mfc 仿qq聊天框显示不同颜色字体，怎么实现

Answer 1

用richedit可实现。
CString strMessage = "Chat Message here."

//获取显示区域空白处，以免他之前选择的格式覆盖之后要显示的字体和颜色

GetDlgItem(IDC_RICHEDIT)->SetSel(-1, -1);

CHARFORMAT2 cfm;

cfm.cbSize = sizeof(cfm);

cfm.crTextColor = clr;

cfm.dwEffects = CFE_BOLD;

cfm.dwMask = bBold ? (CFM_BOLD | CFM_COLOR) : CFM_COLOR;

GetDlgItem(IDC_RICHEDIT)->.SetSelectionCharFormat(cfm);

//添加字符串并设置格式

GetDlgItem(IDC_RICHEDIT)->.SetSel(-1, -1);

GetDlgItem(IDC_RICHEDIT)->.ReplaceSel(strMessage);
