如何修改当前图形中的AcDbText实体，并马上显示出来？

HuaiYu

是不是用这个函数啊?
Acad::ErrorStatus
setTextString(

    const char* newText);

newText        Input null-terminated text string (256 byte max)

This function makes a copy of newText and uses the copy as the text string to display. The string must be a standard null-terminated string and cannot be more than 256 bytes long (not including the null terminator).
Unicode, multicode, and the AutoCAD special characters (%%d, %%p, etc.) are supported in the same fashion as they are when entering a text string at the AutoCAD command line for the text or dtext commands.
The text string is used for DXF group code 1.

Returns Acad::eOk if successful or Acad::eInvalidInput if the data passed in is not acceptable.

刷新整个图形区：
[PHP]
void regen()
{
        actrTransactionManager->queueForGraphicsFlush();
    actrTransactionManager->flushGraphics();
    acedUpdateDisplay();
}[/PHP]
刷新特定实体：
[PHP]
void regen(AcDbObjectId objId)
{
        AcDbEntity *pEnt;
        if(acdbOpenAcDbEntity(pEnt,objId,AcDb::kForWrite)==Acad::eOk)
        {
                pEnt->recordGraphicsModified();
            pEnt->downgradeOpen();
            pEnt->draw();
            pEnt->close();
        }
}
[/PHP]
当然，AcDbText也是一个AcDbEntity.
