Generating events for gesture-controlled websites

由 安稳与你 提交于 2019-12-07 04:49:40
问题 I am very happy that I got the opportunity to work on a website that is gesture-based. I have a few inspiration for this: link I visited lot of websites and googled it, Wikipedia and gitHub also didn't help much. There is not much information provided as these technologies are in nascent stages. I think I will have to use some js for this project gesture.js (our custom javascript code) reveal.js (Frame work for slideshow) My questions are how come gestures generate events, how does my

由 早过忘川 提交于 2019-12-06 23:50:44
问题 When I want to animate the UIImageView , the UITapGestureRecognizer added to it can not work. WHY??? -(void) testTap:(id)sender { NSLog(@"Test tap..."); } -(void) testSlide { UITapGestureRecognizer* testTap = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(testTap:)] autorelease]; testTap.numberOfTapsRequired = 2; UIImageView* imageView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"tip_slide"]] autorelease]; [imageView setFrame:CGRectMake(40, 40, 200, 200)]

ios7 new pan gesture to go back in navigation stack does not clear tableview selection

由 天涯浪子 提交于 2019-12-06 21:28:46
问题 I have a Notes-like app: uitableviewcontroller showing up individual notes by pushing them onto navigation stack). And I decided to use an ios7 Back button and a pan gesture recognizer coming with it. My only modification is removing text from the button by setting navigationItem title of the from-controller to an empty string before pushing the detail-view-controller, as it is advised at https://stackoverflow.com/questions/18870128/ios-7-navigation-bar-custom-back-button-without-title The

How to rotate to another face of 3d cube when swiped right

由 心不动则不痛 提交于 2019-12-06 10:23:54
I created a 3d cube using SceneKit and added a gesture to recognize swiping right. But, I do not know how to rotate the cube to another face when swiped right. I do not want the cube to rotate continuously when swiped, only moving to another face that is on the right side. Sorry for any confusions. Here is my code where I created cube: import UIKit import SceneKit class ViewController: UIViewController { // UI @IBOutlet weak var geometryLabel: UILabel! @IBOutlet weak var sceneView: SCNView! // Geometry var geometryNode: SCNNode = SCNNode() // Gestures var currentAngle: Float = 0.0 // MARK:

Kinect Grip Gesture for Click

由 三世轮回 提交于 2019-12-06 06:22:17
I'm using kinect V2.0. I need to perform click using grip gesture. Is there a way to handle the Grip gesture in V2.0 like AddHandPointerGripHandler in V1.8. In Microsoft Kinect SDK v2.0, the Body class includes two properties: Body.HandRightState Body.HandLeftState Both these properties are instances of the HandState enumeration, which specifies if the hand is: Closed (and you can detect this to trigger the Grip gesture); Lasso (which means that the hand is closed in a fist, except for a finger pointing upward) Not Tracked (the hand state is not tracked) Open (the hand is open) Unknown If you

In Flutter, how can a positioned Widget feel taps outside of its parent Stack area?

由 本小妞迷上赌 提交于 2019-12-06 06:02:30
A Stack contains MyWidget inside of a Positioned . Stack( overflow: Overflow.visible, children: [ Positioned( top: 0.0, left: 0.0, child: MyWidget(), )], ); Since overflow is Overflow.visible and MyWidget is larger than the Stack , it displays outside of the Stack , which is what I want. However, I can't tap in the area of MyWidget which is outside of the Stack area. It simply ignores the tap there. How can I make sure MyWidget accepts gestures there? This behavior occurs because the stack checks whether the pointer is inside its bounds before checking whether a child got hit: Class: RenderBox

Android: Create a swipe gesture event programmatically

由 冷暖自知 提交于 2019-12-06 02:09:32
问题 I've been trying to find an answer for this specific case on Google and amazingly couldn't find it anywhere (there's just answers about detecting, not creating, swipes). I want to actually 'run' a simulated swipe from right to left on the screen (doesn't matter where, but ideally from the right edge to the left). I tried something like this, but I get a NPE: final float viewWidth = view.getWidth(); TouchUtils.drag(null,viewWidth,1f,0f,0f,1); The reason? I need to force a swipe to the next

How can I implement gesture recognizers in OS X?

由 烂漫一生 提交于 2019-12-05 17:48:11
问题 I have done quite a bit with gesture recognizers for iOS, but I am now doing work in OS X, and I am lost. I want to duplicate the functionality that exists like in Finder where you can two-finger swipe (on your magic mouse) to go back/forward through a directory tree. I have an NSWindow based app that looks very similar to Finder. I have used apps before that allows you to build your own gesture recognizers so I know it is possible to do it, but I don't see any documentation on it. What do I
