Hi, > As far as I can tell, y isn't used or displayed in these solutions > and isn't defined outside the panel, so what's all that "assign" > gyration about? yes, but that's not of interest for the problem. Even if you do display the stuff it doesn't work and I assume the example was just an artificial minimal one. DynamicModule[{x, y, assign}, assign := (y = x); Column[{ Checkbox[Dynamic[x, (x = #; assign;) &], {True, False}], Dynamic[{x, y}] } ], Initialization :> (x = True; assign) ] DynamicModule[{x, y, assign}, assign[] := (y = x); Column[{ Checkbox[Dynamic[x, (x = #; assign[];) &], {True, False}], Dynamic[{x, y}] } ], Initialization :> (x = True; assign[]) ] Cheers Patrick > Bobby > > On Wed, 20 Jan 2010 05:46:01 -0600, Patrick Scheibe = <pscheibe at trm.uni-leipzig.de > > wrote: > >> Hi, >> >> it matters that your assign and initialize functions have DownValues. >> >> Panel@DynamicModule[{x, y, assign, initialize}, >> Grid[{{"", "A", "B"}, {"w/ assign:", >> RadioButton[Dynamic[x, (x = #; assign[]) &], True], >> RadioButton[Dynamic[x, (x = #; assign[]) &], >> False]}, {"w/o assign:", RadioButton[Dynamic@x, True], >> RadioButton[Dynamic@x, False]}, {"value:", Dynamic@x}}, >> Dividers -> {False, {False, True, True, True, False}}, >> Alignment -> {Left, {Center}}], >> Initialization :> (assign[] := (y = >> x);(*further variables to update*) >> initialize[] := (x = True; assign[]);(*initialization = function*) >> initialize[];)] >> >> Cheers >> Patrick >> >> >> On Tue, 2010-01-19 at 05:14 -0500, Istv=C3=A1n wrote: >>> Dear Group, >>> >>> I have some problem with a complex interface inside a DynamicModule. >>> This is a toy version of the program, which can fully reproduce the >>> malfunction: >>> >>> Panel@DynamicModule[ >>> {x, y, assign, initialize}, >>> >>> Grid[{ >>> {"", "A", "B"}, >>> {"w/ assign:", RadioButton[Dynamic[x, (x = #; assign) &], = True], >>> RadioButton[Dynamic[x, (x = #; assign) &], False]}, >>> {"w/o assign:", RadioButton[Dynamic@x, True], >>> RadioButton[Dynamic@x, False]}, >>> {"value:", Dynamic@x} >>> }, Dividers -> {False, {False, True, True, True, False}}, >>> Alignment -> {Left, {Center}}], >>> >>> Initialization :> ( >>> assign := (y = x);(* further variables to update *) >>> initialize := (x = True; assign); (* initialization function = *) >>> initialize; >>> ) >>> ] >>> >>> Now for some reason, the radiobuttons do not function as intended = >>> (at >>> least as I want). >>> The following clicking orders do not work: >>> >>> [w/ + B] then [w/ + A] >>> [w/o + B] then [w/ + A] >>> >>> these work correctly: >>> >>> [w/ + B] then [w/o + A] >>> [w/o + B] then [w/o + A] >>> >>> I guess, that the problem is with the "initialize" (or the "assign") >>> function.
