Detailed Description

Build an interface from an XML UI definition description.

This object represents an ‘instantiation’ of an UI definition description. When one of these objects is created, the XML file is read, and the user interface is created. The Gtk::Builder object then provides an interface for accessing the widgets in the user interface by the names assigned to them inside the UI description.

A Gtk::Builder holds a reference to all objects that it has constructed and drops these references when it is deleted. This deletion can cause the destruction of non-widget objects or widgets which are not contained in a toplevel window. For toplevel windows constructed by a builder, it is the responsibility of the user to get them with get_widget() or get_widget_derived() and delete them to get rid of them and all the widgets they contain.

The methods get_widget() and get_widget_derived() can be used to access the widgets in the interface by the names assigned to them inside the UI description. Toplevel windows returned by these methods will stay around until the user explicitly deletes them. Other widgets will either be part of a larger hierarchy constructed by the builder (in which case you should not have to worry about their lifecycle), or without a parent, in which case they have to be added to some container before the builder is deleted to make use of them. Non-widget objects need to be fetched with get_object() or get_objects() to keep them beyond the lifespan of the builder.

Gtk::Builder and Glib::Property: A derived widget that contains Glib::Property members must be registered with its own name in the GType system. It must be registered before any of the create_from_*() or add_from_*() methods are called, meaning that you may have to create an instance of your derived widget just to have its class registered. There is no reasonably easy way to combine Gtk::Builder with non-widget objects containing Glib::Property members. Combining it with widgets containing Glib::Property members requires glibmm 2.62 or newer. See also get_widget_derived() and Glib::Property.

std::vector< Glib::RefPtr< Glib::Object > > Gtk::Builder::get_objects ( )

Gets all objects that have been constructed by the Gtk::Builder.

Since gtkmm 3.8:

Returns: A vector containing all the objects constructed by the Gtk::Builder instance.

◆ get_objects() [2/2]

std::vector< Glib::RefPtr< const Glib::Object > > Gtk::Builder::get_objects ( ) const

Gets all objects that have been constructed by the Gtk::Builder.

Since gtkmm 3.8:

Returns: A vector containing all the objects constructed by the Gtk::Builder instance.

◆ get_translation_domain()

Glib::ustring Gtk::Builder::get_translation_domain ( ) const

Gets the translation domain of builder.

Since gtkmm 2.12:

Returns: The translation domain. This string is owned by the builder object and must not be modified or freed.

◆ get_type()

static GType Gtk::Builder::get_type ( )

static

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

◆ get_widget() [1/2]

template <class T_Widget >

void Gtk::Builder::get_widget	(	const Glib::ustring &	name,
		const T_Widget *&	widget
	)		const

inline

See the non-const version.

Since gtkmm 3.8:

◆ get_widget() [2/2]

template <class T_Widget >

void Gtk::Builder::get_widget	(	const Glib::ustring &	name,
		T_Widget *&	widget
	)

inline

Gets a widget from the Builder file.

For instance:

Gtk::Grid* pGrid = nullptr;

refBuilder->get_widget("mygrid", pGrid);

Gtk::Grid

A container which arranges its child widgets in rows and columns.

Definition: grid.h:69

This method prints a warning message to the console if the widget doesn't exist or has the wrong type, so you don't need to check that manually.

Note that you are responsible for deleting top-level widgets (windows and dialogs) instantiated by the Builder object. Other widgets are instantiated as managed so they will be deleted automatically if you add them to a container widget.

Parameters

	name	The name of the widget.
[out]	widget	A pointer to the widget, or `nullptr` on failure.

◆ get_widget_checked()

Gtk::Widget * Gtk::Builder::get_widget_checked	(	const Glib::ustring &	name,
		GType	type
	)

protected

◆ get_widget_derived() [1/2]

template <typename T_Widget , typename... Args>

void Gtk::Builder::get_widget_derived	(	const Glib::ustring &	name,
		const T_Widget *&	widget,
		Args &&...	args
	)		const

inline

See the non-const version.

Since gtkmm 3.8:

◆ get_widget_derived() [2/2]

template <typename T_Widget , typename... Args>

void Gtk::Builder::get_widget_derived	(	const Glib::ustring &	name,
		T_Widget *&	widget,
		Args &&...	args
	)

inline

Gets a widget whose details are specified in the GtkBuilder file, but which is implemented by your own derived class.

Your class must have a constructor like so:

MyDerivedDialog::MyDerivedDialog(BaseObjectType* cobject, const Glib::RefPtr<Gtk::Builder>& refBuilder)

: Gtk::Dialog(cobject) //Calls the base class constructor

Gtk::Dialog

Create popup windows.

Definition: dialog.h:246

Gtk

Definition: accelkey.h:31

or, with additional parameters, for example:

MyDerivedDialog::MyDerivedDialog(BaseObjectType* cobject, const Glib::RefPtr<Gtk::Builder>& refBuilder,
  const Glib::ustring& msg, bool warning)
: Gtk::Dialog(cobject) //Calls the base class constructor

For instance:

MyDerivedDialog* pDialog1 = nullptr;
MyDerivedDialog* pDialog2 = nullptr;
refBuilder->get_widget_derived("mydialog1", pDialog1);
refBuilder->get_widget_derived("mydialog2", pDialog2, "A storm is imminent!", true);

Note: If get_widget_derived() is called more than once for the same widget (the same name), only the first call will call the widget's constructor. The following calls will return a pointer to the widget instance that was constructed by the first call.

Gtk::Builder and Glib::Property: If the widget contains Glib::Property members, your constructor must call the Glib::ObjectBase constructor with a new GType name:
MyDerivedDialog::MyDerivedDialog(BaseObjectType* cobject, const Glib::RefPtr<Gtk::Builder>& refBuilder)

: Glib::ObjectBase("MyDialog"), // The GType name will be gtkmm__CustomObject_MyDialog

Gtk::Dialog(cobject) // Calls the base class constructor

m_my_property(*this, "my-property")

Glib
Definition: applaunchcontext.h:210

Parameters

	name	The name of the widget.
	args	Additional arguments to pass to the constructor of the derived class.
[out]	widget	A pointer to the widget, or `nullptr` on failure.

◆ gobj() [1/2]

GtkBuilder * Gtk::Builder::gobj ( )

inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GtkBuilder * Gtk::Builder::gobj ( ) const

inline

Provides access to the underlying C GObject.

◆ gobj_copy()

GtkBuilder * Gtk::Builder::gobj_copy ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

◆ operator=()

Builder & Gtk::Builder::operator= ( Builder && src )

noexcept

◆ property_translation_domain() [1/2]

Glib::PropertyProxy< Glib::ustring > Gtk::Builder::property_translation_domain ( )

The translation domain used when translating property values that have been marked as translatable in interface descriptions.

If the translation domain is nullptr, Gtk::Builder uses gettext(), otherwise Glib::dgettext().

Since gtkmm 2.12:

Default value: ""

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_translation_domain() [2/2]

Glib::PropertyProxy_ReadOnly< Glib::ustring > Gtk::Builder::property_translation_domain ( ) const

The translation domain used when translating property values that have been marked as translatable in interface descriptions.

If the translation domain is nullptr, Gtk::Builder uses gettext(), otherwise Glib::dgettext().

Since gtkmm 2.12:

Default value: ""

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ set_application()

void Gtk::Builder::set_application ( const Glib::RefPtr< Application > & application )

Sets the application associated with builder.

You only need this function if there is more than one Gio::Application in your process. application cannot be nullptr.

Since gtkmm 3.10:

Parameters

application A Gtk::Application.

◆ set_translation_domain()

void Gtk::Builder::set_translation_domain ( const Glib::ustring & domain )

Sets the translation domain of builder.

See Gtk::Builder::property_translation_domain().

Since gtkmm 2.12:

Parameters

domain The translation domain or nullptr.
