Answer 1

重载CListCtrl::DrawItem.  选上LVS_OWNERDRAWFIXED属性
void CListCtrlEx::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
    //得到dc
    LPDRAWITEMSTRUCT lpDIS = lpDrawItemStruct;
    CDC* pDC = CDC::FromHandle(lpDIS->hDC);    LVITEM lvi = {0};
    lvi.mask = LVIF_STATE;//|LVIF_IMAGE;
    lvi.stateMask = LVIS_FOCUSED | LVIS_SELECTED ;
    lvi.iItem = lpDIS->itemID;
    BOOL bGet = GetItem(&lvi);    BOOL bHighlight =((lvi.state & LVIS_DROPHILITED)||((lvi.state & LVIS_SELECTED) && 
            ((GetFocus() == this)|| (GetStyle() & LVS_SHOWSELALWAYS))));    // 画文本背景
    CRect rcBack = lpDIS->rcItem;
    pDC->SetBkMode(TRANSPARENT);
    if( bHighlight )
    {
        pDC->SetTextColor(::GetSysColor(COLOR_HIGHLIGHTTEXT));
        pDC->SetBkColor(::GetSysColor(COLOR_HIGHLIGHT));        pDC->FillRect(rcBack, &CBrush(::GetSysColor(COLOR_HIGHLIGHT)));
    }
    else
    {
        if (lpDIS->itemID%2 ==0)
        {
            pDC->SetTextColor(0x0C0F80);
            pDC->FillRect(rcBack, &CBrush(0xEEF1E3));
        }
        else
        {
            pDC->SetTextColor(RGB(0,128,255));
            pDC->FillRect(rcBack, &CBrush(0xE3e3e3));
        }
    }    //设置字体颜色
    CString str;    //得到焦点大小
    CRect rcFocus = lpDIS->rcItem;
    rcFocus.DeflateRect(1,1,1,1);    if (lpDIS->itemAction & ODA_DRAWENTIRE)
    {
        //写文本
        CString szText;
        for (int i = 0; i < GetColumns(); i++)
        { //循环得到文本
            CRect rcItem;
            if ( !GetSubItemRect(lpDIS->itemID, i, LVIR_LABEL, rcItem ))
            continue;
            szText = GetItemText( lpDIS->itemID, i );            rcItem.left += 5; rcItem.right -= 1;
            pDC->DrawText(szText, lstrlen(szText), &rcItem, DT_CENTER|DT_VCENTER|DT_NOPREFIX|DT_SINGLELINE);
        }
    }
}

我的应用实例是,一个listctrl,用鼠标在上边点中一行,那一行就要被删除,比如点了5行,那5行就要变得disable的状态(变灰了).所以...请继续帮忙

你必须设定 list控件的More styles 为 Owner draw fixed.
或者调用 SetExtendedStyle(GetExtentedStyle()|******* )具体参数不记得了。

Answer 5

TN014: Custom Controls:
For self-drawing list boxes and combo boxes, you must override MeasureItem and DrawItem. You must specify the OWNERDRAWVARIABLE style in the dialog template (LBS_OWNERDRAWVARIABLE and CBS_OWNERDRAWVARIABLE respectively). The OWNERDRAWFIXED style will not work with self-drawing items since the fixed item height is determined before self-drawing controls are attached to the list box. (The Win 3.1 member functions CListBox::SetItemHeight and CComboBox::SetItemHeight can be used to get around this limitation.)

pListCtrl->SetFocus();
pListCtrl->SetItemState(idx, LVIS_SELECTED, LVIS_SELECTED);
