如何在LISTCTRL的列表头添加三态复选框

Answer 1

BOOL CSaomiaojieguo::OnInitDialog()
{
CDialog::OnInitDialog();
m_list1ctrl.SetExtendedStyle(LVS_EX_GRIDLINES | LVS_EX_CHECKBOXES|LVS_EX_FULLROWSELECT|LVS_EDITLABELS);
CRect rect4;
m_list1ctrl.GetClientRect(rect4);
this->m_list1ctrl.SetExtendedStyle(m_list1ctrl.GetExtendedStyle() | LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES | LVS_EX_HEADERDRAGDROP | LVS_EX_TWOCLICKACTIVATE);
this->m_list1ctrl.InsertColumn(0, _TEXT("文件名"), LVCFMT_LEFT, 230);
this->m_list1ctrl.InsertColumn(1, _TEXT("文件大小(字节)"), LVCFMT_LEFT, 115);
this->m_list1ctrl.InsertColumn(2, _TEXT("创建日期"), LVCFMT_LEFT, 150);
this->m_list1ctrl.InsertColumn(3, _TEXT("绝对路径"), LVCFMT_LEFT, 1000);
// TODO: Add extra initialization here
//Recurse(str);
return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}
会看这个吗？这个是listctrl所在窗口的初始化函数，其中
m_list1ctrl.SetExtendedStyle(LVS_EX_GRIDLINES | LVS_EX_CHECKBOXES|LVS_EX_FULLROWSELECT|LVS_EDITLABELS);
就是你先要加的复选框
