I've noticed a invalid behavior in the SetExtendedStyle method of CXTListCtrl (or more exactly of CXTListCtrlBase).

The code is currently:

AFX_INLINE void CXTListCtrlBase::SetExtendedStyle(DWORD dwExStyle) {

ASSERT(::IsWindow(m_pListCtrl->GetSafeHwnd())); m_pListCtrl->SendMessage(LVM_SETEXTENDEDLISTVIEWSTYLE, 0, GetExtendedStyle()|dwExStyle);

}

The use of GetExtendedStyle() prevent the switching on/off of a style. For example:

if ( g_nOptions & MAINOPTIONS_USEGRIDLINES )

m_List.SetExtendedStyle(m_List.GetExtendedStyle()|LVS_EX_GRI DLINES);

else

m_List.SetExtendedStyle(m_List.GetExtendedStyle()&~LVS_E X_GRIDLINES);

does not work with CXTListCtrl, while is works with CListCtrl.

Is there a reason for XT to use "GetExtendedStyle()|dwExStyle" instead of just "dwExStyle" ?

 

Thanks
