Another example is to retrieve information about the columns, such as the width or order. This can be done by using the GetItem method and passing in the column index and a pointer to a HDITEM structure, which receives the information. The following code snippet demonstrates how to retrieve the width of the first column in a list view control:C++ CHeaderCtrl* pHeaderCtrl = m_myListCtrl.GetHeaderCtrl(); HDITEM hdItem; hdItem.mask = HDI_WIDTH; pHeaderCtrl->GetItem(0, &hdItem); int nWidth = hdItem.cxy; ``` CHeaderCtrl is part of the MFC (Microsoft Foundation Classes) library, which is a package of C++ classes that provides functionality for creating Windows desktop applications.
