StatusBarPanel.Style プロパティ

ステータスバーパネルのスタイルを取得または設定します。

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 Property Style As
 StatusBarPanelStyle

Visual Basic (使用法)

Dim instance As StatusBarPanel
Dim value As StatusBarPanelStyle

value = instance.Style

instance.Style = value

public StatusBarPanelStyle Style { get; set;
 }

C++

public:
property StatusBarPanelStyle Style {
    StatusBarPanelStyle get ();
    void set (StatusBarPanelStyle value);
}

/** @property */
public StatusBarPanelStyle get_Style ()

/** @property */
public void set_Style (StatusBarPanelStyle
 value)

JScript

public function get Style
 () : StatusBarPanelStyle

public function set Style
 (value : StatusBarPanelStyle)

プロパティ値
StatusBarPanelStyle 値の 1 つ。既定値は Text です。

例外

例外の種類	条件
InvalidEnumArgumentException	プロパティに代入された値が StatusBarPanelStyle 列挙体のメンバではありません。

解説

このプロパティを使用すると、StatusBarPanel にテキストが表示されるかどうか、またはパネルをオーナー描画 StatusBarPanel として管理するかどうかを示すことができます。いつ StatusBarPanel を描画する必要があるかを確認するには、StatusBar コントロールの DrawItem イベントのイベントハンドラを作成します。DrawItem イベントのイベントハンドラにパラメータとして渡された StatusBarDrawItemEventArgs を使用すると、どのパネルを描画する必要があるかを確認できます。StatusBarDrawItemEventArgs は、StatusBarPanel 上で描画タスクを実行するために使用する Graphics オブジェクトも提供します。

使用例

Style プロパティ、StatusBarDrawItemEventHandler デリゲート、StatusBarDrawItemEventArgs クラス、StatusBarPanelStyle 列挙体、および StatusBarDrawItemEventArgs.Panel プロパティの使用方法を次のコード例に示します。この例を実行するには、次のコードをフォームに貼り付けます。そして、フォームのコンストラクタまたは Load のイベント処理メソッドで InitializeStatusBarPanels メソッドを呼び出します。

StatusBarPanel メンバ

StatusBarPanelStyle

StatusBarPanelStyle 列挙体

StatusBar コントロール上の StatusBarPanel オブジェクトが、オーナー描画またはシステム描画のどちらであるかを指定します。

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 Enumeration StatusBarPanelStyle

Visual Basic (使用法)

Dim instance As StatusBarPanelStyle

public enum StatusBarPanelStyle

C++

public enum class StatusBarPanelStyle

public enum StatusBarPanelStyle

JScript

public enum StatusBarPanelStyle

メンバ

	メンバ名	説明
	OwnerDraw	StatusBarPanel はオーナーによって描画されます。
	Text	StatusBarPanel は、標準フォントでテキストを表示します。

解説

この列挙体のメンバを使用して、StatusBarPanel クラスの Style プロパティの値を設定します。Style プロパティは、StatusBarPanel の表示方法を決定します。StatusBarPanel オブジェクトは、単純なテキストを表示できたり、オーナー描画であったりします。オーナー描画 StatusBarPanel オブジェクトは、イメージや StatusBar コントロール上の残りの StatusBarPanel オブジェクトとは異なるフォントの表示をサポートします。一方、システム描画 StatusBarPanel オブジェクトは、テキストだけ (StatusBarPanel の Icon プロパティでアイコンが指定されている場合は、テキストおよびアイコン) を表示するために使用します。オーナー描画 StatusBarPanel 上でオーナー描画操作を実行するには、StatusBar コントロールの DrawItem イベントを使用します。

使用例

Style プロパティ、StatusBarDrawItemEventHandler デリゲート、StatusBarDrawItemEventArgs クラス、StatusBarPanelStyle 列挙体、および StatusBarDrawItemEventArgs.Panel プロパティの使用方法を次のコード例に示します。この例を実行するには、次のコードをフォームに貼り付けます。そして、フォームのコンストラクタまたは Load イベント処理メソッドで InitializeStatusBarPanels メソッドを呼び出します。
