/**
* GtkBuilder :
*
* Reads XML descriptions of a user interface and instantiates the described objects .
*
* To create a ` GtkBuilder ` from a user interface description , call
* [ ctor @ Gtk . Builder . new_from_file ] , [ ctor @ Gtk . Builder . new_from_resource ]
* or [ ctor @ Gtk . Builder . new_from_string ] .
*
* In the ( unusual ) case that you want to add user interface
* descriptions from multiple sources to the same ` GtkBuilder ` you can
* call [ ctor @ Gtk . Builder . new ] to get an empty builder and populate it by
* ( multiple ) calls to [ method @ Gtk . Builder . add_from_file ] ,
* [ method @ Gtk . Builder . add_from_resource ] or
* [ method @ Gtk . Builder . add_from_string ] .
*
* A ` GtkBuilder ` holds a reference to all objects that it has constructed
* and drops these references when it is finalized . This finalization 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 call
* [ method @ Gtk . Window . destroy ] to get rid of them and all the widgets
* they contain .
*
* The functions [ method @ Gtk . Builder . get_object ] and
* [ method @ Gtk . Builder . get_objects ] 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 functions will stay around until the
* user explicitly destroys them with [ method @ Gtk . Window . destroy ] . 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
* to make use of them . Non - widget objects need to be reffed with
* g_object_ref ( ) to keep them beyond the lifespan of the builder .
*
* # # GtkBuilder UI Definitions
*
* ` GtkBuilder ` parses textual descriptions of user interfaces which are
* specified in XML format . We refer to these descriptions as “ GtkBuilder
* UI definitions ” or just “ UI definitions ” if the context is clear .
*
* # # # Structure of UI definitions
*
* UI definition files are always encoded in UTF - 8 .
*
* The toplevel element is ` < interface > ` . It optionally takes a “ domain ”
* attribute , which will make the builder look for translated strings
* using ` dgettext ( ) ` in the domain specified . This can also be done by
* calling [ method @ Gtk . Builder . set_translation_domain ] on the builder .
* For example :
*
* ` ` ` xml
* < ? xml version = " 1 . 0 " encoding = " UTF - 8 " ? >
* < interface domain = " your - app " >
* . . .
* < / interface >
* ` ` `
*
* # # # Requirements
*
* The target toolkit version ( s ) are described by ` < requires > ` elements ,
* the “ lib ” attribute specifies the widget library in question ( currently
* the only supported value is “ gtk ” ) and the “ version ” attribute specifies
* the target version in the form “ ` < major > ` . ` < minor > ` ” . ` GtkBuilder ` will
* error out if the version requirements are not met . For example :
*
* ` ` ` xml
* < ? xml version = " 1 . 0 " encoding = " UTF - 8 " ? >
* < interface domain = " your - app " >
* < requires lib = " gtk " version = " 4 . 0 " / >
* < / interface >
* ` ` `
*
* # # # Objects
*
* Objects are defined as children of the ` < interface > ` element .
*
* Objects are described by ` < object > ` elements , which can contain
* ` < property > ` elements to set properties , ` < signal > ` elements which
* connect signals to handlers , and ` < child > ` elements , which describe
* child objects .
*
* Typically , the specific kind of object represented by an ` < object > `
* element is specified by the “ class ” attribute . If the type has not
* been loaded yet , GTK tries to find the ` get_type ( ) ` function from the
* class name by applying heuristics . This works in most cases , but if
* necessary , it is possible to specify the name of the ` get_type ( ) `
* function explicitly with the " type - func " attribute . If your UI definition
* is referencing internal types , you should make sure to call
* ` g_type_ensure ( ) ` for each object type before parsing the UI definition .
*
* Objects may be given a name with the “ id ” attribute , which allows the
* application to retrieve them from the builder with
* [ method @ Gtk . Builder . get_object ] . An id is also necessary to use the
* object as property value in other parts of the UI definition . GTK
* reserves ids starting and ending with ` _ _ _ ` ( three consecutive
* underscores ) for its own purposes .
*
* # # # Properties
*
* Setting properties of objects is pretty straightforward with the
* ` < property > ` element : the “ name ” attribute specifies the name of the
* property , and the content of the element specifies the value :
*
* ` ` ` xml
* < object class = " GtkButton " >
* < property name = " label " > Hello , world < / property >
* < / object >
* ` ` `
*
* If the “ translatable ” attribute is set to a true value , GTK uses
* ` gettext ( ) ` ( or ` dgettext ( ) ` if the builder has a translation domain set )
* to find a translation for the value . This happens before the value
* is parsed , so it can be used for properties of any type , but it is
* probably most useful for string properties . It is also possible to
* specify a context to disambiguate short strings , and comments which
* may help the translators :
*
* ` ` ` xml
* < object class = " GtkButton " >
* < property name = " label "
* translatable = " yes "
* context = " button "
* comments = " A classic " > Hello , world < / property >
* < / object >
* ` ` `
*
* The xgettext tool that is part of gettext can extract these strings ,
* but note that it only looks for translatable = " yes " .
*
* ` GtkBuilder ` can parse textual representations for the most common
* property types :
*
* - characters
* - strings
* - integers
* - floating - point numbers
* - booleans ( strings like “ TRUE ” , “ t ” , “ yes ” , “ y ” , “ 1 ” are interpreted
* as true values , strings like “ FALSE ” , “ f ” , “ no ” , “ n ” , “ 0 ” are interpreted
* as false values )
* - string lists ( separated by newlines )
* - enumeration types ( can be specified by their full C identifier their short
* name used when registering the enumeration type , or their integer value )
* - flag types ( can be specified by their C identifier or short name ,
* optionally combined with “ | ” for bitwise OR , or a single integer value
* e . g . , “ GTK_INPUT_HINT_EMOJI | GTK_INPUT_HINT_LOWERCASE ” , or “ emoji | lowercase ” or 520 ) .
* - colors ( in the format understood by [ method @ Gdk . RGBA . parse ] )
* - transforms ( in the format understood by [ func @ Gsk . Transform . parse ] )
* - Pango attribute lists ( in the format understood by [ method @ Pango . AttrList . to_string ] )
* - Pango tab arrays ( in the format understood by [ method @ Pango . TabArray . to_string ] )
* - Pango font descriptions ( in the format understood by [ func @ Pango . FontDescription . from_string ] )
* - ` GVariant ` ( in the format understood by [ func @ GLib . Variant . parse ] )
* - textures ( can be specified as an object id , a resource path or a filename of an image file to load relative to the Builder file or the CWD if [ method @ Gtk . Builder . add_from_string ] was used )
* - GFile ( like textures , can be specified as an object id , a URI or a filename of a file to load relative to the Builder file or the CWD if [ method @ Gtk . Builder . add_from_string ] was used )
*
* Objects can be referred to by their name and by default refer to
* objects declared in the local XML fragment and objects exposed via
* [ method @ Gtk . Builder . expose_object ] . In general , ` GtkBuilder ` allows
* forward references to objects declared in the local XML ; an object
* doesn ’ t have to be constructed before it can be referred to . The
* exception to this rule is that an object has to be constructed before
* it can be used as the value of a construct - only property .
*
* # # # Child objects
*
* Many widgets have properties for child widgets , such as
* [ property @ Gtk . Expander : child ] . In this case , the preferred way to
* specify the child widget in a ui file is to simply set the property :
*
* ` ` ` xml
* < object class = " GtkExpander " >
* < property name = " child " >
* < object class = " GtkLabel " >
* . . .
* < / object >
* < / property >
* < / object >
* ` ` `
*
* Generic containers that can contain an arbitrary number of children ,
* such as [ class @ Gtk . Box ] instead use the ` < child > ` element . A ` < child > `
* element contains an ` < object > ` element which describes the child object .
* Most often , child objects are widgets inside a container , but they can
* also be , e . g . , actions in an action group , or columns in a tree model .
*
* Any object type that implements the [ iface @ Gtk . Buildable ] interface can
* specify how children may be added to it . Since many objects and widgets that
* are included with GTK already implement the ` GtkBuildable ` interface ,
* typically child objects can be added using the ` < child > ` element without
* having to be concerned about the underlying implementation .
*
* See the [ ` GtkWidget ` documentation ] ( class . Widget . html # gtkwidget - as - gtkbuildable )
* for many examples of using ` GtkBuilder ` with widgets , including setting
* child objects using the ` < child > ` element .
*
* A noteworthy special case to the general rule that only objects implementing
* ` GtkBuildable ` may specify how to handle the ` < child > ` element is that
* ` GtkBuilder ` provides special support for adding objects to a
* [ class @ Gio . ListStore ] by using the ` < child > ` element . For instance :
*
* ` ` ` xml
* < object class = " GListStore " >
* < property name = " item - type " > MyObject < / property >
* < child >
* < object class = " MyObject " / >
* < / child >
* . . .
* < / object >
* ` ` `
*
* # # # Property bindings
*
* It is also possible to bind a property value to another object ' s
* property value using the attributes " bind - source " to specify the
* source object of the binding , and optionally , " bind - property " and
* " bind - flags " to specify the source property and source binding flags
* respectively . Internally , ` GtkBuilder ` implements this using
* [ class @ GObject . Binding ] objects .
*
* For instance , in the example below the “ label ” property of the
* ` bottom_label ` widget is bound to the “ label ” property of the
* ` top_button ` widget :
*
* ` ` ` xml
* < object class = " GtkBox " >
* < property name = " orientation " > vertical < / property >
* < child >
* < object class = " GtkButton " id = " top_button " >
* < property name = " label " > Hello , world < / property >
* < / object >
* < / child >
* < child >
* < object class = " GtkLabel " id = " bottom_label " >
* < property name = " label "
* bind - source = " top_button "
* bind - property = " label "
* bind - flags = " sync - create " / >
* < / object >
* < / child >
* < / object >
* ` ` `
*
* For more information , see the documentation of the
* [ method @ GObject . Object . bind_property ] method .
*
* Please note that another way to set up bindings between objects in . ui files
* is to use the ` GtkExpression ` methodology . See the
* [ ` GtkExpression ` documentation ] ( class . Expression . html # gtkexpression - in - ui - files )
* for more information .
*
* # # # Internal children
*
* Sometimes it is necessary to refer to widgets which have implicitly
* been constructed by GTK as part of a composite widget , to set
* properties on them or to add further children ( e . g . the content area
* of a ` GtkDialog ` ) . This can be achieved by setting the “ internal - child ”
* property of the ` < child > ` element to a true value . Note that ` GtkBuilder `
* still requires an ` < object > ` element for the internal child , even if it
* has already been constructed .
*
* # # # Specialized children
*
* A number of widgets have different places where a child can be added
* ( e . g . tabs vs . page content in notebooks ) . This can be reflected in
* a UI definition by specifying the “ type ” attribute on a ` < child > `
* The possible values for the “ type ” attribute are described in the
* sections describing the widget - specific portions of UI definitions .
*
* # # # Signal handlers and function pointers
*
* Signal handlers are set up with the ` < signal > ` element . The “ name ”
* attribute specifies the name of the signal , and the “ handler ” attribute
* specifies the function to connect to the signal .
*
* ` ` ` xml
* < object class = " GtkButton " id = " hello_button " >
* < signal name = " clicked " handler = " hello_button__clicked " / >
* < / object >
* ` ` `
*
* The remaining attributes , “ after ” , “ swapped ” and “ object ” , have the
* same meaning as the corresponding parameters of the
* [ func @ GObject . signal_connect_object ] or [ func @ GObject . signal_connect_data ]
* functions :
*
* - “ after ” matches the ` G_CONNECT_AFTER ` flag , and will ensure that the
* handler is called after the default class closure for the signal
* - “ swapped ” matches the ` G_CONNECT_SWAPPED ` flag , and will swap the
* instance and closure arguments when invoking the signal handler
* - “ object ” will bind the signal handler to the lifetime of the object
* referenced by the attribute
*
* By default " swapped " will be set to " yes " if not specified otherwise , in
* the case where " object " is set , for convenience . A “ last_modification_time ”
* attribute is also allowed , but it does not have a meaning to the builder .
*
* When compiling applications for Windows , you must declare signal callbacks
* with the ` G_MODULE_EXPORT ` decorator , or they will not be put in the symbol
* table :
*
* ` ` ` c
* G_MODULE_EXPORT void
* hello_button__clicked ( GtkButton * button ,
* gpointer data )
* {
* // ...
* }
* ` ` `
*
* On Linux and Unix , this is not necessary ; applications should instead
* be compiled with the ` - Wl , - - export - dynamic ` argument inside their compiler
* flags , and linked against ` gmodule - export - 2 . 0 ` .
*
* # # Example UI Definition
*
* ` ` ` xml
* < interface >
* < object class = " GtkDialog " id = " dialog1 " >
* < child internal - child = " content_area " >
* < object class = " GtkBox " >
* < child internal - child = " action_area " >
* < object class = " GtkBox " >
* < child >
* < object class = " GtkButton " id = " ok_button " >
* < property name = " label " translatable = " yes " > _ Ok < / property >
* < property name = " use - underline " > True < / property >
* < signal name = " clicked " handler = " ok_button_clicked " / >
* < / object >
* < / child >
* < / object >
* < / child >
* < / object >
* < / child >
* < / object >
* < / interface >
* ` ` `
*
* # # Using GtkBuildable for extending UI definitions
*
* Objects can implement the [ iface @ Gtk . Buildable ] interface to add custom
* elements and attributes to the XML . Typically , any extension will be
* documented in each type that implements the interface .
*
* # # Menus
*
* In addition to objects with properties that are created with ` < object > ` and
* ` < property > ` elements , ` GtkBuilder ` also allows to parse XML menu definitions
* as used by [ class @ Gio . Menu ] when exporting menu models over D - Bus , and as
* described in the [ class @ Gtk . PopoverMenu ] documentation . Menus can be defined
* as toplevel elements , or as property values for properties of type ` GMenuModel ` .
*
* # # Templates
*
* When describing a [ class @ Gtk . Widget ] , you can use the ` < template > ` tag to
* describe a UI bound to a specific widget type . GTK will automatically load
* the UI definition when instantiating the type , and bind children and
* signal handlers to instance fields and function symbols .
*
* For more information , see the [ ` GtkWidget ` documentation ] ( class . Widget . html # building - composite - widgets - from - template - xml )
* for details .
