-Enhancements for wxWidgets 3.0
-==============================
-
-This table contains the brief summary of the issues below. Priority and
-Difficulty are values from 1 to 10 with 1 being the least important/difficult
-and 10 the most.

-Native RTTI 7 7
-TRUE/true 9 1

-C++ Features
-============
-
-- Namespaces:
- We want to have all wxWidgets identifiers in "wx" namespace but provide
- typedefs/#defines for backwards compatibility. This can be done easily
- for the classes and the only real problem are the enums as they would
- all have to be duplicated at both the global scope (with "wx" prefix) and
- in wx namespace (without it)
-
-- STLization
- This involves providing optional wxString implementation using std::string
- and doing the same for all our containers with the exception of wxHashMap
- which should simply be rewritten using templates (but keeping the old
- version for backwards compatibility -- ideally wx 3.0 would still be usable
- without templates, even if not all of its features would be available then)
-
-- Exceptions
- We are not going to use exceptions in wxWidgets itself but our code should
- become exception safe. This is a very difficult task as it means that no
- resource allocations (including memory, files, whatever) should be done
- without using a smart pointer-like object to store the result as it is the
- only way to prevent resource leaks in presence of exceptions
-
-- Real RTTI
- Optionally use the real RTTI instead of wx emulation of it. Keep the
- current stuff for backwards compatibility.
-
-- Complete replacing TRUE/FALSE with true/false
- Trivial
-
-
-Core
-====
-
-- use wxEventLoop in all builds
- wxApp and wxDialog should use wxEventLoop objects (the exact class can be
- customized by user code by overriding some wxApp::CreateEventLoop())
- instead of duplicating the same code
-
-- remove wxCOMPATIBILITY
- wxDEPRECATED() should be used with everything inside WXWIN_COMPATIBILITY_2_4.
- The stuff inside WXWIN_COMPATIBILITY_2_6 probably should not be deprecated
- (yet?) because this would give thousands of warnings for the existing code.
- Exception is api documented as obsolete in 2.6 release already.
-
-- Modularization/Build System
- Candidates for components:
- + contrib widgets (and maybe some of the ones currently in the core)
- + wxHTML
- + network stuff
- + printing (?)
- + ODBC classes
- + ...
-
-- Project File Generation
- We need a (GUI) tool to generate the project/makefiles for all supported
- platforms/compilers. Not sure if it should be used for the library itself
- (would be nice to have something like "make menuconfig" for Linux kernel
- which allows you to navigate easily among all of the configure/setup.h
- options but there is a problem with distributing such tool as it can't be
- compiled by the user because it is needed before the library is built) but
- we definitely need it for the users makefiles.
-
-- Properties/Member-Metadata, 2-Step Init with virtual create
-
-- Tidy code and add comments to headers (possibly in
- Doxygen/Javadoc style)
-
-
-Documentation
-=============
-
-- The possibility of moving doc into header files with tool
- support.
-- Detailed review of doc accuracy.
-- wxDC : Precise definition of default/initial state.
-- wxDC : Pixelwise definition of operations (e.g. last point of a
- line not drawn).
-- Events:
- For all controls state clearly when calling a member function results in an
- event being generated and when it doesn't.
-- Update the coding standards guide
-
-
-wxEvents
-========
-
-- Change Idle Handling
- Current Implementation is using too many CPU cycles
-
-- Loose Coupling Event-Source Event-Sink
- kind of the NextStep/C# very performant coupling, exposing events via
- Metadata
-
-- Add Lazy Init of Eventtables
-
-
-Modules/Plugins
-===============
-
-Architecture
-------------
-
-We aim to arrive at a lazy initialization of modules only when they are first
-needed. Dependency information between modules is needed. Dynamic Plug-In
-loading and unloading must be compatible with that.
-
-
-wxUniversal
-===========
-
-- Renderers within native ports.
-
-
-wxPrinting
-==========
-
-- Page preflighting capabilities in order to determine number
- of pages.
-- Preview UI enhancement.
-
-
-wxStaticBox
-===========
-
-Hide the platform problems (GTK: 'children' must be siblings) in encapsulation
-in order to avoid problems on ports where the hierarchy must be
-'correct'.
-
-
-Removal of old code
-===================
-
-In addition to wxCOMPATIBILITY code:
-
-- contrib/src/mmedia
-- contrib/src/applet?
-- Dialog Editor
-
-wxMiscellaneous
-===============
-
-- wxDC Support for point to char-position with text rendering
-- wxLocale Extension (eg Currency)
-- wxStreams review
-- wxURL?
-- a way to tell wxWidgets to check for any non-portable usage,
- for a given set of platforms. Sometimes you want to be able
- to get away with non-portable usage, and sometimes not.
- This is probably way too time-consuming to implement.
-- In headers, don't silently omit contents if the features for this
- header is switched off. Instead, emit an error message.
-- Implement native tree view and colour dialog in wxGTK.
-- Better way to specify About, Preferences menu ids under wxMac.
-- Must be able to portably specify relaying out a frame after the toolbar
- has been destroyed or recreated. On wxMSW, this is done in
- ~wxToolBar. On wxGTK, in SetToolBar. In wxMac, not at all,
- but sending a wxSizeEvent will do it.
-- Need wxRect wxToolBar::GetToolRect(int id) or similar so we can
- align a popup menu with a toolbar button.
-- wxMac font selector dialog is the generic font selector -
- horrible.
-- No Append(wxArrayString&) for wxChoice and wxComboBox in wxGTK.
- Probably other functions too. Consider adding Insert to
- these classes, as per the patch on SF.
-- Rewrite wxFileHistory using wxString and wxArrayString, and
- put in separate file.
-- Add wxArrayString methods to wxTextValidator and any other
- class that needs them.
-- Add wxNotebook::GetTabRect or similar so we can estimate
- page size better in wxNotebookBase::CalcSizeFromPage.
-- Add function to clear all wxNotebook tabs without
- destroying the pages.
-- Add individual setters to wxScrollBar and other classes
- that use a combined setter.
-- Remove traces of old resource system from wxWizard.
-- Have wxDirCtrl as alias for wxGenericDirCtrl.
-- Allow instant reaction to left-up in a wxGrid cell
- (extend editor API) to work around bad checkbox
- behaviour (click, click, click, click away...) and
- reduce checkbox size on non-Windows platforms.
-- Add wxNotebook::HitTest for non-Windows platforms.
-- Implement rebar for all platforms. This will help us
- get closer to native look and feel, e.g. the gradient
- shadow on XP toolbars.
