Hi,
The recently implemented (1.1M2) SWT graphics classes such as ImageData
are in org.eclipse.swt.internal.graphics, whereas in SWT they are in
org.eclipse.swt.graphics. Is this a temporary move, intended to
indicate that the classes are ready for use inside RWT but should not
yet be used by application code? If the move is intended to be
permanent can you please explain the rationale?
Also, is there a plan to implement GC for SWT drawing capabilities?
Thanks,
Ryan

Hi,
The resource handling in RWT is different than in SWT. Reasons for this
are e.g. that RWT resources are not provided by the operating system and
that they are shared over session boundaries. Images for example are
simple references to files available for the browser in a download
directory. So there's no need to load image data into memory. ImageData
is used to create overlays for decorations for example. We reuse the
original ImageData implementation to do so. It is a thought to provide
this as API, but it is not clear at the moment when an how to do this,
since we have to provide a way that works well with the RWT resouces
handling and a reasonable approach in respect to SWT compatibility.
We did and we are doing investigations on how to provide GC drawing
capabilities, but this is a difficult topic. So there is no schedule for
GC at the moment.
Ciao
Frank
