gtk_source_undo_manager_can_undo ()

gboolean            gtk_source_undo_manager_can_undo    (GtkSourceUndoManager *manager);

Get whether there are undo operations available.

Since 2.10

gtk_source_undo_manager_can_redo ()

gboolean            gtk_source_undo_manager_can_redo    (GtkSourceUndoManager *manager);

Get whether there are redo operations available.

Since 2.10

gtk_source_undo_manager_undo ()

void                gtk_source_undo_manager_undo        (GtkSourceUndoManager *manager);

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

Since 2.10

gtk_source_undo_manager_redo ()

void                gtk_source_undo_manager_redo        (GtkSourceUndoManager *manager);

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

Since 2.10

gtk_source_undo_manager_begin_not_undoable_action ()

void                gtk_source_undo_manager_begin_not_undoable_action
                                                        (GtkSourceUndoManager *manager);

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

Since 2.10

gtk_source_undo_manager_end_not_undoable_action ()

void                gtk_source_undo_manager_end_not_undoable_action
                                                        (GtkSourceUndoManager *manager);

Ends a not undoable action on the buffer.
