That's not correct. The Qt license that comes with Kylix is only
allows you use in Kylix programs. Here is the relevant section
from the license information:
2.6 Restrictions on CLXDisplay API (Qt.pas) usage
---------------------------------------------------
CLXDisplay API, the Qt.pas interface to the Qt runtime, is
only licensed for use in VisualCLX applications or a
component that derives from TControl in the QControls
unit. A VisualCLX application is an application that
uses the TApplication object and uses at least one
component derived from TControl. You are not licensed
to use Qt.pas to create applications or components that
exclusively call the Qt.pas interfaces. The above restrictions
do not apply to applications or components licensed under the
GPL. A separate commercial development license from Trolltech
is required for use of Qt.pas in any manner other than
authorized above.
