force screen refresh/update?

[johnallen]

Hi,

I have

gScreenTextObj = viz.addText3D('',parent=viz.SCREEN, pos=( 0, 0, 0 ) )

and then later in a function that was called following a key press using vizact.onkeydown()

gScreenTextObj.message = "asdf"

Is there anyway I can force the screen update to take place (displaying the new text 'asdf')? At present it waits until the function ends and flow returns to the main loop.

thanks,

John
