MainLoop

this this(GMainLoop* gMainLoop, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(MainContext context, bool isRunning): Creates a new #GMainLoop structure.

Destructor

doref MainLoop doref(): Increases the reference count on a #GMainLoop object by one.
getContext MainContext getContext(): Returns the #GMainContext of @loop.
getMainLoopStruct GMainLoop* getMainLoopStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
isRunning bool isRunning(): Checks to see if the main loop is currently being run via g_main_loop_run().
quit void quit(): Stops a #GMainLoop from running. Any calls to g_main_loop_run() for the loop will return.
run void run(): Runs a main loop until g_main_loop_quit() is called on the loop. If this is called for the thread of the loop's #GMainContext, it will process events from the loop, otherwise it will simply wait.
unref void unref(): Decreases the reference count on a #GMainLoop object by one. If the result is zero, free the loop and free all associated memory.

mainCurrentSource Source mainCurrentSource(): Returns the currently firing source for this thread.
mainDepth int mainDepth(): Returns the depth of the stack of calls to g_main_context_dispatch() on any #GMainContext in the current thread. That is, when called from the toplevel, it gives 0. When called from within a callback from g_main_context_iteration() (or g_main_loop_run(), etc.) it returns 1. When called from within a callback to a recursive call to g_main_context_iteration(), it returns 2. And so forth.
poll int poll(GPollFD* fds, uint nfds, int timeout): Polls @fds, as with the poll() system call, but portably. (On systems that don't have poll(), it is emulated using select().) This is used internally by #GMainContext, but it can be called directly if you need to block until a file descriptor is ready, but don't want to run the full main loop.
