示例

以下示例演示 的 事件处理程序 RadioButton ，用于在单个元素和整个应用程序之间切换游标更改的范围。 如果引发 事件的控件是 rbScopeElementRadioButton，则会设置一个表示游标更改范围的标志，并将其 OverrideCursor 设置为 null。 如果引发事件的控件是 rbScopeApplicationRadioButton，则设置一个表示游标更改范围的标志，并将其OverrideCursor设置为Cursor名为 DisplayArea的 控件的 Border 属性。

// 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;
        }
    }
}

注解

Cursor设置为 的 OverrideCursor 将应用于整个应用程序。

若要清除替代 Cursor，请将 设置为 OverrideCursornull。

将 设置为 OverrideCursorNone 将强制不显示鼠标光标，但仍会处理鼠标事件。
