## Description

TeplSettingsBindingGroup is a small utility to call `g_settings_unbind()` on a group of properties (on the same GObject).

The documentation of `g_settings_unbind()` says that bindings are automatically removed when the object is finalized. The purpose of TeplSettingsBindingGroup is to unbind the settings in ``dispose()`` instead. Setting a property while an object has already been disposed but not finalized is usually not well tested, and can result to crashes, so it is more robust to unbind the settings in ``dispose()``.

To achieve the same, you can also write a list of `g_settings_unbind()` calls at the appropriate place. But where `g_settings_bind()` (or similar) and `g_settings_unbind()` need to be called are at different places so it is more error-prone to maintain. With this utility, `tepl_settings_binding_group_add()` is called at the same place as `g_settings_bind()`.

## Functions

### tepl_settings_binding_group_new ()

    TeplSettingsBindingGroup *
    tepl_settings_binding_group_new (void);

[skip]

#### Returns

a new TeplSettingsBindingGroup instance.

[transfer full]

Since: 6.11

### tepl_settings_binding_group_free ()

    void
    tepl_settings_binding_group_free (TeplSettingsBindingGroup *group);

Frees a TeplSettingsBindingGroup instance.

[skip]

#### Parameters

group | a TeplSettingsBindingGroup. | [nullable]

Since: 6.11

### tepl_settings_binding_group_add ()

    void
    tepl_settings_binding_group_add (TeplSettingsBindingGroup *group,
                                     const gchar *property_name);

Adds `property_name` to `group` .

Each time that you call `g_settings_bind()` (or similar), you should call this function too.

#### Parameters

group | a TeplSettingsBindingGroup. |
property_name | the name of a GObject property. |

Since: 6.11

### tepl_settings_binding_group_unbind ()

    void
    tepl_settings_binding_group_unbind (TeplSettingsBindingGroup *group,
                                        GObject *object);

Calls `g_settings_unbind()` on `object` for all properties that have been added to `group` .

This function is intended to be called in ``dispose()``.

#### Parameters

group | a TeplSettingsBindingGroup. |
object | a GObject. |

Since: 6.11

## Types and Values

### TeplSettingsBindingGroup

    typedef struct _TeplSettingsBindingGroup TeplSettingsBindingGroup;
