qt环境下Mapx组建的编程---------regoin

    map->SetCurrentTool(MapSpace::ToolConstants::miPanTool);//鼠标工具

 /* 显示一个小图标（旗子模样）*/

在加上圆形的图元

 void MainWindow::CMapxInit(){

     pCMapXFeatureFactory = pCMapX->FeatureFactory();
     pCMapXFeaturePoint = pCMapXFeatureFactory->CreateSymbol();

     pCMapXPoint = pCMapXFeaturePoint->Point();
     pCMapXPoint->Set(120.06872,29.35692);
     //算出外接矩形的两个角坐标，一个在X轴上，一个在Y轴上

     pCMapXFeatureCircularRegion = pCMapXFeatureFactory->CreateCircularRegion(miCircleTypeMap,pCMapXPoint->asVariant().value<IDispatch*>(),,,);
     pStyle =  pCMapXFeatureCircularRegion->Style();
     pStyle->SetRegionColor(QColor(,,));

     pCMapXLayer->AddFeature(pCMapXFeatureCircularRegion->asVariant().value<IDispatch*>());

     pCMapX->ZoomTo(,120.06872,29.35692);
 }
