-the screen. It can contain controls and other windows.

\wxheading{Remarks}
-There are two kinds of dialog - {\it modal} and {\it modeless}. A modal dialog
-blocks program flow and user input on other windows until it is dismissed, whereas a modeless dialog behaves more
-like a frame in that program flow continues, and input on other windows is still possible.
-You specify the type of dialog with the {\bf wxDIALOG\_MODAL} and {\bf wxDIALOG\_MODELESS} window
-styles.
-
-A dialog may be loaded from a wxWindows resource file (extension {\tt wxr}), which may itself
-be created by Dialog Editor. For details,
-see \helpref{The wxWindows resource system}{resourceformats}, \helpref{wxWindows resource functions}{resourcefuncs} and
-the resource sample.
-
-An application can define an \helpref{OnCloseWindow}{wxwindowonclosewindow} handler for the
-dialog to respond to system close events.
+There are two kinds of dialog -- {\it modal}\ and {\it modeless}. A modal dialog
+blocks program flow and user input on other windows until it is dismissed,
+whereas a modeless dialog behaves more like a frame in that program flow
+continues, and input in other windows is still possible. To show a modal dialog
+you should use the \helpref{ShowModal}{wxdialogshowmodal} method while to show
+a dialog modelessly you simply use \helpref{Show}{wxdialogshow}, just as with
+frames.
+
+Note that the modal dialog is one of the very few examples of
+wxWindow-derived objects which may be created on the stack and not on the heap.
+In other words, although this code snippet:
+
+\begin{verbatim}
+ void AskUser()
+ {
+ MyAskDialog *dlg = new MyAskDialog(...);
+ if ( dlg->ShowModal() == wxID_OK )
+ ...
+ //else: dialog was cancelled or some another button pressed
+
+ dlg->Destroy();
+ }
+\end{verbatim}
+
+works, you can also achieve the same result by using a simpler code fragment
+below:
+
+\begin{verbatim}
+ void AskUser()
+ {
+ MyAskDialog dlg(...);
+ if ( dlg.ShowModal() == wxID_OK )
+ ...
+
+ // no need to call Destroy() here
+ }
+\end{verbatim}
+
+An application can define a \helpref{wxCloseEvent}{wxcloseevent} handler for
+the dialog to respond to system close events.

Changes the dialog's colour to conform to the current settings (Windows only).
Add an event table entry for your dialog class if you wish the behaviour
to be different (such as keeping a user-defined
-background colour). If you do override this function, call \helpref{wxWindow::OnSysColourChanged}{wxwindowonsyscolourchanged} to

+is activated, otherwise \texttt{wxID\_OK} button is activated if present.
+Another possible special value for \arg{id} is \texttt{wxID\_NONE} meaning that
