Is there a way to get context image from Composite? [message #1702854] Sun, 26 July 2015 09:05 Go to next message
Eclipse UserFriend
Since Linux does not support transparent Composite, I want to find a
diverting-method:

As I know, everything is drawing: Label is drawing, Text is drawing, Table
is drawing.......
So I think is it possible to get the context image of Composite (with some
controls on it)?

If I can get the context image of composite with some controls on it,
I can draw this image to a MyTransparentComposite, so it looks just like a
transparent composite.

Is it possible?

SWT does support Transparent background for composite from 4.5 onwards release refer: https://www.eclipse.org/eclipse/news/4.5/M5/#transparent-bg
Refer Snippet365: http://git.eclipse.org/c/platform/eclipse.platform.swt.git/tree/examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet365.java

Thanks.

BTW, I do find a way to get the image-copy of composite: gc.copyArea().
