hello, attached is my patch that gives callback functions for framechange, selection change and keypress.
keypress is the most "dangerous" as you can effectivly intercept keystokes and rehook the functionality. it is also the function i am most unsure of technically. i think i may have put this in the wrong function so comments please.
here is some exaple python:
############################
import Blender
from Blender.Draw import *
from Blender.BGL import *
def selchange():
print "got selection"
objs=Blender.Object.GetSelected()
for obj in objs:
print obj.getName()
def keybevent(arg):
print "myotherfunc %i" %arg
if arg==AKEY:
print "AKEY"
return 1
return 0
Blender.CallbackSelectionChange(myfunc)
Blender.CallbackKeyPress(myotherfunc)
def draw():
pass
def event(evt,val):
if (evt==QKEY):
Exit()
def bevent(evt):
pass
Register(draw,event,bevent)
#####################################
cheers
