Typically an application's "main window" will be a TDEMainWindow or
a subclass of TDEMainWindow (TDEMainWindow provides simple mechanisms
for constructing mens, toolbars, statusbars, etc). The problem with
using TDEMainWindow in a System Tray application is that when
TDEMainWindow is closed, it also shuts down TDEApplication and the
program terminates.

One way around that (not necessarily the best way - see systray1.py)
is to make the "main window" a TQWidget or other TQWidget subclass
that's not TDEMainWindow.
