| 43 | <p> <b>Roles of the "intercoms" category</b> </p> |
|---|
| 44 | <div class="MsoNormal"> The "intercoms" category provides an expandable |
|---|
| 45 | command interpreter. It is the key mechanism of Geant4 to realize user interactions |
|---|
| 46 | of all categories without being annoyed by the dependencies among categories. |
|---|
| 47 | The direct use of Geant4 classes in a C++ program offers a first ground level |
|---|
| 48 | of interactivity, i.e., the batch session. As seen in the examples/novice/N01, |
|---|
| 49 | Geant4 commands and macros are to be hard-coded in the program.</div> |
|---|
| 50 | |
|---|
| 51 | <p> <b>User Interfaces to steer the simulation</b> </p> |
|---|
| 52 | <div class="MsoNormal"> To avoid too much programming, the "intercoms" |
|---|
| 53 | category provides the abstract class <i>G4UIsession </i>that captures interactive |
|---|
| 54 | commands . The concrete implementation of the user interface and Graphical |
|---|
| 55 | User Interfaces (GUI) is left to the interfaces category. This interfacing |
|---|
| 56 | strategy opens an important door towards various user interface tools and |
|---|
| 57 | allows Geant4 to utilize the state-of-the-art GUI tools such as Motif and |
|---|
| 58 | Java, etc..The richness of the collaboration has permitted for different groups |
|---|
| 59 | to offer various user interfaces to the Geant4 command system. Currently available |
|---|
| 60 | are the following; |
|---|
| 61 | <ol> |
|---|
| 62 | |
|---|
| 63 | <li> Character terminal (dumb terminal and tcsh(bash)-like terminal), the |
|---|
| 64 | default user interface of Geant4,</li> |
|---|
| 65 | |
|---|
| 66 | <li> Xm, Xaw, Qt, Win32, variations of the upper terminal by using a Motif, |
|---|
| 67 | Athena, Qt or Windows widget to retrieve commands, and</li> |
|---|
| 68 | |

|---|
| 212 | graphical user interfaces, GAG (Geant4 Adaptive GUI) and Gain (Geant4 adaptive<br> |
|---|
| 213 | interface for network). While GAG must run on the same system (Windows or |
|---|
| 214 | Unixen) as a Geant4 application, Gain can run on a remote system (Windows, |
|---|
| 215 | Linux, etc.) to which JVM (Java Virtual Machine) is installed. A Geant4 application |
|---|
| 216 | is invoked on a Unix (Linux) system and behaves as a network server. It opens |
|---|
| 217 | a port, waiting the connection from the Gain. Gain is capable to connect |
|---|
| 218 | to multiple Geant4 "servers" on Unixen systems at different institutes.<br> |
|---|

|---|
| 223 | <br> |
|---|
| 224 | GAG is a Graphical User Interface tool with which user can set |
|---|
| 225 | parameters and execute commands. It is adaptive, since GAG reflects the internal |
|---|
| 226 | states of Geant4 that is a state machine. GAG is based on the server-client |
|---|
| 227 | model; GAG is the server, while Geant4 executables are clients. Hence, GAG |
|---|
| 228 | does nothing by itself and it must invoke an executable simulation program. |
|---|
| 229 | Geant4's front-end class <i>G4UIGAG </i>must be instantiated to communicate |
|---|
| 230 | with GAG. This runs on Linux and Windows 2000.</div> |
