SelectionFunc

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

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

type SelectionFunc

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

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

A simple wrapper that ignores the closure arguments.

dynamic_SelectionFunc

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 :: SelectionFunc -> IO Closure

Wrap the callback into a Closure.

mk_SelectionFunc :: C_SelectionFunc -> IO (FunPtr C_SelectionFunc)

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

noSelectionFunc :: Maybe SelectionFunc

A convenience synonym for Nothing :: Maybe SelectionFunc.

noSelectionFunc_WithClosures :: Maybe SelectionFunc_WithClosures

A convenience synonym for Nothing :: Maybe SelectionFunc_WithClosures.

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

Wrap a SelectionFunc into a C_SelectionFunc.

TerminalSpawnAsyncCallback

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

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

type TerminalSpawnAsyncCallback

Arguments

 = Terminal

terminal: the Terminal

-> Int32

pid: a GPid

-> GError

error: a GError, or Nothing

-> IO ()

Callback for vte_terminal_spawn_async().

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

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 vte_terminal_spawn_async().

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

A simple wrapper that ignores the closure arguments.

dynamic_TerminalSpawnAsyncCallback

Arguments

:: (HasCallStack, MonadIO m, IsTerminal a)

=> 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 :: TerminalSpawnAsyncCallback -> IO Closure

Wrap the callback into a Closure.

mk_TerminalSpawnAsyncCallback :: C_TerminalSpawnAsyncCallback -> IO (FunPtr C_TerminalSpawnAsyncCallback)

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

noTerminalSpawnAsyncCallback :: Maybe TerminalSpawnAsyncCallback

A convenience synonym for Nothing :: Maybe TerminalSpawnAsyncCallback.

noTerminalSpawnAsyncCallback_WithClosures :: Maybe TerminalSpawnAsyncCallback_WithClosures

A convenience synonym for Nothing :: Maybe TerminalSpawnAsyncCallback_WithClosures.

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

Wrap a TerminalSpawnAsyncCallback into a C_TerminalSpawnAsyncCallback.
