pub struct MessageDialog { /* private fields */ }
Expand description

MessageDialog presents a dialog with some message text. It’s simply a convenience widget; you could construct the equivalent of MessageDialog from Dialog without too much effort, but MessageDialog saves typing.

One difference from Dialog is that MessageDialog sets the property::Window::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 DialogExt::run(), though you can also pass in the DialogFlags::MODAL flag, DialogExt::run() automatically makes the dialog modal and waits for the user to respond to it. DialogExt::run() returns when any dialog button is clicked.

An example for using a modal dialog:

⚠️ The following code is in C ⚠️

 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 MessageDialog as follows:

An example for a non-modal dialog:

⚠️ The following code is in C ⚠️

 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”.

Implements

MessageDialogExt, DialogExt, GtkWindowExt, BinExt, ContainerExt, WidgetExt, glib::ObjectExt, BuildableExt, DialogExtManual, [GtkWindowExtManual][trait@crate::prelude::GtkWindowExtManual], ContainerExtManual, WidgetExtManual, BuildableExtManual

Implementations

Creates a new builder-pattern struct instance to construct MessageDialog objects.

This method returns an instance of MessageDialogBuilder which can be used to create MessageDialog objects.

Creates a new message dialog, which is a simple dialog with some text the user may want to see. When the user clicks a button a “response” signal is emitted with response IDs from ResponseType. See Dialog for more details.

parent

transient parent, or None for none

flags

flags

type_

type of message

buttons

set of buttons to use

message_format

printf()-style format string, or None

Returns

a new MessageDialog
