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.

1. TGCanvas - draws anything only if exposed region is not empty and MAKES it empty,
thus constant (by nature) function modifies object's state. This makes it impossible
to paint the same widget twice by calling DoRedraw, the second time exposed region is empty.
This does not work with cocoa.
2. CreateFontCollection for a specific name always finds only 1 font, not all variations of the same font,
instead I have to request the full list every time and filter it myself.
3. TGFontDialog: connects signal/slot only for gVirtualX inherited from TGX11 (or TGX11 itself),
must also work for TGCocoa. all_sizes and all_styles variables also were set incorrectly for TGCocoa
(initialization uses check InheritsFrom("TGX11")).

- 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 Andrew Savchenko:
ROOT can not be compiled with gcc-4.3.
Some ROOT source files doesn't contain required #include directives,
for example, they use strlen(), but #include <string.h> is missed or
malloc() is used and #include <stdlib.h> is missed.
Earlier versions of gcc allowed some headers to be included implicitly,
but issued a warning (-Wimplicit-function-declaration). Newer one,
gcc-4.3 denies such silly behaviour: all required headers must be explicitly
included.
Attached patch fixes this. Also it fixes another issue, which disallows
ROOT to compile under gcc-4.3: C functions don't belong to namespace std,
so expressions like std::memcpy() are no longer valid and plain memcpy()
should be used instead.

From Valeriy O. and Bertrand:
this patches intend to fix creation of pixmap
with very large sizes. It happens when list tree or
list view resized to width = 0. In this case in
TGViewPort::HandleConfigureNotify(Event_t *event)
event->fWidth has very large value. i.e. > 65000
Protections added against such cases.

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

should be called by user.
o new methods:
void SetFont(TGFont *font);
void SetColor(Pixel_t color);
void SetAlign(Int_t align);

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 Bertrand and Valeriy Onuchin:
- TGGroupFrame::ChangeOptions method was introduced
which overloads TGFrame::ChangeOptions. Using
TGFrame::ChangeOptions corrupted fBorderWidth data member.
- TGFrame::SetEditable. Disable edit frame when kEditDisableLayout
bit in fEditDisabled flag is activated.
- TGCompositeFrame::SetEditDisabled.
Propagate fEditDisable flag to subframes only for cases
of kEditDisable and kEditEnable values.
- TGCanvas constructor. Set correct value of fEditDisable flag.
That allows to use TBrowser during guibuilding. The idea is to
use TBrowser as an object inspector of edited widgets.
Note by Ilka: this protection is not enough because the search dialog of
the browser, or status bar became editable when GUI builder is active.
We agreed that more protections is needed at that point.
- TGStatusBar constructors. Set correct values for fEditDisabled flag
which allows to use status bars in guibuilding.

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.
o new static method TGSearchDialog *&gDialog() introduced. It returns
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)
o "Search" tool bar button added. It activates the "search dialog" for
searching a specified icon or text when a text file is browsed.

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.

From Valeriy Onuchin:
- TRootEmbeddedCanvas added to GuiBuilder widgets palette
- slightly modified TRootEmbeddedCanvas::SavePrimitive to avoid name clash
- TGFrame::HandleEvent minor mod to activate guibuilding
- correct TGCanvas::MapSubwindows. Previous implementaion always mapped
scrollbars even if they must be unmapped

The following mega patch is from Ilka. She has integrated and further
developed the original classes from Marek Biskup (summer student last year)..
Valeriy Onuchin has also contributed by extending/adapting existing
GUI classes.
Very first prototype of the new pad editor is available for testing and
feedbacks. It was started by Marek Biskup as his project during the
Summer Student Program 2003.
The new pad editor helps ROOT GUI to become closer to the well known
application GUIs; to be user friendly, having easier and faster access
to the ROOT graphics, to be more intuitive. It is embedded in the
TCanvas window every canvas has an editor.
The editor frame is on the left side of the canvas window. The user can
show it via Edit/Editor menu selection. The editor frame contains a set
of picture buttons for selecting well known graphical primitives for
drawing; below them there are widgets for attribute changing. When an
object is selected its name appears with a set of options available for
changing: fill style and color; line style, width and color; text font,
size and style; marker style, size and color.
New Classes:
TGFontTypeComboBox - a combo box with fonts for a choice;
TGLineWidthComboBox - a combo box with line widths;
TGLineWidthLBEntry - list box entry for different line widths
TGLineStyleComboBox - a combo box with line styles;
TGLineStyleLBEntry - list box entry for a line style
TGedEditor - the new editor containing tool-box and attribute frames of
the selected object;
TGedToolBox - frame with picture buttons for a primitive drawing
TGedAttFrame - a base class for all attribute frames
TGedAttNameFrame - a frame showing the selected object name (if exists)
TGedAttFillFrame - a frame showing the fill attributes
TGedAttLineFrame - a frame showing the line attributes
TGedAttTextFrame - a frame showing the text attributes
TGedAttMarkerFrame - a frame showing the marker attributes
TGedPatternFrame - popup window for fill pattern selection
TGedPatternSelector - a button for pattern selection
TGedSelect - service class for selecting
TGedPopup - service class for popup attribute window
TGPatternSelect - a button for selected pattern
TGedMarkerPopup - popup window for marker selection
TGedMarkerSelect - a button for selected marker
Several changes are made in TCanvas, TPad, TRootCanvas to adapt them for
the new GUI interface. The old GUI interface is kept and it can be used
too. The class TPadEditorOld provides its functionality.

From Valeriy Onouchin
- flicker-free scrolling is implemented for TGContainer class.
Scrolling through listview looks much better now. One of the nice
"side effects" of solving "limited list box entries" bug.
- followups mods after solving "missing horizontal scroll bar in detailed view" bug
TGListDetailsLayout constructor modified for SavePrimitives method.

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.

From Valeriy Onuchin:
- KeyPressed signal and correspondent SendMessage added
to TGListTree and TGContainer classes
That will allow to add user defined key-handling
procedures to ROOT browser (request from Olivier Stezowski)
- follow-ups after TGStatusBar yesterday changes:
TGStatusBar is derived now from TGHorizontalFrame

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 improvements by Valeriy Onuchin. In particular the TGListTree
should now be able to handle very large tree's (not limited anymore by
the bitmap size). Added key navigation options to TGListTree and some
new signals.

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.
