rt,还有就是如何设置选中的行？
VC6.0中的CListCtrl控件，当你选择某一栏时并不能全行加亮显示，下面将告诉你怎样来实现全行加亮显示
派生一个新类，其基类为CListCtrl，并手工加入DrawItem函数。
void BListCtrl::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
CDC *pDC=CDC::FromHandle(lpDrawItemStruct->hDC);
CRect rcItem(lpDrawItemStruct->rcItem);
int nItem=lpDrawItemStruct->itemID;
int nBakupDC=pDC->SaveDC();//保存DC 的状态
LV_ITEM lvi;
lvi.mask=LVIF_IMAGE|LVIF_STATE;
lvi.iItem=nItem;
lvi.iSubItem=0;
lvi.stateMask=0xffff;//获取所有的状态标志
GetItem(&lvi);
//判断是否需要加亮显示
BOOL bHighlight=(lvi.state & LVIS_DROPHILITED) ||((lvi.state & LVIS_SELECTED) && ((GetFocus()==this) ||(GetStyle() & LVS_SHOWSELALWAYS)));
CRect rcBounds,rcLabel,rcIcon;
//如果想知道下面三个调用获得的区域位置，可以用CDC的FillRect函数显示看一下
GetItemRect(nItem,&rcBounds,LVIR_BOUNDS);
GetItemRect(nItem,&rcLabel,LVIR_LABEL);
GetItemRect(nItem,&rcIcon,LVIR_ICON);
//需要按照顺序显示，首先绘制背景
if(bHighlight)
{
pDC->SetTextColor(::GetSysColor(COLOR_HIGHLIGHTTEXT));
pDC->FillRect(rcBounds,&CBrush(::GetSysColor(COLOR_HIGHLIGHT)));
}
else
{
pDC->SetTextColor(::GetSysColor(COLOR_WINDOWTEXT));
pDC->FillRect(rcBounds,&CBrush(::GetSysColor(COLOR_WINDOW)));
}
CString strItem;
LV_COLUMN lvc;
UINT uJustify=DT_LEFT;
lvc.mask=LVCF_FMT|LVCF_WIDTH;
//背景绘制完后输出文字
strItem=GetItemText(nItem,0);
pDC->DrawText(strItem,-1,rcLabel,uJustify |DT_SINGLELINE| DT_NOPREFIX | DT_VCENTER |DT_END_ELLIPSIS);
for(int i=1;GetColumn(i,&lvc);i++)
{
switch(lvc.fmt & LVCFMT_JUSTIFYMASK)
{
case LVCFMT_RIGHT:
uJustify=DT_RIGHT;
break;
case LVCFMT_CENTER:
uJustify=DT_CENTER;
break;
default:
break;
}
rcLabel.left=rcLabel.right;
rcLabel.right=rcLabel.left + lvc.cx;
strItem=GetItemText(nItem,i);
pDC->DrawText(strItem,-1,rcLabel,uJustify |DT_SINGLELINE| DT_NOPREFIX | DT_VCENTER |DT_END_ELLIPSIS);
}
pDC->RestoreDC(nBakupDC);//恢复原来的DC状态
}
我這有一個例子,你試一下...我是可以的
