Ok, if all you want to do is change the range of values returned by
a cw_fslider() widget, this will definitely work

wid = cw_fslider( ... )

widget_control, widget_info( wid, /child ), get_uvalue = state, /no_copy
state.top = new_max
state.bot = new_min
widget_control, widget_info( wid, /child ), set_uvalue = state, /no_copy

This will not change the label if the value displayed is outside the
new range of values. However, you could do that as well by calculating
what the value should be and using

widget_control, state.labelid, $
set_value = string( new_label, format = state.format )

My apologies for the quick posting earlier which incorrectly said
to change the actual slider min and max limits.
