MFC应用实例：[41]Rich Edit使用

1、新建一个基于对话框的应用程序，工程名为BaseRichEdit。

2、如下图为对话框添加一个Rich Edit控件和一个按钮，三个复选框，三个单选按钮。

3、双击“设置字体颜色”按钮添加响应函数OnTextColor()，修改其响应函数OnTextColor()如下：void CBaseRichEditDlg::OnTextColor(){ // TODO: Add your control notification handler code here CHARFORMAT cf; memset (&cf, '\0', sizeof (CHARFORMAT)); cf.dwMask = CFM_COLOR; m_RichSample.GetSelectionCharFormat (cf); CColorDialog cc (cf.crTextColor);// cc.m_cc.lpCustColors = m_clrCustom; if (cc.DoModal () == IDCANCEL) return; cf.dwMask = CFM_COLOR; cf.dwEffects &= ~CFE_AUTOCOLOR; cf.crTextColor = cc.GetColor (); m_RichSample.SetSelectionCharFormat (cf); m_RichSample.SetFocus ();}

4、为三个复选按钮分别添加磨蓄贺痞响应函数，添加函数如下：void CBaseRichEditDlg::OnBold() //设置粗体复碚枞凇悄选框{ // TODO: Add your control notification handler code here CHARFORMAT cf;//结构体 m_RichSample.GetSelectionCharFormat (cf); cf.dwMask |= CFM_BOLD; cf.dwEffects ^= CFE_BOLD; m_RichSample.SetSelectionCharFormat (cf); if (cf.dwEffects & CFE_BOLD)//当前为粗体 m_ctlBold.SetCheck (1);//设置按钮被选中 else//当前不为粗体 m_ctlBold.SetCheck (0);//设置按钮未被选中 m_RichSample.SetFocus ();}void CBaseRichEditDlg::OnItalic() //设置斜体复选框{ // TODO: Add your control notification handler code here CHARFORMAT cf; m_RichSample.GetSelectionCharFormat (cf); cf.dwMask |= CFM_ITALIC; cf.dwEffects ^= CFE_ITALIC; m_RichSample.SetSelectionCharFormat (cf); if (cf.dwEffects & CFM_ITALIC)//当前为斜体 m_ctlItalic.SetCheck (1);//设置按钮被选中 else//当前不为斜体 m_ctlItalic.SetCheck (0);//设置按钮未被选中 m_RichSample.SetFocus (); }void CBaseRichEditDlg::OnUnderline() //设置下划线复选框{ // TODO: Add your control notification handler code here CHARFORMAT cf; m_RichSample.GetSelectionCharFormat (cf); cf.dwMask |= CFM_UNDERLINE; cf.dwEffects ^= CFE_UNDERLINE; m_RichSample.SetSelectionCharFormat (cf); if (cf.dwEffects & CFM_UNDERLINE)//当前带有下划线 m_ctlUnderline.SetCheck (1);//设置按钮被选中 else//当前不带有下划线 m_ctlUnderline.SetCheck (0);//设置按钮未被选中 m_RichSample.SetFocus ();}

5、为三个单选按钮分别添加磨蓄贺痞响应函数，添加函数如下：void CBaseRichEditDlg::OnLett(){ // TOD晦倘佳鳎O: Add your control notification handler code here PARAFORMAT pf; m_RichSample.GetParaFormat(pf); pf.dwMask = PFM_ALIGNMENT; pf.wAlignment = PFA_LEFT; m_RichSample.SetParaFormat(pf); m_RichSample.SetFocus ();}void CBaseRichEditDlg::OnRight(){ // TODO: Add your control notification handler code here PARAFORMAT pf; m_RichSample.GetParaFormat(pf); pf.dwMask = PFM_ALIGNMENT; pf.wAlignment = PFA_RIGHT; m_RichSample.SetParaFormat(pf); m_RichSample.SetFocus ();}void CBaseRichEditDlg::OnCenter(){ // TODO: Add your control notification handler code here PARAFORMAT pf; m_RichSample.GetParaFormat(pf); pf.dwMask = PFM_ALIGNMENT; pf.wAlignment = PFA_CENTER; m_RichSample.SetParaFormat(pf); m_RichSample.SetFocus ();}

6、程序运行如下
