Class TFileNameIterator

new operators:

Please note:

const WIN32_FIND_DATA& operator ++();
const ffblk& operator ++();
const ffblk& Current() const;

All this stuff has been replaced with TFileStatus& as return value.

Its recommended don't use explicit return value of this operators, :use TFileStatus, it is more portable.

Additions in to gadget system.

Gadgets system now support flat style ala I.E. .
To enable this functionality call static functions TGadgetWindow::EnableFlatStyle(true); and static function: bool TGadgetWindow::GetFlatStyle()
New TFlatHandleGadget to support handle for docked toolbar.
New predefined gadget Id: IDG_FLATHANDLE

Additions in Docking system

New message EV_WM_OWLWINDOWDOCKED

Additions into TWindow

TWindow now has Tooltip member, this allow simple additions tooltip in every window(include dialog box)
New members of TWindow:

LPCSTR GetClassName();                         - Now it return const _TCHAR*
bool LockWindowUpdate(bool lock=true) - lock/unlock windows update
bool IsWindowVisible()                              - now if window not created use WS_VISIBLE flag

Not documented TFixedPoint

I don't found documentation on TFixedPoint class also OWL uses it.
TFixedPoint defined in "fixedpnt.h"

Usage:
    TFixedPoint a,b,c;
    a = 5;
    b = 10;
    c = 25;
    a = (a *b)/c *25;
    b = a -34
    int  result = b;

Revised TRecentFiles class

Added Registry support and enhanced visual representation recent file in menu.

Changed constructor:

TRecentFiles(LPCTSTR iniOrKeyName, int numSavedFiles = MaxMenuItems, int namelen = 30, bool useRegistry=false);

Where:
    iniOrKeyName  - ini file name or Registry filename:
        example:
            ini file name:     "some file"
            registry name:  "Software\\OWL NExt\\MRUTest"
    numSavedFiles    - number files shown in menu and saved to registry.
    namelen                - maximal file length as it will be shown if menu
    useRegistry         - Use registry if true, for compatibility reasons default false

Additions in TDecoratedFrame and TFrameWindow

Additions in TFrameWindow => support for Control Bar switching:
This are base do nothing functions
void                      SetBarDescr(TBarDescr* barDescr, TAutoDelete = AutoDelete);
const TBarDescr*   GetBarDescr() const;
virtual bool           MergeBar(const TBarDescr& childBarDescr);
virtual bool           RestoreBar();
Additions in TDecoratedFrame => support for Control Bar switching:
virtual bool MergeBar(const TBarDescr& childBarDescr);
virtual bool RestoreBar();
virtual bool CreateBar();
Actual implementation of ControlBar switching

Additional Functions:
        void SetBarCreator(const TGadgetWndFunctor& funct);
        void SetBarInserter(const TBarInsertFunctor& funct);
        TGadgetWndFunctor* GetBarCreator();
        TBarInsertFunctor* GetBarInserter();
TGadgetWndFunctor -> function callback property called in CreateBar()  to create ControlBar, default implementation:
static TGadgetWindow* CreateToolBar(TWindow* wnd)
{
    return new TControlBar(wnd);
}
To replace it you have to define function like this
TGadgetWindow* CreateToolBar(TWindow* wnd)
{
return new TDockableControlBar(wnd);
}
or
TGadgetWindow* TMyWindow::CreateToolBar(TWindow* wnd)
{
   returnnew TDockableControlBar(wnd);
}
And use for function
    frame->SetBarCreator(TGadgetWnd_FUNCTOR(CreateToolBar));
or for member function
    frame->SetBarCreator(TGadgetWnd_MFUNCTOR(this,&TMyWindow::CreateToolBar))

TBarInsertFunctor -> called in CreateBar() to Insert ControlBar, default implementation:
bool EvBarInserter(TDecoratedFrame& frame, TGadgetWindow& destWindow, TAbsLocation loc)
{
    // Setup the toolbar ID
    destWindow.Attr.Id = IDW_TOOLBAR;
    if(frame.GetHandle())
        destWindow.Create();
    frame.Insert(destWindow, TDecoratedFrame::TLocation(loc));
    return true;
}
To replace it, you have to define function like this
bool EvBarInserter(TDecoratedFrame& frame, TGadgetWindow& destWindow, TAbsLocation loc)
{
return ..;
}
or
bool TMyApplication::EvBarInserter(TDecoratedFrame& frame, TGadgetWindow& destWindow, TAbsLocation loc)
{
    Harbor = new THarbor(frame);
    TDockable* dockable = TYPESAFE_DOWNCAST(&destWindow, TDockable); // not checked, maybe REINTERPRET_CAST
    if(!dockable)
return false;
    Harbor->Insert(*dockable, loc);
   return true;
}
And use for function
    frame->SetBarInserter(TBarInsert_FUNCTOR(EvBarInserter));
or for member function
    frame->SetBarInserter(TBarInsert_MFUNCTOR(this,&TMyApplication::EvBarInserter));

Additions in TApplication

typedef int (*TMessageBox)(HWND wnd, LPCTSTR text, LPCTSTR caption, uint type);

Global funcitons:
_OWLFUNC(TMessageBox) SetDefMessageBox(TMessageBox);
_OWLFUNC(int) OWLMessageBox(HWND wnd, LPCTSTR text, LPCTSTR caption, uint type);
_OWLFUNC(int) OWLMessageBox(TWindow* wnd, TResId resId, LPCTSTR caption, uint type, TModule* module = 0);

New functions to change default MessageBox

New member function of TApplication:

int MessageBox(HWND wnd, uint resId, LPCTSTR caption=0, uint type = MB_OK, ...);

Enhanced TAnimateCtrl

bool Open(LPCTSTR fileOrRes, TModule* module=0); - Added TModule where look for resource, Only for new Commctrl.dll

TCheckListItem and TCheckList

Numerous enhancement, see source and example

TDecoratedFrame

// Virtuals from TFrameWindow
virtual bool MergeBar(const TBarDescr& childBarDescr);
virtual bool RestoreBar();

virtual TGadgetWindow* GetControlBar();

TObjProperty<TGadgetWndFunctor>    BarCreator;       
TObjProperty<TBarInsertFunctor>         EvBarInsert;

TDialog

Added handler for WM_WINDOWPOSCHANGED.

TView

New functions:
    virtual TBarDescr* GetViewBar();

     int     PageDown(); // EM_SCROLL, SB_PAGEDOWN     Scrolls down one page.
     int     PageUp(); // EM_SCROLL, SB_PAGEUP     Scrolls up one page.
    EvUpDown() -  UpDown handler
   throw out GetHahdle()/SetHandle(), it now only GetMemHandle()/SetMemHandle() valid

TRichEdit
