< Visuals | Interaction >
You find more about interactive elements in Widgets uncovered and core-fld.tex.
At the moment all of the following examples are from mwidget manual. We will cook up our own later.
For PDF is only an interface, you need JavaScript to handle interaction (field input etc.).
JavaScript
\startJSpreamble {name} MyCounter = 0 ; \stopJSpreamble \startJScode {increment} MyCounter = MyCounter + 1 ; // or: ++MyCounter ; \stopJScode \goto {advance by one} [JS(increment)]
You can pass values to a JS function:
\startJScode {increment} MyCounter = MyCounter + JS_V_1 ; \stopJScode \goto {advance by five} [JS(increment{V{5}})]
- V{} is verbose, defaults to string
- S{} = as string
- R{} = as reference
- JS_V_n, JS_S_nm JS_R_n are the names of the variables
- JS_N keeps the number of arguments
Fields
Text Entries
see
\fillinfield[name]{text that defines field length} % or \definefield [Email] [line] [ShortLine] [] [sample@contextgarden.net] \field [Email] [your email]
\definefield[name][type][setup name][?don't know?][default content]
\field[name][?don't know?]
Radiobuttons
Sample from the manual:
\setupfield [LogoSetup] [width=4cm, height=4cm, frame=off, background=screen] \definefield[Logos] [radio] [LogoSetup] [ConTeXt,PPCHTEX,TeXUtil] [PPCHTEX] \definesubfield [ConTeXt] [] [ConTeXtLogo] \definesubfield [PPCHTEX] [] [PPCHTEXLogo] \definesubfield [TeXUtil] [] [TeXUtilLogo] \definesymbol [ConTeXtLogo] [{\externalfigure[mpcont.502]}] \definesymbol [PPCHTEXLogo] [{\externalfigure[mpcont.503]}] \definesymbol [TeXUtilLogo] [{\externalfigure[mpcont.504]}] \hbox to \hsize{\hss\field[ConTeXt]\hss\field[PPCHTEX]\hss\field[TeXUtil]\hss}
Checkboxes
\setupfield[setup 3] [width=2cm, height=2cm, rulethickness=3pt, corner=round, framecolor=red] \definesymbol [yes] [{\externalfigure[mpcont.502]}] \definesymbol [no] [] \definefield [checkme][check] [setup 3] [yes,no] [no] \field[checkme]
Tricks
This helps debugging:
\tracefieldstrue \showfields % typeset a table of field relations \logfields % logs field descriptions to a file fields.log
