设置段落的问题

[宙斯之神]

小弟 用 Richviewedit控件 在其中要实现某行文字的位置问题，可是每次按下按钮后文字的位置不是马上改变，而要等到在键盘上按下个字母才能改变位置 ，代码如下
void __fastcall TForm1::Button1Click(TObject *Sender)
{
if(Sender == Button1)
RVStyle1->ParaStyles->Items[RichViewEdit1->CurParaStyleNo ]->Alignment = rvaLeft;
if(Sender == Button2)
RVStyle1->ParaStyles->Items[RichViewEdit1->CurParaStyleNo ]->Alignment = rvaCenter;
if(Sender == Button3)
RVStyle1->ParaStyles->Items[RichViewEdit1->CurParaStyleNo ]->Alignment = rvaRight;
}
帮小弟看看，分析一下是哪里的原因？多谢！！！

加个REFRESH（）试试

void __fastcall TForm1::Button1Click(TObject *Sender)
{
if( ((TButton *)Sender)->Caption == "Button1" )
RVStyle1->ParaStyles->Items[RichViewEdit1->CurParaStyleNo ]->Alignment = rvaLeft;
if( ((TButton *)Sender)->Caption == "Button2" )
RVStyle1->ParaStyles->Items[RichViewEdit1->CurParaStyleNo ]->Alignment = rvaCenter;
if( ((TButton *)Sender)->Caption == "Button3" )
RVStyle1->ParaStyles->Items[RichViewEdit1->CurParaStyleNo ]->Alignment = rvaRight;
}
