如图所示，生成后文字因标尺太短，变成了很多行，如何像右下角那样保持一行？
AcDbObjectId CCreatEnt::AddMText( const AcGePoint3d& ptInsert, const TCHAR* text,
                                                               AcDbObjectId style, double height, double width )
{
      AcDbMText *pMText = new AcDbMText();

      // 设置多行文字的特性
      pMText->setTextStyle(style);
      pMText->setContents(text);
      pMText->setLocation(ptInsert);
      pMText->setTextHeight(height);
      pMText->setWidth(width);
      pMText->setAttachment(AcDbMText::kBottomLeft);

      return CCreatEnt::PostToModelSpace(pMText);
}

         // 创建多行文字
         ptInsert.set(0, 0, 0);
         CCreatEnt::AddMText(ptInsert, TEXT("学习和使用ObjectARX需要付出你的努力."));

请问如何设置才能实现不要换行？

Acad::ErrorStatus

setWidth(

double unnamed);

unnamedInput new text block width constraintSets width to be the maximum width allowed for any line of text. This value is used during word wrap calculations as a maximum. It is possible that none of the lines resulting from word wrap formatting will reach this width value, but no lines will ever go past it.
If width is 0.0, word wrap is disabled.
Returns Acad::eOk if successful or Acad::eInvalidInput if the data passed in is not acceptable.

若没有pMText->setWidth这句，或者pMText->setWidth设置的值为0，则不会有标尺
