\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}).
-
-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 on other windows is still possible. To show a modal dialog
+you should use \helpref{ShowModal}{wxdialogshowmodal} method while to show
+dialog modelessly you simply use \helpref{Show}{wxdialogshow}, just as with the
+frames.
+
+Note that the modal dialogs are 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 an \helpref{wxCloseEvent}{wxcloseevent} handler for
+the dialog to respond to system close events.

\wxheading{Remarks}
Note that in Windows, iconization has no effect since dialog boxes cannot be
iconized. However, applications may need to explicitly restore dialog
boxes under Motif which have user-iconizable frames, and under Windows
-calling {\tt Iconize(FALSE)} will bring the window to the front, as does
-\rtfsp{\tt Show(TRUE)}.

\membersection{wxDialog::IsIconized}\label{wxdialogisiconized}
\constfunc{bool}{IsIconized}{\void}
-Returns TRUE if the dialog box is iconized. Windows only.
+Returns true if the dialog box is iconized. Windows only.

\membersection{wxDialog::OnCharHook}\label{wxdialogoncharhook}
This member is called to allow the window to intercept keyboard events
before they are processed by child windows.

The function either calls {\bf EndModal(wxID\_CANCEL)} if the dialog is modal, or

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
+background colour). If you do override this function, call wxEvent::Skip to
propagate the notification to child windows and controls.

+{\bf NB:} This function is deprecated and doesn't work for all ports, just use
+\helpref{ShowModal}{wxdialogshowmodal} to show a modal dialog instead.

Allows the programmer to specify whether the dialog box is modal (wxDialog::Show blocks control
until the dialog is hidden) or modeless (control returns immediately).
