Hi all,
Sorry to bother but I'm lost with the workings of
guint g_idle_add ()
My code is as
follows
extern C
void on_StartScan_activate() //from gtk menu item
{ printf(Start Scan Activated. \n);
scan_on_fg =1;
Scanning_lvl = g_idle_add((GSourceFunc) Scanning(), (gpointer) 0);
hi,
Scanning() is being called as part of g_idle_add(). Scanning() returns
FALSE, which = NULL in C, so your call to g_idle_add() at execution time
resolves to:
g_idle_add((GSourceFunc) 0, (gpointer) 0);
this clearly won't work.
rewrite as:
Scanning_lvl = g_idle_add((GSourceFunc) Scanning,

Thanks for your reply Richard.
Yes, I know that. I thought Scanning() was a lower level than the
gtk window and thus the StartScan_active() would exit before the
mainloop would add Scanning() and then only execute
Thanks Chris,
I think that not only is my code broken my idea on how to do what I
want is broken. I must fix that before I start on the code.
My starting point was two button, scan off and scan on in glade.
Scan on sets a flag and it scans til the off button is pressed. So the
off
