IUIAutomationTreeWalker::GetFirstChildElement method

Retrieves the first child element of the specified UI Automation element.

Syntax


HRESULT GetFirstChildElement(
  [in]           IUIAutomationElement *element,
  [out, retval]  IUIAutomationElement **first
);

Parameters

element [in]

Type: IUIAutomationElement*

first [out, retval]

Type: IUIAutomationElement**

Receives a pointer to the first child 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 child 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 first child element will be returned as the first child on subsequent passes.
