NAME and DESCRIPTION.
-\section{Memory models and memory allocation}\label{memorymodels}
-
-Under UNIX, memory allocation isn't a problem. Under Windows, the only
-really viable way to go is to use the large model, which uses the global
-heap instead of the local heap for memory allocation. Unless more than
-one read-write data segment is used,% (see \helpref{large data}{largedata}
-large model programs may still have multiple instances under MS
-C/C++ 7. Microsoft give the following guidelines for producing
-multiple-instance large model programs:
-
-\begin{itemize}\itemsep=0pt
-\item Do not use {\tt /ND} to name extra data segments unless the segment is READONLY.
-\item Use the .DEF file to mark extra data segments READONLY.
-\item Do not use \_\_far or FAR to mark data items.
-\item Use {\tt /PACKDATA} to combine data segments.
-\item Use {\tt /Gt65500 /Gx} to force all data into the default data segment.
-\end{itemize}
-
-Even with the single-instance limitation, the productivity benefit is
-worth it in the majority of cases. Note that some other multi-platform
-class libraries also have this restriction. (If more than one instance
-really is required, create several copies of the program with different
-names.)
-
-Having chosen the large model, just use C++ `new', `delete' (and if
-necessary `malloc' and `free') in the normal way. The only restrictions
-now encountered are a maximum of 64 KB for a single program segment and
-for a single data item, unless huge model is selected.
-
-For Borland users, use the data threshold switch, and the following is
-also recommended:
-
-\begin{itemize}\itemsep=0pt
-\item Check ``Automatic Far Data Segments"
-\item Check ``Put Constant Strings into Code Segment"
-\end{itemize}
-
-See also the Frequently Asked Questions document for further details
-on using Borland with wxWindows.

\subsection{Allocating and deleting wxWindows objects}
In general, classes derived from wxWindow must dynamically allocated
all of its children and descendants will be automatically deleted,
so you don't need to delete these descendants explicitly.
-Don't statically create a window unless you know that the window
-cannot be deleted dynamically. Modal dialogs, such as those used
-in the {\tt dialogs} sample, can usually be created statically,
-if you know that the OK or Cancel button does not destroy the dialog.
+When deleting a frame or dialog, use {\bf Destroy} rather than {\bf delete} so
+that the wxWindows delayed deletion can take effect. This waits until idle time
+(when all messages have been processed) to actually delete the window, to avoid
+problems associated with the GUI sending events to deleted windows.
-Most drawing objects, such as wxPen, wxBrush, wxFont, and wxBitmap, should be
-created dynamically. They are cleaned up automatically on program exit.
-wxColourMap is an exception to this rule (currently). In particular,
-do not attempt to create these objects globally before OnInit() has a chance
-to be called, because wxWindows might not have done essential internal initialisation
-(including creation of lists containing all instances of wxPen, wxBrush etc.)
+Don't create a window on the stack, because this will interfere
+with delayed deletion.
If you decide to allocate a C++ array of objects (such as wxBitmap) that may
be cleaned up by wxWindows, make sure you delete the array explicitly
Beware of deleting objects such as a wxPen or wxBitmap if they are still in use.
Windows is particularly sensitive to this: so make sure you
-make calls like wxDC::SetPen(NULL) or wxDC::SelectObject(NULL) before deleting
+make calls like wxDC::SetPen(wxNullPen) or wxDC::SelectObject(wxNullBitmap) before deleting
a drawing object that may be in use. Code that doesn't do this will probably work
fine on some platforms, and then fail under Windows.
-\section{Dynamic Link Libraries}
-
-wxWindows may be used to produce DLLs which run under MS Windows. Note that
-this is not the same thing as having wxWindows as a DLL, which is not
-currently possible. For Microsoft C++, use the makefile with the argument DLL=1 to produce
-a version of the wxWindows library which may be used in a DLL application.
-There is a bug in Microsoft C++ which makes the compiler complain about returned floats,
-which goes away when the {\tt /Os} option is used, which is why that flag is
-set in the makefile.
-
-For making wxWindows as a Sun dynamic library, there are comments in the
-UNIX makefile for the appropriate flags for AT\&T C++. Sorry, I haven't
-investigated the flags needed for other compilers.
-
\section{Conditional compilation}
One of the purposes of wxWindows is to reduce the need for conditional
features (such as metafile use under MS Windows). The following identifiers
may be used for this purpose, along with any user-supplied ones:
-\begin{itemize}
-\item {\tt wx\_x} - for code which should work under any X toolkit
-\item {\tt wx\_motif} - for code which should work under Motif only
-\item {\tt wx\_msw} - for code which should work under Microsoft Windows only
-\item {\tt wx\_xt} - for code which should work under Xt only
-\end{itemize}
-
-For example:
+{\bf GUIs:}
\begin{verbatim}
- ...
-#ifdef wx_x
- (void)wxMessageBox("Sorry, metafiles not available under X.");
-#endif
-#ifdef wx_msw
- wxMetaFileDC dc;
- DrawIt(dc);
- wxMetaFile *mf = dc.Close();
- mf->SetClipboard();
- delete mf;
-#endif
- ...
+__X__ any X, but not GTK
+__WXMOTIF__ Motif
+__WXGTK__ GTK
+__WXMSW__ Any Windows
+__MAC__ MacOS
+__UNIX__ any Unix
+__WIN95__ GUI for Windows 95 and above; NT 4.0 and above.
+__WIN32__ WIN32 API
+__NT__ Windows NT
+__CURSES__ CURSES
\end{verbatim}
-\section{Building on-line help}
+{\bf OSes:}
-wxWindows has its own help system from version 1.30: wxHelp. It can be
-used to view the wxWindows class library reference, and also to provide
-on-line help for your wxWindows applications. The API, made accessible
-by including {\tt wx\_help.h}, allows you to load files and display
-specific sections, using DDE to communicate between the application and
-wxHelp.
+\begin{verbatim}
+__HPUX__
+__SVR4__
+__SYSV__
+__LINUX__
+__SGI__
+__ULTRIX__
+__BSD__
+__VMS__
+__SUN__ Any Sun
+__SUNOS__
+__SOLARIS__
+__ALPHA__
+__AIX__
+__DATA_GENERAL__
+__OSF__
+__FREEBSD__
+\end{verbatim}
-wxHelp files can be marked up by hand from ASCII files within wxHelp,
-or may be generated from other files, as is the case with the wxWindows
-documentation.
+{\bf Compilers:}
-It is possible to use the platform-specific help
-system (e.g. WinHelp) instead of wxHelp.
+\begin{verbatim}

+__BORLANDC__ Borland C++
+__WATCOMC__ Watcom C++
+__SYMANTECC__ Symantec C++
+__VISUALC__ VC++
+__SUNCC__
+\end{verbatim}
+
+{\bf wxWindows modes:}
-See {\tt install.txt}, the wxHelp documentation (in {\tt
-utils/wxhelp/docs}) and \helpref{wxHelp}{wxhelp} for further details.
+\begin{verbatim}
+__WXDEBUG__ usage: #ifdef __DEBUG__ (=> debug mode, else => release)
+\end{verbatim}
\section{C++ issues}
-There are cases where a C++ program will compile and run fine under one
-environment, and then fail to compile using a different compiler. Some
-caveats are given below, from experience with the GNU C++ compiler (GCC)
-and MS C/C++ compiler version 7.
+The following documents some miscellaneous C++ issues.
\subsection{Templates}
-wxWindows does not use templates for two main reasons: one, it is a
-notoriously unportable feature, and two, the author is irrationally
-suspicious of them and prefers to use casts. More compilers are
-now implementing templates, and so it will probably be safe to use
-them soon without fear of portability problems.
+wxWindows does not use templates since it is a notoriously unportable feature.
\subsection{Precompiled headers}

considerably. For this reason, you will find (in the common
X and Windows parts of the library) conditional
-compilation that under UNIX, includes a minimal set of headers;

the optimal compilation for each compiler, although it is
