help !! getFormattedExpression() ?????? 2d.editor parameter ???

D2Editor:getFormattedExpression it not a public API (nor is it available in standard Lua, only in QnA Lua).
You may be looking for getExpression instead. This link has an example.

Also, see the official Nspire API PDF.

Help me get the numerical value of a text box to use mathematics in var.store and use that value in another application

ayuda

Code: Select all

local cuadro= D2Editor.newRichText()

function on.paint(gc)
gc:drawString("Valor  =",60,5)
  cuadro:move(125,5)
  cuadro:resize(35,25)
  cuadro:createMathBox()
  cuadro:registerFilter({tabKey = function() cuadro:setFocus(false) end,enterKey = function () cuadro: setFocus(false) end})
  local variable = cuadro:getExpression()
  var.store("salida",variable)
end

If you don't need actual math formatting, just remove the "createMathBox" part. If you do need it, you'll need to filter out the "\0el {" at the start and "}" at the beginning (with string.sub)

Here I recoded your thing (not tested...) to set the Basic variable "salida" only when pressing the enterKey

Code: Select all

function on.construction()
    cuadro = D2Editor.newRichText()
    cuadro:move(125, 5)
          :resize(35, 25)
          :setBorder(1)
          :setFocus(true)
          :registerFilter( { tabKey = function() cuadro:setFocus(false) end,
                             enterKey = function() cuadro:setFocus(false) var.store("salida", cuadro:getExpression()) end } )
end

function on.paint(gc)
    gc:drawString("Valor  =", 60, 5)
end

Don't do anythign else than drawing inside the on.paint(gc) method.

gracias... otra pregunta




comando ???

Interesting, I suppose they forgot to remove it from there....

gracias por sus respuestas
me podría dar algún consejo de como estructurar este código ??

soy novato en esto

You could move all the editors' move/resize/registerFilter in the on.resize function or on.construction (that's a function only called once)
You should NOT use on.paint (or functions called from on.paint) for anything else than drawing, so those should not be in there, it will slow everything down.
