slider("moveTo",value), callback suppression & other effects

slider("moveTo",value), callback suppression & other effects


I'm fairly familiar with jquery, but relatively new to ui. I've been
experimenting with sliders, and have a couple of questions which I'm
hoping the community might be able to help me with:
First - Is it possible to suppress the callback function when the
slider is moved using the slider("moveTo", val) method? According to
the wiki <http://docs.jquery.com/UI/Slider/slider#.22moveTo.
22valueindex> there seems to be no way to do it. I've found some
discussion previously about sliderMoveTo(), which did allow the
callback to be suppressed, but that was fairly old, so may not apply
anymore.
The second question - I've found that if the slider position is
constantly updated (to display the position in an animation, say), the
ability to use select elements is lost, as something seems to keep
stealing the focus from them and closing the menu. Is this expected
behaviour?
Thanks in advance,
Chris
