GcApplicationResize クラス

既存の任意のフォームにアタッチすることで、現在のアプリケーションのすべてのフォームを 2 本指のタッチでサイズ変更できるようにするコンポーネントを表します。

構文

Visual Basic (宣言)
C#

Public Class GcApplicationResize 
   Inherits System.ComponentModel.Component

public class GcApplicationResize : System.ComponentModel.Component

解説

GcApplicationResize は現在のアプリケーションのすべてのフォームを検出し、見つかったフォームに GcResize コンポーネントをアタッチします。アタッチする前に、GcApplicationResize はその固有の設定によって GcResize の設定を初期化します。その後で、GcResizeAttaching イベントと GcResizeAttached イベントを発生させます。ユーザーはこのイベントのイベントハンドラで初期設定を変更できます。また、GcResizeAttaching イベントで GcResizeAttachingEventArgs の GcResizeAttachingEventArgs.Cancel プロパティを true に設定することにより、アタッチをキャンセルすることもできます。

フォームにすでに GcResize がアタッチされている場合、GcResize は再びアタッチされません。

GcApplicationResize では、ツールチップ、コンテキストメニュー、およびコモンダイアログにジェスチャによるサイズ変更機能を与えることはできません。

使用例

次のサンプルコードは、GcApplicationResize コンポーネントの使用方法を示します。

このコードを既存の Windows Forms アプリケーションにコピーし、サンプルコードを含むフォームを開始フォームとして設定します。

このコードの実行時にライセンスエラーが発生した場合は、ツールボックスから任意のフォームに GcApplicationResize コンポーネントをドラッグしてみてください。そうすると、このプロジェクトにライセンス情報が生成されます。
