Using Lists with forms

All,

Is there a way to "refresh" a list that has changed in a form. For
example, I have (1 2 3 4 5) in a list, I change the list to (1 2 3)
can I "refresh" the form or does the form need to be closed and
brought back up?

Thank you,
Eric

 

Hi Eric,

Have you ever tried to write a callback for it ?

There are couple of useful examples I have bookmarked from previous
posts ...

Eric,

It's not entirely obvious what you're trying to achieve. Is this list a list of
choices in a cyclic field, or is it a list of entries in a list box? Or is it
some list completely outside the form? What triggers the change?

Sorry, more questions than answers... but callbacks could well be the answer, as
Riad said.

Riad and Andrew,

I went home last night thinking I did not give enough information to
articulate what I was trying to accomplish, sorry about that. I did
look over the example and learned a few things, but I am still fuzzy
on how I do what I want.

So, from the code below if I hit "apply" a procedure is called and
with that procedure I want to "refresh"(maybe bad wording) the list
box. How do I do that?

Thank you for your help in advance,
Eric



let((EFDualMode EFSortBy EFNetsBox)

EFDualMode = hiCreateRadioField(
?name 'EFDualMode
?prompt "Sort data by?"
?value "Instance"
?defValue "Instance"
?choices list("Instance" "Cellname" "Pin" "Net")
)
)

EFSortBy = hiCreateStringField(
?name 'EFSortBy
?prompt "Instance, Net, Cellname or Pin"
?editable nil
?value ""
)

EFNetsBox = hiCreateListBoxField(
?name 'EFListBoxField
?prompt " "
?choices EFNet_list
?value nil
?multipleSelect nil
?changeCB "EFprobe()"
?doubleClickCB "EFprobeinst()"
?numRows length(EFNet_list)
)

;;; defines the form

hiCreateAppForm(
?name 'EFInstanceNetsForm
?formTitle "Instance Nets"
?callback "EFSortExecution()"
?fields
list(
EFDualMode
EFSortBy
EFNetsBox
)

) ; hiCreateAppForm
)
hiDisplayForm(EFInstanceNetsForm)

procedure(EFSortExecution()
printf("Procdure to refresh the List Box")
)

 

Eric,

You had a parenthesis in the wrong place, which I fixed (after the EFDualMode
variable definition). I think you want something like this:

let((EFDualMode EFSortBy EFNetsBox)

EFDualMode = hiCreateRadioField(
?name 'EFDualMode
?prompt "Sort data by?"
?value "Instance"
?defValue "Instance"
?choices list("Instance" "Cellname" "Pin" "Net")
)

EFSortBy = hiCreateStringField(
?name 'EFSortBy
?prompt "Instance, Net, Cellname or Pin"
?editable nil
?value ""
)

EFNetsBox = hiCreateListBoxField(
?name 'EFListBoxField
?prompt " "
?choices EFNet_list
?value nil
?multipleSelect nil
?changeCB "EFprobe()"
?doubleClickCB "EFprobeinst()"
?numRows length(EFNet_list)
)

;;; defines the form

hiCreateAppForm(
?name 'EFInstanceNetsForm
?formTitle "Instance Nets"
?callback "EFSortExecution()"
?fields
list(
EFDualMode
EFSortBy
EFNetsBox
)

) ; hiCreateAppForm
)
hiDisplayForm(EFInstanceNetsForm)

procedure(EFSortExecution()
let((currentList)
printf("Procdure to refresh the List Box")
currentList=EFInstanceNetsForm->EFListBoxField->choices
; silly examples of updating the choices
EFInstanceNetsForm->EFListBoxField->choices=reverse(currentList)
;EFInstanceNetsForm->EFListBoxField->choices=cdr(currentList)
)
)

Andrew.

 

Andrew,

It appears I was working hard at making something simple really
complicated.

Thank you very much from saving me from myself,
Eric
