Adding fields to form programmatically

dragank

Hi all.

Is there a way to add string field ("hiCreateStringField") to existing form?

I am trying to do something like:

formFields = plotterForm->fieldList
upToCornerSelection = list()
upToCornerSelection = append1(upToCornerSelection car(formFields))
upToCornerSelection = append1(upToCornerSelection cadr(formFields))
upToCornerSelection = append1(upToCornerSelection caddr(formFields))
afterCornerSelection = cdddr(formFields)

insertionFields = list()
rangeLabel = list(hiCreateLabel(?name 'rangeLabel ?labelText "Range") 200:100 95:28)
insertionFields = append1(insertionFields rangeLabel)

foreach( cvn cornerVariations->?
newStringField = hiCreateStringField(
?name stringToSymbol(strcat("strip" sprintf(nil "%d" rowCounter) "StringField"))
?prompt sprintf(nil "%d" rowCounter)
)
newStringField = list(newStringField 0:100+dY*rowCounter 270:28 100)
insertionFields = append1(insertionFields newStringField)
)

newFieldsList = append(upToCornerSelection insertionFields)
newFieldsList = append(newFieldsList afterCornerSelection)

plotterForm->fieldList = newFieldsList

rowCounter = rowCounter + 1

Thank you in advance.

  • You can't just update the list. You need to call hiAddField or hiAddFields to add them - see this example for details.

    I replaced misused code and now I have:

    dY = 30
    rowCounter = 1
    formFields = plotterForm->fieldList
    upToCornerSelection = list()
    insertionContainer = cadddr(formFields)

    rangeLabel = list(hiCreateLabel(?name 'rangeLabel ?labelText "Range") 0:50 100:28)
    hiAddField(insertionContainer rangeLabel)

    foreach( cvn cornerVariations->?
      newStringField = hiCreateStringField(
                         ?name stringToSymbol(strcat("strip" sprintf(nil "%d" rowCounter) "StringField"))
                         ?prompt sprintf(nil "%d" rowCounter)
                       )
      newStringField = list(newStringField 0:100+dY*rowCounter 270:28 100)
      hiAddField(insertionContainer newStringField)
      rowCounter = rowCounter + 1
    )

     insertionContainer gets evaluated as "hiCreateScrollRegion"  

    I need it as a contained to populate fields programmatically.

    But no luck so far.

    I have CIW Error:

    *** Error in routine error:
    Message: *Error* hiAddField: argument #1 must be a form struct, scroll region, or hiLayout.

    Debugging this without seeing all the code is rather difficult - I suggest you contact customer support. Otherwise we're sailing blind!

    Thanks again.

    I added "dyn_" prefix to dynamically populated fielda, so I can distinct them from static fields.

    This way I can add  them and remove them programmatically  as needed.
