[gtkmm] Help me!!! (about threads and refresh)

[MIGUELMMC <MIGUELMMC terra es>]

Hello.

I need help.

I am trying to paint images with create_from_xpm_data and
Gtk::Image::set..., but the window is not refreshing (like
Update_Data(true or false) in MS-Windows) under these circumstances:

If //pixmap1->set(brkpt) window refreshes good.
If pixmap1->set(brkpt):
     If usleep(x) -> x is > 500000 more or less: good
     If usleep(x) -> x is < 500000 or another value small: Freezed!

What is wrong?
Thanks in advance.

Here is the code:
(sorry, a lot of lines :( )
