"message-type" GtkMessageType : Read / Write / Construct "buttons" GtkButtonsType : Write / Construct Only |
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 1. 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 2. 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 (GTK_OBJECT (dialog), "response",
G_CALLBACK (gtk_widget_destroy),
GTK_OBJECT (dialog));

typedef enum
{
GTK_MESSAGE_INFO,
GTK_MESSAGE_WARNING,
GTK_MESSAGE_QUESTION,
GTK_MESSAGE_ERROR
} GtkMessageType;
|
The type of message being displayed in the dialog.
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().
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.
