## Detailed Description

Build an interface from a 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 interface is created. The Gtk::Builder object then provides an interface for accessing the widgets in the interface by the names assigned to them inside the UI description.

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

Gets the object named name.

Note that this function does not increment the reference count of the returned object.

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

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::Table* pTable = 0;
     refXml->get_widget("mytable", pTable);

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.

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

| ) |  | `[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 = 0;
     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.

GtkBuilder* Gtk::Builder::gobj | ( |  | ) | `[inline]`

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

The translation domain used by gettext.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

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

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

The translation domain used by gettext.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

See Gtk::Builder:translation-domain.

Since gtkmm 2.12:

Parameters:

  domain | The translation domain or `0`.
