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 2. 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:

Example 3. A non-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));

 /* 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);

Details

GtkMessageDialog

typedef struct _GtkMessageDialog GtkMessageDialog;


enum GtkMessageType

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

The type of message being displayed in the dialog.

GTK_MESSAGE_INFOInformational message
GTK_MESSAGE_WARNINGNonfatal warning message
GTK_MESSAGE_QUESTIONQuestion requiring a choice
GTK_MESSAGE_ERRORFatal error message

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().

GTK_BUTTONS_NONEno buttons at all
GTK_BUTTONS_OKan OK button
GTK_BUTTONS_CLOSEa Close button
GTK_BUTTONS_CANCELa Cancel button
GTK_BUTTONS_YES_NOYes and No buttons
GTK_BUTTONS_OK_CANCELOK and Cancel buttons

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.

parent : transient parent, or NULL for none
flags : flags
type : type of message
buttons : set of buttons to use
message_format : printf()-style format string, or NULL
... : arguments for message_format
Returns : a new GtkMessageDialog

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.

 GtkWidget *dialog;
 dialog = gtk_message_dialog_new (main_application_window,
                                  GTK_DIALOG_DESTROY_WITH_PARENT,
                                  GTK_MESSAGE_ERROR,
                                  GTK_BUTTON_CLOSE,
                                  NULL);
 gtk_message_dialog_set_markup (GTK_MESSAGE_DIALOG (dialog),
                                markup);

parent : transient parent, or NULL for none
flags : flags
type : type of message
buttons : set of buttons to use
message_format : printf()-style format string, or NULL
... : arguments for message_format
Returns : a new GtkMessageDialog

Since 2.4


gtk_message_dialog_set_markup ()

void        gtk_message_dialog_set_markup   (GtkMessageDialog *message_dialog,
                                             const gchar *str);

Sets the text of the message dialog to be str, which is marked up with the Pango text markup language.

message_dialog : a GtkMessageDialog
str : markup string (see Pango markup format)

Since 2.4


gtk_message_dialog_format_secondary_text ()

void        gtk_message_dialog_format_secondary_text
                                            (GtkMessageDialog *message_dialog,
                                             const gchar *message_format,
                                             ...);

Sets the secondary text of the message dialog to be message_format (with printf()-style).

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

message_dialog : a GtkMessageDialog
message_format : printf()-style format string, or NULL
... : arguments for message_format

gtk_message_dialog_format_secondary_markup ()

                                             ...);

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.
