Hi Kirill - The URL we gave before was the path in CVS to check out the SWT e4 project: dev.eclipse.org:/cvsroot/eclipse/e4/org.eclipse.e4.swt/bundles/org.eclipse.swt.e4. Here is a browsable URL:
http://dev.eclipse.org/viewcvs/index.cgi/e4/org.eclipse.e4.swt/bundles/org.eclipse.swt.e4/ The animation API that we put together makes use of the available OS animation support (so we address points 2 and 3). What we were trying to get at is that win32/gtk controls do not provide certain properties we believe are necessary to enable more advanced animations (alpha, transformations etc) nor do they provide any native animation timeline support. We could see an animation framework where the framework would make use of the OS timeline support whenever available and use an emulated timeline for those platforms which do not have any support. We don't see why Trident could not be used however we always prefer to make use of OS provided support where available (as far as timeline support). For the more advanced properties, you need the OS support. - Silenio & Bogdan Kirill Grouchnikov <[email protected]> Sent by: [email protected] 07/26/2009 12:33 AM Please respond to E4 Project developer mailing list <[email protected]> To E4 Project developer mailing list <[email protected]> cc Subject Re: [e4-dev] Animations in e4 Hi Silenio and Bogdan Thanks for the information. I am interested in looking at the current sources, but having no prior experience in the e4 project structure, i'm not sure where is the link pointing to. Do you happen to have a full URL to a browsable / downloadable version of the source repository? Another question that i have - and perhaps it will be clarified after seeing the code. Suppose the application has a button callback that adds a new control to the form. In the spirit of transition animations, this control slides in from one of the sides and is faded in while it moves. Here, i see three distinct layers: 1. The application layer that decides what needs to be animated. 2. The animation layer that tracks all registered application animations and at every pulse calls the relevant methods on the components (alpha / bounds / ...). 3. The UI toolkit that supports changing these properties to be reflected on the screen. Trident aims to be only the layer number 2. From what you have described, it appears that you are mainly talking about the layer number 3 and how OS toolkits differ in their support of changing the specific component / window properties. If this is true, i don't understand the sentence about win32 and gtk not supporting the animation. Perhaps you're talking about win32 / gtk controls not supporting custom alpha channel? Because all the animation engine is doing (at least in my view) is to change the component property every once in a while - hopefully often enough to provide the appearance of smooth change - and it's up to the native UI toolkit to support those properties. If i am wrong in my reading, please correct me. To clarify Trident's place in the animation "lifecycle", here is an example from fading in a Swing window: Window window = ....; // new JFrame(), for instance Timeline windowFadeIn = new Timeline(window); windowFadeIn.addPropertyToInterpolate("opacity", 0.0f, 1.0f); windowFadeIn.play(); Once Timeline.play() is called, Trident will call the Window.setOpacity() API with values going from 0.0f to 1.0f - asking the UI toolkit to change the opacity of the window. So my question about animations in e4 is about the animation engine as the "controller" that asks the native toolkit to change the widget properties (alpha, bounds, ...). I would imagine that you already have something in place, and i was wondering whether Trident can be considered to be used for that part.

The API has been implemented (to varying degrees of completion) on WPF, Cocoa, Flex and Dojo. Currently there is no animation support on win32 and gtk. QT could be an option since it provides an animation API. GTK 3.0 may provide such an API in the future. When it comes to animation, there are a few features that the core widgets need: alpha, transformation and bitmap effects. The platforms we have prototyped all have that support. If that kind of support is not available in the core widgets, you are restricted to animating custom draw widgets. The prototypes are in the folders Eclipse SWT Animation and Eclipse SWT Effects under: dev.eclipse.org/e4/org.eclipse.e4.swt/bundles/org.eclipse.swt.e4 Silenio and Bogdan Kirill Grouchnikov <[email protected]> Sent by: [email protected] 07/22/2009 06:19 PM Please respond to E4 Project developer mailing list <[email protected]> To E4 Project developer mailing list <[email protected]> cc Subject [e4-dev] Animations in e4 Tom, Since Trident has its own dev mailing list, and now there is (or going to be, hopefully) a discussion on the e4 dev mailing list, i would rather not fragment this thing even further by splitting some of the dialog into yet another list. My general question about e4 is - what are the plans for animation capabilities in e4? Is this being incubated in CWT / Nebula? Is this being floated at a very generic level with no concrete discussions? Or perhaps this is being discussed in bugzilla?
