Re: questionfor progress bar

["Kim Jongha" <kim jongha gmail com>]

Oops, It doesn't work, What's the problem.. ?

I describe in detail.

/* pseudo code*/

gboolean * show_bar_idle_cb(pointer  val)
{
 gtk_progress_bar_set_fraction(POINT_TO_INT(val));
 return FALSE to exit the idle

}
/* and the for loop */
double val;
for(i = 0; i< SOME_NUMBER; i++)
{
  val = (100.0 /SOME_NUMBER)* i /100.0;
  g_idle_add(show_bar_idle_cb, INT_TO_POINT(val));
**SOMEWORK**
}

The problem is that timeout events don't occured before finishing
SOMEWORK(read file with fscanf) . so I can see only the progress bar
that fully filled and nothing filled.

--------------
double val = 0;
  g_idle_add(show_bar_idle_cb, INT_TO_POINT(val));
for(i = 0; i< SOME_NUMBER; i++)
{
  val = (100.0 /SOME_NUMBER)* i /100.0;
**SOMEWORK**
}
--------------
upper codes don't work too.
