[OT]GTKmm widget animation

[Shuo Xiang]

Greetings:

I'm sorry that this is off-topic because I can't post to the GTKmm mailing
list for some reason.

I am trying to animate the moving of a poker card from one point in the
window to another. The poker card is of type Gtk::Image and is included in
a container of type Fixed (i.e. it allows for absolute x/y positioning of
its child widgets). I continuously called "Fixed.move()" on the poker card
with new x/y coordinates but nothings gets shown except the position afte
rthe final call to Fixed.move(). Why is it like that? How can I force a
redraw of the poker card in its new position after each call to
Fixed.move()?

Regards,

Shuo
