Understanding themes


Hmm, I'm confused about the themes.
I' already made themes from theme roller for 1.6 to work with jui
1.6r5 and jquery 1.3.
But now I have a doubt: which files do I need to include? Currently
I'm including core, theme and the widget specific css file, but the
problem is that the last CSS loaded seems to apply the theme to all
the widgets, whatever they are.
Is it possible to have, lets say, a datepicker with the dotluv theme
and a slider with the redmond theme?, or the theme will be globally
applied to all jui widgets on the page?
