アラートダイアログ上にNSBrowserを表示するAppleScriptの試作品です。
# 本Scriptは実験用であって実用性はありません(^ー^;;
Finderに使われていることで認知度は高いものの、使いどころが難しいうえにサンプル・コードも多くないので登場頻度が少ないNSBrowserです。(Mac OS Xの前身である)NEXTSTEPのFile Managerがこんな感じのUIでした。
(個人的に)敷居の高かったNSBrowserも、いろいろ試してみたらいい感じになってきました。現状では単に2次元配列っぽいものにアクセスしているだけですが、ツリー型の構造データを与えるようにするとか、配列から徐々にデータ抽出する(大分類→中分類→小分類)ようにすれば、だいたい期待どおりの動作になるはずです。
NSBrowserも、使いたいときに調べると情報が見つからずに困りますが、用のないときなら調べておくといろいろ大丈夫そうです。
macOS 10.14上のスクリプトエディタ/Script Debugger上で動くようにハンドラをメインスレッド上で明示的に動作させるように変更しましたが、10.14上でだけ独特な挙動があるため要注意です。ただ、テストプログラムなのでそんなものだろうかと。
