## Implemented Interfaces

DzlPropertiesGroup implements GActionGroup.

## Description

This class is a GActionGroup which provides stateful access to properties in a GObject. This can be useful when you want to expose properties from a GObject as a GAction, espectially with use in GtkApplications.

Call `dzl_properties_group_add_property()` to setup the mappings for action-name to property-name for the actions you'd like to add.

Not all property types can be supported. What is current supported are properties of type:

`G_TYPE_INT` `G_TYPE_UINT` `G_TYPE_BOOLEAN` `G_TYPE_STRING` `G_TYPE_DOUBLE`

## Functions

### dzl_properties_group_new ()

    DzlPropertiesGroup *
    dzl_properties_group_new (GObject *object);

This creates a new DzlPropertiesGroup to create stateful actions around properties in `object` .

Call `dzl_properties_group_add_property()` to add a property to action name mapping for this group. Until you've called this, no actions are mapped.

Note that DzlPropertiesGroup only holds a weak reference to `object` and therefore you must keep `object` alive elsewhere.

#### Parameters

object | The object containing the properties |

#### Returns

A DzlPropertiesGroup.

### dzl_properties_group_new_for_type ()

    DzlPropertiesGroup *
    dzl_properties_group_new_for_type (GType object_type);

This creates a new DzlPropertiesGroup for which the initial object is `NULL`.

Set `object_type` to a type of a class which is a GObject-based type.

#### Parameters

object_type | A GObjectClass based type |

#### Returns

A DzlPropertiesGroup.

[transfer none]

### dzl_properties_group_add_property ()

    void
    dzl_properties_group_add_property (DzlPropertiesGroup *self,
                                       const gchar *name,
                                       const gchar *property_name);

Adds a new stateful action named `name` which maps to the underlying property `property_name` of “object”.

#### Parameters

self | a DzlPropertiesGroup |
name | the name of the action |
property_name | the name of the property |

Since: 3.26

### dzl_properties_group_add_property_full ()

    void
    dzl_properties_group_add_property_full
                                   (DzlPropertiesGroup *self,
                                    const gchar *name,
                                    const gchar *property_name,
                                    DzlPropertiesFlags flags);

Adds a new stateful action named `name` which maps to the underlying property `property_name` of “object”.

Seting `flags` allows you to tweak some settings about the action.

#### Parameters

self | a DzlPropertiesGroup |
name | the name of the action |
property_name | the name of the property |
flags | optional flags for the action |

Since: 3.26

### dzl_properties_group_add_all_properties ()

    void
    dzl_properties_group_add_all_properties
                                   (DzlPropertiesGroup *self);

This function will try to add all properties found on the target instance to the group. Only properties that are supported by the DzlPropertiesGroup will be added.

The action name of all added properties will be identical to their property name.

#### Parameters

self | A DzlPropertiesGroup |

Since: 3.26

### dzl_properties_group_remove ()

    void
    dzl_properties_group_remove (DzlPropertiesGroup *self,
                                 const gchar *name);

Removes an action from `self` that was previously added with `dzl_properties_group_add_property()`. `name` should match the name parameter to that function.

#### Parameters

self | a DzlPropertiesGroup |
name | the name of the action |

Since: 3.26

## Types and Values

### DZL_TYPE_PROPERTIES_GROUP

    #define DZL_TYPE_PROPERTIES_GROUP (dzl_properties_group_get_type())

### enum DzlPropertiesFlags

#### Members

DZL_PROPERTIES_FLAGS_NONE |  |
DZL_PROPERTIES_FLAGS_STATEFUL_BOOLEANS |  |

### DzlPropertiesGroup

    typedef struct _DzlPropertiesGroup DzlPropertiesGroup;
