/**
* GtkInfoBar :
*
* ` GtkInfoBar ` can be used to show messages to the user without a dialog .
*
* < picture >
* < source srcset = " info - bar - dark . png " media = " ( prefers - color - scheme : dark ) " >
* < img alt = " An example GtkInfoBar " src = " info - bar . png " >
* < / picture >
*
* It is often temporarily shown at the top or bottom of a document .
* In contrast to [ class @ Gtk . Dialog ] , which has an action area at the
* bottom , ` GtkInfoBar ` has an action area at the side .
*
* The API of ` GtkInfoBar ` is very similar to ` GtkDialog ` , allowing you
* to add buttons to the action area with [ method @ Gtk . InfoBar . add_button ]
* or [ ctor @ Gtk . InfoBar . new_with_buttons ] . The sensitivity of action widgets
* can be controlled with [ method @ Gtk . InfoBar . set_response_sensitive ] .
*
* To add widgets to the main content area of a ` GtkInfoBar ` , use
* [ method @ Gtk . InfoBar . add_child ] .
*
* Similar to [ class @ Gtk . MessageDialog ] , the contents of a ` GtkInfoBar `
* can by classified as error message , warning , informational message , etc ,
* by using [ method @ Gtk . InfoBar . set_message_type ] . GTK may use the message
* type to determine how the message is displayed .
*
* A simple example for using a ` GtkInfoBar ` :
* ` ` ` c
* GtkWidget * message_label ;
* GtkWidget * widget ;
* GtkWidget * grid ;
* GtkInfoBar * bar ;
*
* // set up info bar
* widget = gtk_info_bar_new ( ) ;
* bar = GTK_INFO_BAR ( widget ) ;
* grid = gtk_grid_new ( ) ;
*
* message_label = gtk_label_new ( " " ) ;
* gtk_info_bar_add_child ( bar , message_label ) ;
* gtk_info_bar_add_button ( bar ,
* _ ( " _ OK " ) ,
* GTK_RESPONSE_OK ) ;
* g_signal_connect ( bar ,
* " response " ,
* G_CALLBACK ( gtk_widget_hide ) ,
* NULL ) ;
* gtk_grid_attach ( GTK_GRID ( grid ) ,
* widget ,
* 0 , 2 , 1 , 1 ) ;
*
* // ...
*
* // show an error message
* gtk_label_set_text ( GTK_LABEL ( message_label ) , " An error occurred ! " ) ;
* gtk_info_bar_set_message_type ( bar , GTK_MESSAGE_ERROR ) ;
* gtk_widget_show ( bar ) ;
* ` ` `
*
* # GtkInfoBar as GtkBuildable
*
* ` GtkInfoBar ` supports a custom ` < action - widgets > ` element , which can contain
* multiple ` < action - widget > ` elements . The “ response ” attribute specifies a
* numeric response , and the content of the element is the id of widget
* ( which should be a child of the dialogs @ action_area ) .
*
* ` GtkInfoBar ` supports adding action widgets by specifying “ action ” as
* the “ type ” attribute of a ` < child > ` element . The widget will be added
* either to the action area . The response id has to be associated
* with the action widget using the ` < action - widgets > ` element .
*
* # CSS nodes
*
* ` GtkInfoBar ` has a single CSS node with name infobar . The node may get
* one of the style classes . info , . warning , . error or . question , depending
* on the message type .
* If the info bar shows a close button , that button will have the . close
* style class applied .
*
* Deprecated : 4 . 10 : There is no replacement in GTK for an " info bar " widget ;
* you can use [ class @ Gtk . Revealer ] with a [ class @ Gtk . Box ] containing a
* [ class @ Gtk . Label ] and an optional [ class @ Gtk . Button ] , according to
* your application ' s design .
