heh.. this gets tricky. You can try this:

; wid is the widget id of the cw_slider widget
wid = cw_slider( .. )

; x = new slider max, y = new slider min
widget_control, widget_info( wid, /child ), get_uvalue = state, /no_copy
widget_control, state.slideid, set_slider_max = x, set_slider_max = y
state.top = x ;update the cw_slider state structure
state.bot = y
widget_control, widget_info( wid, /child ), set_uvalue = state, /no_copy

I havent tried this, but I'd say its definitely worth a shot...
