用Bricscad推翻样品

gskelly · 发表于 2011-10-30 09:44:43

只是一个用Bricscad和Drx 3.05(后来改名为Tx)快速否决样本。
display cords图层上的点被否决以显示它们的坐标。
请参阅代码、图片和附件
appload DrxOverrule.tx以运行

bool OverRuleSample::onFilteredLayer(const OdDbPoint *point) const
{
    if(point)
    {
        OdDbLayerTableRecordPtr pLayer = point->layerId().safeOpenObject();
        return _tcsicmp(pLayer->getName(),_T("DisplayCords")) == 0;
    }
    return false;
}
double OverRuleSample::getTextHeight(const OdDbPoint *point) const
{
    if(point)
    {
        const OdDbDatabase * pDatabase = point->database();
        OdDbTextStyleTableRecordPtr pStyle = pDatabase->getTextStyleStandardId().safeOpenObject();
        return pStyle->textSize();
    }
    return 0.0;
}
bool OverRuleSample::worldDraw( const OdGiDrawable *drawable, OdGiWorldDraw *wd )
{
    OdDbPoint *point = OdDbPoint::cast(drawable);
    if(point && onFilteredLayer(point))
    {
        const double tsize = getTextHeight(point); 
        const OdGePoint3d pnt = point->position();
        m_text.format(_T("X=%f Y=%f Z=%f"),pnt.x,pnt.y,pnt.z);
        wd->geometry().text(pnt,point->normal(),point->normal().perpVector(),tsize,tsize*m_text.getLength(),0.0,m_text);
    }
    return OdGiDrawableOverrule::worldDraw(drawable,wd);
}
bool OverRuleSample::isApplicable( const OdRxObject* pOverruledSubject ) const
{
    return true;
}
