如何在ListCtrlEx（Not ListCtrl）项目中绘制图像？ [英] How to draw images inside ListCtrlEx (Not ListCtrl) items?
问题描述
最近我使用的是ListCtrlEx （不是ListCtrl）。我从
获得示例演示 某些网站（此处不允许发布链接）。为了在列表框中的项目中绘制图像，我在ListCtrlExDemoDlg.cpp的OnInitialDialog中进行了一些更改，
添加了一些用InsertPic和AddImages命名的函数。但我看不到列表框中的任何图片，谁可以帮助我呢？我的编译环境是vs 2010. 或者
可以给我一些完整的演示？谢谢。

Recently I am using ListCtrlEx (NOT ListCtrl). And I got the example demo from
some website (It is not allowed to publish link here). To draw images in the item in the List Box I made some change in OnInitialDialog of ListCtrlExDemoDlg.cpp, add some function named with InsertPic and AddImages. But I can not see any pictures in the List Box, who can help me with it? My compile environment is vs 2010. or who can give me some complete demo? Thank you.
Global variable:
ListCtrlEx::CListCtrlEx m_list;
CImageList m_imList;
BOOL CListCtrlExDemoDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// Add "About..." menu item to system menu.
// IDM_ABOUTBOX must be in the system command range.
ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
ASSERT(IDM_ABOUTBOX < 0xF000);
CMenu* pSysMenu = GetSystemMenu(FALSE);
if (pSysMenu != NULL)
{
CString strAboutMenu;
strAboutMenu.LoadString(IDS_ABOUTBOX);
if (!strAboutMenu.IsEmpty())
{
pSysMenu->AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
}
}
// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon
m_list.ModifyStyle(0, LVS_SINGLESEL|LVS_REPORT|LVS_SHOWSELALWAYS);
m_list.SetExtendedStyle(m_list.GetExtendedStyle() |LVS_EX_FULLROWSELECT );
InsertPicAndWord();
return TRUE; // return TRUE unless you set the focus to a control
