C++ (Cpp) RemoveEventListeners Examples

Example #1

STDMETHODIMP CSVGSwatchesDlg::handleDeactivateObjectEvent(IUnknown* object, long cookie, BOOL* bAllow)
{
	ASSERT(IsUnknownEqualUnknown(m_viewGroup, object));

//	IDispEventImpl<2, CSVGFiltersDlg, &DIID__IWebXMLDocumentEvents, &LIBID_WEBEDITORLib, 1, 0>::DispEventUnadvise(m_document);

	RemoveEventListeners();

	m_listView.RemoveItems();

	m_listView.m_xmlDocument.Release();

Example #2
