关于RichText的问题：我怎么能设置我插入的字体格式，比如我第一行要插入10号的粗体字颜色为红色，第二行插入5号的普通字体颜色为黑色。我每次设置字体的时候，所有行的字体都一起改变。我怎么能针对某一行的字体进行设置？！？！

举个例子：
void __fastcall TForm1::Button1Click(TObject *Sender)
{
AnsiString str;

str = "Insert 1 line";
RichEdit1->Lines->Insert(0, str);
RichEdit1->SelStart -= str.Length()+2;
RichEdit1->SelLength = str.Length();
RichEdit1->SelAttributes->Size = 10;
RichEdit1->SelAttributes->Style = TFontStyles()<<fsBold;
RichEdit1->SelAttributes->Color = clRed;
RichEdit1->SelLength = 0;

str = "Insert 2 line";
RichEdit1->Lines->Insert(2, str);
RichEdit1->SelStart -= str.Length()+2;
RichEdit1->SelLength = str.Length();
RichEdit1->SelAttributes->Size = 15;
RichEdit1->SelAttributes->Style = TFontStyles();
RichEdit1->SelAttributes->Color = clBlack;
RichEdit1->SelLength = 0;
}

如果我想把字体设置为宋体怎么办？！

[hummerking]

还有一个问题，能不能解释一下下面这条语句
RichEdit1->SelStart -= str.Length()+2;

为什么要加2

[jishiping]

RichEdit1->SelAttributes->Name = "宋体";

首先设置selstart何sellength选中文字
用Richedit->selattributes->name
richedit->selattibutes->color和style.
