How can I update a GTK+ interface on a periodic event. For example, let's say I wanted to update a text field containing the time every 200 milliseconds. How is this typically done?
Update:
Another question (How one executes a periodic job in gtk application?) mentiones g_timeout_add. Is this the best way to go about doing this? It is said in that thread that it may not be efficient?
This tutorial has an example. (Search for the section titled "A timer example".)
The short answer is "use g_timeout_add".
