示例1: CalcMinColumnWidth
int CFileBrowserListCtrl::CalcMinColumnWidth(int Col)
{
enum {
BORDER = 6, // minimal spacing; less causes abbreviated text
SLACK = 3 // prevents widest item from touching right edge
};
CWaitCursor wc; // iterating all items can be slow, especially for file type
CClientDC dc(this);
HGDIOBJ PrevFont = dc.SelectObject(GetFont()); // must use list control's font
int width = 0;
CSize sz;
CFileInfo FileInfo;
CString str;
int items = m_DirList.GetCount();
