\section{\class{wxDialog}}\label{wxdialog}
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 usually used to allow the user to make some choice or to answer a question.
+is often used to allow the user to make some choice or to answer a question.
+
+
+\subsection{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).

+
+The sizer lays out the buttons in a manner appropriate to the platform.

-
-The default handler for the wxID\_CANCEL identifier.

-\func{void}{OnOK}{\param{wxCommandEvent\& }{event}}
+\func{void}{SetAffirmativeId}{\param{int }{id}}
-The default handler for the wxID\_OK identifier.
+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.
-\wxheading{Remarks}
+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.
-The function calls
-\rtfsp\helpref{wxWindow::Validate}{wxwindowvalidate}, then \helpref{wxWindow::TransferDataFromWindow}{wxwindowtransferdatafromwindow}.
-If this returns true, the function either calls {\bf EndModal(wxID\_OK)} if the dialog is modal, or
-sets the return value to wxID\_OK and calls {\bf Show(false)} if the dialog is modeless.
+By default, the affirmative id is wxID\_OK.

-The default handler for wxEVT\_SYS\_COLOUR\_CHANGED.
+\func{void}{SetEscapeId}{\param{int }{id}}
-\wxheading{Parameters}
+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.
-\docparam{event}{The colour change event.}
+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.
