procedure Install_Property
(Class_Record : Glib.Object.GObject_Class;
Prop_Id : Property_Id;
Property_Spec : Param_Spec)
Adds a new property to Class_Record. You should use this function only on class records you have created yourself, not on one of the standard widgets. Prop_Id is the internal representation for properties, that will be passed to the Set_Property and Get_Property_Handlers (see above) to set and retrieve the value of a property. Property_Spec should be the result of one of the GNew_* subprograms for Param_Spec, and this defines the type of the property.
You must have called Set_Properties_Handler first.

function Name (Val : Enum_Value) return String
Return the name of Val. This is the equivalent of 'Image in Ada.
function Name (Val : Flags_Value) return String
Return the name of Val. This is the equivalent of 'Image in Ada.
function Nick (Val : Enum_Value) return String
Return a displayable string for Val.
function Nick (Val : Flags_Value) return String
Return a displayable string for Val.
function Nick_Name (Param : Param_Spec) return String
Return the nickname of the property. This is a string that can be displayed to represent the property, and is more user-friendly than the result of Name.
function Nth_Value (Klass : Enum_Class; Nth : Glib.Guint) return Enum_Value
Return the Nth-th value in Klass, or null if there is no such value.
function Nth_Value (Klass : Flags_Class; Nth : Glib.Guint)
return Flags_Value
Return the Nth-th value in Klass, or null if there is no such value.
procedure Override_Property
(Class_Record : Glib.Object.GObject_Class;
Prop_Id : Property_Id;
Name : String)
Overrides an existing property (inherited from the parent type or from one of the interfaces that are implemented). You must have called Set_Properties_Handler first.
function Owner_Type (Param : Param_Spec) return Glib.GType
The type that defined Param. If you look for instance at all properties provides by a type, they will also include properties provided by the parents of the type. This function can be used to find those declared with that type only

function Pspec_Name (Param : Param_Spec) return String
Return the name of the property. This is the internal string representing the property. It Should probably not be displayed on
function Register_Static_Enum
(Name : String;
Values : Gtkada.Types.Chars_Ptr_Array) return Glib.GType
Create a new enumeration class from a list of valid values. Values must be freed by the caller.
procedure Set_Properties_Handlers
(Class_Record : Glib.Object.GObject_Class;
Set_Property : not null Set_Property_Handler;
Get_Property : not null Get_Property_Handler)
Set the two functions used to set and retrieve properties. You should never call this function on the class record of the standard gtk+ widgets, since this will break their behavior. You should first create a new class record through Initialize_Class_Record, and then use the returned Class_Record as a parameter to this subprogram.
You cannot pass null to either of the two parameters, or you won't be able to install new properties afterwards
type Set_Property_Handler is access procedure
(Object : access Glib.Object.GObject_Record'Class;
Prop_Id : Property_Id;
Value : Glib.Values.GValue;
Property_Spec : Param_Spec);
This handler is called every time the user has asked for a new property to be changed. Prop_Id is the id you used when creating the property. Value is the new value that should be set. It is your responsability to extract the actual value from it. However, consistency has already been checked by gtk+, so we know the type is correct. Property_Spec is the definition of the property.
Note: It is your responsability to emit the "notify" signal after a property has been modified. The recommended way is to emit this signal from the internal function that actually modified the property, not directly from the Set_Propert_Handler itself. This will ensure that even if the user doesn't modify the attribute through a property but directly by calling the lower-level subprogram, the signal will still be emitted.
procedure Set_Qdata
(Param : Param_Spec;
Quark : GQuark;
Data : Glib.C_Proxy;
Destroy : G_Destroy_Notify := null)
Associate some named data with Param. Destroy is called when Param is destroyed.
procedure Set_Value_Type (Param : Param_Spec; Typ : Glib.GType)
Override the type of param. You should only use this function when creating new Param_Spec types based on existing types. You should not change the type if you haven't created param yourself.
function Substitutor (Param : Param_Spec_String) return Character
procedure Unref (Param : Param_Spec)
Decrement the reference counter. If it reaches 0, the memory is freed.
function Value (Val : Enum_Value) return Glib.Gint
Return the numeric value for a specific enumeration. Use the matching Ada type and 'Val to convert it to a valid Ada enumeration
function Value (Val : Flags_Value) return Flags_Int_Value
Return the numeric value for a specific enumeration. Use the matching Ada type and 'Val to convert it to a valid Ada enumeration
function Value_Type (Param : Param_Spec) return Glib.GType
