I am intending to use skia for an app. How to handle events like web input box click, wheel events etc in Skia ? What are the possible events in skia? How to handle events in skia?
React Graphics Library Built on Skia - https://github.com/bridgedxyz/nothing
It'll have Similar api such like Konva React, but built on skia instead. - better performance

I'm developing a mobile website and would like to add gesture recognition to some of the key features of the site.
Is there a suitable javascript library that would allow me to draw a gesture and recognise the gesture as a token I could hook up to an event call?
As an example of this type of functionality in Dolphin see these links;

We're using Hammer.js and it is working great.
"Can't touch this". -- MC Hammer
(See what they did there?)
For simple gesture recognition, there's $1. It's less than 100 lines of code and is written in JS.
I am using the MVVM light toolkit in a WP7 application and I am trying to wire up a canvas element's appropriate event to my view model using the 'EventToCommand' behavior. The event I am looking to intercept is the 'swipe up' gesture.
I have currently tried relaying the 'KeyUp' event but that doesn't behave like I had assumed it would. Is this even possible using behaviors or should I be doing something else? All the events I wire up to the viewmodel using the EventToCommand behavior work fine, but my basic problem is that I can't find an event for a swipe. I'm guessing gestures are handled differently?
What you need is a way to enable a gesture to trigger the behaviour.
Fortunately, Kevin Marshal wrote just such a thing and blogged about it.
Is there a library available to animate and make java GUI look nice, with animations and transitions like jquery does?
something like css hover, make a panel animate, round the corners of panels so that they look more sophisticated... etc. etc.
So far my exploration has taken me to try java css by Ethan Nicholson, which appears to have been discontinued from the java.net site? and does not appear to have been loaded anywhere else.
And then there is the Chet Haase work on the timing framework for animating swing, and other nice stuff using the SwingX framework.
Anyone got any advice on an open source animation library specifically designed for swing components? Or am I dreaming and should I be hauling out the wallet to pay for someone else's hard labour?
Kirill Grouchnikov created an excellent animation library called Trident. More information can be found at http://kenai.com/projects/trident/pages/Home
I have a rich complex Java Swing Application. I would like the multi touch events to be converted into Mouse events for the Swing Applications.
Is there a way to do it without changing significantly the existing Java Application ?
When I did something that sounds similar to what you're asking, I ended up using the java.awt.Robot class to create mouse clicks according to the touch notifications. I was not using mt4j, though, but rather a proprietary multitouch screen's API that wasn't especially mature.
Is it possible to intercept a control's paint event and make it draw in the opengl context?
I dont know if this is possible, but this tends to writing your own gui.
It whould be simpler to use a complete openGl Gui library.

If you're using Qt there's a fun demo showing (working) Qt widgets rendering 3D in an OpenGL context. How useful that is to you depends how how hooked you are on the native win32 controls specifically.
