Hi!
Am not sure if this could help you, but I had a similar problem and it was a
matter of threads... so take a look to the functions gtk_threads_enter() and
gtk_threads_leave(). If your code is being executed outside a gtk callback and
you use threads, then you should add gtk_threads_enter() at the begining of the
code you posted and gtk_threads_leave() at the end.
If that doesn't work... maybe there is some kind of "gtk_flush()" or something
like that? I am sorry, I am not an expert... but I hope this could help you.
Best regards.
Cosmo.

label according to timeTo: [EMAIL PROTECTED]: [EMAIL PROTECTED] 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
label=gtk_label_new(lyrics_line); gtk_widget_show(label);
gtk_fixed_put(GTK_FIXED(fixed1),label,150,470);
gtk_widget_set_size_request(label,450,30);
//gtk_misc_set_alignment(GTK_MISC(label),0,0.5); font_desc =
pango_font_description_from_string("sans 15");
gtk_widget_modify_font(label,font_desc);
pango_font_description_free(font_desc);
gdk_color_parse("#D5D8D4", &color);
gtk_widget_modify_fg(label,GTK_STATE_NORMAL,&color);
Sleep(time*100); gtk_widget_hide(label);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 .
