自定义MFC ClistCtrl控件的示例代码
Author: kagula@20150401
环境: vs2013sp1
自定义行高、字体、颜色。
如何引用的示例代码
初始化
BOOL CTestListCtrlDlg::OnInitDialog()
{
CDialogEx::OnInitDialog();
// 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
{
DWORD dwStyle = m_list.GetExtendedStyle(); //添加列表框的网格线！！！
dwStyle |= LVS_EX_FULLROWSELECT;
dwStyle |= LVS_EX_GRIDLINES;
m_list.SetExtendedStyle(dwStyle);
m_list.InsertColumn(0,L"编号",LVCFMT_LEFT,32); //添加列标题！！！！ 这里的80,40,90用以设置列的宽度。！！！LVCFMT_LEFT用来设置对齐方式！！！
m_list.InsertColumn(1,L"商品名称",LVCFMT_LEFT,256);
m_list.InsertColumn(2,L"颜色",LVCFMT_CENTER,32);
m_list.InsertColumn(3,L"尺码",LVCFMT_CENTER,32);
m_list.InsertColumn(4,L"数量",LVCFMT_CENTER,32);
InitList();
}
//m_list.SetFontSelf(15,L"黑体");//设定表体中的字体
int nRow = m_list.InsertItem(0,L"");
m_list.SetItemText(nRow,0,L"编号");
m_list.SetItemText(nRow,1,L"商品名称");
m_list.SetItemText(nRow,2,L"颜色");
m_list.SetItemText(nRow,3,L"尺码");
m_list.SetItemText(nRow,4,L"数量");
nRow = m_list.InsertItem(1,L"");
m_list.SetItemText(nRow,0,L"编号2");
m_list.SetItemText(nRow,1,L"商品名称2");
m_list.SetItemText(nRow,2,L"颜色2");
m_list.SetItemText(nRow,3,L"尺码2");
m_list.SetItemText(nRow,4,L"数量2");
return TRUE; // return TRUE unless you set the focus to a control
}
void CRFI_CHECK_DLG::InitList()
{
static bool bFirst = true;
if (bFirst)
{
bFirst=FALSE;
CHeaderCtrl *pHeader = NULL;
pHeader = m_list.GetHeaderCtrl();
if(pHeader)
{
TRACE("header item count:%d/n", pHeader->GetItemCount());
int iColumn=pHeader->GetItemCount();
for (int i=0; i<iColumn; i++)
{
HDITEM hdItem;
BOOL bResult = FALSE;
bResult=pHeader->GetItem(i, &hdItem); //直接在OnInitDialog中调用，程序会挂掉。
hdItem.fmt |= HDF_OWNERDRAW;
bResult=pHeader->SetItem(i, &hdItem);
}
//pHeader->Invalidate();
}
}
}
缩放
void CTestListCtrlDlg::OnSize(UINT nType, int cx, int cy)
{
CDialogEx::OnSize(nType, cx, cy);
CRect rectClient;
GetClientRect(&rectClient);
{
int left = 0;
int top = 39;
int columnWidth = 52;
int widthProductName = (rectClient.Width()-columnWidth*4)<128?128:(rectClient.Width()-columnWidth*4);
CRect rect(left,top,left+rectClient.Width(),rectClient.Height()-64);
GetDlgItem(IDC_LIST2)->MoveWindow(&rect);
m_list.SetColumnWidth(0,columnWidth);
m_list.SetColumnWidth(1,widthProductName);
m_list.SetColumnWidth(2,columnWidth);
m_list.SetColumnWidth(3,columnWidth);
m_list.SetColumnWidth(4,columnWidth);
}
}
