Hi Michael,
I am a beginner in Linux programming, and your suggestion works! But I am
still having some problem that the CPU usage is always 100% after the
program starts. Could you please look at my code below and give me some
suggestion?
Thanks a lot!!!
Following is some of my code:
// idle handler of the main loop
gboolean OnIdle(int msgQid)
{
if(thread_signal)
{
RefreshImage();
}
return TRUE;
}
int main (int argc, char *argv[])
{
gnome_program_init (PACKAGE, VERSION, LIBGNOMEUI_MODULE,
argc, argv,
GNOME_PARAM_APP_DATADIR, PACKAGE_DATA_DIR,
NULL);
//register an idle handler to update the image when the background thread
emits a signal
gdk_threads_enter();
g_idle_add(OnIdle, nMsgQID); /* may need some macros here; I'm a
* PyGTK/GTKmm guy, so the C stuff
* isn't my forte */
gdk_threads_leave();
MainWnd = create_MainWnd ();
gtk_widget_show (MainWnd);
gtk_main ();
return 0;
}
