Detailed Description

A class to monitor events from the C++ side of things. It maintains a set of "hooks", function pointers assigned to event names, and calls the appropriate hooks when the matching event is detected.

This class is not necessary when the hooks are detected and processed entirely by the scripting language, e.g. via Scheme hooks or the messenger in Python.

◆ __init__()

__init__ ( EventQueue  ev_queue)

◆ dispatchEvent()

dispatchEvent ( const Event  )

Calls the hooks assigned to the indicated single event.

◆ getClassType()

static TypeHandle getClassType ( )

◆ getGlobalEventHandler()

static EventHandler getGlobalEventHandler ( EventQueue  queue)
static

Returns a pointer to the one global EventHandler object. If the global object has not yet been created, this will create it.

◆ processEvents()

processEvents ( )

The main processing loop of the EventHandler. This function must be called periodically to service events. Walks through each pending event and calls its assigned hooks.

◆ write()

write ( Ostream  out)
