Quite tricky modification, quite tough problem:
TGView frame (base of TGTextView) has a child window - TGViewFrame.
TGViewFrame is never actually painted (DoRedraw never gets called for this window),
but ... it receives Expose event and delegates it to ... its parent - TGTextView,
and TGTextView, it its DoRedraw (or DrawRegion) .... tries to paint into child window - TGViewFrame.
While this is may be OK for X11 or Window, with Cocoa it's a total mess and disaster - if some view is
to be updated, it does not expect a child to be suddenly rendered in the middle of work.
View is not a window.
I've added some quite risky code to address this problem (text scrolling is still wrong) - only
"static rendering" for a text view works now.

From Valeriy Onuchin:
TGView, TGTextView, TGTextEdit classes
The main changes :
o restructuring and revisiting the code
- move all text methods from TGView to TGTextView class.
o new methods
TGTextEdit::SetSelectBack - setting selection background color
TGTextEdit::SetSelectfore - setting color for slected text
TGText::AsString - return content as ROOT string.
o improved painting: exposed events, resizing
- compression of exposed events added which
eliminates flickering when text_edit widget is resized or
exposed.
- repaint only whose areas which where modified or
overlapped.
o undo management on Ctrl-Z
o autoscrolling when text is selected
o many small bug fixes:
- crash on double click on blank field
- selected text in some cases was not correctly removed
- etc.

Instead of providing default implementations for copy ctor's and assignment
operators we better make them private (and not implemented) to avoid people
from accidentally using them. Especially the collections classes and the
TQObject derived classes. In these classes the default implementations would
cause havoc due to multiple deletions of the same objects and other
potential memory corruptions.

From valeriy Onuchine:
- TImage, TASImage
o Change return type of Vectorize method from "void" to "Double_t*".
o Implement FromWindow method under X11. This method allows to
create "snapshot image" from any ROOT window or frame.
- config/Makefile.depend
Add dependency of libGuiBld lib on libGraf.
GuiBuilder uses internally TImage/TASImage class.
- GX11Gui.cxx
X11 error handler was slightly modified.
Many X11 errors lead to freezing X11 server and
did not allow debugging.
To prevent freezing, a "forced seg.violation" was added
to the error handler.
The usage of the new "feature" is the following:
0. run "gdb root.exe"
1. set "gDebug = (int)gVirtualX" - that activates the new error handling.
2. run application which has X11 errors.
On X11 error the application was stopped by the "forced seg.violation".
3. "gdb>bt" - backtrace the problem.
!!! A big list of changes in libGui initiated by gui builder development !!!
- TGButton.h, TGButton.cxx
TGButton class:
o SetDown methods removed from context menu.
o SetEnabled method of context menu changed to TOGGLE.

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 Onuchin:
- new class TImagePlugin is introduced;
To add possibility to read/write new image format one needs to create
a derived class and to override two methods:
virtual unsigned char *ReadFile(const char *filename, UInt_t &w,UInt_t &h)
virtual Bool_t WriteFile(const char *filename, unsigned char *argb,
UInt_t w, UInt_t h)
... and to specify it in the root resource file:
Plugin.TImagePlugin: ps TASPluginGS ASPluginGS "TASPluginGS(const char*)"
the name of plugin file extension DLL containing an implementation of
TImagePlugin subclass
- new class TASImagePlugin that is a subclass of TImagePlugin with ASImage
specific implementations;
- new class TASPluginGS - an image plugin class that allows to create images from
PS/EPS/PDF files and to display them in TCanvas/TPad. In addition, it allows to
browse PS/EPS/PDF files with the ROOT browser.
New files:
asimage/inc/LinkDefGS.h
asimage/inc/TASImagePlugin.h
asimage/inc/TASPluginGS.h
asimage/src/TASPluginGS.cxx
graf/inc/TImagePlugin.h
icons/pdf.xpm
icons/tb_find.xpm
libAfterImage.tar.gz
- TROOT.h
o new data member fClipboard and corresponding getter GetClipboard();
TSeqCollection *fClipboard; //List of clipboard objects;
- TGFrame
o embedded frames resized correctly now.
- TGCanvas
o several useful methods made public
- TGListBox, TGComboBox
o new method FindEntry(const char *s) added which returns entry by name
- TGMdiMainFrame, TGMdiDecorFrame
o fix bug which changed text color globally
o add displaying scroll bars when mdi frame is moved out of mdi
canvas viewport
- TGTextEdit/TGView, guitest
o added processing of:
2-clicks - selects a word
3-clicks - selects a line
4-clicks - selects the whole text
o change the key handling
Ctrl-F - invokes Search dialog
Ctrl-L - invokes Goto line dialog
Correspondent changes added to guitest.C and guitest.cxx (TextEdit test)
o readonly mode added
- TGSearchDialog
o Text entry was replaced by "text entry" combobox. It allows to
"remember" a history of entered search strings.

a global search dialog.
o Search method - display warning message box when object is not found
- TRootBrowser, mime.types
o possibility to browse PS/EPS/PDF fies added
o possibility to browse text files added. The content of text file
appears in "icon box" window (a la netscape)

From Valeriy:
- TGFrame dtor, TGFrame::Cleanup I omitted a call fList->Remove(el);
That caused a lot of problems. I appologize.
- TPad::Print(".gif") - added protection against warnings when loading
libAfterImage. Typo fixed.
- added protection against double deletion in TGComboBox, TGView dtors.
- TGListBoxt::InsertEntry - correct init of TGFrameElement

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" \

changed inheritance tree. Move TQObject inheritance from TGWidget to
TGFrame. This allows all frames to emit signals (all widgets were frames,
but not all frames were widgets). Added several missing signals in several
different widgets to get tutorials/guitest.C working.

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.

many improvements and fixes in the text edit widget. Fully implemented
cut/copy/paste between editor and any X11 window supporting text (and
vice versa). Also added a context menu giving access to the most essential
text editor actions (open, close, save, print, search, etc.). Fixed several
text navigation and selection issues.

infrastructure for the new TGTextEdit widget. The new TGView class is
the base class for all text viewing/editing widgets. TGTextView has been
totally rewritten to use the new TGView and TGText classes. TRootHelpDialog
uses the new TGTextView widget. TGTextEdit will derive from TGTextView.
