Select/refer to brushes by name within brush sets by name

  • August 11, 2018

New question from me:

Is it possible to do the following items when it comes to Ps scripting?

  1. List all brush sets and their brushes in an array
  2. Obtain last-selected brush and its parent set.
  3. Obtain last-selected brush set if no brush is selected within.
  4. Select a brush by name within a parent set (so as to be able to traverse brushes of same name in different sets.
  5. It's possible to nest brush sets.. is it possible to do all of the above considering the tree-view structure?

      I doubt you can use Action Manager to list Sets of Brushes. Probably you can do it only by reading binaries of .abr files.

      Hmm, at least in Illustrator there's a Brushes and a Brush objects which can be used to create & apply brushes - but more fundamentally to see the brushes in the brush panel and have a list of them. However this is all mostly due to how Illustrator only deals with document-specific palette items, as in, when the document switches, the brushes are all different now. In Ps, it appears to be app-centered and I guess not so easily accessed.

      I wonder how the Ps pros deal with the brush panel contents for when there's a need to use different brushes - in those hypothetical situations where someone may have identically-named brushes in separate sets.

      I did a test with a "select brush by name" function from these forums (Re: Is it possible to cycle through brushes (tpls) using a script? ).

      What it does is select the 1st brush named some name, that happens to be toward the top in the brush panel.

      "Toward the top" in this case means regardless of nesting order: a brush in a single-nested-group set which is located below a same-named brush in a multiple-nested set which is below the single-nested set will not get selected, rather the group above it with multiple nested groups and the named brush in it will get selected.

      That's what I found out so far!

      I tried some time ago and found there is limited access to sets. You can do some basic operation on them like deleting when one is selected (not selected by script) - but that is all. You can do more with sole brushes until you refer them to their sets.
