Member Function Documentation

◆ create() [1/3]

template <class T >
template <class OT >
static Glib::RefPtr<PropertyExpression> Gtk::PropertyExpression< T >::create ( const Glib::RefPtr< OT > &  expression,
const Glib::ustring &  property_name 
)
static

Creates an expression that looks up a property via the given expression.

If the resulting object conforms to OT, its property named property_name will be queried. Otherwise, this expression's evaluation will fail.

The value type of the given expression must have a property with property_name.

Parameters
expressionExpression to evaluate to get the object to query.
property_nameName of the property.
Returns
A new Gtk::Expression.

◆ create() [2/3]

template <class T >
template <class OT >
static Glib::RefPtr<PropertyExpression> Gtk::PropertyExpression< T >::create ( GType  this_type,
const Glib::RefPtr< OT > &  expression,
const Glib::ustring &  property_name 
)
static

Creates an expression that looks up a property via the given expression.

If the resulting object conforms to this_type, its property named property_name will be queried. Otherwise, this expression's evaluation will fail.

The given this_type must have a property with property_name.

Parameters
this_typeThe type to expect for the this type.
expressionExpression to evaluate to get the object to query.
property_nameName of the property.
Returns
A new Gtk::Expression.

◆ create() [3/3]

template <class T >
static Glib::RefPtr<PropertyExpression> Gtk::PropertyExpression< T >::create ( GType  this_type,
const Glib::ustring &  property_name 
)
static

Creates an expression that looks up a property via the this argument.

If the resulting object conforms to this_type, its property named property_name will be queried. Otherwise, this expression's evaluation will fail.

The given this_type must have a property with property_name.

Parameters
this_typeThe type to expect for the this type.
property_nameName of the property.
Returns
A new Gtk::Expression.

◆ get_type()

template <class T >
static GType Gtk::PropertyExpression< T >::get_type ( )
static

Get the GType for this class, for use with the underlying GObject type system.
