void gtk_directory_list_set_io_priority ( GtkDirectoryList* self, int io_priority )
Sets the IO priority to use while loading directories.
Setting the priority while
self is loading will reprioritize the
ongoing load as soon as possible.
The default IO priority is
G_PRIORITY_DEFAULT, which is higher than
the GTK redraw priority. If you are loading a lot of directories in
parallel, lowering it to something like
may increase responsiveness.
