CAD二次开发学习笔记七(创建文字)

在CreateEnt.h中添加函数声明

//单行文字
static AcDbObjectId CreateText(const AcGePoint3d& ptInsert,const ACHAR* text
    ,AcDbObjectId style = AcDbObjectId::kNull,double height=2.5,double rotation=0);
//多行文字
static AcDbObjectId CreateMText(const AcGePoint3d& ptInsert,const ACHAR* text
    ,AcDbObjectId style = AcDbObjectId::kNull,double height=2.5,double width=10);

 

在CreateEnt.cpp中添加函数实现

//创建文字
AcDbObjectId CCreateEnt::CreateText(const AcGePoint3d& ptInsert,const ACHAR* text
                                    ,AcDbObjectId style,double height,double rotation)
{
    AcDbText *pText = new AcDbText(ptInsert,text,style,height,rotation);
    return CCreateEnt::PostToModelSpace(pText);
}
//多行文字
AcDbObjectId CCreateEnt::CreateMText(const AcGePoint3d& ptInsert,const ACHAR* 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 CCreateEnt::PostToModelSpace(pMText);
}

 

调用

//创建单行文字
AcGePoint3d ptInsert(0,4,0);
CCreateEnt::CreateText(ptInsert,_T("abck中文"));
//创建多行文字
ptInsert.set(0,0,0);
CCreateEnt::CreateMText(ptInsert,_T("http://www.weiqi9d.com"));

显示中文的时候可能会显示成????
可以修改文字样式：格式->文字样式
