Touch events available in Safari?

走远了吗. 提交于 2019-11-28 09:42:16
问题 A friend and I were discussing Mozilla's latest touch support and got on the question of what Safari provides for this. Searches seem to turn up nothing. Do you know of anything that provides touch events to Safari on desktop, either via multitouch trackpad or direct screen interaction (I guess a Windows multitouch environment would be the only relevant case here.)? 回答1: No, there is currently no support for touch events in the desktop version of Safari. According to this documentation it is

Is there a way to trigger gesture events on Mac OS X?

Is there similar low level function for multitouch events? Rok Your suggestion is not working. I've tried this code: - (void)rotateWithEvent:(NSEvent *)event { NSLog(@"ROTATE"); } -(IBAction)button:(id)sender { CGEventSourceRef eventSource = CGEventSourceCreate(kCGEventSourceStateCombinedSessionState); CGEventRef event = CGEventCreate(eventSource); CGEventSetType(event, NSEventTypeRotate); CGEventPost

问题 Recently I'm making an app that can drag multiple objects at the same time. I had tried to use UIPanGestureRecognizer to get the coordinates of finger touches, but I couldn't know which touch belongs to which finger. I need to support four fingers panning simultaneously without interfering with each other using Objective-C. I had searched for the soulution for a while, but the answers they show didn't work for me. Any help would be appreciated. 回答1: I've struggled with the same problem for

How to develop multi-touch applications in Java?

旧巷老猫 提交于 2019-11-28 05:58:01
Anticipating the day when multi-touch interfaces become more pervasive, are there libraries in Java that can be used for developing touch applications? I'm looking for interfaces similar to MouseListener / MouseMotionListener / MouseWheelListener. The MT4j project has everything you need to develop multitouch applications in java. All the well known multitouch gestures are already built in and can be accessed as simple as listening to mouse events (for example: component.addGestureListener(..)). It also features a hardware accelerated scene graph, similar to JavaFX. You can even simulate

Android multitouch in supported devices

最后都变了- 提交于 2019-11-28 01:54:39
问题 let's say I'd like to have an image view in my app with zoom is it possible to add multitouch event listeners on phones that do support multi touch (API 7+), while on older phones show zoom buttons? Can this be done in a single version of the app or do I need multiple app versions and multiple APKs? 回答1: You don't need multiple APK in this case. You can check availability of the multitouch in the code: if (Integer.parseInt(Build.VERSION.SDK) >= 7) { PackageManager pm = context

Touch Events not working with Google Maps in Angular

我只是一个虾纸丫 提交于 2019-11-28 01:34:55
I am using Google Maps javascript API within an angular application. When using the app in Google Chrome on a regular desktop machine with a mouse, various navigation features (pan/zoom) work in the google maps part of the application just fine. However, when I try to use touch gestures on a windows 8.1 screen, the maps do not recognize any of the pan or zoom gestures. If I pinch to zoom, nothing happens. If I double tap on the screen like a mouse, then maps will zoom in. If I drag with a finger, the browser window handles the touch events instead of the maps div, so left and right navigates

Javascript touch movement, track when user swipes from edges

假装没事ソ 提交于 2019-11-28 00:41:23
问题 I need to track user touch events. I want to track when user swipes from edges. For example when user swipes from left vertical edge I will show a menu, from right edge make an alert, and show another menu when user swipes from top. I couldn't find a similar usage. How can I make this behaviour ? Tracking swipe from edges ? I tried this with hammer.js because I use jQuery, But other libraries (QuoJS, TouchSwipe, Touchy etc.) are ok for me.
