示例1:
bool
wxIDataObject::HasSystemData(wxDataFormat format) const
{
for ( SystemData::const_iterator it = m_systemData.begin();
it != m_systemData.end();
++it )
{
FORMATETC* formatEtc = (*it)->pformatetc;
if ( formatEtc->cfFormat == format )
return true;
}
return false;
}示例2: wxCopyStgMedium
bool
wxIDataObject::GetSystemData(wxDataFormat format, STGMEDIUM *pmedium) const
{
for ( SystemData::const_iterator it = m_systemData.begin();
it != m_systemData.end();
++it )
{
FORMATETC* formatEtc = (*it)->pformatetc;
if ( formatEtc->cfFormat == format )
{
wxCopyStgMedium((*it)->pmedium, pmedium);
return true;
}
}
return false;
}示例3: delete
// save system data
HRESULT
wxIDataObject::SaveSystemData(FORMATETC *pformatetc,

BOOL fRelease)
{
if ( pformatetc == NULL || pmedium == NULL )

}
// create new format/medium
