From Federico Carminati:
"I have implemented all copy and equal operators needed to silence all
warnings in AliRoot, as requested. I have implemented shallow copies as
would do the default operators synthetized by the compiler.
Most operators are protected. If users complain, you just have to move
them into the public area, but class derivation is of course supported.
It has been a terrible job, I have modified 278 files, but the changes
are backward compabile, and this goes a long way to permitting user to
use the effc++ flag with root headers."

From Valeriy:
TGPicture:
- fix deallocation autogenerated disabled pictures. That allows to fix
seg. violation after running $ROOTSYS/test/stress reported by Markus Frank.
An important comment was added to constructor
TGPicture(const char *name, Pixmap_t pxmap, Pixmap_t mask)
"both pixmaps pxmap and mask must be unique (not shared)"
- new method TGPicturePool::GetPicture(const char *name, char **xpm) added
that allows to create pictures from in-memory XPM array
Example:
#include "myicon.xpm" // contains static char** myicon {..} array
const TGPicture *pic = gClient->GetPicturePool()->GetPicture("myicon",
myicon);
TGButton:
- new method SetEnablled added which allows to activate/deactivate
enabled/disabled state of button
TASImage/TImage:
- Few new vector graphics methods added:
DrawCubeBezier, DrawStraightEllips, DrawCircle, DrawEllips,DrawEllips2
ToGray method, which allows to convert RGB image to Gray image
TImageDump:
- open circle polymarkers are implemented

From Valeriy Onuchin:
- TASImage, TRootBrowser, TGMimeTypes.cxx
The size of image thumbnail was enlarged from 32x32 to 64x64 pixels.
Appearance of picture thumbnails was much improved.
- TGPicture. Fix possible buffer overflow in HashName method.
- TRootCanvas. Possibility to save canvas in XCF format added.
This format is used in the GIMP (image processing program).
In general the new method of dynamical creation of object's icon can be
extended for any kind of objects.

From Valeriy Onuchin:
- massive update of TImage/TASImage class.
- update rose_image.C macro to demonstrate new features.
- new example hist2image.C added
I'll try to add more example and documentation asap.
- bug fixes in ROOT gui builder
- TGToolBar, TGShutter now "compatible" with hierarchical cleaning
- mods in TGPicture allow create masked pictures from images.

From Valeriy Onuchin:
- new method GetPicture added to TImage,TASImage classes
That allows to create TGPicture not only from XPM files but
also from png, jpg, gif, tiff files.
An example, of usage:
TImage *img = TImage::Open("rose512.jpg");
const TGPicture *pic = img->GetPicture();
TGPictureButton *btn = new TGPictureButton(parent, pic)
- TGPicturePool::GetPicture(const char *name, Pixmap_t pxmap) added
That allows to create TGPicture from given pixmap. For example, that will allow,
to create TGPicture from TPad.
- TGPicturePool::GetPicture(const char *name) return picture for supported
image formats xpm, png, jpg, gif, tiff
Now it's possible to create TGPictureButton, TGImageMap from files of these formats.
- default ROOT browser actions changed for png, jpg, gif, tiff files. That allows
to browse these file with TBrowser

major changes in the resource management of the GUI classes. Introduced the
new class TGResourcePool which loads and keeps track of the 3 main resource
pools: fonts, picture and graphics contexts. Fonts are now handled via the
new TGFont class (and TGFontPool). In the past the loading of these resources
was done in TGClient and required all GUI classes to have TGClient as friend
to have their global statics initialized by TGClient. Adding a new widget
required TGClient.cxx to be changed too. This was obviously not good.
In addition it is now possible to find the full definition of the original
resource back based on a resource handle (GContext_t or FontStruct_t yielding
a TGGC or TGFont) which is needed for the SavePrimitive() functionality.
The resource pool can be found via TGClient (e.g. gClient->GetResourcePool()).
To see all active graphics contexts, fonts and pictures do:
gClient->GetResourcePool()->GetGCPool()->Print()
gClient->GetResourcePool()->GetFontPool()->Print()
gClient->GetResourcePool()->GetPicturePool()->Print()
For more examples see the widget source code.
These changes are largely backward compatible except maybe for some low
level 3rd party widgets that use some TGFrame internals. In these cases
the following sed command will patch the code:
sed -e "s/fgBlackGC()/GetBlackGC()()/g" \
-e "s/fgWhiteGC()/GetWhiteGC()()/g" \
-e "s/fgHilightGC()/GetHilightGC()()/g" \
-e "s/fgShadowGC()/GetShadowGC()()/g" \
-e "s/fgBckgndGC()/GetBckgndGC()()/g" \
widget.cxx > widget.cxx.new

W A R N I N G !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
==================================================================
A very long list of changes in this pre-release of version 3.00.
We have modified the signature of many functions (in particular TObject)
to introduce more constness in the system.
You must change your code if your class derives from TObject and uses
one of the modified functions such as ls, Print, Compare, Hash, etc.
The modified functions in TObject have the following signature:
virtual TObject *Clone() const;
virtual Int_t Compare(const TObject *obj) const;
virtual void Delete(Option_t *option=""); // *MENU*
virtual void DrawClass() const; // *MENU*
virtual void DrawClone(Option_t *option="") const; // *MENU*
virtual void Dump() const; // *MENU*
virtual TObject *FindObject(const TObject *obj) const;
virtual char *GetObjectInfo(Int_t px, Int_t py) const;
virtual ULong_t Hash() const;
virtual void Inspect() const; // *MENU*
virtual Bool_t IsEqual(const TObject *obj) const;
virtual void ls(Option_t *option="") const;
virtual void Print(Option_t *option="") const;
A similar operation has been done with classes such as TH1, TVirtualPad,
TTree, etc.

many change connected with the introduction of the TGGC (graphics context)
class (all backward compatible). Also many of the static default GC's and
fontstructs are now available to the user. This can simplify code in many
places. See change in guitest.cxx.
