The GtkSourceUndoManager interface can be implemented to provide custom
undo management to a GtkSourceBuffer. Use
gtk_source_buffer_set_undo_manager() to install a custom undo manager for
a particular source buffer.
Use gtk_source_undo_manager_can_undo_changed() and
gtk_source_undo_manager_can_redo_changed() when respectively the undo state
or redo state of the undo stack has changed.
gboolean gtk_source_undo_manager_can_undo (GtkSourceUndoManager *manager);
Get whether there are undo operations available.
|
a GtkSourceUndoManager. |
Returns : |
TRUE if there are undo operations available, FALSE otherwise |
Since 2.10
gboolean gtk_source_undo_manager_can_redo (GtkSourceUndoManager *manager);
Get whether there are redo operations available.
|
a GtkSourceUndoManager. |
Returns : |
TRUE if there are redo operations available, FALSE otherwise |
Since 2.10
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.
|
a GtkSourceUndoManager. |
Since 2.10
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.
|
a GtkSourceUndoManager. |
Since 2.10
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.
|
a GtkSourceUndoManager. |
Since 2.10
void gtk_source_undo_manager_end_not_undoable_action
(GtkSourceUndoManager *manager);
Ends a not undoable action on the buffer.
|
a GtkSourceUndoManager. |
Since 2.10
void gtk_source_undo_manager_can_undo_changed
(GtkSourceUndoManager *manager);
Emits the "can-undo-changed" signal.
|
a GtkSourceUndoManager. |
Since 2.10
void gtk_source_undo_manager_can_redo_changed
(GtkSourceUndoManager *manager);
Emits the "can-redo-changed" signal.
|

Since 2.10
"can-redo-changed" signalvoid user_function (GtkSourceUndoManager *manager,
gpointer user_data) : Action
Emitted when the ability to redo has changed.
|
The GtkSourceUndoManager |
|
user data set when the signal handler was connected. |
Since 2.10
