<title>Description</title>
<para>Dialog boxes are a convenient way to prompt the user for a small
amount of input, e.g. to display a message, ask a question, or anything
else that does not require extensive effort on the user's part. Dialogs
are organized as a window split vertically. The top section is a <link
linkend="class-gtkvbox"><classname>gtk.VBox</classname></link>, and is
where widgets such as a <link
linkend="class-gtklabel"><classname>gtk.Label</classname></link> or a
<link linkend="class-gtkentry"><classname>gtk.Entry</classname></link>
should be packed. The bottom area is known as the action_area which is
generally used for packing buttons into the dialog which may perform
functions such as cancel, ok, or apply. The two areas are separated by a
<link
linkend="class-gtkhseparator"><classname>gtk.HSeparator</classname></link>.</para>
<para>The <link
linkend="class-gtkdialog"><classname>gtk.Dialog</classname></link> boxes
are created with a call to <link
linkend="constructor-gtkdialog"><methodname>gtk.Dialog</methodname></link>()
that sets the dialog title, some convenient flags, and adds simple
buttons. In a newly created dialog, the two primary areas of the window
can be accessed as the vbox and action_area attributes, as can be seen
from the example, below.</para>
<programlisting>
import gtk
label = gtk.Label("Nice label")
dialog = gtk.Dialog("My dialog",
None,
gtk.DIALOG_MODAL | gtk.DIALOG_DESTROY_WITH_PARENT,
(gtk.STOCK_CANCEL, gtk.RESPONSE_REJECT,
gtk.STOCK_OK, gtk.RESPONSE_ACCEPT))
dialog.vbox.pack_start(label)
label.show()
checkbox = gtk.CheckButton("Useless checkbox")
dialog.action_area.pack_end(checkbox)
checkbox.show()
response = dialog.run()
dialog.destroy()
</programlisting>
<para>A modal dialog (that is, one which freezes the
rest of the application from user input), can be created by passing the
<literal>gtk.DIALOG_MODAL</literal> flag to the <link
linkend="constructor-gtkdialog"><methodname>gtk.Dialog</methodname>()</link>
constructor or by calling <link
linkend="method-gtkwindow--set-modal"><methodname>set_modal</methodname>()</link>
on the dialog.</para>
<para>If you add buttons to <link
linkend="class-gtkdialog"><classname>gtk.Dialog</classname></link> using
<link
linkend="constructor-gtkdialog"><methodname>gtk.Dialog</methodname>()</link>,
<link
linkend="method-gtkdialog--add-button"><methodname>add_button</methodname>()</link>,
or <link
linkend="method-gtkdialog--add-action-widget"><methodname>add_action_widget</methodname>()</link>,
clicking the button will emit a signal called "response" with a response
ID that you specified. PyGTK will never assign a meaning to positive
response IDs; these are entirely user-defined. But for convenience, you
can use the pre-defined <xref linkend="gtk-response-type-constants"
endterm="gtk-response-type-constants-title"></xref> (these all have
values less than zero).</para>
<para>If a dialog receives a delete event, the "response" signal will be
emitted with a response ID of
<literal>gtk.RESPONSE_DELETE_EVENT</literal>.</para>
<para>If you want to block waiting for a dialog to return before
returning control flow to your code, you can call <link
linkend="method-gtkdialog--run"><methodname>run</methodname>()</link>. This
function enters a recursive main loop and waits for the user to respond
to the dialog, returning the response ID corresponding to the button the
user clicked.</para>

<para>Creates a new <link
linkend="class-gtkdialog"><classname>gtk.Dialog</classname></link> with the
title text specified by <parameter>title</parameter> (or
<literal>None</literal> for the default title; see <link
linkend="method-gtkwindow--set-title"><methodname>gtk.Window.set_title</methodname>()</link>)
and transient parent window specified by <parameter>parent</parameter> (or
<literal>None</literal> for none; see <link
linkend="method-gtkwindow--set-transient-for"><methodname>gtk.Window.set_transient_for</methodname>()</link>).
The <parameter>flags</parameter> argument can be used to make the dialog
modal (<literal>gtk.DIALOG_MODAL</literal>) and/or to have it destroyed
along with its transient parent
(<literal>gtk.DIALOG_DESTROY_WITH_PARENT</literal>) and/or remove the
separator (<literal>gtk.DIALOG_NO_SEPARATOR</literal>) (see the <xref
linkend="gtk-dialog-flag-constants"
endterm="gtk-dialog-flag-constants-title"></xref> for more
information). After <parameter>flags</parameter>, a tuple of button
text/response ID pairs should be listed, or <literal>None</literal> (the
default value) if no buttons are needed. The button text can be either a
stock ID such as <literal>gtk.STOCK_OK</literal>, or some arbitrary text. A
response ID can be any positive number, or one of the pre-defined <xref
linkend="gtk-response-type-constants"
endterm="gtk-response-type-constants-title"></xref>.</para>
<para>If the user clicks one of these dialog buttons, the <link
linkend="class-gtkdialog"><classname>gtk.Dialog</classname></link> will emit
the "response" signal with the corresponding response ID. If a <link
linkend="class-gtkdialog"><classname>gtk.Dialog</classname></link> receives
the "delete_event" signal, it will emit "response" with a response ID of
<literal>gtk.RESPONSE_DELETE_EVENT</literal>. However, destroying a dialog
does not emit the "response" signal; so be careful relying on "response"
when using the <literal>gtk.DIALOG_DESTROY_WITH_PARENT</literal> flag.
Buttons are added from left to right, so the first button in the list will
be the leftmost button in the dialog.</para>
<para>Here's a simple example:</para>
<programlisting>
dialog = gtk.Dialog("My dialog",
main_app_window,

<para>The <methodname>run</methodname>() method blocks in a recursive
main loop until the dialog either emits the "response" signal, or is
destroyed. If the dialog is destroyed, the <methodname>run</methodname>()
method returns <literal>gtk.RESPONSE_NONE</literal>; otherwise, it returns
the response ID from the "response" signal emission. Before entering the
recursive main loop, the <methodname>run</methodname>() method calls the
<link linkend="method-gtkwidget--show"><methodname>gtk.Widget.show</methodname>()</link>

dialog yourself.</para>
<para>During the <methodname>run</methodname>() method, the default
behavior of "delete_event" is disabled; if the dialog receives a
"delete_event", it will not be destroyed as windows usually are, and the
<methodname>run</methodname>() method will return
<literal>gtk.RESPONSE_DELETE_EVENT</literal>. Also, during the
<methodname>run</methodname>() method the dialog will be modal. You can
force the <methodname>run</methodname>() method to return at any time by
calling <link linkend="method-gtkdialog--response"><methodname>response</methodname>()</link>
to emit the "response" signal. Destroying the dialog during the
<methodname>run</methodname>() method is a very bad idea, because your
post-run code won't know whether the dialog was destroyed or not.</para>

<para>The <methodname>set_alternative_button_order</methodname>()

<para>By default, GTK+ dialogs use the button order advocated by the
Gnome Human Interface Guidelines with the affirmative button at the far
right, and the cancel button left of it. But the builtin GTK+ dialogs and
