ClientTypeHandler

type C_ClientTypeHandler = Ptr Menuitem -> Ptr Menuitem -> Ptr Client -> Ptr () -> IO CInt Source #

Type for the callback on the (unwrapped) C side.

type ClientTypeHandler Source #

Arguments

= Menuitem	`newitem`: The `Menuitem` that was created
-> Menuitem	`parent`: The parent of `newitem` or `NULL` if none
-> Client	`client`: A pointer to the `Client`
-> IO Bool

The type handler is called when a dbusmenu item is created with a matching type as setup in dbusmenu_client_add_type_handler

Return value: TRUE if the type has been handled. FALSE if this function was somehow unable to handle it.

type ClientTypeHandler_WithClosures Source #

Arguments

= Menuitem	`newitem`: The `Menuitem` that was created
-> Menuitem	`parent`: The parent of `newitem` or `NULL` if none
-> Client	`client`: A pointer to the `Client`
-> Ptr ()	`userData`: The data you gave us
-> IO Bool

The type handler is called when a dbusmenu item is created with a matching type as setup in dbusmenu_client_add_type_handler

Return value: TRUE if the type has been handled. FALSE if this function was somehow unable to handle it.

drop_closures_ClientTypeHandler :: ClientTypeHandler -> ClientTypeHandler_WithClosures Source #

A simple wrapper that ignores the closure arguments.

dynamic_ClientTypeHandler Source #

Arguments

:: (HasCallStack, MonadIO m, IsMenuitem a, IsMenuitem b, IsClient c)
=> FunPtr C_ClientTypeHandler
-> a	`newitem`: The `Menuitem` that was created
-> b	`parent`: The parent of `newitem` or `NULL` if none
-> c	`client`: A pointer to the `Client`
-> Ptr ()	`userData`: The data you gave us
-> m Bool

Given a pointer to a foreign C function, wrap it into a function callable from Haskell.

genClosure_ClientTypeHandler :: ClientTypeHandler -> IO Closure Source #

Wrap the callback into a Closure.

mk_ClientTypeHandler :: C_ClientTypeHandler -> IO (FunPtr C_ClientTypeHandler) Source #

Generate a function pointer callable from C code, from a C_ClientTypeHandler.

noClientTypeHandler :: Maybe ClientTypeHandler Source #

A convenience synonym for Nothing :: Maybe ClientTypeHandler.

noClientTypeHandler_WithClosures :: Maybe ClientTypeHandler_WithClosures Source #

A convenience synonym for Nothing :: Maybe ClientTypeHandler_WithClosures.

wrap_ClientTypeHandler :: Maybe (Ptr (FunPtr C_ClientTypeHandler)) -> ClientTypeHandler_WithClosures -> C_ClientTypeHandler Source #

Wrap a ClientTypeHandler into a C_ClientTypeHandler.

MenuitemAboutToShowCb

type C_MenuitemAboutToShowCb = Ptr Menuitem -> Ptr () -> IO () Source #

Type for the callback on the (unwrapped) C side.

type MenuitemAboutToShowCb Source #

Arguments

= Menuitem	`mi`: Menu item that should be shown
-> IO ()

Callback prototype for a callback that is called when the menu should be shown.

type MenuitemAboutToShowCb_WithClosures Source #

Arguments

= Menuitem	`mi`: Menu item that should be shown
-> Ptr ()	`userData`: Extra user data sent with the function
-> IO ()

Callback prototype for a callback that is called when the menu should be shown.

drop_closures_MenuitemAboutToShowCb :: MenuitemAboutToShowCb -> MenuitemAboutToShowCb_WithClosures Source #

A simple wrapper that ignores the closure arguments.

dynamic_MenuitemAboutToShowCb Source #

Arguments

:: (HasCallStack, MonadIO m, IsMenuitem a)
=> FunPtr C_MenuitemAboutToShowCb
-> a	`mi`: Menu item that should be shown
-> Ptr ()	`userData`: Extra user data sent with the function
-> m ()

Given a pointer to a foreign C function, wrap it into a function callable from Haskell.

genClosure_MenuitemAboutToShowCb :: MenuitemAboutToShowCb -> IO Closure Source #

Wrap the callback into a Closure.

mk_MenuitemAboutToShowCb :: C_MenuitemAboutToShowCb -> IO (FunPtr C_MenuitemAboutToShowCb) Source #

Generate a function pointer callable from C code, from a C_MenuitemAboutToShowCb.

noMenuitemAboutToShowCb :: Maybe MenuitemAboutToShowCb Source #

A convenience synonym for Nothing :: Maybe MenuitemAboutToShowCb.

noMenuitemAboutToShowCb_WithClosures :: Maybe MenuitemAboutToShowCb_WithClosures Source #

A convenience synonym for Nothing :: Maybe MenuitemAboutToShowCb_WithClosures.

wrap_MenuitemAboutToShowCb :: Maybe (Ptr (FunPtr C_MenuitemAboutToShowCb)) -> MenuitemAboutToShowCb_WithClosures -> C_MenuitemAboutToShowCb Source #

-> Maybe Text	`properties`: A list of properties that should be the only ones in the resulting variant structure
-> IO GVariant	Returns: A variant representing this item and its children
