Description

GtkMessageDialog presents a dialog with an image representing the type of message (Error, Question, etc.) alongside some message text. It's simply a convenience widget; you could construct the equivalent of GtkMessageDialog from GtkDialog without too much effort, but GtkMessageDialog saves typing.

The easiest way to do a modal message dialog is to use gtk_dialog_run(), though you can also pass in the GTK_DIALOG_MODAL flag, gtk_dialog_run() automatically makes the dialog modal and waits for the user to respond to it. gtk_dialog_run() returns when any dialog button is clicked.

Example 46. A modal dialog.

dialog = gtk_message_dialog_new (main_application_window,
                                 GTK_DIALOG_DESTROY_WITH_PARENT,
                                 GTK_MESSAGE_ERROR,
                                 GTK_BUTTONS_CLOSE,
                                 "Error loading file '%s': %s",
                                 filename, g_strerror (errno));
gtk_dialog_run (GTK_DIALOG (dialog));
gtk_widget_destroy (dialog);


You might do a non-modal GtkMessageDialog as follows:

                                 GTK_MESSAGE_ERROR,
                                 GTK_BUTTONS_CLOSE,
                                 "Error loading file '%s': %s",
                                 filename, g_strerror (errno));

/* Destroy the dialog when the user responds to it (e.g. clicks a button) */
g_signal_connect_swapped (dialog, "response",
                          G_CALLBACK (gtk_widget_destroy),
                          dialog);


GtkMessageDialog as GtkBuildable

The GtkMessageDialog implementation of the GtkBuildable interface exposes the message area as an internal child with the name "message_area".

Details

struct GtkMessageDialog

struct GtkMessageDialog;


enum GtkMessageType

typedef enum
{
  GTK_MESSAGE_INFO,
  GTK_MESSAGE_WARNING,
  GTK_MESSAGE_QUESTION,
  GTK_MESSAGE_ERROR,
  GTK_MESSAGE_OTHER
} GtkMessageType;

The type of message being displayed in the dialog.

GTK_MESSAGE_INFO

Informational message

GTK_MESSAGE_WARNING

Nonfatal warning message

GTK_MESSAGE_QUESTION

Question requiring a choice

GTK_MESSAGE_ERROR

Fatal error message

GTK_MESSAGE_OTHER

None of the above, doesn't get an icon

enum GtkButtonsType

typedef enum
{
  GTK_BUTTONS_NONE,
  GTK_BUTTONS_OK,
  GTK_BUTTONS_CLOSE,
  GTK_BUTTONS_CANCEL,
  GTK_BUTTONS_YES_NO,
  GTK_BUTTONS_OK_CANCEL
} GtkButtonsType;

Prebuilt sets of buttons for the dialog. If none of these choices are appropriate, simply use GTK_BUTTONS_NONE then call gtk_dialog_add_buttons().

Note

Please note that GTK_BUTTONS_OK, GTK_BUTTONS_YES_NO and GTK_BUTTONS_OK_CANCEL are discouraged by the GNOME HIG.

GTK_BUTTONS_NONE

no buttons at all

GTK_BUTTONS_OK

an OK button

GTK_BUTTONS_CLOSE

a Close button

GTK_BUTTONS_CANCEL

a Cancel button

GTK_BUTTONS_YES_NO

gtk_message_dialog_new ()

GtkWidget *         gtk_message_dialog_new              (GtkWindow *parent,
                                                         GtkDialogFlags flags,
                                                         GtkMessageType type,
                                                         GtkButtonsType buttons,
                                                         const gchar *message_format,
                                                         ...);

Creates a new message dialog, which is a simple dialog with an icon indicating the dialog type (error, warning, etc.) and some text the user may want to see. When the user clicks a button a "response" signal is emitted with response IDs from GtkResponseType. See GtkDialog for more details.

gtk_message_dialog_new_with_markup ()

GtkWidget *         gtk_message_dialog_new_with_markup  (GtkWindow *parent,
                                                         GtkDialogFlags flags,
                                                         GtkMessageType type,
                                                         GtkButtonsType buttons,
                                                         const gchar *message_format,
                                                         ...);

Creates a new message dialog, which is a simple dialog with an icon indicating the dialog type (error, warning, etc.) and some text which is marked up with the Pango text markup language. When the user clicks a button a "response" signal is emitted with response IDs from GtkResponseType. See GtkDialog for more details.

Special XML characters in the printf() arguments passed to this function will automatically be escaped as necessary. (See g_markup_printf_escaped() for how this is implemented.) Usually this is what you want, but if you have an existing Pango markup string that you want to use literally as the label, then you need to use gtk_message_dialog_set_markup() instead, since you can't pass the markup string either as the format (it might contain '%' characters) or as a string argument.

Note that setting a secondary text makes the primary text become bold, unless you have provided explicit markup.

gtk_message_dialog_format_secondary_markup ()

void                gtk_message_dialog_format_secondary_markup
                                                        (GtkMessageDialog *message_dialog,

                                                         ...);

Sets the secondary text of the message dialog to be message_format (with printf()-style), which is marked up with the Pango text markup language.

Note that setting a secondary text makes the primary text become bold, unless you have provided explicit markup.

Due to an oversight, this function does not escape special XML characters like gtk_message_dialog_new_with_markup() does. Thus, if the arguments may contain special XML characters, you should use g_markup_printf_escaped() to escape it.

gtk_message_dialog_get_message_area ()

GtkWidget *         gtk_message_dialog_get_message_area (GtkMessageDialog *message_dialog);

Returns the message area of the dialog. This is the box where the dialog's primary and secondary labels are packed. You can add your own extra content to that box and it will appear below those labels, on the right side of the dialog's image (or on the left for right-to-left languages). See gtk_dialog_get_content_area() for the corresponding function in the parent GtkDialog.
