MFC 如何更改 CLinkCtrl 的链接文本颜色？

Question

From this post , I have set up the code by putting in the OnInitDialog event:

LITEM* pItem = new LITEM;

pItem->iLink = 0; // Url index is 0    

//LIF_ITEMINDEX is required for iLink, LIF_STATE is required for modifing state
pItem->mask = LIF_ITEMINDEX | LIF_STATE;

//using LIS_DEFAULTCOLORS state
pItem->state = LIS_ENABLED | LIS_FOCUSED | LIS_DEFAULTCOLORS;
pItem->stateMask = LIS_ENABLED | LIS_FOCUSED | LIS_DEFAULTCOLORS;

// Send the LM_SETITEM MESSAGE with pItem
HWND m_hWnd=nil; GetDlgItem(IDC_lbstackoverflow, &m_hWnd);

And from OnCtrlColor event:

pDC->SetTextColor(RGB(255, 0, 0));
pDC->SetBkColor(normal);
pDC->SetDCBrushColor(RGB(255, 255, 255));
return (HBRUSH)GetStockObject(DC_BRUSH);

After the code runs, my result is:

If I click on it, now it works:

But, how I can change text color?

Answer 1

You may not be setting the control state correctly.

Please try the MFC way (it works for me). Add to your dialog class:

CLinkCtrl syslink;

Connect it to the resource ID of your link:

void CMFCApplication4Dlg::DoDataExchange(CDataExchange* pDX)
{
    CDialogEx::DoDataExchange(pDX);
    DDX_Control(pDX, IDC_SYSLINK1, syslink);
}

and in OnInitDialog add this:

syslink.SetItemState(0, LIS_ENABLED | LIS_FOCUSED | LIS_DEFAULTCOLORS, 
    LIS_ENABLED | LIS_FOCUSED | LIS_DEFAULTCOLORS);

I see red link with your code in OnCtlColor .
