I am trying to detect left,right swipe events on the screen using hammer.js.
Currently its detecting swipe action over entire screen area since i am passing the main content div class.I've created an overlay div covering half of the screen area and its class is passed when hammer is initialized.So now the swipe is working fine over that area ,but all other pointer events to content below the overlay is blocked.
Is it possible to pass all other pointer events to underlying divs except the swipe events ?
Assuming I understood your problem description correctly and re-phrasing it as follows: You want to use an additional recognizer along with your existing swipe(left, right) events.
You can add a new event on the same manager instance that you had already created [1]
Even if you've separated out both the events and still want to execute them simultaneously then use recognizeWith [2]

Im new with Angular and I am creating a chat application with the same facebook behavior. I need each chat box to appear at the bottom of the screen (right now they appear in the middle of the screen) and as a user is selected the box that comes out You should leave next to the one that is already there.
I also need that when those chat boxes occupy the entire space, something similar to the image attached is shown, a button where the first boxes that you select come out so that you can select and resume that conversation. In the following link I have my application working. Could someone help me? The application code and the demo can see it here.
The image of the behavior that I want is the following:
Our goal is to have two button-like views in our React Native game. They will each consist of a View wrapping around some animated image or alike. The views should be touchable at the same time.
This means: We want to trigger some action on the onTouchStart (like add a symbol to a text) and change the state of the view while it is pressed (for example to change the image in the background or something like that).
Using onTouchStart did not work, since on Android (and only there) we had a Problem: When keeping the first button pressed, pressing the second button with a second finger caused the first callback to trigger, not the second one.
How should we implement this correctly without messing with native code?
I am binding a hidden DIV element with Google maps, when the DIV element is being shown. The user can show and hide the DIV multiple times. I want Google Maps to be loaded and bound to the element only once, and not everytime the DIV is (hidden and) shown. Is there any API method from Google Maps which will check if the element is already bound to a Google Map object?
map.getDiv()
gives you the current div the map is bound to.
Hope this is helpful. You can easily implement the functionality.
Initialize the Map once. Then just hide and show the div as per requirement.
Just make sure to Initialize the Map when the Div is visible or else you will run into problems of improper map rendering. (at least this happens if you have bootstrap).
I am working on a Touchscreen application.
For this I Need to Change the current window if user clicks on the Screen (Position doesn't matter).
For this I Need a to make my button (which is currently the same size as the current window) invisble, so user can see the Labels etc.
Any idea how to make Buttons invisible in PyQt4?
I recommend you not use a button to do this. Instead, either put an event filter on the QApplication instance, so any widgets in your window get events only if you determine they should; OR put a transparent panel widget over the touch area, with a mouse click event handler for that panel. Either method supports arbitrary complexity of widgets inside your touch area (labels and tables to display information etc). Main disadvantage with event filter approach is that all application events (from all threads) will be filtered. This could affect performance (you'd have to test, may not be any noticeable differenc), but it is simpler to implement than the transparent panel.
I have two overlapping images. I touch the topmost image and start moving (touchmove) finger around. All subsequent touchmove events are received by that image. In the middle of this interaction I want the events to go to the image underneath, so that I can move it around instead.
How to change the event source to the image underneath? That is, once an object has started receiving touch events, how do I change the target of those events?
I suspect that Joe Blow is talking about handling touch events in the context of a native iPhone app built with Objective-C.
Eric's question is about handling touch events in Mobile Safari with JavaScript.
I could be confused though...
