Hi, I've tried Hans' example introduced at mwidget-p.pdf, it's perfect. But when I was trying some subpage arrangements, it just failed. How could it happen? I guess either shiping out subpages forget the fields or something has covered over them. Here's a small example (by the way, I don't actually know the meanings of the arguments of \dosetuparrangement, I'm very appreciated if someone could explain the macro to me.): ========================================================= \setupinteraction [state=start] \installpagearrangement TEMP {\dosetuparrangement{1}{1}{1}{0}{0}% \pusharrangedpageTEMP\poparrangedpagesAonly\relax} \def\pusharrangedpageTEMP#1% {\doglobal\increment\arrangedpageN \reportarrangedpage\arrangedpageN \ifcase\arrangedpageN \or \handlearrangedpageXandY{#1}0{11}0\arrangedpageA \or \handlearrangedpageXandY{#1}0{9}0\arrangedpageA \or \handlearrangedpageXandY{#1}0{7}0\arrangedpageA \or \handlearrangedpageXandY{#1}0{5}0\arrangedpageA \or \handlearrangedpageXandY{#1}0{3}0\arrangedpageA \or \handlearrangedpageXandY{#1}0{1}0\arrangedpageA \poparrangedpages \fi} \def\poparrangedpagesAonly {\ifnum\arrangedpageN>\zerocount \dontcomplain \paperwidth\arrangedpageX\paperwidth \paperheight\arrangedpageY\paperheight \outputarrangedbox\arrangedpageA \doglobal\newcounter\arrangedpageN \fi} \definepapersize [Column] [width=40pt, height=400pt, offset=0pt] \definepapersize [Scroll] [width=540pt, height=400pt, offset=0pt] \setuppapersize [Column][Scroll] \setuparranging [TEMP,background] \setuplayout [margin=0pt, width=fit, height=middle, leftmargin=0pt, rightmargin=0pt, leftedge=0pt, rightedge=0pt, header=0pt, footer=0pt, bottom=0pt, top=0pt, backspace=0pt, topspace=0pt, bottomspace=0pt, horoffset=0pt, veroffset=0pt, headerdistance=0pt, footerdistance=0pt, topdistance=0pt, bottomdistance=0pt] \pdfoptionpdfminorversion=6 \title{What?} \starttext \newcounter\abc \doglobal\increment\abc \setupfields [reset] \setupfield [HelpSetup] [width=1.2em,height=fit,frame=off,option={readonly,hidden}] \def\currenthelp{Help::\abc} \definefield [\currenthelp] [check] [HelpSetup] [helpinfo\abc] [helpinfo\abc] \definesymbol [helpinfo\abc] [\SomeHelpText] \def\SomeHelpText% {\framed [width=1.2em,height=fit,align=middle,style=small, frame=on,background=color,backgroundcolor=white,framecolor=red] {Some texts}} \inright{\fitfield[\currenthelp]} Click \goto{here}[JS(Toggle_Hide{\currenthelp})] to see. \dorecurse{10}{\input knuth\endgraf} \stoptext ========================================================= -- Sincerely yours, Chen ---------------------------------------------------------------- Zhi-chu Chen | Shanghai Synchrotron Radiation Facility No. 2019 | Jialuo Rd. | Jiading | Shanghai | P.R.
