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); printf("Exiting
StartScan.\n"); //main.cpp, Line 129 return; } I get to Scanning() okay but I don't exit on_StartScan_activeat() until I exit Scanning() (not what I expected). Worse still when I step through Scanning as I exit I get (gdb) next
(main:24011): GLib-CRITICAL **: g_idle_add_full: assertion `function != NULL' failed on_StartScan_activate () at main.cpp:129 (gdb) next Exiting StartScan.
guint Scanning(void) { while(1 == scan_on_fg) { //Bean counting with rest of GUI in control, I hoped. } return(FALSE); //Remove this thread. }
Regards Ian. |
