-
-These are a few of the major differences between versions 1.xx and 2.0.
-
-Removals:
-
-\begin{itemize}\itemsep=0pt
-\item XView is no longer supported;
-\item all controls (panel items) no longer have labels attached to them;
-\item wxForm has been removed;
-\item wxCanvasDC, wxPanelDC removed (replaced by wxClientDC, wxWindowDC, wxPaintDC which
-can be used for any window);
-\item wxMultiText, wxTextWindow, wxText removed and replaced by wxTextCtrl;
-\item classes no longer divided into generic and platform-specific parts, for efficiency.
-\end{itemize}
-
-Additions and changes:
-
-\begin{itemize}\itemsep=0pt
-\item class hierarchy changed, and restrictions about subwindow nesting lifted;
-\item header files reorganised to conform to normal C++ standards;
-\item classes less dependent on each another, to reduce executable size;
-\item wxString used instead of char* wherever possible;
-\item the number of separate but mandatory utilities reduced;
-\item the event system has been overhauled, with
-virtual functions and callbacks being replaced with MFC-like event tables;
-\item new controls, such as wxTreeCtrl, wxListCtrl, wxSpinButton;
-\item less inconsistency about what events can be handled, so for example
-mouse clicks or key presses on controls can now be intercepted;
-\item the status bar is now a separate class, wxStatusBar, and is
-implemented in generic wxWindows code;
-\item some renaming of controls for greater consistency;
-\item wxBitmap has the notion of bitmap handlers to allow for extension to new formats
-without ifdefing;
-\item new dialogs: wxPageSetupDialog, wxFileDialog, wxDirDialog,
-wxMessageDialog, wxSingleChoiceDialog, wxTextEntryDialog;
-\item GDI objects are reference-counted and are now passed to most functions
-by reference, making memory management far easier;
-\item wxSystemSettings class allows querying for various system-wide properties
-such as dialog font, colours, user interface element sizes, and so on;
-\item better platform look and feel conformance;
-\item toolbar functionality now separated out into a family of classes with the
-same API;
-\item device contexts are no longer accessed using wxWindow::GetDC - they are created
-temporarily with the window as an argument;
-\item events from sliders and scrollbars can be handled more flexibly;
-\item the handling of window close events has been changed in line with the new
-event system;
-\item the concept of {\it validator} has been added to allow much easier coding of
-the relationship between controls and application data;
-\item the documentation has been revised, with more cross-referencing.
-\end{itemize}
-
-Platform-specific changes:
-

-\section{Libraries}
+\section{Libraries}\label{libraries}

 
 

-The GTK and Motif ports of wxWindow can create either a static library or a shared
-library on most Unix or Unix-like systems. The static library is called libwx\_gtk.a
-and libwx\_motif.a whereas the name of the shared library is dependent on the
-system it is created on and the version you are using. The library name for the
-GTK version of wxWindows 2.2 on Linux and Solaris will be libwx\_gtk-2.2.so.0.0.0,
-on HP-UX, it will be libwx\_gtk-2.2.sl, on AIX just libwx\_gtk.a etc.
+Most ports of wxWidgets can create either a static library or a shared
+library. wxWidgets can also be built in multilib and monolithic variants.
+See the \helpref{libraries list}{librarieslist} for more
+information on these.

 
 

-Under Windows, use the library wx.lib (release) or wxd.lib (debug) for stand-alone Windows
-applications, or wxdll.lib (wxdlld.lib) for creating DLLs.

-\section{Makefiles}
+\section{Makefiles}\label{makefiles}
+
+On Microsoft Windows, wxWidgets has a different set of makefiles for each
+compiler, because each compiler's 'make' tool is slightly different.
+Popular Windows compilers that we cater for, and the corresponding makefile
+extensions, include: Microsoft Visual C++ (.vc), Borland C++ (.bcc),
+OpenWatcom C++ (.wat) and MinGW/Cygwin (.gcc). Makefiles are provided
+for the wxWidgets library itself, samples, demos, and utilities.
+
+On Linux, Mac and OS/2, you use the 'configure' command to
+generate the necessary makefiles. You should also use this method when
+building with MinGW/Cygwin on Windows.

 
 

-At the moment there is no attempt to make Unix makefiles and
-PC makefiles compatible, i.e. one makefile is required for
-each environment. The Unix ports use a sophisticated system based
-on the GNU autoconf tool and this system will create the
-makefiles as required on the respective platform. Although the
-makefiles are not identical in Windows, Mac and Unix, care has
-been taken to make them relatively similar so that moving from
-one platform to another will be painless.
+We also provide project files for some compilers, such as
+Microsoft VC++. However, we recommend using makefiles
+to build the wxWidgets library itself, because makefiles
+can be more powerful and less manual intervention is required.

 
 

-Sample makefiles for Unix (suffix .unx), MS C++ (suffix .DOS and .NT), Borland
-C++ (.BCC and .B32) and Symantec C++ (.SC) are included for the library, demos
-and utilities.
+On Windows using a compiler other than MinGW/Cygwin, you would
+build the wxWidgets library from the build/msw directory
+which contains the relevant makefiles.

 
 

-The controlling makefile for wxWindows is in the MS-Windows
-directory {\tt src/msw} for the different Windows compiler and
-in the build directory when using the Unix ports. The build
-directory can be chosen by the user. It is the directory in
-which the "configure" script is run. This can be the normal
-base directory (by running {\tt ./configure} there) or any other
-directory (e.g. {\tt ../configure} after creating a build-directory
-in the directory level above the base directory).
+On Windows using MinGW/Cygwin, and on Unix, MacOS X and OS/2, you invoke
+'configure' (found in the top-level of the wxWidgets source hierarchy),
+from within a suitable empty directory for containing makefiles, object files and
+libraries.

 
 

-Please see the platform-specific {\tt install.txt} file for further details.

-\section{wxHelp}\label{wxhelp}
-
-wxHelp is a stand-alone program, written using wxWindows,
-for displaying hypertext help. It is necessary since not all target
-systems (notably X) supply an adequate
-standard for on-line help. wxHelp is modelled on the MS Windows help
-system, with contents, search and browse buttons, but does not reformat
-text to suit the size of window, as WinHelp does, and its input files
-are uncompressed ASCII with some embedded font commands and an .xlp
-extension. Most wxWindows documentation (user manuals and class
-references) is supplied in wxHelp format, and also in Windows Help
-format. The wxWindows 2.0 project will presently use an HTML widget
-in a new and improved wxHelp implementation, under X.
-
-Note that an application can be programmed to use Windows Help under
-MS Windows, and wxHelp under X. An alternative help viewer under X is
-Mosaic, a World Wide Web viewer that uses HTML as its native hypertext
-format. However, this is not currently integrated with wxWindows
-applications.
-
-wxHelp works in two modes---edit and end-user. In edit mode, an ASCII
-file may be marked up with different fonts and colours, and divided into
-sections. In end-user mode, no editing is possible, and the user browses
-principally by clicking on highlighted blocks.
-
-When an application invokes wxHelp, subsequent sections, blocks or
-files may be viewed using the same instance of wxHelp since the two
-programs are linked using wxWindows interprocess communication
-facilities. When the application exits, that application's instance of
-wxHelp may be made to exit also.  See the {\bf wxHelpControllerBase} entry in the
-reference section for how an application controls wxHelp.

-\section{wxTreeLayout}
-
-This is a simple class library for drawing trees in a reasonably pretty
-fashion. It provides only minimal default drawing capabilities, since
-the algorithm is meant to be used for implementing custom tree-based
-tools.
-
-Directed graphs may also be drawn using this library, if cycles are
-removed before the nodes and arcs are passed to the algorithm.
-
-Tree displays are used in many applications: directory browsers,
-hypertext systems, class browsers, and decision trees are a few
-possibilities.
-
-See the separate manual and the directory utils/wxtree.
-
-\section{wxGraphLayout}
-
-The wxGraphLayout class is based on a tool called `graphplace' by Dr.
-Jos T.J. van Eijndhoven of Eindhoven University of Technology. Given a
-(possibly cyclic) directed graph, it does its best to lay out the nodes
-in a sensible manner. There are many applications (such as diagramming)
-where it is required to display a graph with no human intervention. Even
-if manual repositioning is later required, this algorithm can make a good
-first attempt.

-technique is to just make arbitrary changes to the code until something
-different happens. You may have an intuition why a change will make a difference;
-otherwise, just try altering the order of code, comment lines out, anything
-to get over an impasse. Obviously, this is usually a last resort.
