Content description : classes , structures, etc ...

Several classes are pure virtual classes, and will be linked with architecture part (libvclplug_aqua on native port )

Classes defined

- ImplLayoutRuns
 ImplLayoutRuns methods: various methods around actions in progress
 Clear( ), AddPos( ), AddRun( ), IsEmpty( ), ResetPos( ), NextRun( ), GetRun( ), GetNextPos( ), PosIsInRun( )

- ImplLayoutArgs
 ImplLayoutArgs : various methods around parameters to provide "Run" methods [FIXME] : not completely sure, needs verification
 SetLayoutWidth( ), SetDXArray( ), SetOrientation( ), ResetPos( ), GetNextPos( ), GetNextRun(), NeedFallback( ) 
 ( three definitions, with two overloaded), PrepareFallback( )  [FIXME] : define fallback properly

- SalLayout      <=  all text implementations inherit from this class, from far essential
 SalLayout methods: InitFonts( ), LayoutText( ), AdjustLayout( ),FillDXArray( ) DrawBase() , DrawOffset( ), DrawText( ),GetTextBreak( ),
 GetNextGlyph( ), GetOutLine( ), GetBoundREct( ), IsSpacingGlyph( ), GetCaretPosition( ), GetDrawPosition( ), GetUnitPerPixels( ),
 GetOrientation( ), GetDrawPosition( )

- MultiSalLyout [FIXME] not completely clear
- Generic SalLayout

Corresponding implementation :  sallayout.cxx

Includes from STLport : list, vector

Other includes : tools.h , dllapi.h

Sources using this header in vcl

One main file for font services in OpenOffice.org, this header is mainly used in vcl :

./salatslayout.cxx:#include <sallayout.hxx>

./source/gdi/outdev.cxx:#include <sallayout.hxx>

./source/gdi/outdev2.cxx:#include <sallayout.hxx>

./source/gdi/outdev3.cxx:#include <sallayout.hxx>

./unx/source/window/salframe.cxx:#include <sallayout.hxx>

./win/inc/salgdi.h:#include <sallayout.hxx>

Windows specific :

./win/source/gdi/salgdi3.cxx:#include <sallayout.hxx>

./win/source/gdi/winlayout.cxx:#include <sallayout.hxx>

./win/source/window/salframe.cxx:#include <sallayout.hxx>

./source/window/window.cxx:#include <sallayout.hxx>

Several approaches are necessary :

To be implemented

-> same implementation in vcl/aqua directories
