MultipleViewPattern控件模式用于支持控件,控件提供了同一组信息或子控件的多个表示形式,并且可以在这些表示形式之间进行切换。常用两种方法,GetViewName用来检索特定于控件的视图的名称,还有SetCurrentView,用来设置当前的特定于控件的视图。
示例:
public static void TestMultipleViewpattern()
{
Process adressbook = Process.Start(@"C:/Program Files/Outlook Express/wab.exe");
Thread.Sleep(2000);
//Get main window "Address Book - Main Identity"
AutomationElement addresswindow = AutomationElement.RootElement.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Address Book - Main Identity"));
Thread.Sleep(2000);
AutomationElement list = Utility.UIA.FindAutomationElement.ByAutomationID(addresswindow, "9001",true);
MultipleViewPattern listpattern = Utility.UIA.ControlPattern.MultipleViewpattern.GetMultipleViewPattern(list);
if (listpattern.Current.CurrentView != 3)
{
//get view menu item
AutomationElement view = Utility.UIA.FindAutomationElement.ByName(addresswindow, "View", false);
ExpandCollapsePattern viewpattern = Utility.UIA.ControlPattern.ExpandCollapsepattern.GetExpandCollapsePattern(view);
viewpattern.Expand();
Thread.Sleep(2000);
//get list menu item
AutomationElement listitem = Utility.UIA.FindAutomationElement.ByName(addresswindow, "List", false);
InvokePattern listpattern1 = Utility.UIA.ControlPattern.Invokepattern.GetInvokePattern(listitem);
listpattern1.Invoke();
}
}
public static MultipleViewPattern GetMultipleViewPattern(AutomationElement element)
{
object currentPattern;
if (!element.TryGetCurrentPattern(MultipleViewPattern.Pattern, out currentPattern))
{
throw new Exception(string.Format("Element with AutomationId '{0}' and Name '{1}' does not support the DockPattern.",
element.Current.AutomationId, element.Current.Name));
}
return currentPattern as MultipleViewPattern;
}
