'Declaration Public Overridable Property Caption As String
'使用法 Dim instance As FpCheckBox Dim value As String instance.Caption = value value = instance.Caption
public virtual string Caption {get; set;}
このプロパティは、チェックボックスの各状態に異なるテキストを指定しない場合に使用します。各状態に異なるテキストを指定するには、TextIndeterminate、TextFalse、TextTrueの各プロパティを設定します。
各状態のテキストを設定すると、コントロールがその状態になったとき、設定したテキストによってCaptionプロパティの設定が上書きされます。たとえば、TextIndeterminateプロパティとTextFalseプロパティは設定せず、TextTrueプロパティのテキストのみを設定した場合、チェックボックスがTrueのときにTextTrueプロパティのテキストが表示されます。チェックボックスがFalseまたはIndeterminateのときはCaptionプロパティのテキストが表示されます。
