Mouse.OverrideCursor 屬性

定義

命名空間:

System.Windows.Input

組件:

PresentationCore.dll

取得或設定整個應用程式的游標。

public:
 static property System::Windows::Input::Cursor ^ OverrideCursor { System::Windows::Input::Cursor ^ get(); void set(System::Windows::Input::Cursor ^ value); };

public static System.Windows.Input.Cursor OverrideCursor { get; set; }

static member OverrideCursor : System.Windows.Input.Cursor with get, set

Public Shared Property OverrideCursor As Cursor

屬性值

Cursor

覆寫游標，如果未設定 null，則為 OverrideCursor。

範例

下列範例顯示 的 RadioButton 事件處理程式，用來切換單一專案與整個應用程式之間的數據指標變更範圍。 如果引發事件的控制項是 rbScopeElementRadioButton，表示資料指標變更範圍的旗標已設定，且 OverrideCursor 設定為 null。 如果引發事件的控件是 rbScopeApplicationRadioButton，表示數據指標變更範圍的旗標已設定，並且OverrideCursor設定為Cursor名為 DisplayArea之控件的 Border 屬性。

// Determines the scope the new cursor will have.
//
// If the RadioButton rbScopeElement is selected, then the cursor
// will only change on the display element.
// 
// If the Radiobutton rbScopeApplication is selected, then the cursor
// will be changed for the entire application
//
private void CursorScopeSelected(object sender, RoutedEventArgs e)
{
    RadioButton source = e.Source as RadioButton;

    if (source != null)
    {
        if (source.Name == "rbScopeElement")
        {
            // Setting the element only scope flag to true
            cursorScopeElementOnly = true;

            // Clearing out the OverrideCursor.  
            Mouse.OverrideCursor = null;
        }
        if (source.Name == "rbScopeApplication")
        {
           // Setting the element only scope flag to false
           cursorScopeElementOnly = false;

           // Forcing the cursor for all elements. 
           Mouse.OverrideCursor = DisplayArea.Cursor;
        }
    }
}

        cursorScopeElementOnly = True
        ' Clearing out the OverrideCursor.
        Mouse.OverrideCursor = Nothing

    End If
    If (source.Name = "rbScopeApplication") Then
        ' Setting the element only scope flag to false.
        cursorScopeElementOnly = False

    End If
End Sub

備註

OverrideCursor設定為的 Cursor 將會套用到整個應用程式的 。

若要清除覆寫 Cursor，請將 設定 OverrideCursor 為 null。

將 設定 OverrideCursor 為 None 會強制不顯示滑鼠游標，但仍會處理滑鼠事件。
