solving the problem of making float spanning both 
text and margin. More over, it is inside columnset... Example follows. 
Is there some solution?
-----------------------------------------
\showframe
\setupcolors[state=start]
\setuplayout[margin=0pt,rightmargin=1.5cm,width=middle]

\starttext
\startcolumnset
   \dorecurse{2}{\input knuth \endgraf\blank}
   \placefloat[page]{none}
     {\framed
      [width=\dimexpr\makeupwidth+\rightmarginwidth+
                     \rightmargindistance\relax,
       height=\textheight]
      {Here I would like to be a float over both text and margin. How?}
     }
   \dorecurse{10}{\input knuth \endgraf\blank}
\stopcolumnset

\stoptext
-----------------------------------------

2) As a side effect I discover that in the following example the float 
is over the text (so some text is disappeared).
-----------------------------------------
\showframe
\setupcolors[state=start]
\setuplayout[margin=0pt,rightmargin=1.5cm,width=middle]

\starttext
\startcolumnset
   \dorecurse{2}{\input knuth \endgraf}
   \placefloat[page]{none}
     {\framed
        [width=\makeupwidth,height=\textheight,background=screen]
        {Here I would like to be a float over both text and margin. How?}
     }
   \dorecurse{10}{\input knuth \endgraf}
\stopcolumnset

\stoptext
-------------------------------------------

don't use \placefloat.

\definefloat
  [pagefigure]
  [figure]
\setupfloat
  [pagefigure]
  [default={page,none},
   location=inner]

  \dorecurse{3}{\input knuth \endgraf\blank}
  \placepagefigure
      {}
     {...}

etc

maybe the next helps, but i hesitate to include this patch too fast

def\dogetfloat
  {\ifsomefloatwaiting
     \global\setbox\floatlist\vbox
       {\unvbox\floatlist
        \global\setbox\globalscratchbox\lastbox}%
     \ifcenterfloatbox
       \ifdim\wd\globalscratchbox<\hsize
         \setbox\floatbox\hbox to \hsize{\hss\box\globalscratchbox\hss}%
       \else
         \setbox\floatbox\box\globalscratchbox % local !
\wd\floatbox\makeupwidth
       \fi
     \else
       \setbox\floatbox\box\globalscratchbox % local !
     \fi
     \global\advance\savednoffloats \minusone
     \ifcase\savednoffloats
       \global\somefloatwaitingfalse
     \fi
   \else
     \global\savednoffloats\zerocount
     \global\setbox\floatbox\box\voidb@x

or maybe:


\def\dogetfloat
  {\ifsomefloatwaiting
     \global\setbox\floatlist\vbox
       {\unvbox\floatlist
        \global\setbox\globalscratchbox\lastbox}%
     \ifcenterfloatbox
       \ifdim\wd\globalscratchbox<\hsize
         \setbox\floatbox\hbox to \hsize{\hss\box\globalscratchbox\hss}%
       \else
         \setbox\floatbox\box\globalscratchbox % local !
\ifinsidecolumns
    % retain special alignments
    \ifdim\wd\floatbox>\makeupwidth
        \wd\floatbox\makeupwidth
    \fi
\fi
       \fi
     \else
       \setbox\floatbox\box\globalscratchbox % local !
     \fi
     \global\advance\savednoffloats \minusone
     \ifcase\savednoffloats
       \global\somefloatwaitingfalse
     \fi
   \else
     \global\savednoffloats\zerocount
     \global\setbox\floatbox\box\voidb@x
   \fi}

OK, I thought \placefloat[page] is defined like this, but now I see this 
is more flexible.

Thank you for your patch it behaves better but still the float is over 
the text, see page 2 in the example. I also do not see the influence of 
location argument.
