Maintaining two exclusive lists

I'm not sure I quite get what you're asking (I can guess, but I might be guessing wrong). Perhaps a picture of what the form looks like, what it does now and what you're expecting it to do?

Hi Andrew,

Here is a picture of my GUI. I want to move selected elements back and forth from pin list listBoxField to selection bin listBoxField. The above procedure is the callback implementation of move buttons. I swap scrField and dstField to move left to right and vice versa. Things works but when there are duplicate entries in the listBox, the above callback is not able to handle and maintain only unique ones since I have used member function.

Overnight I got another idea by maintaining the list box entries unique by appending with pin's bBox which works fine. But still wondering how to do if entries are not unique.

Thanks

Ramakrishnan,

How about something like this?

procedure(moveBin(scrField dstField)
let((scrList dstList usedCount)
    scrList = hiGetListBoxValue(scrField)
    usedCount = makeTable('usedCount 0)
    dstList = dstField->choices
    foreach(ele scrList
        dstList = cons(ele dstList)
        usedCount[ele] = usedCount[ele] + 1;
    )
    dstField->choices = dstList
    scrList = setof(x scrField->choices 
        if(zerop(usedCount[x]) then
            t
        else
            usedCount[x] = usedCount[x] - 1
            nil
        )
    )
    scrField->choices = scrList
))

Regards,

Andrew.

Hi Andrew,

Thanks for the solution. I have never thought of using a if-else block inside setoff. Something new I learnt.

On a related topic, I see some trouble in doing multiple selection by dragging or holding shift in a list box when the entries are duplicate. The selection does not happen continuous, there are few unselected items in between. Is it a known issue? I am using  virtuoso version ICADV12.3-64b 12/04/2018 18:23.

Thanks again

Hi Ramakrishnan,

Yes, I see that slightly odd behaviour too. I thought something felt odd yesterday when I was trying this out, but I didn't play with it long enough to notice what wasn't right. I suggest you contact customer support with an example to get this fixed...

Regards,

Andrew.

Cadence case https://support.cadence.com/COSCaseDetailPage?CaseID=5000V00001JASMqQAP&pageName=COSCaseDetailPage&isNewCase=false&oMenu=46364198

is created. Thanks for the support here.

For completeness (should anyone else hit the same issue), the answer is to use ?valueByPosition t when creating the listbox field (I tried, and that solves it). The documentation is going to be updated to make this clear as being the correct approach when you have duplicate entries in the listbox fields.

Regards,

Andrew.

Thanks Andrew.

Just out of curiosity:  Is the new updated documentation is available only with new Virtuoso versions or Cadence can do a background push to update the docs in my company?

Hi Ramakrishnan,

The documentation change hasn't happened yet for a start, but when it does, it would be updated on support.cadence.com and in any new hot fix version you install. There is no mechanism to push anything to you (including documentation updates).
