A dialog box is a window with a title bar and sometimes a system menu, which
can be moved around the screen. It can contain controls and other windows and

+is often used to allow the user to make some choice or to answer a question.

+
+\wxheading{Dialog Buttons}
+
+The dialog usually contains either a single button allowing to close the
+dialog or two buttons, one accepting the changes and the other one discarding
+them (such button, if present, is automatically activated if the user presses
+the \texttt{"Esc"} key). By default, buttons with the standard \texttt{wxID\_OK}
+and \texttt{wxID\_CANCEL} identifiers behave as expected. Starting with
+wxWidgets 2.7 it is also possible to use a button with a different identifier
+instead, see \helpref{SetAffirmativeId}{wxdialogsetaffirmativeid} and
+\helpref{SetEscapeId}{wxdialogsetescapeid}.
+
+Also notice that the \helpref{CreateButtonSizer()}{wxdialogcreatebuttonsizer}
+should be used to create the buttons appropriate for the current platform and
+positioned correctly (including their order which is platform-dependent).

+This function uses \helpref{CreateStdDialogButtonSizer}{wxdialogcreatestddialogbuttonsizer}
+internally for most platforms but doesn't create the sizer at all for the
+platforms with hardware buttons (such as smartphones) for which it sets up the
+hardware buttons appropriately and returns \NULL, so don't forget to test that
+the return value is valid before using it.

\func{void}{SetAffirmativeId}{\param{int }{id}}
-Sets the identifier to be used when the user presses an OK button in a PocketPC titlebar.
-By default, this is wxID\_OK.
+Sets the identifier to be used as OK button. When the button with this
+identifier is pressed, the dialog calls \helpref{Validate}{wxwindowvalidate}
+and \helpref{wxWindow::TransferDataFromWindow}{wxwindowtransferdatafromwindow}
+and, if they both return \true, closes the dialog with \texttt{wxID\_OK} return
+code.
+
+Also, when the user presses a hardware OK button on the devices having one or
+the special OK button in the PocketPC title bar, an event with this id is
+generated.
+
+By default, the affirmative id is wxID\_OK.

\func{void}{SetEscapeId}{\param{int }{id}}
-Sets the identifier to be used when the user presses \texttt{\textsc{ESC}}
-button in the dialog. By default, this is \texttt{wxID\_ANY} meaning that
-the first suitable button is used: if there a \texttt{wxID\_CANCEL} button, it
-is activated, otherwise \texttt{wxID\_OK} button is activated if present.
-Another possible special value for \arg{id} is \texttt{wxID\_NONE} meaning that
-\texttt{\textsc{ESC}} presses should be ignored. If another value is given, it
+Sets the identifier of the button which should work like the standard
+\texttt{\textsc{Cancel}} button in this dialog. When the button with this id is
+clicked, the dialog is closed. Also, when the user presses \texttt{\textsc{ESC}}
+key in the dialog or closes the dialog using the close button in the title bar,
+this is mapped to the click of the button with the specified id.
+
+By default, the escape id is the special value \texttt{wxID\_ANY} meaning that
+\texttt{wxID\_CANCEL} button is used if it's present in the dialog and
+otherwise the button with \helpref{GetAffirmativeId()}{wxdialoggetaffirmativeid}
+is used. Another special value for \arg{id} is \texttt{wxID\_NONE} meaning that
+\texttt{\textsc{ESC}} presses should be ignored. If any other value is given, it
is interpreted as the id of the button to map the escape key to.
