## 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.

Glib::RefPtr<Application> Gtk::Builder::get_application | ( |  | ) |

Gets the Gtk::Application associated with the builder.

The Gtk::Application is used for creating action proxies as requested from XML that the builder is loading.

By default, the builder uses the default application: the one from Glib::application_get_default(). If you want to use another application for constructing proxies, use set_application().

Since gtkmm 3.10:

Returns
  The application being used by the builder, or `0`.

Glib::RefPtr<const Application> Gtk::Builder::get_application | ( |  | ) | const

Gets the Gtk::Application associated with the builder.

The Gtk::Application is used for creating action proxies as requested from XML that the builder is loading.

By default, the builder uses the default application: the one from Glib::application_get_default(). If you want to use another application for constructing proxies, use set_application().

Since gtkmm 3.10:

Returns
  The application being used by the builder, or `0`.

Glib::RefPtr<Glib::Object> Gtk::Builder::get_object | ( | const Glib::ustring & | name | ) |

Gets the object named name.

Since gtkmm 2.12:

Parameters

  name | Name of object to get.

Returns
  The object named name or `0` if it could not be found in the object tree.

Glib::RefPtr<const Glib::Object> Gtk::Builder::get_object | ( | const Glib::ustring & | name | ) | const

Gets the object named name.

Since gtkmm 3.8:

Parameters

  name | Name of object to get.

Returns
  The object named name or `0` if it could not be found in the object tree.

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.

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.

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.

static GType Gtk::Builder::get_type | ( |  | ) |

static

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

template <class T_Widget >

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

inline

Get a widget from the Builder file.

For instance:

Gtk::Grid* pGrid = nullptr;
refXml->get_widget("mygrid", pGrid);

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.

Return values

  widget | A pointer to the widget, or `0` on failure.

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:

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

protected

template <class T_Widget >

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

inline

This provides a pointer to 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:

DerivedDialog::DerivedDialog(BaseObjectType* cobject, const Glib::RefPtr<Gtk::Builder>& refBuilder)
: Gtk::Dialog(cobject) //Calls the base class constructor

For instance:

Gtk::DerivedBox* pBox = nullptr;
refXml->get_widget_derived("mybox", pBox);

Parameters

  name | The name of the widget.

Return values

  widget | A pointer to the widget, or `0` on failure.

template <class T_Widget >

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

inline

See the non-const version.

Since gtkmm 3.8:

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

inline

Provides access to the underlying C GObject.

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

inline

Provides access to the underlying C GObject.

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.

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

noexcept

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 `0`, Gtk::Builder uses gettext(), otherwise Glib::dgettext().

Since gtkmm 2.12:

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.

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 `0`, Gtk::Builder uses gettext(), otherwise Glib::dgettext().

Since gtkmm 2.12:

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

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 Application in your process. application cannot be `0`.

Since gtkmm 3.10:

Parameters

  application | A Gtk::Application.

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 `0`.
