Thanks for the advice - I've found some old BeOS sample code ("Miszsa's
crazy apps - slidy window demo") using BMessageRunner and I'm trying to play
with the interval parameter.
I'm seeing that it doesn't make a difference how short I make the interval
parameter, if the number of pixels to resize by on each call to resize is
large, than the total time of the animation seems the same to the eye
regardless of the time interval.
The only way to speed up the total animation time is to make the resize by
steps larger (i.e. resize by more pixels at a time).
So - if I want to be able to control the overall animation time, I will need
to "jump" more distance on each resize call.
Thanks,
hey68you
