threadsAddTimeoutFull

Sets a function to be called at regular intervals holding the GDK lock, with the given priority. The function is called repeatedly until it returns FALSE, at which point the timeout is automatically destroyed and the function will not be called again. The notify function is called when the timeout is destroyed. The first call to the function will be at the end of the first interval.

Note that timeout functions may be delayed, due to the processing of other event sources. Thus they should not be relied on for precise timing. After each call to the timeout function, the time of the next timeout is recalculated based on the current time and the given interval (it does not try to “catch up” time lost in delays).

This variant of Timeout.addFull can be thought of a MT-safe version for GTK+ widgets for the following use case:

static gboolean timeout_callback (gpointer data)
{
SomeWidget *self = data;

// do stuff with self

self->timeout_id = 0;

return G_SOURCE_REMOVE;
}

static void some_widget_do_stuff_later (SomeWidget *self)
{
self->timeout_id = g_timeout_add (timeout_callback, self)
}

static void some_widget_finalize (GObject *object)
{
SomeWidget *self = SOME_WIDGET (object);

if (self->timeout_id)
g_source_remove (self->timeout_id);

G_OBJECT_CLASS (parent_class)->finalize (object);
}
