创建新图层

以下代码从数据库中获取图层符号表，创建新的图层表记录，并将其命名为 （ASDK_MYLAYER）。然后将图层表记录添加到图层表中。

void
createNewLayer()
{
    AcDbLayerTable *pLayerTable;
    acdbHostApplicationServices()->workingDatabase()
        ->getSymbolTable(pLayerTable, AcDb::kForWrite);
    AcDbLayerTableRecord *pLayerTableRecord =
        new AcDbLayerTableRecord;
    pLayerTableRecord->setName("ASDK_MYLAYER");
    // Defaults are used for other properties of 
    // the layer if they are not otherwise specified.
    //
    pLayerTable->add(pLayerTableRecord);
    pLayerTable->close();
    pLayerTableRecord->close();
}
