gdk_threads_enter() and gdk_threads_leave() (and also g_thread_init() and

Hi All ,
          I am doing a project in it I want to show the lyrics of a song
which is playing in the background .I use gtk label to show that lyrics .I
use the gtk window to show the lyrics on it .I read a file in which I have
that lyrics and the time  at which it come from the start of the play .I
sleep  for that time  I read the next line and display it on the window
with the help of the  label  .I test  that the lyrics are coming in
properly  or  not so I put printf and verify that it read that lyrics
according to that time .But when I try to show that lyrics in label on the
windows It do not change according to time .I mean to say that it changes
but not on the windows .I make 2 threads one for playing the music and other
for showing that lyrics .If I regularly move the mouse cursor on the window
then the lyrics changes accordingly .But if I stay ideal do not move the
mouse cursor on it it do not change the lyrics .I think it do not refresh
after that sleep time on its own .
I do that like follows
                font_desc = pango_font_description_from_string("sans 15");
                gdk_color_parse("#D5D8D4", &color);

I use a while loop to read it to the end of that file .I think I am able
to explain my problem .If there is any option that refresh the windows after
that sleep time I think the lyrics changes properly .the lyrics are changing
If there is any movement  on the windows other wise it do not change .
So there is some refreshing happens when some movement on the windows .But
u can't move the mouse cursor every time .So please tell my there is some
way to refresh that windows Programeticaly .
Thanks in advance .
