multi-touch

I have a UITableView: Cell 1: Button 1->push to view controller A Cell 2: Button 2->push to view controller B It works fine. However, when I try to hold and press two buttons at the same time, my app receives following warning: nested push animation can result in corrupted navigation bar. Finishing up a navigation transition in an unexpected state. Navigation Bar subview tree might get corrupted. How should I disable multi click button on cell ? You just need to disable the button while pushing to another View Controller. You can create category of UINavigationController for pushing to another

I need help I'm trying to zoom to mapview by getting users multi touch points (firstly 2 finger touch) I know there is setMultiTouchControls() function but this is not what I want to do. I tried to explain with a picture :) it was easier than writting; The black bold arrows show the fingers' movement directions. The same situation can be considered for opposite directions.(zoom in) Ismail Sahin Finally, In osmdroid 3.0.10 this feature had been implemented. mapView.setBuiltInZoomControls(true); mapView.setMultiTouchControls(true); 来源： https://stackoverflow.com/questions/15159544/two-finger-or

Has anyone run across a good implementation in library or package form that implements MULTI touch processing that includes pinch-zoom, rotate, two finger swipe etc. and is relatively easy to extend? I wrote the code for pinch-zoom and two finger swipe, but it's been awhile and I am tired of relearning this somewhat messy API with all of it's gotcha's every time I need to extend my actions. The best I can find at this point is Howto use - Multi Touch Controller from Luke Hutchison's source code If anyone else has something better please post! 来源： https://stackoverflow.com/questions/10454570

I have a WPF 4 application where I have implemented Drag and Drop using the standard DragDrop.DoDragDrop approach, but Im doing it using touch instead of Mouse events. My XAML for my Grid (that Im dragging) is as follows: <Grid x:Name="LayoutRoot" ManipulationStarting="ManipulationStarting" ManipulationDelta="ManipulationDelta" ManipulationCompleted="ManipulationCompleted" IsManipulationEnabled="True"> <!-- children in here --> </Grid> Now the code behind is like this: private void ManipulationStarting(object sender, ManipulationStartingEventArgs e) { e.ManipulationContainer = this; e.Handled

On Android, it is possible to check programmatically if the device supports multitouch or not wth http://developer.android.com/reference/android/content/pm/PackageManager.html#FEATURE_TOUCHSCREEN_MULTITOUCH . Is it also possible to check exactly how many fingers the device can recognize in multitouch? E.g. from what I know, a 2-finger multitouch is supported starting with 2.x, but 3-finger multitouch from 4.0. But our customer reports having some new devices with 4.x which still don't support 3 fingers, which makes a simple check against the version of Android OS useless. A possible solution

I have developed an Android application that is handling multitouch in a view. I basically track the several MotionEvents that can occur like ACTION_UP, ACTION_MOVE, ... My overwritten onTouch method in the View class looks like this: public boolean onTouch(View view, MotionEvent event) { int action = event.getAction() & MotionEvent.ACTION_MASK; if (action == MotionEvent.ACTION_DOWN) { float x = event.getX(); handleTouchStart(view, x); } else if (action == MotionEvent.ACTION_UP) { float x = event.getX(); handleTouchEnded(view, x); } else if (action == MotionEvent.ACTION_POINTER_DOWN) { int
