extendscriptのパスから再帰的にツリービューを作成する

Question

Adob​​e After Effectsのextendscript関数では、以下のようなファイルパスのリストをツリービューに変換する必要があります。ここまでは私のコードですが、それは最初の "レベル"の罰金を歩いていますが、私は再帰に問題があります。助けが大変ありがとうございます、私はこれに対して私の頭を打っていて、まだそれを働かせるように見えません！

    var stImporterWin = new Window("palette", "ST Import Panel", undefined, {resizeable:true});

私は再帰を除去することによって、あなたのコードを少し単純化。あなたが階層を歩いていないので必要ありません。各パスに階層があります。

    var stImporterWin = new Window("palette", "ST Import Panel", undefined, {resizeable:true});

    imageSequenceGroup.alignment = ["fill", "fill"]; 
    imageSequenceGroup.orientation = "column"; 
    var imageSequenceTree = imageSequenceGroup.add("treeview"); 
    imageSequenceTree.preferredSize = [600,650]; 
    imageSequenceTree.alignment = ["fill", "fill"];
