IProxyProviderWinEventHandler::RespondToWinEvent method

Handles a WinEvent.

Syntax

C++


HRESULT RespondToWinEvent(
  [in] DWORD                      idWinEvent,
  [in] HWND                       hwnd,
  [in] LONG                       idObject,
  [in] LONG                       idChild,
  [in] IProxyProviderWinEventSink *pSink
);

Parameters

idWinEvent [in]

Type: DWORD

The identifier of the incoming WinEvent. For a list of WinEvent IDs, see Event Constants.

hwnd [in]

Type: HWND

The handle of the window for which the WinEvent was fired. This should also be the window for which the proxy was created.

idObject [in]

Type: LONG

The object identifier (OBJID_*) of the accessible object associated with the event. For a list of object identifiers, see Object Identifiers.

idChild [in]

Type: LONG

The child identifier of the element associated with the event, or CHILDID_SELF if the element is not a child.

pSink [in]

Type: IProxyProviderWinEventSink*

A pointer to the IProxyProviderWinEventSink interface provided by the UI Automation core. Any event that the proxy needs to raise in response to the WinEvent being handled should be added to the sink.

Return value

Type: HRESULT

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

Remarks

The provider should review the event data. If the provider needs to raise a UI Automation event in response, the data for that event should be added to the pSink event sink.
