Brendan -- and anyone else implementing drag functionality -- as a general rule, the way you should implement drag functionality is: - add a mousedown handler to the thing you want to drag. - on mouse down, add a mouse move and mouse listener handler _to the systemManager_, _in the capture phase_. - on mouse move, update your data. Keep in mind that the mouse event x/y for mouse move will be in systemManager coordinates, so either use mouseX/mouseY off of the original target, or convert all coordinates to global before doing any computations. - on mouse up, remove your move/up handlers _from the system manager_ during _capture phase_. That will fix the problem with your current example where the drag breaks when you move the mouse too quickly. Ely.

If your drag updates your slider, then you can use the properties in the Slider class for snapping to values. Changing the horizontalGap, dividerAffordance, etc... in the HDividedBox on the bottom chart should get the visual appearance you want. The one thing I was pondering over was dragging the main chart (like google finance does). Ely, can you shed some light on the best way to accomplish this?

Use a two-button horizontal slider, and draw a transparent rectangle over the chart based on the sliders values. -- Tom Chiverton Helping to enormously industrialize cross-platform e-tailers On: http://thefalken.livejournal.com <http://thefalken.livejournal.com> **************************************************** This email is sent for and on behalf of Halliwells LLP.
