class GObject o => IsUndoManager o

Instances

(GObject a, UnknownAncestorError Constraint UndoManager a) => IsUndoManager a

IsUndoManager UndoManager

toUndoManager :: (MonadIO m, IsUndoManager o) => o -> m UndoManager

Methods

beginNotUndoableAction

undoManagerBeginNotUndoableAction

Arguments

:: (HasCallStack, MonadIO m, IsUndoManager a)

=> a

manager: a UndoManager.

-> m ()

Begin a not undoable action on the buffer. All changes between this call and the call to undoManagerEndNotUndoableAction cannot be undone. This function should be re-entrant.

Since: 2.10

canRedo

undoManagerCanRedo

Arguments

:: (HasCallStack, MonadIO m, IsUndoManager a)

=> a

manager: a UndoManager.

-> m Bool

Returns: True if there are redo operations available, False otherwise

Get whether there are redo operations available.

Since: 2.10

canRedoChanged

undoManagerCanRedoChanged

Arguments

:: (HasCallStack, MonadIO m, IsUndoManager a)

=> a

manager: a UndoManager.

-> m ()

Emits the UndoManager::can-redo-changed signal.

Since: 2.10

canUndo

undoManagerCanUndo

Arguments

:: (HasCallStack, MonadIO m, IsUndoManager a)

=> a

manager: a UndoManager.

-> m Bool

Returns: True if there are undo operations available, False otherwise

Get whether there are undo operations available.

Since: 2.10

canUndoChanged

undoManagerCanUndoChanged

Arguments

:: (HasCallStack, MonadIO m, IsUndoManager a)

=> a

manager: a UndoManager.

-> m ()

Emits the UndoManager::can-undo-changed signal.

Since: 2.10

endNotUndoableAction

undoManagerEndNotUndoableAction

Arguments

:: (HasCallStack, MonadIO m, IsUndoManager a)

=> a

manager: a UndoManager.

-> m ()

Ends a not undoable action on the buffer.

Since: 2.10

redo

undoManagerRedo

Arguments

:: (HasCallStack, MonadIO m, IsUndoManager a)

=> a

manager: a UndoManager.

-> m ()

Perform a single redo. Calling this function when there are no redo operations available is an error. Use undoManagerCanRedo to find out if there are redo operations available.

Since: 2.10

undo

undoManagerUndo

Arguments

:: (HasCallStack, MonadIO m, IsUndoManager a)

=> a

manager: a UndoManager.

-> m ()

Perform a single undo. Calling this function when there are no undo operations available is an error. Use undoManagerCanUndo to find out if there are undo operations available.

Since: 2.10
