1. UI & Interfaces : latest updates

2. Outlook
Qt UI commands G4UIExective MPI interface Python Interface

3. Qt Stable on Linux / Qt4 Prescription for Mac configuration
Qt3 support will be dropped.
SL4 (RH ES4) is affected.

4. Range check for UI commands
improve range check for UI commands with default unit
G4UIcmdWithADoubleAndUnit
G4UIcmdWith3VectorAndUnit
Default unit should be set
For example,
/xxxx/setLength 1 m
0 < x < 10 (cm)
Range Error !

5. /control/ commands New stuff Usage:
/control/if <alias> “< <= > >= == !=“ <macro>
/control/add <alias> <value1> <value2>
/control/subtract <alias> <value1> <value2>
/control/multiply <alias> <value1> <value2>
/control/divide <alias> <value1> <value2>
Usage:
control/if {alias_name} > 1 macro.mac
If “alias_name” > 1, then execute “macro.mac”

6. G4UIExecutive G4UIExecutive is available in 9.3 release.
convenient class for selecting a UI session according to environment variables, G4UI_USE_XXX.
QT, XM, WIN32, TCSH, UIterminal (fallback)
select a session type by the order above
Pros: just one line cares the selection of a session type
Cons: Environment variables might cause unexpected behaviors.
G4UIExective is used in all examples.
an aspect of code review for examples

7. G4UIExecutive in main()
In your main(),
#include “G4UIExecutve.hh” …
if (argc != 1) { // batch mode
G4String fileName = argv[1];
UImanager-> ApplyCommand(“/control/execute ” + fileName);
} else { // interactive mode
G4UIExecutive* ui = new G4UIExecutive(argc, argv);
if (ui-> IsGUI()) ; // say something
ui-> SessionStart();
delete ui; }

8. MPI interface Code reviewed OpenMPI as default instead of LAM/MPI
LAM/MPI is becoming obsolete …
Developers shift to OpenMPI
does not work on recent distributions
improve macro file parser
same parser as G4UIbatch
Improve /mpi/status command
clock counting with checking kernel status
changed "beamOn" behavior for better performance
fixed unexpected behavior at the end of batch mode

9. Python interface Now Ready for Python 3
Boost-Python is ready for Python3
Some distributions include Python3
Python 3 is not backward compatible
Python2 script cannot run on Python3
Codes for both Python2 and Python3 should be provided.
Experimental support for Python3 on December release.

10. New example of GTK application
EM Calculator
pyGTK is used.
Show stopping power for e/mu/proton and cross section for gamma
Select a particle and select/set a NIST material
Show stopping power / cross sections on ROOT graph and text data

11. Summary Qt interface UI comands G4UIExective MPI interface
stable on Linux
prescription for Mac configuration
drop Qt3 support
UI comands
improve range check
new control stuff
G4UIExective
uniform way of UI session
MPI interface
code reviewed for better performance
Python interface
ready for Python3
example of GTK application
