Disable when VOPS

[Mcronin]

This should be any easy question. I have a paramter in VOPS I want disabled when a certain toggle variable is false. What's the proper way to format the text in the "Disable When" field of the parameter VOP?

[Dries]

{parametername value}

eg: {MyToggle 0}

You can have several of these pairs.

[Mario Marengo]

{parametername value}

eg: {MyToggle 0}

You can have several of these pairs.

Just to add what Dries said:

Pairs inside a single {} block are ANDed, and different blocks are ORed. So:

{ a 1 } { b 2 } { str "hello" }

will disable if: a==1 OR b==2 OR str=="hello"

and

{ a 1 str "hello" } { b 2 }

will disable if: (a==1 AND str=="hello") OR b==1

Make sense?

Crystal clear, thanks fellers.

Is it possible to disable interface element when nothing connected to second input of custom op?

I have an idea. We can connect Point SOP to second input and use something like

if(!$PTNUM) {
  // nothing connected
  ...
}
else {
  // something connected
  ...
}

But this method looks not clear
