Hello,

my problem is that swt does not accept those classes.

java.lang.SecurityException: class “org.eclipse.swt.widgets.GlassAwareShell”’s signer information does not match signer information of other classes in the same package

Absolutely brilliant post! I’m buzzed at being able to use Aero Glass.

Unfortunately, using the present release version of SWT, many of the Shell and Composite functions are private or final, and therefore cannot be reached. Is there any way of implementing GlassAwareShell without modifying the original SWT classes?

Do you know how can I disable ‘Desktop Composition’ for SWT application? (in window7 & vista)

Thanks for quick reply, Łukasz!

Hmm, well.. I have Intel Core 2 Duo with 8GB of RAM and I still have a problem with this artifact. But if I unchecked ‘Enable desktop composition’ in visual-settings of my w7 - everything works fine! :)
Thanks for your answer, I’ll try experiment with WM_RESIZE may be it will give a some result.

Regards,
Dmitry.

Hi Ch3D!
Yeah, I’ve seen the black parts when resizing, but only on rather slow machines, or on VMware. Similar artefacts can be seen when you resize Chrome Browser window (while having Glass and default skin for Chrome). ATM don’t know how to fix that, maybe some workarounds near WM_RESIZE message, but that’s just wild guess.

Hello Łukasz!

Have you ever faced with a problem of black parts of shell when resizing the window?

Naw, I could imagine a constant SWT.GLASS or SWT.AERO that would extend the glass all the way into the shell. Controls that did not set the background (ie. left the default) would then have the glass shining through.

Alternately, there could be an API on Shell that extended the glass into the client area of the shell.

Hi Steve!
For me, and for application I’m working on my in spare time, Vista (and Windows 7) glass style is very important - I’m trying very hard to create very rich user interface just by using as much as DWM gives me.
Re double buffering and animation. I haven’t got to the point where I use widget that has animation, but since DWM provides methods to animate, they could be used with double buffering.
Re visibility. I see and understand your point, it was just a thought. Either way, having this hook mechanism would be awesome thing, if you have it somewhere to test it I would be happy to look at it :-)

Last thing, I may be biased by Vista/7, but this kind of stuff presented here is and (probably) always be Windows specific and applications that makes use of it would have to manage that as well (fragments if it is plug-in development, separate binaries for applications - just like swt does)
