TreeNode.ForeColor プロパティ

定義

ツリー ノードの前景色を取得または設定します。

public:
 property System::Drawing::Color ForeColor { System::Drawing::Color get(); void set(System::Drawing::Color value); };
public System.Drawing.Color ForeColor { get; set; }
member this.ForeColor : System.Drawing.Color with get, set
Public Property ForeColor As Color

プロパティ値

Color

ツリー ノードの前景色を示す Color

次のコード例では、子ツリー ノードを割り当てるルート ツリー ノードを作成します。 ルート ツリー ノードと、オブジェクトにArrayList割り当てられている各Customerオブジェクトの子ツリー ノードには、オブジェクトの各Orderオブジェクトの子ツリー ノードがCustomer追加されます。 オブジェクトが Customer プロパティに Tag 割り当てられ、オブジェクトを表す Customer ツリー ノードがテキストで Orange 表示されます。 この例では、定義されたCustomerオブジェクトOrder、コントロール、FormオブジェクトArrayListTreeView含むCustomer名前付きcustomerArrayコントロールが必要です。

   Order( String^ myOrderID )
   {
      this->OrderID = myOrderID;
   }

の場合 nullは、 Color ツリー ノードが ForeColor 割り当てられているコントロールの TreeView プロパティ値が使用されます。
