richedit实现超链接

刚在做小飞鸽的文件传送，要在richeidt上提示：XXX向你发送了XX文件，是 否接收，是和否都要使用超链接，

贴个代码吧：

[cpp]
view plaincopyprint?

int nTotalLen = m_EidtRecod.GetWindowTextLength();
m_EidtRecod.SetSel(nTotalLen, nTotalLen);
CString str;
str.Format(_T("%s 向你发送文件:%s 是否接受?\r\n "), m_szName, pFile->m_szName);
m_EidtRecod.ReplaceSel((LPCTSTR)str);

CHARFORMAT cf = {0};
cf.cbSize = sizeof(CHARFORMAT);
cf.dwMask = CFM_COLOR|CFM_FACE|CFM_SIZE|CFM_UNDERLINE|CFM_UNDERLINETYPE|CFM_LINK
cf.dwEffects = CFE_LINK|CFE_UNDERLINE;
cf.crTextColor = RGB(255, 0, 0);

// 设置超链接
nTotalLen = m_EidtRecod.GetWindowTextLength();
str.Format(_T("(Yes)是"));
m_EidtRecod.ReplaceSel((LPCTSTR)str);
int iEndPos = m_EidtRecod.GetWindowTextLength();
m_EidtRecod.SetSel(iEndPos-10, iEndPos);
m_EidtRecod.SetSelectionCharFormat(cf);

// 设置超链接
m_EidtRecod.SetSel(iEndPos, iEndPos);
m_EidtRecod.ReplaceSel(_T(" "));
nTotalLen = m_EidtRecod.GetWindowTextLength();
m_EidtRecod.ReplaceSel(_T("(No)否"));
iEndPos = m_EidtRecod.GetWindowTextLength();
m_EidtRecod.SetSel(iEndPos-10, iEndPos);
m_EidtRecod.SetSelectionCharFormat(cf);

m_EidtRecod.SetSel(iEndPos, iEndPos);
m_EidtRecod.ReplaceSel(_T("\r\n"));

// 使RichEdit响应ENM_LINK事件

m_EidtRecod.SetEventMask(ENM_LINK);
m_EidtRecod.LineScroll(1);

int nTotalLen = m_EidtRecod.GetWindowTextLength();
m_EidtRecod.SetSel(nTotalLen, nTotalLen);
CString str;
str.Format(_T("%s 向你发送文件:%s 是否接受?\r\n        "), m_szName, pFile->m_szName);
m_EidtRecod.ReplaceSel((LPCTSTR)str);

CHARFORMAT cf = {0};
cf.cbSize = sizeof(CHARFORMAT);
cf.dwMask = CFM_COLOR|CFM_FACE|CFM_SIZE|CFM_UNDERLINE|CFM_UNDERLINETYPE|CFM_LINK
cf.dwEffects = CFE_LINK|CFE_UNDERLINE;
cf.crTextColor = RGB(255, 0, 0);

// 设置超链接
nTotalLen = m_EidtRecod.GetWindowTextLength();
str.Format(_T("(Yes)是"));
m_EidtRecod.ReplaceSel((LPCTSTR)str);
int iEndPos = m_EidtRecod.GetWindowTextLength();
m_EidtRecod.SetSel(iEndPos-10, iEndPos);
m_EidtRecod.SetSelectionCharFormat(cf);

// 设置超链接
m_EidtRecod.SetSel(iEndPos, iEndPos);
m_EidtRecod.ReplaceSel(_T("           "));
nTotalLen = m_EidtRecod.GetWindowTextLength();
m_EidtRecod.ReplaceSel(_T("(No)否"));
iEndPos = m_EidtRecod.GetWindowTextLength();
m_EidtRecod.SetSel(iEndPos-10, iEndPos);
m_EidtRecod.SetSelectionCharFormat(cf);

m_EidtRecod.SetSel(iEndPos, iEndPos);
m_EidtRecod.ReplaceSel(_T("\r\n"));

// 使RichEdit响应ENM_LINK事件
m_EidtRecod.SetEventMask(ENM_LINK);
m_EidtRecod.LineScroll(1);

父类加个消息映射:

[cpp]
view plaincopyprint?

afx_msg void OnLink(LPNMHDR pnmh, LRESULT *pResult);

afx_msg void OnLink(LPNMHDR pnmh, LRESULT *pResult);

[cpp]
view plaincopyprint?

ON_NOTIFY(EN_LINK, IDC_RICHEDIT_RECODE, OnLink)

ON_NOTIFY(EN_LINK, IDC_RICHEDIT_RECODE, OnLink)

[cpp]
view plaincopyprint?

void XXX::OnLink(LPNMHDR pnmh, LRESULT *pResult) { ENLINK *pEnLink = (ENLINK *)pnmh; if(pEnLink->msg == WM_LBUTTONDOWN) { m_EidtRecod.SetSel(pEnLink->chrg); CString strLink = m_EidtRecod.GetSelText(); if (-1 != strLink.Find(_T("是"))) { } else if(-1 != strLink.Find(_T("否"))) { } } pResult = 0; }

void XXX::OnLink(LPNMHDR pnmh, LRESULT *pResult)
{
ENLINK *pEnLink = (ENLINK *)pnmh;
if(pEnLink->msg == WM_LBUTTONDOWN)
{
m_EidtRecod.SetSel(pEnLink->chrg);
CString strLink = m_EidtRecod.GetSelText();

if (-1 != strLink.Find(_T("是")))
{

}
else if(-1 != strLink.Find(_T("否")))
{

}

}

pResult = 0;

}

也可以子类化richeidt,通过消息反射函数。

再贴个超链接通用的代码吧:

[cpp]
view plaincopyprint?

DWORD Mask = m_edit.GetEventMask(); Mask = Mask | ENM_LINK | ENM_MOUSEEVENTS | ENM_SCROLLEVENTS | ENM_KEYEVENTS; m_edit.SetEventMask(Mask); ::SendMessage(m_edit.m_hWnd, EM_AUTOURLDETECT, true, 0); m_edit.SetWindowText(_T("12222 www.baidu.com ooooie\r\nddfdf www.baidu.com kkkdkf"));

DWORD Mask = m_edit.GetEventMask();
Mask = Mask | ENM_LINK  | ENM_MOUSEEVENTS | ENM_SCROLLEVENTS | ENM_KEYEVENTS;
m_edit.SetEventMask(Mask);
::SendMessage(m_edit.m_hWnd, EM_AUTOURLDETECT, true, 0);

m_edit.SetWindowText(_T("12222 www.baidu.com ooooie\r\nddfdf www.baidu.com kkkdkf"));

这样所有的www.什么的都变蓝色加下划线

再加个响应代码

[cpp]
view plaincopyprint?

ON_NOTIFY(EN_LINK, IDC_RICHEDIT21, OnLink)

ON_NOTIFY(EN_LINK, IDC_RICHEDIT21, OnLink)

[cpp]
view plaincopyprint?

void XXXDlg::OnLink(LPNMHDR pnmh, LRESULT *pResult)
{
ENLINK* pLink = ( ENLINK* )pnmh ;
*pResult = 0;
switch (pLink->msg)
{
case WM_LBUTTONDOWN://如果鼠标左键被点击

{
CString strURL;
CHARRANGE crCharRange;
CRichEditCtrl * pTempEdit = (CRichEditCtrl*)CRichEditCtrl::FromHandle(pLink->nmhdr.hwndFrom);
pTempEdit->GetSel(crCharRange); //得到原来选中的字符

pTempEdit->SetSel(pLink->chrg); //设置RUL被选中

strURL = pTempEdit->GetSelText(); //得到URL

pTempEdit->SetSel( crCharRange ); //恢复原来被选中的字符

CWaitCursor l_WaitCursor ; //用当前默认的浏览器打URL

ShellExecute(this->GetSafeHwnd(), _T("open"), strURL, NULL, NULL, SW_SHOWNORMAL);
*pResult = 1;
}
break ;

case WM_LBUTTONUP:
{
*pResult = 1;
}
break ;

default:
break ;
}
}

void XXXDlg::OnLink(LPNMHDR pnmh, LRESULT *pResult)
{
ENLINK* pLink = ( ENLINK* )pnmh ;
*pResult = 0;
switch (pLink->msg)
{
case WM_LBUTTONDOWN://如果鼠标左键被点击
{
CString strURL;
CHARRANGE crCharRange;
CRichEditCtrl * pTempEdit = (CRichEditCtrl*)CRichEditCtrl::FromHandle(pLink->nmhdr.hwndFrom);
pTempEdit->GetSel(crCharRange);		//得到原来选中的字符
pTempEdit->SetSel(pLink->chrg);		//设置RUL被选中

strURL = pTempEdit->GetSelText();	//得到URL
pTempEdit->SetSel( crCharRange );	//恢复原来被选中的字符
CWaitCursor l_WaitCursor ;			//用当前默认的浏览器打URL
ShellExecute(this->GetSafeHwnd(), _T("open"), strURL, NULL, NULL, SW_SHOWNORMAL);
*pResult = 1;
}
break ;

case WM_LBUTTONUP:
{
*pResult = 1;
}
break ;

default:
break ;
}
}

收工.
