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

Hi 

Perhaps off topic (and belonging in the SWT list).

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. 

Thanks
Kirill

Kirill,

 

I have been following both the SceneGraph and your Trident activities in the last months. I would love  to see your (swing) demo running in an SWT environment and discuss in this list how Trident might fit into e4.

 

Best regards,

 

Kai

Hi

I have a question about slide 4 - about deferring the advanced animations in SWT.

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.

Thanks
Kirill

I have prepared the docu-ware required by the Eclipse development process for the e4 0.9 release. I have attached a draft of the slides here for e4 committers to review. Please let me know of any errors or ommissions.
