2a0795c6fSMarcus Overhagen //
3a0795c6fSMarcus Overhagen // * PURPOSE
4a0795c6fSMarcus Overhagen //	 Window subclass to contain BMediaTheme generated 'parameter
5a0795c6fSMarcus Overhagen //	 views' and offers elegant resizing/zooming behaviour.
6a0795c6fSMarcus Overhagen //
7a0795c6fSMarcus Overhagen //	 The ParameterWindow currently listens to the MediaRoster for
8a0795c6fSMarcus Overhagen // 	 changes of the parameter web, but this should change when the
9a0795c6fSMarcus Overhagen //   provided BMediaTheme becomes more 'intelligent'.
10a0795c6fSMarcus Overhagen //
11a0795c6fSMarcus Overhagen //	 Support for selecting alternate themes is planned, but not
12a0795c6fSMarcus Overhagen //	 yet finished (see the 'Themes' menu)
13a0795c6fSMarcus Overhagen //
