The x axis (100) is variable and can be changed\r\n\tto almost any number without bad side effects. The y axis (48) can be changed\r\n\tbut you will need to adjust the m_nItemSpacing in the InitDialog\r\n\tSet m_ItemSpacing to Bitmap Height + 20. This will allow enough\r\n\tclearance for the rectangle that is drawn when an item is selected (Assuming you\r\n\tare using the Arial 8 pt. font). m_nOffsetY determines the amount of space to leave\r\n\tblank at the top of each list item. The actual listbox control is in a class called\r\n\tCPicListBox which is an owner draw listbox derived from CListBox. This is called in the\r\n\tconstructor of CPicListBoxWnd. A Listbox sends messages to its parent window only. This is\r\n\tthe reason for CPicListBoxWnd's existance.\r\n\r\n\tCode By: Todd Osborne\t12/14/93\r\n*/\r\n\r\n#include <afxwin.h>\r\n#include <afxext.h>\r\n#include \"piclistb.h\"\r\n\r\n#ifdef _DEBUG\r\n#undef THIS_FILE\r\nstatic char BASED_CODE THIS_FILE[] = __FILE__;\r\n#endif\r\n\r\n/////////////////////////////////////////////////////////////////////////////\r\n// CPicListBoxWnd\r\nCPicListBoxWnd::CPicListBoxWnd(CWnd* pParent)\r\n{\r\n\tCRect Prect;\r\n\tpParent->GetClientRect(&Prect);\r\n\t\r\n\tCRect rect(0, 0, 150, Prect.Height());\r\n\tCreate(NULL, \"\", WS_CHILD | WS_VISIBLE, rect, pParent, 5000, NULL);\r\n\t\r\n\t// Set Variables needed for drawing list box (See Notes above and in .h file)\r\n\tm_nListCount = 0;\r\n\tm_nOffsetY = 13;\r\n\tm_nItemSpacing = 78;\r\n\t\r\n\t// Create the actual List Box\r\n\tm_pLB_LIST= new CPicListBox(this);\r\n\t\r\n\t// Add Item(s) to List Box\r\n\tAddItem(\"A\", \"Test 0\");\r\n\tAddItem(\"B\", \"Test 1\");\r\n\tAddItem(\"C\", \"Test 2\");\r\n\tAddItem(\"D\", \"Test 3\");\r\n\tAddItem(\"E\", \"Test 4\");\r\n}\r\n\r\nCPicListBoxWnd::~CPicListBoxWnd()\r\n{\r\n\tdelete m_pLB_LIST;\r\n}\r\n\r\nvoid CPicListBoxWnd::AddItem(CString szBitmapName, CString szCaption)\r\n{\r\n\t// szBitampName: \t\tString name of bitmap in resource file\r\n\t// szCaption:\t\t\tString to be displayed to right of bitmap in list\r\n\tif ( m_nListCount<=24 )\r\n\t\t{\r\n\t\tm_ListItem.m_Bitmap[m_nListCount].LoadBitmap(szBitmapName);\r\n\t\tm_ListItem.m_Caption[m_nListCount] = szCaption;\r\n\t\tm_pLB_LIST->AddString((LPCSTR)&m_ListItem.m_Bitmap[this->m_nListCount]);\r\n\t\tthis->m_nListCount++;\r\n\t\t}\r\n}\r\n\r\nBEGIN_MESSAGE_MAP(CPicListBoxWnd, CWnd)\r\n\t//{{AFX_MSG_MAP(CPicListBoxWnd)\r\n\tON_WM_CREATE()\r\n\tON_WM_DRAWITEM()\r\n\tON_WM_MEASUREITEM()\r\n\tON_LBN_DBLCLK(5001, OnDblclkList)\r\n\t//}}AFX_MSG_MAP\r\nEND_MESSAGE_MAP()\r\n\r\n/////////////////////////////////////////////////////////////////////////////\r\n// CPicListBoxWnd message handlers\r\nint CPicListBoxWnd::OnCreate(LPCREATESTRUCT lpCreateStruct)\r\n{\r\n\tif (CWnd::OnCreate(lpCreateStruct) == -1)\r\n\t\treturn -1;\r\n\t\r\n\t// Font to be used in List Box\r\n\tm_ListFont = CreateFont(14, 0, 0, 0, FW_MEDIUM, 0, 0, 0, ANSI_CHARSET, OUT_STROKE_PRECIS,\tCLIP_STROKE_PRECIS,\tDEFAULT_QUALITY, FF_SWISS | FF_DONTCARE, \"Arial\" );\r\n\t\r\n\treturn 0;\r\n}\r\n\r\nvoid CPicListBoxWnd::OnDrawItem(int nIDCtl, LPDRAWITEMSTRUCT lpDrawItemStruct)\r\n{\r\n\tCDC* pDC = CDC::FromHandle(lpDrawItemStruct->hDC);\r\n\t\t\r\n\tif ((lpDrawItemStruct->itemState & ODS_SELECTED) && (lpDrawItemStruct->itemAction & (ODA_SELECT | ODA_DRAWENTIRE)))\r\n\t{\r\n\t\t// item has been selected -
