MessageDialog

#GtkMessageDialog presents a dialog with 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.

One difference from #GtkDialog is that #GtkMessageDialog sets the #GtkWindow:skip-taskbar-hint property to %TRUE, so that the dialog is hidden from the taskbar by default.

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.

An example for using a modal dialog: |[ GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT; dialog = gtk_message_dialog_new (parent_window, flags, GTK_MESSAGE_ERROR, GTK_BUTTONS_CLOSE, "Error reading “%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:

An example for a non-modal dialog: |[ GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT; dialog = gtk_message_dialog_new (parent_window, flags, GTK_MESSAGE_ERROR, GTK_BUTTONS_CLOSE, "Error reading “%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”.

class MessageDialog : Dialog {

protected

GtkMessageDialog* gtkMessageDialog;

GtkMessageDialog* getMessageDialogStruct(bool transferOwnership);

void* getStruct();

void setStruct(GObject* obj);

this(GtkMessageDialog* gtkMessageDialog, bool ownedRef);

this(Window parent, GtkDialogFlags flags, GtkMessageType type, GtkButtonsType buttons, string messageFormat, string message);

this(Window parent, GtkDialogFlags flags, GtkMessageType type, GtkButtonsType buttons, bool markup, string messageFormat, string message);

VBox getMessageArea();

static GType getType();

Widget getImage();

}

Constructors

this this(GtkMessageDialog* gtkMessageDialog, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(Window parent, GtkDialogFlags flags, GtkMessageType type, GtkButtonsType buttons, string messageFormat, string message): 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.
this this(Window parent, GtkDialogFlags flags, GtkMessageType type, GtkButtonsType buttons, bool markup, string messageFormat, string message): 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.

From Dialog

gtkDialog GtkDialog* gtkDialog;: the main Gtk struct
getDialogStruct GtkDialog* getDialogStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
setStruct void setStruct(GObject* obj): Undocumented in source. Be warned that the author may not have intended to support it.
addButton Button addButton(StockID stockID, int responseId)
addButtons void addButtons(string[] buttonsText, ResponseType[] responses)
addButtons void addButtons(StockID[] stockIDs, ResponseType[] responses)
getActionArea HButtonBox getActionArea(): Returns the action area of dialog.
getContentArea VBox getContentArea(): Returns the content area of dialog.
getType GType getType()
addActionWidget void addActionWidget(Widget child, int responseId): Adds an activatable widget to the action area of a #GtkDialog, connecting a signal handler that will emit the #GtkDialog::response signal on the dialog when the widget is activated. The widget is appended to the end of the dialog’s action area. If you want to add a non-activatable widget, simply pack it into the @action_area field of the #GtkDialog struct.
addButton Widget addButton(string buttonText, int responseId): Adds a button with the given text and sets things up so that clicking the button will emit the #GtkDialog::response signal with the given @response_id. The button is appended to the end of the dialog’s action area. The button widget is returned, but usually you don’t need it.
getHeaderBar Widget getHeaderBar(): Returns the header bar of @dialog. Note that the headerbar is only used by the dialog if the #GtkDialog:use-header-bar property is %TRUE.
getResponseForWidget int getResponseForWidget(Widget widget): Gets the response id of a widget in the action area of a dialog.
getWidgetForResponse Widget getWidgetForResponse(int responseId): Gets the widget button that uses the given response ID in the action area of a dialog.
response void response(int responseId): Emits the #GtkDialog::response signal with the given response ID. Used to indicate that the user has responded to the dialog in some way; typically either you or gtk_dialog_run() will be monitoring the ::response signal and take appropriate action.
run int run(): Blocks in a recursive main loop until the @dialog either emits the #GtkDialog::response signal, or is destroyed. If the dialog is destroyed during the call to gtk_dialog_run(), gtk_dialog_run() returns #GTK_RESPONSE_NONE. Otherwise, it returns the response ID from the ::response signal emission.
setAlternativeButtonOrder void setAlternativeButtonOrder(int[] newOrder): Sets an alternative button order. If the #GtkSettings:gtk-alternative-button-order setting is set to %TRUE, the dialog buttons are reordered according to the order of the response ids in @new_order.
setDefaultResponse void setDefaultResponse(int responseId): Sets the last widget in the dialog’s action area with the given @response_id as the default widget for the dialog. Pressing “Enter” normally activates the default widget.
setResponseSensitive void setResponseSensitive(int responseId, bool setting): Calls gtk_widget_set_sensitive (widget, @setting) for each widget in the dialog’s action area with the given @response_id. A convenient way to sensitize/desensitize dialog buttons.
OnCloseDelegateWrapper class OnCloseDelegateWrapper: Undocumented in source.
onCloseListeners OnCloseDelegateWrapper[] onCloseListeners;: Undocumented in source.
addOnClose gulong addOnClose(void delegate(Dialog) dlg, ConnectFlags connectFlags): The ::close signal is a [keybinding signal]GtkBindingSignal which gets emitted when the user uses a keybinding to close the dialog.
callBackClose void callBackClose(GtkDialog* dialogStruct, OnCloseDelegateWrapper wrapper): Undocumented in source. Be warned that the author may not have intended to support it.
callBackCloseDestroy void callBackCloseDestroy(OnCloseDelegateWrapper wrapper, GClosure* closure): Undocumented in source. Be warned that the author may not have intended to support it.
OnResponseDelegateWrapper class OnResponseDelegateWrapper: Undocumented in source.
onResponseListeners OnResponseDelegateWrapper[] onResponseListeners;: Undocumented in source.
addOnResponse gulong addOnResponse(void delegate(int, Dialog) dlg, ConnectFlags connectFlags): Emitted when an action widget is clicked, the dialog receives a delete event, or the application programmer calls gtk_dialog_response(). On a delete event, the response ID is #GTK_RESPONSE_DELETE_EVENT. Otherwise, it depends on which action widget was clicked.
callBackResponse void callBackResponse(GtkDialog* dialogStruct, int responseId, OnResponseDelegateWrapper wrapper): Undocumented in source. Be warned that the author may not have intended to support it.
callBackResponseDestroy void callBackResponseDestroy(OnResponseDelegateWrapper wrapper, GClosure* closure): Undocumented in source. Be warned that the author may not have intended to support it.
alternativeDialogButtonOrder bool alternativeDialogButtonOrder(Screen screen): Returns %TRUE if dialogs are expected to use an alternative button order on the screen @screen. See gtk_dialog_set_alternative_button_order() for more details about alternative button order.
