multi-touch

I am using Pep.js for kinetic drag on multi-touch, but my drag events are not being registered because when I try to drag an object in the safari, on iOS, window the window itself moves and follows my drag. How can I prevent the browser window from following my drag so that the <div> in my webpage can be dragged? Here is the webpage in question: http://goo.gl/TsHgh . Click on the link and a <div> slides in, it is that div that is draggable. It works on desktop browsers, but can not be dragged on multi-touch because safari moves the window along with my drag. I have found this solution while

As a bit of background - Windows has a facility for Touch/TabletPCs whereby it shifts the position of popups/menus depending on your "handedness" (to prevent the menu appearing under your hand). Essentially what this does is if you are set to "right handed" (which it seems to default to once you've connected a touch device), every popup you open is artificially kicked to the left - this causes massive layout issues where we try and line up a popup with the item it "popped up from" : Tablet PC Settings set to Left handed - no artificial correction from Windows Tablet PC Settings set to Right

How does one implement pinch gestures on the iPhone? I'm familiar with using touch events on the iPhone but I'm extremely lazy and don't want to re-invent the wheel for something as widespread as PINCH gestures...Source code or links thereto would be helpful. Brock Woolf You need to implement it yourself using some basic math. (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event; (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event; Those are the delegate methods that you need to implement in your application. You need to get the distance between the two touches, then

In iOS is there anyway to prevent a UIView containing multiple buttons (siblings) from being simultaneously from being touched? For instance, two non-overlapping buttons that are side by side can be tapped at the same time with two touches. Set UIView.exclusiveTouch. Gajendra K Chauhan You can also use below method. If you have two buttons or more, to prevent multiple push at a time. for e.g, [Button1 setExclusiveTouch:YES]; [Button2 setExclusiveTouch:YES]; Set this method in your viewDidLoad or viewWillAppear for(UIView* v in self.view.subviews) { if([v isKindOfClass:[UIButton class]]) {

I have multiple buttons, if user touches 2 or more buttons and releases simultaneously, I want to give the action of just one button. How can I do that. Thanks in advance for your help.. Set exclusiveTouch property for all buttons to yes . If that is not working, you might have to disable all other buttons when the user is tapping on a particular button and enable it once that particular action is completed. Try setting your view's multipleTouchEnabled property to NO . 来源： https://stackoverflow.com/questions/13428439/ios-sdk-stop-multitouch-functionality

The documentation say this about that: A gesture starts with a motion event with ACTION_DOWN that provides the location of the first pointer down. As each additional pointer that goes down or up, the framework will generate a motion event with ACTION_POINTER_DOWN or ACTION_POINTER_UP accordingly. So i have done the override of onTouchEvent function in my activity: @Override public boolean onTouchEvent(MotionEvent MEvent) { motionaction = MEvent.getAction(); if(motionaction == MotionEvent.ACTION_DOWN) { System.out.println("DEBUG MESSAGE POINTER1 " + MEvent.getActionIndex() ); } if(motionaction

i'm developing a application for gestures recognizer for iPad and i want to disable the default gesture recognizer of the iOS. When i ask a way do disable the gestures recognizer is using my own application, so i need a way using some functions of the api and not using the settings way. The four- and five- finger gestures are not officially part of iOS, and may never be. Though it would be best to figure out an alternative, you should be able to use these gestures for now and not fear conflicts (save on the iPads of developers who have specifically turned on this feature, whose users know that

Which one should I use? I'm only using Windows 8.x, so I don't care about the fact that WM_POINTER is not backwards compatible with Windows 7 etc. I also don't care about gestures; only about raw touches. WM_POINTER's only clear advantage seems to be that it unifies touch and mouse input (but that's easy to work around with WM_TOUCH because mouse events can be checked with GetMessageExtraInfo()). Ease of use is also not an issue; I've been using WM_TOUCH already and I'm just wondering if I should switch to WM_POINTER. My overriding concern is latency and efficiency (game-related application).

I have a Samsung LD220Z multi touch monitor, and when I'm experimenting with some WPF and touch features the touch events arent firing. The mouse down event seems to be firing however. Does this mean that I have to take into account that not all touch screen behave the same, and how do I get the touch inputs on my screen? I've tried the Windows 7 Touch pack that microsoft released. And the multi touch features seems to work there. Any suggestion on how to proceed with this? Event touchstart WORKS but touchend not. You can use onmouseup="SOMEfun()" Even the Samsung Galaxy 3 is a problem with
