This is an experimental UI interface, not yet ready for general use.
|
|
|
55 |
|
|
|
56 |
This class provides the interface to the GUIServer.
|
|
|
57 |
It redefines all required methods from DeviceWorkstation.
|
|
|
58 |
|
|
|
59 |
The GUIServer is a little Java program, which provides a socket interface,
|
|
|
60 |
allowing for GUI operations to be sent and events to be received.
|
|
|
61 |
Thus providing a platform independent, portable and nice looking GUI interface alternative.
