关于DrawText的问题

[csdn_tw]

我想调用DrawText在一个canvas上输出文字,但发现DT_VCENTER或DT_BOTTOM无效,这是怎么回事,操作系统是win2000,代码如下:

DrawText(Image1->Canvas->Handle,"test",4,&(Image1->ClientRect),DT_VCENTER)

但是显示的文字出现在做上角,换成DT_BOTTOM也无效,请用过的哥们给看看,谢了

必须加上 DT_SINGLELINE 才有效。
DrawText(Image1->Canvas->Handle,"test",4,&(Image1->ClientRect),DT_VCENTER|DT_SINGLELINE);

DrawText(Image1->Canvas->Handle, "test", 4, &(Image1->ClientRect), DT_VCENTER | DT_SINGLELINE);

试了一下,不行,代码如下:

#include <vcl.h>
#pragma hdrstop

#include "Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
}
//---------------------------------------------------------------------------

void __fastcall TForm1::Button1Click(TObject *Sender)
{
DrawText(Image1->Canvas->Handle,"test",4,&(Image1->ClientRect),DT_VCENTER || DT_SINGLELINE);

}
//---------------------------------------------------------------------------

点完按钮后,"test"在Image1的顶端居中显示

晕。要你用"|"而不是"||"。
