change default GUI callback

Leonid Y

Hello guys,

 I am a bit new to skill programming. I would like to change default behaviour of a standard form. Basically I would like one field to change its value when another field is modified in a default form. To be more specific, I want some exact values to be set in "Create Instance"  dialog for the "Delta X", "Delta Y" fields when a particular Lib Cell View is chosen.

I have found out that the form is bound to  the leCreateInstForm structure and it , in turns, has the fields: libName cellName viewName instName and so on; Each one has a list of properties including more interesting for me:

 _focusInCallback

 _modifyCallback

_callback

The values of first two properties are empty "" and the last one is set to

 "leInstCellNameCB(leCreateInstForm~>cellName~>value)"

which I suppose default skill routine which checks for cellview existence  in Library Manager and something else. I guess it is exactly where the things happen.

Till this moment everything seems to be clear, but when I replace  the default routine with my own one , which does just perfect when it is fed to CIW , it not only does not do what I expect but the whole mechanism seems to get broken till I restart icfb.

So, my questions :

- is it possible in general to change default behaviour in my case? some straight ways or tricky ones.

- what does the underscore  sign in the beginning of _callback property mean? There must be some special meaning..

    What if you wrap it with a hiRegTimer call to update the deltas right after the form comes up? You would setup your bindkey for placing an instance like this:

    hiRegTimer("myInstCallback()" 1) leHiCreateInst()

    This would initiate your callback one tenth of a second after the form comes up.
