GObject.ObjectClass.install_property
Description: Reference for GObject.ObjectClass.install_property

### Class method

# GObject ObjectClassinstall_property

#### Declaration [src]

    void
    g_object_class_install_property (
      GObjectClass* oclass,
      guint property_id,
      GParamSpec* pspec
    )

#### Description [src]

Installs a new property.

All properties should be installed during the class initializer. It is possible to install properties after that, but doing so is not recommend, and specifically, is not guaranteed to be thread-safe vs. use of properties on the same type on other threads.

Note that it is possible to redefine a property in a derived class, by installing a property with the same name. This can be useful at times, e.g. to change the range of allowed values or the default value.

#### Parameters

`property_id`

  Type: `guint`

  The id for the new property.

`pspec`

  Type: `GParamSpec`

  The `GParamSpec` for the new property.

  The data is owned by the caller of the method.
