ValuePattern.IsReadOnlyProperty 필드

정의

IsReadOnly 속성을 식별합니다.Identifies the IsReadOnly property.

public: static initonly System::Windows::Automation::AutomationProperty ^ IsReadOnlyProperty;
public static readonly System.Windows.Automation.AutomationProperty IsReadOnlyProperty;
 staticval mutable IsReadOnlyProperty : System.Windows.Automation.AutomationProperty
Public Shared ReadOnly IsReadOnlyProperty As AutomationProperty 

필드 값

예제

다음 예제에서는 루트 요소를 루트의 후손이 속성 조건 집합을 만족 하는 UI 자동화 요소의 컬렉션을 반환 하는 함수에 전달 됩니다.In the following example, a root element is passed to a function that returns a collection of UI automation elements that are descendants of the root and satisfy a set of property conditions.

///--------------------------------------------------------------------
/// <summary>
/// Finds all automation elements that satisfy 
/// the specified condition(s).
/// </summary>
/// <param name="targetApp">
/// The automation element from which to start searching.
/// </param>
/// <returns>
/// A collection of automation elements satisfying 
/// the specified condition(s).
/// </returns>
///--------------------------------------------------------------------
private AutomationElementCollection FindAutomationElement(
    AutomationElement targetApp)
{
    if (targetApp == null)
    {
        throw new ArgumentException("Root element cannot be null.");
    }

    PropertyCondition conditionIsReadOnly =
        new PropertyCondition(
        ValuePattern.IsReadOnlyProperty, false);

    return targetApp.FindAll(
        TreeScope.Descendants, conditionIsReadOnly);
}

설명

이 식별자는 UI 자동화 클라이언트 애플리케이션에서 사용 됩니다.This identifier is used by UI Automation client applications. UI 자동화 공급자의 해당 필드를 사용 해야 ValuePatternIdentifiers합니다.UI Automation providers should use the equivalent field in ValuePatternIdentifiers.

컨트롤 있어야 해당 IsEnabledProperty 로 설정 true 및 해당 IsReadOnlyProperty 로 설정 false 클라이언트에 대 한 호출을 시도 하기 전에 SetValue입니다.A control should have its IsEnabledProperty set to true and its IsReadOnlyProperty set to false before a client attempts a call to SetValue.
