Delphi2010　Indyのコンポーネント　2010/11/10

　
前回は[Vista Dialogs]内のコンポーネントについて見てみました。[Vista Dialogs]は、Windows98/Me/NT/2000/Xp では動作しませんので、WindowsVista以降専用のアプリケーション開発を行う場合に利用して下さい。
　
[Vista Dialogs]の次は、[Touch]（タッチ）・[Gestures]（ジェスチャ）が並んでいますが、これは Windows7 で実現されたディスプレイでのマルチタッチ機能を実装するものです。ですのでWindows7 マルチタッチ機能を持つディスプレイが必要となります。そのディスプレイを指やペンで押したりなぞったりする事によってアプリケーションを動作させることが出来ます。　タッチパネルのディスプレイは昔からありますが、指１本で押すって事が基本だったと思われます。しかしこのマルチタッチは、指２本同時押しや、なぞるというジェスチャ機能を持っています。といっても、小さいボタンの上をなぞると言っても無理がありますので、その辺りの使い方・実装は考えないといけないとは思います。取り合えず、ここではパスします。
　
その次に、Indy Project の [Indy Clients]・[Indy Servers]・[Indy I/O Handlers]・[Indy Intercepts]・[Indy Misc]　があります。量が半端ではありませんし私自身も以前 TIdFTP を使った事があるだけでそれ以外は全く分かりません。Delphi6よりもかなり増えているようです。ですのでここでは、どういうコンポーネントがあるのか、だけを書いておきます。以下、ヘルプより（※ヘルプは英語です）。

Delphi6に搭載されていた TIdFTPを利用して FTPプログラムを作成したことがありますが、当時はまだ動作が不安定でした。その後、Delphi7 を導入してから再度、TIdFTPを利用しましたが、動作は安定し、Delphi6の時におかしかった挙動は全く現れませんでした。という訳で、Indyコンポーネントはバージョンによって変わる事もありますから、利用される場合にはバージョンのチェックも行っておいた方が良いかもしれません。
