MainLoop

The GMainLoop struct is an opaque data type representing the main event loop of a GLib or GTK+ application.

class MainLoop {

GMainLoop* gMainLoop;

protected

bool ownedRef;

GMainLoop* getMainLoopStruct(bool transferOwnership);

void* getStruct();

this(GMainLoop* gMainLoop, bool ownedRef);

this(MainContext context, bool isRunning);

MainContext getContext();

bool isRunning();

MainLoop ref_();

void unref();

static Source mainCurrentSource();

static int mainDepth();

static int poll(GPollFD* fds, uint nfds, int timeout);

}

Constructors

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 glib.MainLoop structure.

Destructor

A destructor is present on this object, but not explicitly documented in the source.

Members

Functions

getContext MainContext getContext(): Returns the glib.MainContext 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 MainLoop.run.
quit void quit(): Stops a glib.MainLoop from running. Any calls to MainLoop.run for the loop will return.
ref_ MainLoop ref_(): Increases the reference count on a glib.MainLoop object by one.
run void run(): Runs a main loop until MainLoop.quit is called on the loop. If this is called for the thread of the loop's glib.MainContext, it will process events from the loop, otherwise it will simply wait.
unref void unref(): Decreases the reference count on a glib.MainLoop object by one. If the result is zero, free the loop and free all associated memory.

Static functions

mainCurrentSource Source mainCurrentSource(): Returns the currently firing source for this thread.
mainDepth int mainDepth(): Returns the depth of the stack of calls to MainContext.dispatch on any glib.MainContext in the current thread. That is, when called from the toplevel, it gives 0. When called from within a callback from MainContext.iteration (or MainLoop.run, etc.) it returns 1. When called from within a callback to a recursive call to MainContext.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 glib.MainContext, 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.
