PA_GetAreaEvent

version 2003

PA_GetAreaEvent (params) → PA_AreaEvent

The routine PA_GetAreaEvent returns the event that 4D passes to the area. The code of an external area usually consists of a switch of the event kind received.

Currently, the events that an area can receive are stored in an enum, in the "PublicTypes.h" header file. Refer to the Plug-in Area Tutorial for more information.
