pub struct MessageDialog { /* private fields */ }

👎Deprecated:

Since 1.6

Available on crate feature v1_2 only.

Use AlertDialog.

## Accessibility

[`MessageDialog`][crate::MessageDialog] uses the [enum@Gtk.AccessibleRole.dialog] role.

## Properties


#### `body`
 The body text of the dialog.

Readable | Writable


#### `body-use-markup`
 Whether the body text includes Pango markup.

See `parse_markup()`.

Readable | Writable


#### `close-response`
  or with a system action.

It doesn't have to correspond to any of the responses in the dialog.

The default close response is `close`.

Readable | Writable


#### `default-response`
 The response ID of the default response.

The button corresponding to this response will be set as the default widget
of the dialog.

If not set, the default widget will not be set, and the last added response
will be focused by default.

See [`default-widget`][struct@crate::gtk::Window#default-widget].

Readable | Writable


#### `extra-child`
 The child widget.

Displayed below the heading and body.

Readable | Writable


#### `heading`
 The heading of the dialog.

Readable | Writable


#### `heading-use-markup`
 Whether the heading includes Pango markup.

See `parse_markup()`.

Readable | Writable
<details><summary><h4>Window</h4></summary>


#### `application`
 The [`gtk::Application`][crate::gtk::Application] associated with the window.

The application will be kept alive for at least as long as it
has any windows associated with it (see g_application_hold()
for a way to keep it alive without windows).

Normally, the connection between the application and the window
will remain until the window is destroyed, but you can explicitly
remove it by setting the this property to `NULL`.

Readable | Writable


#### `child`
 The child widget.

Readable | Writable


#### `decorated`
 Whether the window should have a frame (also known as *decorations*).

Readable | Writable


#### `default-height`
 The default height of the window.

Readable | Writable


#### `default-widget`
 The default widget.

Readable | Writable


#### `default-width`
 The default width of the window.

Readable | Writable


#### `deletable`
 Whether the window frame should have a close button.

Readable | Writable


#### `destroy-with-parent`

Readable | Writable


#### `display`
 The display that will display this window.

Readable | Writable


#### `focus-visible`

This property is maintained by GTK based on user input
and should not be set by applications.

Readable | Writable


#### `focus-widget`
 The focus widget.

Readable | Writable


#### `fullscreened`
 Whether the window is fullscreen.

Setting this property is the equivalent of calling
[`GtkWindowExtManual::fullscreen()`][crate::gtk::prelude::GtkWindowExtManual::fullscreen()] or [`GtkWindowExtManual::unfullscreen()`][crate::gtk::prelude::GtkWindowExtManual::unfullscreen()];
either operation is asynchronous, which means you will need to
connect to the ::notify signal in order to know whether the
operation was successful.

Readable | Writable


#### `gravity`
 The gravity to use when resizing the window programmatically.

Gravity describes which point of the window we want to keep
fixed (meaning that the window will grow in the opposite direction).
For example, a gravity of `GTK_WINDOW_GRAVITY_TOP_RIGHT` means that we
want the to fix top right corner of the window.

Readable | Writable


#### `handle-menubar-accel`

menubars.

Readable | Writable


#### `hide-on-close`
 If this window should be hidden instead of destroyed when the user clicks

Setting this property is the equivalent of calling
[`GtkWindowExtManual::maximize()`][crate::gtk::prelude::GtkWindowExtManual::maximize()] or [`GtkWindowExtManual::unmaximize()`][crate::gtk::prelude::GtkWindowExtManual::unmaximize()];
either operation is asynchronous, which means you will need to
connect to the ::notify signal in order to know whether the
operation was successful.

## Signals


#### `response`
  or with a system
action, @response will be set to the value of
[`close-response`][struct@crate::MessageDialog#close-response].

Detailed
<details><summary><h4>Window</h4></summary>


#### `activate-default`
  key.

Action


#### `activate-focus`
 .

Action


#### `close-request`
 Emitted when the user clicks on the close button of the window.




#### `enable-debugging`
 .

Action


#### `force-close`
 Emitted when the compositor has decided to eliminate a window.

@window *has* to be in a hidden state after this signal was handled.




#### `keys-changed`
 Emitted when the set of accelerators or mnemonics that
are associated with the window changes.


</details>
<details><summary><h4>Widget</h4></summary>


#### `destroy`
 Signals that all holders of a reference to the widget should release
the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.




#### `direction-changed`
 Emitted when the text direction of a widget changes.




#### `hide`
 Emitted when @widget is hidden.




#### `keynav-failed`
 Emitted if keyboard navigation fails.

See [`WidgetExtManual::keynav_failed()`][crate::gtk::prelude::WidgetExtManual::keynav_failed()] for details.




#### `map`
 Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with
[`visible`][struct@crate::gtk::Widget#visible]) and all its parents up to the toplevel widget
are also visible.

The `::map` signal can be used to determine whether a widget will be drawn,
for instance it can resume an animation that was stopped during the
emission of [`unmap`][struct@crate::gtk::Widget#unmap].




#### `mnemonic-activate`
 Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling
is false, or just makes @widget grab focus if @group_cycling is true.




#### `move-focus`
  to move backward.

Action


#### `query-tooltip`
 s tooltip is about to be shown.

This happens when the [`has-tooltip`][struct@crate::gtk::Widget#has-tooltip] property
is true and the hover timeout has expired with the cursor hovering
above @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine
whether a tooltip should be shown for @widget. If this is the case
true should be returned, false otherwise. Note that if @keyboard_mode
is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore
destined function calls.




#### `realize`
 Emitted when @widget is associated with a `GdkSurface`.

This means that [`WidgetExtManual::realize()`][crate::gtk::prelude::WidgetExtManual::realize()] has been called
or the widget has been mapped (that is, it is going to be drawn).




#### `show`
 Emitted when @widget is shown.




#### `state-flags-changed`
 Emitted when the widget state changes.

See [`WidgetExtManual::state_flags()`][crate::gtk::prelude::WidgetExtManual::state_flags()].




#### `unmap`
 Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the
toplevel widget have been set as hidden.

As `::unmap` indicates that a widget will not be shown any longer,
it can be used to, for example, stop an animation on the widget.




#### `unrealize`
 Emitted when the `GdkSurface` associated with @widget is destroyed.

This means that [`WidgetExtManual::unrealize()`][crate::gtk::prelude::WidgetExtManual::unrealize()] has been called
or the widget has been unmapped (that is, it is going to be hidden).
