The VECTOREVENT structure holds information about an event.

Members

L_INT nSize

Size of this structure. Used for versioning.

L_UINT uType

The type of event that was generated. For a list of possible values, refer to the Comments section below.

VECTOR_EVENT_STATUS Status

Status of the event. Possible values are:

Value Meaning
VECTOR_EVENT_STATUS_BEFORE The action that generated the event is about to be taken.
VECTOR_EVENT_STATUS_AFTER The action that generated the event was just completed.

L_INT nErrorCode

Error code associated with the event. For a list of possible values, refer to the Return Codes.

pVECTOROBJECT pObject

Pointer to the vector object associated with the event. This structure member is only valid for certain event types. For a list of the events for which this member is valid, refer to the table in the Comments section below.

L_VOID pObjectDesc

Pointer to an object descriptor. This structure is only valid for certain event types. For a list of the events for which this member is valid, refer to the table in the Comments section below.

pVECTORLAYER pLayer

Pointer to the vector layer associated with the event. This structure member is only valid for certain event types. For a list of the events for which this member is valid, refer to the table in the Comments section below.

pVECTORLAYERDESC pLayerDesc

Pointer to a layer descriptor. This structure is only valid for certain event types. For a list of the events for which this member is valid, refer to the table in the Comments section below.

pVECTORGROUP pGroup

Pointer to the vector group associated with the event. This structure member is only valid for certain event types. For a list of the events for which this member is valid, refer to the table in the Comments section below.

pVECTORGROUPDESC pGroupDesc

Pointer to a group descriptor. This structure is only valid for certain event types. For a list of the events for which this member is valid, refer to the table in the Comments section below.

pVECTORPOINT pPoint1

Pointer to a general point 1. This structure is only valid for certain event types. For a list of the events for which this member is valid, refer to the table in the Comments section below.

pVECTORPOINT pPoint2

Pointer to a general point 2. This structure is only valid for certain event types. For a list of the events for which this member is valid, refer to the table in the Comments section below.

L_UINT32 dwFlags

Flag that provides processing information. This member is only valid for certain event types. For a list of the events for which this member is valid, refer to the table in the Comments section below.

L_VOID *pUserData

User defined data.

Comments

The uType member will correspond to the vector function called, for example if you call LVectorBase::Empty, an event of type VECTOR_EVENT_EMPTY will be fired.

The following table lists all the defined event types plus values for the structure variables, when defined. Not all structure members are defined for every event. For example, the Object member is not defined for a VECTOR_EVENT_FREE event, but it is defined for the VECTOR_EVENT_TRANSLATION event. The data contained in the Object structure member corresponds to the vector object that was translated. More information can be obtained by using the pObject as an argument to an LVectorObject constructor, or to a constructor of a derived class of LVectorObject (i.e. LVectorRectangle.)

The pVECTOROBJECT(pObject), pVECTORGROUP(pGroup), pVECTORLAYER(pLayer) pointers can all be passed to class library constructors to create class library objects. The LVectorObject (and derived classes of LVectorObject) has a constructor that takes a pVECTOROBJECT, the LVectorGroup has a constructor that takes a pVECTORGROUP, and the LVectorLayer class has a constructor that takes a pVECTORLAYER.
