Description

GtkInfoBar is a widget that can be used to show messages to the user without showing a dialog. It is often temporarily shown at the top or bottom of a document. In contrast to GtkDialog, which has a horizontal action area at the bottom, GtkInfoBar has a vertical action area at the side.

The API of GtkInfoBar is very similar to GtkDialog, allowing you to add buttons to the action area with gtk_info_bar_add_button() or gtk_info_bar_new_with_buttons(). The sensitivity of action widgets can be controlled with gtk_info_bar_set_response_sensitive(). To add widgets to the main content area of a GtkInfoBar, use gtk_info_bar_get_content_area() and add your widgets to the container.

Similar to GtkMessageDialog, the contents of a GtkInfoBar can by classified as error message, warning, informational message, etc, by using gtk_info_bar_set_message_type(). GTK+ uses the message type to determine the background color of the message area.

GtkInfoBar as GtkBuildable

The GtkInfoBar implementation of the GtkBuildable interface exposes the content area and action area as internal children with the names "content_area" and "action_area".

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).

Details

struct GtkInfoBar

struct GtkInfoBar;


gtk_info_bar_new ()

GtkWidget *         gtk_info_bar_new                    (void);

Creates a new GtkInfoBar object.

Returns :

a new GtkInfoBar object

Since 2.18


gtk_info_bar_new_with_buttons ()

GtkWidget *         gtk_info_bar_new_with_buttons       (const gchar *first_button_text,
                                                         ...);

Creates a new GtkInfoBar with buttons. Button text/response ID pairs should be listed, with a NULL pointer ending the list. Button text can be either a stock ID such as GTK_STOCK_OK, or some arbitrary text. A response ID can be any positive number, or one of the values in the GtkResponseType enumeration. If the user clicks one of these dialog buttons, GtkInfoBar will emit the "response" signal with the corresponding response ID.

first_button_text :

stock ID or text to go in first button, or NULL. [allow-none]

... :

response ID for first button, then additional buttons, ending with NULL

Returns :

a new GtkInfoBar

gtk_info_bar_add_action_widget ()

void                gtk_info_bar_add_action_widget      (GtkInfoBar *info_bar,
                                                         GtkWidget *child,
                                                         gint response_id);

Add an activatable widget to the action area of a GtkInfoBar, connecting a signal handler that will emit the "response" signal on the message area when the widget is activated. The widget is appended to the end of the message areas action area.

info_bar :

a GtkInfoBar

child :

an activatable widget

response_id :

response ID for child

Since 2.18


gtk_info_bar_add_button ()

GtkWidget *         gtk_info_bar_add_button             (GtkInfoBar *info_bar,

                                                         gint response_id);

Adds a button with the given text (or a stock button, if button_text is a stock ID) and sets things up so that clicking the button will emit the "response" signal with the given response_id. The button is appended to the end of the info bars's action area. The button widget is returned, but usually you don't need it.

info_bar :

text of button, or stock ID

response_id :

response ID for the button

Returns :

the button widget that was added. [transfer none]

                                                         ...);

Adds more buttons, same as calling gtk_info_bar_add_button() repeatedly. The variable argument list should be NULL-terminated as with gtk_info_bar_new_with_buttons(). Each button must have both text and response ID.
