Let's assume easiest set or whatever matlab assumes when it determines CurrentObject of the figure. well... it surely uses the position of the last m-click... i guess it's obvious that CSSMers cannot really follow your problem... you really should be more specific about what you want... us

But you're right, I should be more specific: Prototype: H = PIXEL2HANDLE( HF, X, Y ) Given a figure HF, and the pixel coordinates X, Y relative to the lower-left corner of HF, identify the object H such that if there was to be a mouse click on that pixel coordinate, that object would be the "CurrentObject" of the figure HF. If there is no such object, H is empty. > well... it surely uses the position of the last m-click... So as you can see (I hope!) that the the crux of the question is we want to be able identify the object *without* the "m-click".

But seriously, that is not the answer -- and probably will not work optimally in general, e.g. in my case, which is to create an interactive plot interface via hovering over the figure sort-of-thing. -- We don't want to click or simulate a click. Actually we don't even want to update the CurrentObject of the figure.
