Provides the initialization and event loop iteration related
|
|
methods for the Gtk# widget library. Since Gtk# is an event
|
|
driven toolkit, Applications register callbacks against various
|
|
events to handle user input. These callbacks are invoked from
|
|
the main event loop when events are detected.

Runs a single iteration of the main loop. If no events are

waiting to be processed Gtk# will block until the next

event is noticed. If you do not want to block look at <see cref="M:Gtk.Application.RunIteration(System.Boolean)" /> or check if

any events are pending with <see cref="M:Gtk.Application.EventsPending()" /> first.
