你好,我有两个问题:
cannot convert from 'std::vector<_Ty>' to 'std::vector<_Ty> &
void CMapObjectPropertyPageAmbience::OnUpdateUI(CProperty* pProperty) { prt::PropertyAmbienceStringToData(pProperty, &m_propertyAmbience); std::vector<CFilename>& rSoundFileNameVector = m_propertyAmbience.AmbienceSoundVector; for (DWORD dwIndex = 0; dwIndex < rSoundFileNameVector.size(); ++dwIndex) { m_ctrlSoundFileList.InsertString(dwIndex, rSoundFileNameVector[dwIndex].c_str()); } m_ctrlPlayType.SelectString(-1, m_propertyAmbience.strPlayType.c_str()); SetDialogFloatText(GetSafeHwnd(), IDC_MAP_OBJECT_PROPERTY_AMBIENCE_INTERVAL, m_propertyAmbience.fPlayInterval); SetDialogFloatText(GetSafeHwnd(), IDC_MAP_OBJECT_PROPERTY_AMBIENCE_INTERVAL_VARIATION, m_propertyAmbience.fPlayIntervalVariation); SetDialogFloatText(GetSafeHwnd(), IDC_MAP_OBJECT_PROPERTY_AMBIENCE_MAX_VOLUME_AREA_PERCENTAGE, m_propertyAmbience.fMaxVolumeAreaPercentage * 100.0f); OnUpdatePropertyData(m_propertyAmbience.strName.c_str()); OnChangePlayType(); }
错误出现在:
std::vector<CFilename>& rSoundFileNameVector = m_propertyAmbience.AmbienceSoundVector;
两个重载都不能转换所有参数类型:
void CMapObjectPropertyPageAmbience::OnDeleteSoundFile() { DWORD dwCurSel = DWORD(m_ctrlSoundFileList.GetCurSel()); if (dwCurSel >= m_propertyAmbience.AmbienceSoundVector.size()) return; DeleteVectorItem < CFilename > ( & m_propertyAmbience.AmbienceSoundVector, dwCurSel); m_ctrlSoundFileList.DeleteString(dwCurSel); }
在
DeleteVectorItem<CFilename>(&m_propertyAmbience.AmbienceSoundVector, dwCurSel);
全部错误

最佳答案
您正在尝试使用 vector<string>
在vector<CFilename>
的地方是期待。这些是完全不相关的类型。
关于c++ - 无法从 'std::vector<_Ty>' 转换为 'std::vector<_Ty> &,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/20927514/
