multiple touches: touchend event fired only when a touchmove occurs

∥☆過路亽.° 提交于 2019-12-04 01:38:44
I would like to add some multitouch features to my javascript application when it is accessed from an ios device (and maybe android later). I want to provide a shiftkey-like functionality: the user may hold a button on the screen with one finger, and while this button is pressed, the behavior for a tap action on the rest of the screen is slightly different from the classic tap. The problem i'm running into is that i do not receive any touchend event for the tapping finger unless a touchmove is fired for the first finger holding the shiftkey button. Because the screen is very sensitive,

Detecting pinch in Android

I would like to handle pinch events in my Android application to zoom in and out. I believe Android 2.0 has multi-touch functionality, and heard that Android 1.6 might or might not support it depending of the device. What's the best way to detect pinch events, while degrading gracefully for devices that don't support it? I'm targeting Android 1.5 upwards. Damian A great article by Ed Burnette (Hello Android Author) on multi touch (including pinch zoom) can be found here: http://www.zdnet.com/blog/burnette/how-to-use-multi-touch-in-android-2/1747 Here's an article on the Android developer blog

Multi-touch detecting & differentiating - Cocos2d for iPhone

I would like to know how to detect and differentiate between touches in a multi-touch view. I have read about a "hash" code, but I don't understand how to use it. I want to know when two of my Sprites are touched at the same time, like as if pressing a chord on two keys of a piano. [EDIT] Here is an example of what I have for my ccTouchesBegan: - (void) ccTouchesBegan:(NSSet*)touches withEvent:(UIEvent*)event { NSSet *allTouches = [event allTouches]; int validTouchCount = 0; for (UITouch* touch in allTouches) { BOOL touchIsValid = FALSE; CGPoint location = [touch locationInView: [touch view]];

Is it possible to get a popup to ignore MenuDropAlignment in a WPF / Touch app?

问题 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

How to bring up the Windows 8 on-screen keyboard in a desktop app

I have a fullscreen DirectX desktop app, and would like to display the on-screen keyboard when the user taps a textbox in my game. Is there a way to do this while in fullscreen mode? Severin Stampler Executing osk.exe will pop up the more old-fashioned on-screen keyboard. The Windows 8 touch keyboard will pop up by executing C:\Program Files\Common Files\Microsoft Shared\ink\TabTip.exe I just figured that out, since I'm working on a fullscreen desktop app that is running on a tablet PC without keyboard attached. Severin. Same answer as Severin Stampler but in order to find the correct path

How to do pinch gestures on the iPhone?

拜拜、爱过 提交于 2019-12-03 06:10:10
问题 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. 回答1: 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

问题 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. 回答1: Set UIView.exclusiveTouch. 回答2: 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

iPhone: Tracking/Identifying individual touches

问题 I have a quick question regarding tracking touches on the iPhone and I seem to not be able to come to a conclusion on this, so any suggestions / ideas are greatly appreciated: I want to be able to track and identify touches on the iphone, ie. basically every touch has a starting position and a current/moved position. Touches are stored in a std::vector and they shall be removed from the container, once they ended. Their position shall be updated once they move, but I still want to keep track
