hio_dwg

Fields

bool bDWGInitialized

Detailed Description

class hio_dwg : public HInputHandler

The hio_dwg is used for reading DWG files. This utility only supports basic geometry nodes from DWG specification. This is not meant to be a DWG import tool, but the main objective is to provide the developers with a sample code.

Public Functions

HFileIOResult FileInputByKey(wchar_t const *FileName, HC_KEY key, HInputHandlerOptions *options)

This method reads the DWG/DXF file ‘filename’ into the segment tree underneath key.

Parameters:
  • filename – The name of the file to load.
  • key – The HOOPS segment key to load model data into.
  • options – An options class containing any needed extra information for operation.
Returns:

The #HFileInputResult result of the input operation.

virtual HFileIOResult FileInputByKey(char const *FileName, HC_KEY key, HInputHandlerOptions *options)

This method loads model data from a given file to a given HOOPS segment key. Note that this must be implemented in a subclassed HInputHandler instance handling models.

Parameters:
  • filename – The name of the file to load.
  • key – The HOOPS segment key to load model data into.
  • options – An options class containing any needed extra information for the operation.
Returns:

The #HFileInputResult result of the input operation.

virtual HFileIOResult FileInputByKey(unsigned short const *FileName, HC_KEY key, HInputHandlerOptions *options)

This method loads model data from a given file to a given HOOPS segment key. Note that this must be implemented in a subclassed HInputHandler instance handling models.

Parameters:
  • filename – The UNICODE name of the file to load.
  • key – The HOOPS segment key to load model data into.
  • options – An options class containing any needed extra information for the operation.
Returns:

The #HFileInputResult result of the input operation.

HFileIOResult DatabaseInputByKey(AcDbDatabase *pAcDbDatabase, HC_KEY key, HInputHandlerOptions *options)

This method reads the AcDbDatabase objects into the segment tree underneath the key.

Parameters:
  • pAcDbDatabase – A pointer to the AcDbDatabase which is required to be imported to HOOPS.
  • key – The HOOPS key to the segment for data to load in.
  • options – An options class containing any needed extra information for operation.
Returns:

The #HFileInputResult result of the input operation.

hio_dwg()
~hio_dwg()
virtual void RegisterInputHandlerTypes()

This method registers the “dwg” and “dxf” extensions to this handler as an input handler.

virtual char const *GetInputName()
Returns:A character pointer denoting the name of the handler.
virtual char const *GetInputTypesString()
Returns:The input extension type that is handled by hio_dwg which are “dwg” and “dxf”.
virtual HInputHandlerStyle GetInputStyle()
Returns:The type of input style which is HInputHandlerStyleModel.
