Field to display all nets in layout and filter as I type

Hi Prasad,

The hiCreateComboField function lets you define a modifyCallback that is triggered whenever a change is made in the field. I haven't tried this out myself yet but reconfiguring the choices of the combo field in that callback should work.

I just found a piece of example code that does the job...

let((cf (cv (geGetWindowCellView)) )
    cf=hiCreateComboField(
        ?name 'cf
        ?items cv~>nets~>name
        ?modifyCallback
            lambda((field form value flag)
                let((len)
                    len=strlen(value)
                    form->cf->items=setof(item form->cf->allItems
                        strncmp(item value len)==0) t)))
    cf->allItems=cf->items
    hiCreateAppForm(
        ?name 'CCFform
        ?fields list(cf))
    hiDisplayForm(CCFform))

Hi Max, Thanks for the quick reply. Adding modifyCallback function as you suggested is filtering the net names. But I want to have more interactive drop down menu just like in leCreateNetField, where the drop down menu highlites the net names that matches with the net name that we are typing. 

Do you know if there is a way to add an option to leCreateNetField to allow it to take new inputs as well? 

Thanks,
Prasad 

Hi Prasad,

The leCreateNetField is completely custom made by Cadence so you won't have the possibility to tweak it

Here is a quick overview of what is inside the different fields:

;; -------------------------------------------------------
;; Combo Field
;; -------------------------------------------------------

> (hiCreateComboField ?name 'combo_field ?items (geGetEditCellView)~>nets~>name)
comboStruct@0x3dfed6e0

> comboStruct@0x3dfed6e0->?
(_focusInCallback usedIn invisible items highlightType
    nextField enabled editable echoOn prompt
    _formatSpec _modifyCallback _callback fieldType hiFieldSym
    modified defValue lastValue _activeUT value
)

;; -------------------------------------------------------
;; Net Field
;; -------------------------------------------------------

> (leCreateNetField 'nets_field ?window (hiGetCurrentWindow))
nativeStruct@0x3dfed6f8


> nativeStruct@0x3dfed6f8->?
(usedIn invisible enabled _userData _factory
    prompt fieldType hiFieldSym _activeUT
)

> nativeStruct@0x3dfed6f8->_userData
(leNetComboBoxNative name "leNetComboBoxNative" value ""
    window window:3 callback "" maxVisibleItems
    10 enabled nil invisible nil
    maxWidth 0
)

;; -------------------------------------------------------
;; Layer Field
;; -------------------------------------------------------

> (leCreateLayerField 'layer_field ?techFile (techGetTechFile (geGetEditCellView)))
nativeStruct@0x3e24d9e0

> nativeStruct@0x3e24d9e0->?
(usedIn invisible enabled _userData _factory
    prompt fieldType hiFieldSym _activeUT
)

> nativeStruct@0x3e24d9e0->_userData
(leLPPComboBoxNative name "leLPPComboBoxNative" value ""
    callback "" appendChoices nil prependChoices
    nil maxVisibleItems 10 syncedPaletteWindow nil
    techFile db:0x2454c01a layerFunction "" enabled
    nil invisible nil maxWidth 0
)

As you can see, there is not much _userData available in the leCreateNetField to customize it

You could request an enhancement of the combo fields to make them more interactive. This would be a nice feature as they are often used

Hope this helps you a little

Cheers,
