I was fooling around some with gdk_input_add, and got it to do
some pretty cool things. (I wrote a mini FTP client in Perl that
forks off a child to do a get, and asynchronously updates a progress
bar based on information received back from the child.) But I
think the interface should be made consistent with gtk_timeout_add,
and gtk_idle_add. (Largely to make things easier for writing non-C
bindings.)
The prototype for the callback function is now:
typedef void (*GdkInputFunction) (gpointer data,
gint source,
GdkInputCondition condition);
I think it should be:
typedef gint (*GdkInputFunction) (gint source,
GdkInputCondition condition);
gpointer data);
Moving the gpointer argument to the end allows code-sharing in
callback-handling glue code.
Checking the return and removing the handler if it is non-zero
would be a nice consistency thing. I'd be happy to make the changes
if they were considered appropriate.
Regards,
Owen
