-- | Binding to the GLIB library for Gtk2Hs.
--   
--   GLib is a collection of C data structures and utility functions for
--   the GObject system, main loop implementation, for strings and common
--   data structures dealing with Unicode. This package only binds as much
--   functionality as required to support the packages that wrap libraries
--   that are themselves based on GLib.
@package glib
@version 0.13.7.0

-- | Attributes interface
--   
--   Attributes of an object can be get and set. Getting the value of an
--   object's attribute is straingtforward. As an example consider a
--   button widget and an attribute called buttonLabel.
--   
--   
--   value <- get button buttonLabel
--   
--   
--   The syntax for setting or updating an attribute is only slightly more
--   complex. At the simplest level it is just:
--   
--   
--   set button [ buttonLabel := value ]
--   
--   
--   However as the list notation would indicate, you can set or update
--   multiple attributes of the same object in one go:
--   
--   
--   set button [ buttonLabel := value, buttonFocusOnClick := False ]
--   
--   
--   You are not limited to setting the value of an attribute, you can also
--   apply an update function to an attribute's value. That is the function
--   receives the current value of the attribute and returns the new value.
--   
--   
--   set spinButton [ spinButtonValue :~ (+1) ]
--   
--   
--   There are other variants of these operators, (see AttrOp).
--   :=> and :~> and like := and :~ but
--   operate in the IO monad rather than being pure. There is also
--   ::= and ::~ which take the object as an extra parameter.
--   
--   Attributes can be read only, write only or both read/write.

-- | Error Reporting, glib's system for reporting errors.
--   
--   GErrors are used by glib to report recoverable runtime errors.
--   
--   This module provides functions for checking glib/gtk functions that
--   report GErrors. It also provides functions for throwing and
--   catching GErrors as Haskell exceptions.
module System.Glib.GError

-- | A GError consists of a domain, code and a human readable message.
data GError
GError :: !GErrorDomain -> !GErrorCode -> !GErrorMessage -> GError

-- | A code used to identify the 'namespace' of the error. Within each
--   error domain all the error codes are defined in an enumeration. Each
--   gtk/gnome module that uses GErrors has its own error domain. The
--   rationale behind using error domains is so that each module can
--   organise its own error codes without having to coordinate on a global
--   error code list.
type GErrorDomain = GQuark

-- | A code to identify a specific error within a given
--   GErrorDomain. Most of time you will not need to deal with this
--   raw code since there is an enumeration type for each error domain. Of
--   course which enumeraton to use depends on the error domain, but if you
--   use catchGErrorJustDomain or handleGErrorJustDomain,
--   this is worked out for you automatically.
type GErrorCode = Int

-- | A human readable error message.
type GErrorMessage = Text

-- | This will catch just a specific GError exception. If you need to catch
--   a range of related errors, catchGErrorJustDomain is probably
--   more appropriate. Example:
--   
--   
--   do image <- catchGErrorJust PixbufErrorCorruptImage
--   loadImage
--   (\errorMessage -> do log errorMessage
--   return mssingImagePlaceholder)
--   
catchGErrorJust :: GErrorClass err => err -> IO a -> (GErrorMessage -> IO a) -> IO a

-- | Catch all GErrors from a particular error domain. The handler function
--   should just deal with one error enumeration type. If you need to catch
--   errors from more than one error domain, use this function twice with
--   an appropriate handler functions for each.
--   
--   
--   catchGErrorJustDomain
--   loadImage
--   (\err message -> case err of
--   PixbufErrorCorruptImage -> ...
--   PixbufErrorInsufficientMemory -> ...
--   PixbufErrorUnknownType -> ...
--   _ -> ...)
--   
catchGErrorJustDomain :: GErrorClass err => IO a -> (err -> GErrorMessage -> IO a) -> IO a

-- | A verson of handleGErrorJust with the arguments swapped around.
handleGErrorJust :: GErrorClass err => err -> (GErrorMessage -> IO a) -> IO a -> IO a

-- | A verson of catchGErrorJustDomain with the arguments swapped
--   around.
handleGErrorJustDomain :: GErrorClass err => (err -> GErrorMessage -> IO a) -> IO a -> IO a

-- | This will catch any GError exception. The handler function will
--   receive the raw GError. This is probably only useful when you want to
--   take some action that does not depend on which GError exception has
--   occured, otherwise it would be better to use either
--   catchGErrorJust or catchGErrorJustDomain. For example:
--   
--   
--   catchGError
--   (do ...
--   ...)
--   (\(GError dom code msg) -> fail msg)
--   

-- | Deprecated: Use ordinary Control.Exception.catch
catchGError :: IO a -> (GError -> IO a) -> IO a

-- | A verson of catchGError with the arguments swapped around.
--   
--   
--   handleGError (\(GError dom code msg) -> ...) $
--   ...
--   

-- | Deprecated: Use ordinary Control.Exception.handle
handleGError :: (GError -> IO a) -> IO a -> IO a

-- | Catch all GError exceptions and convert them into a general failure.
failOnGError :: IO a -> IO a

-- | Use this if you need to explicitly throw a GError or re-throw an
--   existing GError that you do not wish to handle.

-- | Deprecated: Use ordinary Control.Exception.throw
throwGError :: GError -> IO a

-- | Each error domain's error enumeration type should be an instance of
--   this class. This class helps to hide the raw error and domain codes
--   from the user. This interface should be implemented by calling the
--   approrpiate {error_domain}_error_quark. It is safe to use a
--   pure FFI call for this.
--   
--   Example for PixbufError:
--   
--   
--   instance GErrorClass PixbufError where
--   gerrorDomain _ = {#call pure unsafe pixbuf_error_quark#}
--   
class Enum err => GErrorClass err
gerrorDomain :: GErrorClass err => err -> GErrorDomain

-- | Glib functions which report GErrors take as a parameter a
--   GError **error. Use this function to supply such a parameter.
--   It checks if an error was reported and if so throws it as a Haskell
--   exception.
--   
--   Example of use:
--   
--   
--   propagateGError $ \gerrorPtr ->
--   {# call g_some_function_that_might_return_an_error #} a b gerrorPtr
--   
propagateGError :: (Ptr (Ptr ()) -> IO a) -> IO a

-- | Like propagateGError but instead of throwing the GError as an
--   exception handles the error immediately using the supplied error
--   handler.
--   
--   Example of use:
--   
--   
--   checkGError
--   (\gerrorPtr -> {# call g_some_function_that_might_return_an_error #} a b gerrorPtr)
--   (\(GError domain code msg) -> ...)
--
