Signals

SelectionFunc

type C_SelectionFunc = Ptr Terminal -> CLong -> CLong -> Ptr () -> IO CInt Source #

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

type SelectionFunc Source #

Arguments

= Terminal	`terminal`: terminal in which the cell is.
-> CLong	`column`: column in which the cell is.
-> CLong	`row`: row in which the cell is.
-> IO Bool	Returns: `True` if cell has to be selected; `False` if otherwise.

Specifies the type of a selection function used to check whether a cell has to be selected or not.

type SelectionFunc_WithClosures Source #

Arguments

= Terminal	`terminal`: terminal in which the cell is.
-> CLong	`column`: column in which the cell is.
-> CLong	`row`: row in which the cell is.
-> Ptr ()	`data`: user data.
-> IO Bool	Returns: `True` if cell has to be selected; `False` if otherwise.

Specifies the type of a selection function used to check whether a cell has to be selected or not.

drop_closures_SelectionFunc :: SelectionFunc -> SelectionFunc_WithClosures Source #

A simple wrapper that ignores the closure arguments.

dynamic_SelectionFunc Source #

Arguments

:: (HasCallStack, MonadIO m, IsTerminal a)
=> FunPtr C_SelectionFunc
-> a	`terminal`: terminal in which the cell is.
-> CLong	`column`: column in which the cell is.
-> CLong	`row`: row in which the cell is.
-> Ptr ()	`data`: user data.
-> m Bool	Returns: `True` if cell has to be selected; `False` if otherwise.

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

genClosure_SelectionFunc :: MonadIO m => SelectionFunc -> m (GClosure C_SelectionFunc) Source #

Wrap the callback into a GClosure.

mk_SelectionFunc :: C_SelectionFunc -> IO (FunPtr C_SelectionFunc) Source #

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

noSelectionFunc :: Maybe SelectionFunc Source #

A convenience synonym for Nothing :: Maybe SelectionFunc.

noSelectionFunc_WithClosures :: Maybe SelectionFunc_WithClosures Source #

A convenience synonym for Nothing :: Maybe SelectionFunc_WithClosures.

wrap_SelectionFunc :: Maybe (Ptr (FunPtr C_SelectionFunc)) -> SelectionFunc_WithClosures -> C_SelectionFunc Source #

Wrap a SelectionFunc into a C_SelectionFunc.

TerminalSpawnAsyncCallback

type C_TerminalSpawnAsyncCallback = Ptr Terminal -> Int32 -> Ptr GError -> Ptr () -> IO () Source #

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

type TerminalSpawnAsyncCallback Source #

Arguments

= Terminal	`terminal`: the `Terminal`
-> Int32	`pid`: a `GPid`
-> GError	`error`: a `GError`, or `Nothing`
-> IO ()

Callback for terminalSpawnAsync.

On success, pid contains the PID of the spawned process, and error is Nothing. On failure, pid is -1 and error contains the error information.

Since: 0.48

type TerminalSpawnAsyncCallback_WithClosures Source #

Arguments

= Terminal	`terminal`: the `Terminal`
-> Int32	`pid`: a `GPid`
-> GError	`error`: a `GError`, or `Nothing`
-> Ptr ()	`userData`: user data that was passed to vte_terminal_spawn_async
-> IO ()

Callback for terminalSpawnAsync.

On success, pid contains the PID of the spawned process, and error is Nothing. On failure, pid is -1 and error contains the error information.

Since: 0.48

drop_closures_TerminalSpawnAsyncCallback :: TerminalSpawnAsyncCallback -> TerminalSpawnAsyncCallback_WithClosures Source #

A simple wrapper that ignores the closure arguments.

dynamic_TerminalSpawnAsyncCallback Source #

Arguments

=> FunPtr C_TerminalSpawnAsyncCallback
-> a	`terminal`: the `Terminal`
-> Int32	`pid`: a `GPid`
-> GError	`error`: a `GError`, or `Nothing`
-> Ptr ()	`userData`: user data that was passed to vte_terminal_spawn_async
-> m ()

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

genClosure_TerminalSpawnAsyncCallback :: MonadIO m => TerminalSpawnAsyncCallback -> m (GClosure C_TerminalSpawnAsyncCallback) Source #

Wrap the callback into a GClosure.

mk_TerminalSpawnAsyncCallback :: C_TerminalSpawnAsyncCallback -> IO (FunPtr C_TerminalSpawnAsyncCallback) Source #

noTerminalSpawnAsyncCallback :: Maybe TerminalSpawnAsyncCallback Source #

A convenience synonym for Nothing :: Maybe TerminalSpawnAsyncCallback.

noTerminalSpawnAsyncCallback_WithClosures :: Maybe TerminalSpawnAsyncCallback_WithClosures Source #

A convenience synonym for Nothing :: Maybe TerminalSpawnAsyncCallback_WithClosures.

wrap_TerminalSpawnAsyncCallback :: Maybe (Ptr (FunPtr C_TerminalSpawnAsyncCallback)) -> TerminalSpawnAsyncCallback_WithClosures -> C_TerminalSpawnAsyncCallback Source #

Wrap a TerminalSpawnAsyncCallback into a C_TerminalSpawnAsyncCallback.
