SWT does not support per-pixel translucency on widgets currently. Only on images. It would be a good adding to the toolkit.

Does SWT support per-pixel translucency (as in Swing in 6u10-6u14 and 7)? I've been trying to create a translucent top-level shell with soft rounded corners (as in [1]), but no luck. Using NO_TRIM on the Shell removes the decorations, but setRegion() only installs one-bit transparency on the shell pixels. I've tried using a NO_BACKGROUND Canvas with a custom PaintListener that sets alpha 128 on the GC of the passed event, and when it comes up, it looks right (translucent canvas on top of the underlying window). But once i start dragging the shell, it still has the "snapshot" of the original location of the screen. And setting alpha on the Shell itself is not what i'm looking for - i want to have different alpha on different parts of the shell.

I would love to see your (swing) demo running in an SWT environment and discuss in this list how Trident might fit into e4.

I've been following this list for a few months, and i haven't seen any (significant) discussion on this topic. I've recently released the first official version of Trident animation library which has built in support for both Swing and SWT - including automatic support for threading rules and additional UI toolkit-specific features. The overview of support for UI toolkits is at [1], and examples for SWT can be found at [2]-[4]. Is this something that would be of interest to the e4 project? The core Trident capabilities can be used to built more complex animations such as layout transitions, window fades, cross fades etc - as shown in the demo Swing application at [5]. And while the demo is in Swing, i am going to port it to SWT as well in the next few weeks.
