UI Automation-ExpandCollapsePattern

来源：互联网发布：notepad 排版json 编辑：程序博客网时间：2024/05/23 16:55

ExpandCollapsePattern是可以进行展开（以显示内容）和折叠（以隐藏内容）的控件。例如ComboBox控件支持ExpandCollapsePattern。

ExpandCollapsePattern有两个主要方法：

Expand（）方法和Collapse（）方法。可以把Expand和Collpase再封装。示例如下：

public static void launchCal()

{

//Launch Calculator

Process proc = Process.Start("calc");

Thread.Sleep(2000);

//Recognize Calculator Window "Calculator"

AutomationElement window = AutomationElement.RootElement.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Calculator"));

//Assert.IsNotNull(window);

Thread.Sleep(2000);

//Expand view button

//Recognize view menu

AutomationElement view = window.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "View"));

Assert.IsNotNull(view);

Thread.Sleep(2000);

Utility.UIA.ControlPattern.ExpandCollapsepattern.Expand(view);

Thread.Sleep(2000);

//Recognize menu item Worksheets

AutomationElement worksheets = window.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "Worksheets"));

Assert.IsNotNull(worksheets);

Utility.UIA.ControlPattern.ExpandCollapsepattern.ExpandCollapseMenuItem(worksheets);

Thread.Sleep(2000);

}

public static void Expand(AutomationElement targetControl)

{

ExpandCollapsePattern expandCollapsePattern = null;

try

{

expandCollapsePattern =

targetControl.GetCurrentPattern(

ExpandCollapsePattern.Pattern)

as ExpandCollapsePattern;

}

// Object doesn't support the ExpandCollapsePattern control pattern.

catch (InvalidOperationException)

{

throw new InvalidOperationException(string.Format("Element with AutomationId '{0}' and Name '{1}' does not support the ExpandCollapsePattern control pattern ",

targetControl.Current.AutomationId, targetControl.Current.Name));

}

expandCollapsePattern.Expand();

}

public static void Collapse(AutomationElement targetControl)

{

ExpandCollapsePattern expandCollapsePattern = null;

try

{

expandCollapsePattern =

targetControl.GetCurrentPattern(

ExpandCollapsePattern.Pattern)

as ExpandCollapsePattern;

}

// Object doesn't support the ExpandCollapsePattern control pattern.

catch (InvalidOperationException)

{

throw new InvalidOperationException(string.Format("Element with AutomationId '{0}' and Name '{1}' does not support the ExpandCollapsePattern control pattern ",

targetControl.Current.AutomationId, targetControl.Current.Name));

}

expandCollapsePattern.Collapse();

}

public static ExpandCollapsePattern GetExpandCollapsePattern(

AutomationElement targetControl)

{

ExpandCollapsePattern expandCollapsePattern = null;

try

{

expandCollapsePattern =

targetControl.GetCurrentPattern(

ExpandCollapsePattern.Pattern)

as ExpandCollapsePattern;

}

// Object doesn't support the ExpandCollapsePattern control pattern.

catch (InvalidOperationException)

{

return null;

}

return expandCollapsePattern;

}
