Signals


"editing-done"
            void        user_function      (GtkCellEditable *celleditable,
                                            gpointer         user_data)         : Run last
"remove-widget"
            void        user_function      (GtkCellEditable *celleditable,
                                            gpointer         user_data)         : Run last

Description

The GtkCellEditable interface must be implemented for widgets to be usable when editing the contents of a GtkTreeView cell.

Details

GtkCellEditable

typedef struct _GtkCellEditable GtkCellEditable;

GtkCellEditableIface

typedef struct {
  GTypeInterface g_iface;

  /* signals */
  void (* editing_done)  (GtkCellEditable *cell_editable);
  void (* remove_widget) (GtkCellEditable *cell_editable);

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

gtk_cell_editable_start_editing ()

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

Begins editing on a cell_editable. event is the GdkEvent that began the editing process. It may be NULL, in the instance that editing was initiated through programatic means.

cell_editable : A GtkCellEditable
event : A GdkEvent, or NULL

gtk_cell_editable_editing_done ()

void        gtk_cell_editable_editing_done  (GtkCellEditable *cell_editable);

Emits the "editing_done" signal. This signal is a sign for the cell renderer to update its value from the cell.

cell_editable : A GtkTreeEditable

gtk_cell_editable_remove_widget ()

void        gtk_cell_editable_remove_widget (GtkCellEditable *cell_editable);

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

cell_editable : A GtkTreeEditable

Signal Details

The "editing-done" signal

void        user_function                  (GtkCellEditable *celleditable,
                                            gpointer         user_data)         : Run last

celleditable : the object which received the signal.
user_data : user data set when the signal handler was connected.

The "remove-widget" signal

void        user_function                  (GtkCellEditable *celleditable,
                                            gpointer         user_data)         : Run last

celleditable : the object which received the signal.
user_data : user data set when the signal handler was connected.
