SplitContainer.OnSplitterMoving メソッド

メモ : このメソッドは、.NET Framework version 2.0 で新しく追加されたものです。

SplitterMoving イベントを発生させます。

名前空間: System.Windows.Forms
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)
構文

Visual Basic (宣言)

Public Sub OnSplitterMoving ( _
    e As SplitterCancelEventArgs _
)

Visual Basic (使用法)

Dim instance As SplitContainer
Dim e As SplitterCancelEventArgs

instance.OnSplitterMoving(e)

public void OnSplitterMoving (
    SplitterCancelEventArgs e
)

C++

public:
void OnSplitterMoving (
    SplitterCancelEventArgs^ e
)

public void OnSplitterMoving (
    SplitterCancelEventArgs e
)

JScript

public function OnSplitterMoving (
    e : SplitterCancelEventArgs
)

パラメータ

e: イベントデータを格納している SplitterEventArgs。

解説

SplitterMoving イベントは、分割線の移動中に発生します。SplitContainer の移動後にイベントを発生させるには、SplitterMoved イベントと OnSplitterMoved イベントハンドラを使用します。

イベントが発生すると、デリゲートを使用してイベントハンドラが呼び出されます。詳細については、「イベントの発生」を参照してください。

OnSplitterMoving メソッドを使用すると、デリゲートを結び付けずに、派生クラスでイベントを処理することもできます。派生クラスでイベントを処理する場合は、この手法をお勧めします。

継承時の注意 派生クラスで OnSplitterMoving をオーバーライドする場合は、登録されているデリゲートがイベントを受け取ることができるように、基本クラスの OnSplitterMoving メソッドを呼び出してください。

使用例

SplitterMoving イベントを発生させるコード例を次に示します。この例では、分割線を移動したときにカーソルスタイルが変更されることによって、このイベントの発生が通知されます。分割線の移動が中止されると、SplitterMoved イベントが発生します。この例では、カーソルスタイルが既定のスタイルに戻ることによって、このイベントの発生が通知されます。
