documentation
"
this class provides the interface to X11. It redefines all required methods
from DeviceWorkstation. Notice, that in Smalltalk/X you are not technically
limited to one display - in theory, you can create Views on many displays
simultanously. However, the default setup is for one display only.
To support multiple displays, you will have to start another event dispatcher
process for the other display(s) and create the other views with a slightly
different protocol. However, 'normal' applications do not have to care for
all of this ...
See more documentation in my superclass, DeviceWorkstation.
