-------------------------------------------------------------------
June 2005 Version 3.5b0
- Finished modificatons to work with .NET
- Created RSConstants.pas file, which includes basic types and constants.
Some of these constants and types were moved from IEConsts.pas and
FuzzyConsts.pas
Among the most important new types:
- TRSPointerType, which equals Pointer in Win32 and TObject in .NET
- TRSStringPointerType, which equals PChar in Win32 and String in .NET
- Modified most files to:
- Include RSDefines.inc
- Include RSConstants.pas
- Changed all methods and properties that use IUnknown interface to use
IInterface interface. Added IInterface interface for Delphi 5 support
- Changed all QueryInterface calls to use Supports functions.
- Removed reference counting code for .NET (not needed)
- Changed ToString properties to AsString and GetToString methods to
ToString to sync better with .NET (in which all objects have ToString
method)
- Changed Tag properties to be of TRSTag type (Win32=Integer;.NET=Variant)
- Introduced TxxxPersistent class to get around a delphi
compiler bug with class helpers (QC report #11019)
- Added inherited Creates calls to constructors for
compatibility with .NET
- Deleted AfterConstruction and BeforeDestruction methods (for .NET)
- Extracted icons from DCR files to create assembly bitmap files
for design-time icons in .NET
- Conditional compiled IUnknown methods (_addref, _release...)
because they are not needed with .NET
RiverSoftAVG Common Classes Library (GCollections package in Delphi 5, 6, and 7;
RSCommon package in Delphi 2005 (Win32) and
RiverSoftAVG.Common assembly in VCL.NET)
- Created TRSEncodedBits class (in RSEncodedBits.pas), a TBits descendant
with methods to encode/decode simple types into the TBits
- Modified InterfaceCollections.pas
- Modified TGInterfaceList to descend from TPersistent
- Modified descendants of TGInterfaceList to correctly override
methods
- Modified list classes to use a dynamic arrays instead of a
pointer to such an array (as used for Win32). The pointer
implementation was left for Win32 since it is faster than the
dynamic array implementation
- Changed DEMO out of memory errors to use standard Exception,
instead of EOutOfMemory exception, which (contrary to help file)
seems to have disappeared from the SysUtils unit
- Modified HelperFunctions.pas
- Added WriteStringToStream function
- Added SameValue and Supports functions for Delphi 5
- Added CreateObjectClass and ClonePersistentClass methods
- Modified GStreams.pas
- Added Close method to TGBufferStream (useful for .NET)
- TGSpecialFiler is not available for .NET (because can't crack
protected methods of TReader/TWriter)
- Modified GRegularExpression.pas
- Modified String references to AnsiString references (for .NET
compatibility). The Regular Expression object must use
AnsiString (one byte characters) because it uses set operations
which do not work with wide chars.
- Modified GParser.pas
- Changed StrScan calls to Pos, even though StrScan is faster it is not
.NET compatible
- Modified GLists.pas
- Added TQOrderedList class, which is base class for the TQxxx
stacks and queues, and TQOrderedListClass type. These classes
are useful because they have a virtual constructor, unlike
Borland's classes
- Modified GHashtable.pas
- Modified TGCustomHashTable to use a dynamic array of hash
table entries (THashtableEntries) instead of a pointer to
such an array (as used for Win32). The pointer implementation
was left for Win32 since it is faster than the dynamic array
implementation
- Modified GGraph.pas
- Changed TGCustomGraph.AddNode method visibility from protected
to public (.NET does not like changing visiblity with methods)
- Modified DataStructures.pas
- Added TFloatHeapElement, TFloatHeap, and TFloatPriorityQueue classes
- Changed TPriorityList.OrderedListClass to use GLists.TQOrderedList
instead of Borland's classes because we can't get to the items of the
list quickly
- Modified Structures.pas
- Added overloaded AddObject method to TGStringList
- Added RSGraphics.pas, moved from internal development package to common
classes library. Modified RSGraphics.pas as well:
- Added RSCenterPoint functions
- Added DrawPieSlice procedure
- Added DrawArrow procedure and TArrowOption types
- Changed Gradient functions to accept an open array of TColor,
instead of TColors
- Moved TObjectSize from Game.pas to RSGraphics.pas
- Created hierarchy of TRSCustomRect, TRSObjectRect, and TObjectSize
- Added TRSRect, TRSPoint and functions to manipulate them
- Added overloaded DrawShape procedures and TRSShapeStyle type
- Fixed LineGradient to handle "reversed" TRects (left > Right, etc)
- Fixed RotateFont to change font name if font is not a true type
(and wouldn't thus rotate)
- Added GetRotatedTextExtent function (Delphi's Canvas.TextExtent
does not work for rotated fonts)
-------------------------------------------------------------------
March 2005 Version 3.4
- Added RSConsts.pas and DataStructures.pas to package
-------------------------------------------------------------------
January 2005 Version 3.3
- Modified to work with Delphi 5, 6, 7, and 2005 (Win32)
- Added RSDefines.inc to simplify updates for new
versions of Delphi
- Modified source files to use RSDefines.inc
- Renamed GCollections package to RSCommon package for Delphi 2005 ONLY
- Modified source files to work with .NET (Incomplete)
-------------------------------------------------------------------
May 2004 Version 3.2
- Added RSGraphics and RSVector units to Common library
-------------------------------------------------------------------
March 2004 Version 3.1 (First Separated History for Common Library)
- Added code to TGCollection and TGCollectionItem to attempt to
mimic notifies like Delphi 6 and 7 collections
- Added IVector interface
- Changed ILocation interface to descend from ICloneable
- Installation script is much smarter about managing the different Delphi versions
