Gtk.Bool_Filter

Description

Evaluates a boolean expression to determine whether to include items.

Get_Expression

function Get_Expression
   (Self : not null access Gtk_Bool_Filter_Record)
    return Gtk.Expression.Gtk_Expression

Gets the expression that the filter evaluates for each item.

Parameters

Self

Return Value

the expression. Has transfer-ownership='none'.

Get_Invert

function Get_Invert
   (Self : not null access Gtk_Bool_Filter_Record) return Boolean

Returns whether the filter inverts the expression.

Parameters

Self

Return Value

true if the filter inverts

Get_Type

function Get_Type return Glib.GType

Return Value

Gtk_Bool_Filter

type Gtk_Bool_Filter is access all Gtk_Bool_Filter_Record'Class;

Gtk_Bool_Filter_New

function Gtk_Bool_Filter_New
   (Expression : Gtk.Expression.Gtk_Expression) return Gtk_Bool_Filter

Creates a new bool filter.

Parameters

Expression

the expression to evaluate. Has transfer-ownership='full'.

Return Value

Gtk_Bool_Filter_Record

type Gtk_Bool_Filter_Record is new Gtk_Filter_Record with null record;

Gtk_New

procedure Gtk_New
   (Self       : out Gtk_Bool_Filter;
    Expression : Gtk.Expression.Gtk_Expression)

Creates a new bool filter. Initialize does nothing if the object was already created with another call to Initialize* or G_New.

Parameters

Self

Expression

the expression to evaluate. Has transfer-ownership='full'.

Initialize

procedure Initialize
   (Self       : not null access Gtk_Bool_Filter_Record'Class;
    Expression : Gtk.Expression.Gtk_Expression)

Creates a new bool filter. Initialize does nothing if the object was already created with another call to Initialize* or G_New.

Parameters

Self

Expression

the expression to evaluate. Has transfer-ownership='full'.

Invert_Property

Invert_Property : constant Glib.Properties.Property_Boolean;

If the expression result should be inverted.

Set_Expression

procedure Set_Expression
   (Self       : not null access Gtk_Bool_Filter_Record;
    Expression : Gtk.Expression.Gtk_Expression)

Sets the expression that the filter uses to check if items should be filtered. The expression must have a value type of G_TYPE_BOOLEAN.

Parameters

Self

Expression

the expression

Set_Invert

procedure Set_Invert
   (Self   : not null access Gtk_Bool_Filter_Record;
    Invert : Boolean)

Sets whether the filter should invert the expression.

Parameters

Self

Invert

true to invert
