gtk_cell_editable_start_editing ()

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

Begins editing on a cell_editable .

The GtkCellRenderer for the cell creates and returns a GtkCellEditable from gtk_cell_renderer_start_editing(), configured for the GtkCellRenderer type.

gtk_cell_editable_start_editing() can then set up cell_editable suitably for editing a cell, e.g. making the Esc key emit “editing-done”.

Note that the cell_editable is created on-demand for the current edit; its lifetime is temporary and does not persist across other edits and/or cells.

gtk_cell_editable_editing_done ()

void
gtk_cell_editable_editing_done (GtkCellEditable *cell_editable);

Emits the “editing-done” signal.

gtk_cell_editable_remove_widget ()

void
gtk_cell_editable_remove_widget (GtkCellEditable *cell_editable);

Emits the “remove-widget” signal.

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);
};

The “editing-canceled” property

  “editing-canceled”         gboolean

Indicates whether editing on the cell has been canceled.

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 emits this signal when the user presses Enter. Typical things to do in a handler for ::editing-done are to capture the edited value, disconnect the cell_editable from signals on the GtkCellRenderer, etc.

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

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 cell_editable widget is being removed and may subsequently 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”.
