Function gdk:display-sync
Lambda Listgdk:display-sync (display) ArgumentsDetails    
    Flushes any requests queued for the windowing system and waits until all
    requests have been handled.  
  This is often used for making sure that the display is synchronized with the  current state of the program. Calling the gdk:display-sync function  before the gdk_error_trap_pop() function makes sure that any errors
  generated from earlier requests are handled before the error trap is removed. This is most useful for X11. On windowing systems where requests are handled synchronously, this function will do nothing.  | See also |
