Toggle Instances Selectable With One Bindkey

buttonGuy
buttonGuy over 10 years ago

Hello,

I am new to skill and my problem is as follows: in Layout, there is an Objects palette that contains the visible & selectable options for Shapes, Instances, Fluid Guardring, Mosaic, Pins, Vias, etc. I want to be able to toggle the Selectable checkbox of the “Instances” with the use of a single bindkey. Currently, I have two bind keys set to make it selectable and not selectable:

z bindkey: _pteHiObjectSetSelectability(dwindow(‘pteObjectPalette2) “Instances” nil)·

Shift+z bindkey: _pteHiObjectSetSelectability(dwindow(‘pteObjectPalette2) “Instances” t)

Any suggestions would be greatly appreciated.

 Thanks!

    Ted,

    I tend to use the if() function without the then and else clauses, because it's more the LISP way. Also in ancient history (before the byte code compiler, which was introduced about 21 years ago, so I can probably move on now), it was noticeably less efficient - nowadays it makes no difference.

    It's very compact to treat it like the C ternary operator, particularly when you're using the return value of the if() - so you can do:

    (setq result (if (equal input 23) "hello" "world"))

    Which is like the C result=(input==23?"hello":"world"). 

    I can see your point that if you only had a then clause, and started with:

    if(someCondition
      doSomething
    )

    and then changed it to:

    if(someCondition
      doSomething
      doSomethingMore
    )

    then you might be confused as to why doSomethingMore wasn't happening. However, you should have used when() in this case. If you had:

    if(someCondition
      doSomething
      otherWiseDoThis
    )

    and then added another statement at the end, it doesn't execute them as the true clause - it gives an error:

    > if(t println(1) println(2) println(3))
    *Error* if: too many arguments (missing then?) - (t println(1) println(2) println(3))

    Andrew.
