void
gtk_cell_editable_start_editing (GtkCellEditable *cell_editable,
                                 GdkEvent *event);

cell_editable

A GtkCellEditable

 

event

A GdkEvent, or NULL.

[allow-none]

gtk_cell_editable_editing_done ()

void
gtk_cell_editable_editing_done (GtkCellEditable *cell_editable);

Emits the “editing-done” signal.

Parameters

cell_editable

A GtkCellEditable

 

gtk_cell_editable_remove_widget ()

void
gtk_cell_editable_remove_widget (GtkCellEditable *cell_editable);

Emits the “remove-widget” signal.

Parameters

cell_editable

A GtkCellEditable

 

Types and Values

GtkCellEditable

typedef struct _GtkCellEditable GtkCellEditable;

struct GtkCellEditableIface

struct GtkCellEditableIface {
  /* signals */
  void (* editing_done)  (GtkCellEditable *cell_editable);
  void (* remove_widget) (GtkCellEditable *cell_editable);

  /* virtual table */
  void (* start_editing) (GtkCellEditable *cell_editable,
			  GdkEvent        *event);
};

Members

editing_done ()

Signal is a sign for the cell renderer to update its value from the cell_editable.

 

remove_widget ()

Signal is meant to indicate that the cell is finished editing, and the widget may now be destroyed.

 

start_editing ()

Begins editing on a cell_editable.

 

Property Details

The “editing-canceled” property

  “editing-canceled”         gboolean

Indicates whether editing on the cell has been canceled.

Flags: Read / Write

Default value: FALSE

Since: 2.20

Signal Details

The “editing-done” signal

void
user_function (GtkCellEditable *cell_editable,
               gpointer         user_data)

This signal is a sign for the cell renderer to update its value from the cell_editable .

Implementations of GtkCellEditable are responsible for emitting this signal when they are done editing, e.g. GtkEntry is emitting it when the user presses Enter.

gtk_cell_editable_editing_done() is a convenience method for emitting “editing-done”.

Parameters

cell_editable

the object on which the signal was emitted

 

user_data

user data set when the signal handler was connected.

The “remove-widget” signal

void
user_function (GtkCellEditable *cell_editable,
               gpointer         user_data)

This signal is meant to indicate that the cell is finished editing, and the widget may now be destroyed.

Implementations of GtkCellEditable are responsible for emitting this signal when they are done editing. It must be emitted after the “editing-done” signal, to give the cell renderer a chance to update the cell's value before the widget is removed.

gtk_cell_editable_remove_widget() is a convenience method for emitting “remove-widget”.

Parameters

cell_editable

the object on which the signal was emitted

 

user_data

user data set when the signal handler was connected.
