TreeView.Scrollable 속성

  • 아티클

tree view 컨트롤에서 필요할 때 스크롤 막대를 표시할지 여부를 나타내는 값을 가져오거나 설정합니다.

네임스페이스: System.Windows.Forms
어셈블리: System.Windows.Forms(system.windows.forms.dll)

구문

‘선언
Public Property Scrollable As Boolean
‘사용 방법
Dim instance As TreeView
Dim value As Boolean

value = instance.Scrollable

instance.Scrollable = value

public bool Scrollable { get; set; }

public:
property bool Scrollable {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_Scrollable ()

/** @property */
public void set_Scrollable (boolean value)

public function get Scrollable () : boolean

public function set Scrollable (value : boolean)

속성 값

tree view 컨트롤에서 필요할 때 스크롤 막대를 표시하면 true이고, 그렇지 않으면 false입니다. 기본값은 true입니다.

설명

이 속성이 true로 설정되면 TreeNode가 컨트롤의 클라이언트 영역 밖에 있을 때 스크롤 막대가 TreeView에 표시됩니다.

참고

런타임에 Scrollable 속성을 설정하면 컨트롤의 모양을 업데이트하도록 TreeView 핸들이 다시 만들어집니다(Control.RecreateHandle 참조). 이 경우 선택된 TreeNode를 제외하고 모든 트리 노드가 축소됩니다.

예제

다음 코드 예제에서는 BorderStyle 열거형과 BorderStyle, ShowLines, Scrollable, HideSelection 및 ShowRootLines 속성을 사용하는 방법을 보여 줍니다. 이 예제를 실행하려면 폼에 다음 코드를 붙여넣고 폼의 생성자나 Load 메서드에서 InitializeTreeView 메서드를 호출합니다.
