IUIAutomationTreeWalker::GetPreviousSiblingElement method (uiautomationclient.h)

Retrieves the previous sibling element of the specified UI Automation element.

Syntax

HRESULT GetPreviousSiblingElement(
  [in]          IUIAutomationElement *element,
  [out, retval] IUIAutomationElement **previous
);

Parameters

[in] element

Type: IUIAutomationElement*

A pointer to the element for which to retrieve the previous sibling.

[out, retval] previous

Type: IUIAutomationElement**

Receives a pointer to the previous sibling element, or NULL if there is no sibling element.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

An element can have additional sibling elements that do not match the current view condition and thus are not returned when navigating the element tree.

The structure of the Microsoft UI Automation tree changes as the visible UI elements on the desktop change. It is not guaranteed that an element returned as the previous sibling element will be returned as the previous sibling on subsequent passes.
