When does le1ViaForm get created?

I have some bindkey code that cycles through the a specified list of via types (potentially all the via types in the technology) while the Add Via enterfunction is active. The code sets le0ViaForm->viaSingleModeScrollView->viaDefName->value.

I noticed that it stopped having any effect, but I could still change the via type the original way by bringing up the via form using F3 during the add-via command, then setting the via type value in the GUI using the cyclic field. However, looking at the CIW when I did this, I noticed it was setting le1ViaForm->...... . I changed the code temporarily to affect le1ViaForm instead of le0ViaForm and it works as expected.

I couldn't find any reference to le1ViaForm in Cadence help or in the forums. What creates it and when? What's the right way to modify the bindkey code to deal with the new form? Just check for le1ViaForm, or could there also be le<n>ViaForm? Should I set all of them from 0 on up, or just the one with the highest number?

Thanks

The form is technology file specific, so you can get more than one via form depending on if you have more than one tech lib (so it could happen if you have incremental technology databases too). There's an API to get all the layout forms, and you can retrieve the current via form with:

theForm=leGetTechFormList(techGetTechFile(geGetEditCellView()))->viaForm

If you need the symbol for the form, it's then: theForm->hiFormSym

Regards,

Andrew.
