From Valeri Fine:
TGQt class:
- Introduce the new TQtTextProxy abstract interface to allow the end
user
to provide his/her own custom text handler if needed.
The "default" behavior - no TQtTextProxy is used.
- Two new methods to query the current Qt font properties:
Int_t TGQt::GetFontAscent() const
Int_t TGQt::GetFontDescent() const
TQrMarker class:
- ROOT marker rendering implementation has been moved
from TGQt to TQtMaker class
TQtSymbolCodec:
- clean up comments; remove Qt3 CPP flags.
TQtPen:
- re-implement TAttLine interface.
Add default copy ctor and "operator="
TQtBrush:
- add TAttFill interface.
TQtSymbolCodec
- add TAttFill interface
TQtWidget
- add the refresh timer to get rid of the redundant rendering.

TGQt.cxx, TQtWidget.cxx, TQtWidget.h:
- Take in account the Qt 4.5 feature that allows for
the mouse "synthetic" Leave / Enter / Move events
without crossing the widget borders.
(Thanks Bradley T. Hughes, Senior Software Engineer from Nokia)
TQtWidget.h:
- Remove some redundant methods. (keeping cleaning after Qt3
TGQt.cxx:

From Valeri Fine:
TQtRootSlot:
- Add the new method
void ProcessLine(const QString &command)
This is an overloaded member function, provided for convenience.
It is provides the same functionality as
void ProcessLine(const char *command)
TGQt:
- Swap "y2" with "y1" provided by TBox::ExecuteEvent method
for the right low corner of the rubber box.
- Clean up. Remove some redundant code,
TQtClientWidget
- Add setAutoFillBackground(true) Qt4 property.
TQtWidget:
- Intdroduce the optional QImage-based back-end (slower operation).
QPixmap-based is the default option ( better performance )
rootlibs.pri:
- Change the list of the dictionaries for Win32 platform.

From valeri Fine:
This patches TGQt and TQtWidget classes:
- The paint engine was redesigned to meet Qt 4.4.1 constrain on Windows platforms
- Optimize the TCanvas rendering for Qt4
- Add the Qt4 include directories to the ACLiC list of the include directories, if needed
- Implement TCanvas "feed back" option with Qt4 by adding 3 local classes:
TQtPainter - to subclass the Qt4 QPainter
TQtFeedBackWidget - to render the "non-buffered" TCanvas painting
TQtToggleFeedBack - to toogle feedback mode

From Valeri Fine:
This is the major patch because as soon as it is applied one can not
build the QtRoot package against Qt3 anymore. This allows to resolve
some Qt4 outstanding issues:
- TGQt class:
move the font and the line attributes handling to the separated
dedicated C++ classes, namely TQtPen and TQtFont.
Fix the race condition that leaded under certain circumstances
to 100% CPU consumption under Qt4
- new class TQtPen - to handle the line drawing ROOT attributes.
- TQtFont - correctly adjust the Qt fonts scale to
the ROOT requirements
- Improve performance of the TCanvas double buffering option
- TQtBrush - implement the ROOT transparent brush style
- TQtClientWidget - fix some background color issues
(some work still needed)
- TQtWidget - use the Qt4 "redirect" painting option to handle the
ROOT double buffering. Eliminate the confusing X11 run-time error
messages at ROOT startup.

From Valeri Fine:
TGQt:
* Comments clean up
* 2 news protected static methods:
static Int_t RegisterWid(QPaintDevice *wid);
static void UnRegisterWid(QPaintDevice *wid);
to resolved the potential 64-bits platform problems
* Some extra fixes to facilitate the 64-bits platforms
* TQtWidget
- new Qt signal:
RootEventProcessed(TObject *selected, unsigned int event,TCanvas
*canvas)
where
"selected" - is a TObject has been selected
by the current TPad
"event" - ROOT event processed by TCanvas.
This Qt signal allows forward the "ROOT signal" to Qt "slot".
By default, TQtWidget emits no "RootEventProcessed" for sake
of the performance.
Any user-code can activate the signal emitting with a bunch
of the new methods. See next point
* A bunch of the methods to facilitate the new Qt Signal:
void EnableSignalEvents (UInt_t f);
void DisableSignalEvents (UInt_t f);
Bool_t IsSignalEventEnabled(UInt_t f) const;
where "f" is logical combination of the bits to activate
the emitting the RootEventProcessed Qt signal as soon as
TCanvas ROOT event forwarded by Qt-layer
kMousePressEvent = BIT(0), // mousePressEvent QMouseEvent
kMouseMoveEvent = BIT(1), // mouseMoveEvent QMouseEvent
kMouseReleaseEvent = BIT(2), // mouseReleaseEvent QMouseEvent
kMouseDoubleClickEvent = BIT(3), // mouseDoubleClickEvent QMouseEvent
kKeyPressEvent = BIT(4), // keyPressEvent QKeyEvent
kEnterEvent = BIT(5), // enterEvent QEvent
kLeaveEvent = BIT(6) // leaveEvent QEvent
* TQtApplication
A special DISPLAY env varaible value QT_BATCH
to use Qt layer with "non-gui" mode
(in case when no X11 connection is provided)

So that the following now works:

Add a new package "qt". Developed by Valeri Fine (fine@bnl.gov), this new
package is an implementation of TVirtualX based on the Qt library from Trolltech AS, Norway.
The package is optional. When configuring ROOT, you can generate the libQtRoot
library by adding, eg
--enable-qt \
--with-qt-incdir=$QT/include \
--with-qt-libdir=$QT/lib \
where $QT points to the directory where the Qt software has been installed.
The Qt version >= 3.1 is required for this interface.
The Qt package itself must have been compiled with the same compiler
and compiler options used to compile ROOT.
Once the $ROOTSYS/lib/libQtRoot.so (dll) library is created, one has
the possibility to select this library as an alternative to libGX11
by adding the following two lines in the local ".rootrc" file
Gui.Backend: qt
Gui.Factory: qt
The package has currently been tested on Linux only.
This first implementation may show some deficiencies compared to
the libGX11 default version.
Please report any problems with this version to
rootdev@root.cern.ch as well as fine@bnl.gov
