trackpad

How do I distinguish whether the event -(void)scrollWheel:(NSEvent *)event was triggered by a Magic Mouse or a trackpad? The reason I'm asking this question is because I want to assign a different action to the scrolling event when a trackpad is used because the user can pinch to zoom on the trackpad. On the magic mouse, however, the user can't pinch easily, so I want to use the scrolling function as a substitute for pinching. I can distinguish between a normal mouse and a Magic Mouse using this line: if (([event momentumPhase] != NSEventPhaseNone) || [event phase] != NSEventPhaseNone) However

Is there any way to handle tap from track pad of mac? I need to handle 'tap' and 'click' on track-pad, especially on mac. I tried $.event.special.tap = { setup: function(data, namespaces) { var $elem = $(this); $elem.bind('touchstart', $.event.special.tap.handler) .bind('touchmove', $.event.special.tap.handler) .bind('touchend', $.event.special.tap.handler); }, teardown: function(namespaces) { var $elem = $(this); $elem.unbind('touchstart', $.event.special.tap.handler) .unbind('touchmove', $.event.special.tap.handler) .unbind('touchend', $.event.special.tap.handler); }, handler: function(event

I hava a Java swing application that use a 'pan-able' JComponent to display large data. When the user move the mouse wheel, I listen to these events, and update the content of the JComponent from the scrolled amount. I would like to have a different behavior depending on whether the user is using a classical mouse using a touchpad, as the ones that can be found on modern Mac laptops. How could I detect that the user is using the mouse wheel vs the trackpad to generate the scroll event? I am relying in java 1.6 swing, si I cannot go to javaFX. Story behind the question: I just wanted to add a

In my application, I want the scrolling to happen, only with scroll wheel action from a mouse and not from the two finger gesture on a trackpad. Basically, I am trying to determine if the scrollWheelEvent is generated from the mouse or trackpad, inside - (void)scrollWheel:(NSEvent *)theEvent method. From what I know so far, it seems like there is no straightforward way to accomplish this. I tried a work around of setting a boolean variable to true and false inside -(void)beginGestureWithEvent:(NSEvent *)event; and -(void)endGestureWithEvent:(NSEvent *)event; But this is not a solution because

Is there any way to detect if the client is using a touchpad vs. a mouse with Javascript? Or at least to get some reasonable estimate of the number of users that use touchpads as opposed to mice? In the general case, there is no way to do what you want. ActiveX might allow you to see and examine USB devices, but in the best case, even if that is somehow possible, that limits you to IE users. Beyond that, there is no way to know. You might be able to discern patterns in how (or how often) a touchpad user moves the cursor versus how a mouse user might move the cursor. Differentiating between

I have created a site where users are able to scroll through a gallery using mouse scroll or arrow up/down. It is working like I want it to, and changing one image pr scroll when scrolling with a mouse. But if the user is scrolling with a trackpad it is almost impossible to scroll a single image at a time. So my question is: Is there a way to check if the user is scrolling by trackpad, and then changing the behavior of the scrolling, so it becomes less sensitive, and thereby easier to scroll a single image at a time? I am not very good at jquery, my solution so far has been put together from a
