关于TabCtrl，请各位指教。高分奉送……

如何改变背景（颜色或者添加图象），如何改变字体颜色……我继承了一个CTabCtrl类。是不是在BOOL CMyTabCtrl::OnEraseBkgnd(CDC* pDC) 中实现？最好给出代码实例！谢谢了先。

CTabCtrl::DrawItem
void DrawItem( LPDRAWITEMSTRUCT lpDrawItemStruct );
By default, this member function does nothing. Override this member function to implement drawing for an owner-draw CTabCtrl object.
The application should restore all graphics device interface (GDI) objects selected for the display context supplied in lpDrawItemStruct before this member function terminates.

也可以override OnDrawItem() of the parent window:
Override the OnDrawItem() method for your CDialog derived class using Class
Wizard and add the following code, changing variable names as neccessary. It is
important to note that a pointer to a CDC object from the handle of the DC
passed in via the LPDRAWITEMSTRUCT is required, otherwise only the background of
the text will be the desired color.

void CMyDialogDlg::OnDrawItem(int nIDCtl, LPDRAWITEMSTRUCT lpdis)
{
// TODO: Add your message handler code here and/or call default

char szTabText[100];
UINT bkColor;
CBrush *cbr;
TC_ITEM tci;
LOGBRUSH m_LogBrush;

CTabCtrl *pTabCtrl = (CTabCtrl *)GetDlgItem(IDC_TAB1);

if (pTabCtrl->m_hWnd == lpdis->hwndItem)
{
// To determine which tab to be drawn. I assume you only have two tabs
switch (lpdis->itemID)
{
case 0:
cbr = &m_brRed;
cbr->GetLogBrush(&m_LogBrush);
bkColor = m_LogBrush.lbColor;
break;

case 1:
cbr = &m_brBlue;
cbr->GetLogBrush(&m_LogBrush);
bkColor = m_LogBrush.lbColor;
break;
}

memset(szTabText, '\0', sizeof(szTabText));
tci.mask = TCIF_TEXT;
tci.pszText = szTabText;
tci.cchTextMax = sizeof(szTabText)-1;

pTabCtrl->GetItem(lpdis->itemID, &tci);

CDC *dc = CDC::FromHandle(lpdis->hDC);
dc->FillRect(&lpdis->rcItem, cbr);
dc->SetBkColor(bkColor);

TextOut(lpdis->hDC,
lpdis->rcItem.left,
lpdis->rcItem.top,
tci.pszText,
lstrlen(tci.pszText));
}
// CDialog::OnDrawItem(nIDCtl, lpdis);
}

兄弟愚钝，&m_brRed是如何得到的？

[masterz]

m_brRed定义成CMyDialogDlg的成员呀

[alfwolf]

请问我该如何想其中加入图标呢？各位帮帮忙，很着急！！！
分数还可以增加！

[masterz]

void CMyTab::DrawItem( LPDRAWITEMSTRUCT lpdis )
{
char szTabText[100];
UINT bkColor;
CBrush *cbr;
TC_ITEM tci;
LOGBRUSH m_LogBrush;
if(lpdis->itemID%2)
{
cbr = &m_brRed;
cbr->GetLogBrush(&m_LogBrush);
bkColor = m_LogBrush.lbColor;
}
else
{
cbr = &m_brBlue;
cbr->GetLogBrush(&m_LogBrush);
bkColor = m_LogBrush.lbColor;
}
memset(szTabText, '\0', sizeof(szTabText));
tci.mask = TCIF_TEXT;
tci.pszText = szTabText;
tci.cchTextMax = sizeof(szTabText)-1;

GetItem(lpdis->itemID, &tci);
FillRect(lpdis->hDC,&lpdis->rcItem,*cbr);
::SetBkColor(lpdis->hDC,bkColor);
HICON hicon=LoadIcon(AfxGetApp()->m_hInstance,MAKEINTRESOURCE(IDR_MAINFRAME));
DrawIcon(lpdis->hDC,lpdis->rcItem.left,lpdis->rcItem.top,hicon);//DrawIconEx is more useful
DeleteObject(hicon);
TextOut(lpdis->hDC,
lpdis->rcItem.left+32,//leave room for icon width
lpdis->rcItem.top,
tci.pszText,
lstrlen(tci.pszText));

}

谢谢masterz(）大哥。
分数全部给你吧，那两个兄弟我另外给吧！
可否留下email，以后好向大哥学习！

[alfwolf]

那么我想加入图标应该如何来做呢？
