ColorDialog.SolidColorOnly プロパティ
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)

Dim instance As ColorDialog Dim value As Boolean value = instance.SolidColorOnly instance.SolidColorOnly = value
/** @property */ public boolean get_SolidColorOnly () /** @property */ public void set_SolidColorOnly (boolean value)
public function get SolidColorOnly () : boolean public function set SolidColorOnly (value : boolean)
ユーザーが純色のみ選択できる場合は true。それ以外の場合は false。既定値は false です。


AnyColor プロパティと AllowFullOpen プロパティを設定して ColorDialog を初期化する方法を次のコード例に示します。ColorDialog ではユーザーがカスタム カラーを設定することはできません。ただし、基本色セットはすべて表示できます。SolidColorOnly プロパティを false に設定すると、256 色以下のシステム上の色を組み合わせた色を表示できるようになります。またこの例では、ShowHelp プロパティの設定方法と、ダイアログの HelpRequest イベントの処理方法も示します。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て、フォームのコンストラクタまたは Load メソッドで InitializeColorDialog メソッドを呼び出します。この例では、ボタンの Click イベントが、この例で定義されているイベント処理メソッドに関連付けられている必要があります。
