Remove
using namespace std;
from Riostream.h, which has huge consequences for all of ROOT.
Riostream.h is now a simple wrapper for fstream, iostream, iomanip for backward compatibility; Riosfwd.h simply wraps iosfwd.
Because of templates and their inline functions, Riostream.h needed to be included in headers, too (e.g. TParameter.h), which violated the assumption that Riostream.h is not exposing its using namespace std to headers.
ROOT now requires R__ANSISTREAM, R__SSTREAM, which does not change the set of supported compilers.
Without "using namespace std", several identifiers are now prefixed by std::; e.g. roofit/* source files now have a using namespace std to keep their coding style.
TFile::MakeProject() now generates "using namespace std" to convert the CINT-style class names into C++ ones.

- Allow to search substrings in TGCanvas subframe names.
This e.g. allows to search for partial branch names
when browsing a tree with the browser. To search
substring, just put a star anywhere in the search
pattern, e.g. *Track or Track* will find all branches
with name containing the string Track.
This has been requested on the forum:

From Valeriy Onuchin (tested by Bertrand):
o TGLayoutManager::IsModified method was overloaded.
This method is used to indicate that sub frames
changed/unchanged their positions/sizes after layout.
For example, in some cases positions&sizes of sub frames
can be unchanged after calling Layout method
(e.g. for TGTileLayout manager).
TGLayoutManager::IsModified will return kFALSE.
o TGListBox.h,cxx, TGCanvas.h,cxx, TGListTree.h,cxx,
TGListView.h,cxx
- new painting technique was implemented:
1. repaint only exposed/dirty regions.
Previously the whole view port (or even container frame)
was repainted.
2. use double-buffering (using back plane pixmap) during
repainting.
That allows to eliminate flickering during resizing,
scrolling, exposing/overlapping.
- several bugs were fixed:
o keyboard navigation in list view, list box, list tree
o resizing columns (details view) in list view
when horizontal scroll bar not in zero position.
o in list view (details view) buttons were moved when
it was resized.
o extra unnecessary repainting in list view, list tree
were removed.
o probably I missed something to mention .
o TGScrollBar
- bug fix: increment value was reset to 1 after button release.
- do not redraw scroll button if it's width/height was unchanged.
That reduces flickering

From Bertrand:
Added drag and drop support for Linux (Xdnd) and Windows (Clipboard).
It is now possible to drag an histogram (or any other graphical object)
from an opened file in TBrowser to any TCanvas.
It is also possible to drag a text file from TBrowser to a TGTextView
or TGTextEdit widget (i.e. in TGTextEditor).
On Linux, it is even possible to drag from a Root application to another
one, or to drag a text file (i.e. a macro) from the ROOT browser to an
external editor (i.e. Kate).
On Windows, drag and drop only works within the same ROOT application
(for the time being).

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 David Gonzalez Maline and Bertrand:
A bunch of modifications in TGFileDialog (mainly user requests):
- Sort files by name and not by type anymore.
- Increased the vertical scroll size.
- Implemented multiple file selection; can be turned on/off with a
checkbox on the TGFileDialog.
Here is an example of how to use multiple selection:
TGFileInfo fi;
new TGFileDialog(fClient->GetDefaultRoot(), this, kFDOpen,&fi);
if (fi.fMultipleSelection && fi.fFileNamesList) {
TObjString *el;
TIter next(fi.fFileNamesList);
while ((el = (TObjString *) next())) {
new TFile(el->GetString(), "update");
}
}
else if (fi.fFilename) {
new TFile(fi.fFilename, "update");
}

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.
Setting fWidgetFlags was added.
- TGTextButton class

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

From Valeriy Onuchin:
- new concept of "pseudo-window" introduced.
pseudo-window - is an object inherited from TGWindow which
is not created by window system (X11 or M$ Windows).
It does not consume window system resouces.
The main use-case of pseudo-windows is GUI containers
with very large number of items. For example, listviews, listboxes,
where listview/listbox items/entries are pseudo-windows.
Pseudo-window has "window id" equal to zero.
In order to "activate pseudo-window concept" the parent should
have fIsMapSubwindows dat member to be kFALSE.
So, it's backward compatible, setting fIsMapSubwindows=kTRUE in parent window
will activate normal behavior, i.e. will be created in window system.
Introduction of "pseudo-window concept" forced the changes in
TGX11, TGWin32 classes to avoid TVirtualX methods execution when
"window id" is NULL (the case of pseudo-window).
Introduction of pseudo-windows which do not consume window system resouces
greately improved performance of TGListView, TGListBox, TGComboBox objects.
Now it's possible to have these containers with more than 10000 items.
- some optimization in TGLBContainer drawing
- add SetWindowName to most GUI classes. It's very usefull for GUI debugging.

"reuse" key handling, e.g. arrow key navigation, "Page Up/Down", "Home/End" and
invocation of "Search Dialog" via "Ctrl-F" (usefull when one has 100000 entries in list box;-)

- protect TGListBox against double deletion during hierarchical cleaning.
- minor mod in TGListTree. ClassImpQ is obsolete.
- protect TGLVEntry against double deletion during hierarchical cleaning.
- protect TRootEmbededCanvas against double deletion during hierarchical
cleaning.
- protect TRootCanavs against double deletion during hierarchical cleaning.
- TGFontDialog. SetCleanup(kDeepCleanup) aka hierarchical cleaning is used
in destructor.
No segv. occured. That means all frames inside TGFontDialog are
"consistent with hierarchical cleaning".
Now TRootEmbededCanvas deleted without segv. during gui building.
- now TGuiBldQuickHandler is placed centered on parent when map_raised.
- TGuiBldDragManager. Double click on editable frame invokes resize/compact
action of the main-editable frame.

The goal:
1. required for guibuilder
2. providing ROOT I/O for GUI classes.
In all default constructors parent window is NULL,

From Ilka:
Any ROOT GUI can now be saved as a macro. Executing this macro brings back
the current GUI (minus the action handling). This very important development
allows to get easily the source for any GUI, which can then be inspected or
used to create other GUI's. Also this will allow a GUI builder to save and
restore GUI's.
To save the source of a GUI use the methods TGMainFrame::SaveSource() or
TGTransientFrame::SaveSource(), where the latter saves the source for dialogs.
To trigger the saving of any GUI just use ctrl-s.

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
