                                   GSList *binding_args);

Override or install a new key binding for `keyval` with `modifiers` on `binding_set` .

#### Parameters

binding_set | a GtkBindingSet to add a signal to |
keyval | key value |
modifiers | key modifier |
signal_name | signal name to be bound |
binding_args | list of GtkBindingArg signal arguments. | [transfer none][element-type GtkBindingArg]

### gtk_binding_entry_clear ()

    void
    gtk_binding_entry_clear (GtkBindingSet *binding_set,

                             GdkModifierType modifiers);

`gtk_binding_entry_clear` has been deprecated since version 2.12 and should not be used in newly-written code.

Use `gtk_binding_entry_remove()` instead.

Clears a binding entry.

#### Parameters

binding_set | binding set to clear an entry of |
keyval | key value of binding to clear |
modifiers | key modifier of binding to clear |

### gtk_binding_parse_binding ()

    guint
    gtk_binding_parse_binding (GScanner *scanner);

`gtk_binding_parse_binding` has been deprecated since version 2.12 and should not be used in newly-written code.

There should be no need to call this function outside GTK+.

Parse a binding entry from a gtkrc file.

#### Parameters

scanner | GtkRC scanner |

#### Returns

expected token upon errors, `G_TOKEN_NONE` on success.

### gtk_binding_set_new ()

    GtkBindingSet *
    gtk_binding_set_new (const gchar *set_name);

GTK+ maintains a global list of binding sets. Each binding set has a unique name which needs to be specified upon creation.

#### Parameters

set_name | unique name of this binding set |

#### Returns

new binding set

### gtk_binding_set_by_class ()

    GtkBindingSet *
    gtk_binding_set_by_class (gpointer object_class);

This function returns the binding set named after the type name of the passed in class structure. New binding sets are created on demand by this function.

#### Parameters

object_class | a valid GtkObject class |

#### Returns

the binding set corresponding to `object_class`

### gtk_binding_set_find ()

    GtkBindingSet *
    gtk_binding_set_find (const gchar *set_name);

Find a binding set by its globally unique name. The `set_name` can either be a name used for `gtk_binding_set_new()` or the type name of a class used in `gtk_binding_set_by_class()`.

#### Parameters

set_name | unique binding set name |

#### Returns

`NULL` or the specified binding set.

[transfer none]

Find a key binding matching `keyval` and `modifiers` and activate the binding on `object` .

#### Parameters

object | object to activate when binding found |
keyval | key value of the binding |
modifiers | key modifier of the binding |

#### Returns

`TRUE` if a binding was found and activated

    gtk_bindings_activate_event (GtkObject *object,
                                 GdkEventKey *event);

Looks up key bindings for `object` to find one matching `event` , and if one was found, activate it.

                                  ...);

Override or install a new key binding for `keyval` with `modifiers` on `binding_set` . When the binding is activated, `signal_name` will be emitted on the target widget, with `n_args` `Varargs` used as arguments.

#### Parameters
