Re: [platform-swt-dev] Patch for SWT_AWT
|
Veronika,
The code you checked in doesn't compiler under 1.4, as it uses the
unpublished and now removed sun.awt.DrawingSurface class (see Java 1.4.0
docs). The replacement is the published, new JAWT interface to AWT for
native programs. What Matt's code does is to use this new interface in
the new_Shell method to get the needed hWnd to the drawing surface.
In order to have the same Eclipse installation run with either Java RE,
a version check has to be added (together with introspective method
invocations).

Thank you for the patch.
We have looked at the code and it seems fine but it does not appear to
do anything different from what we are already doing in Java code.
We found a problem with our Java implementation in JDK 1.4 and have
fixed this so you should be able to run on JDK 1.4 using the latest
integration build (20020501-I).
We will hang on to your patch but we will not be releasing the changes
until after 2.0 when we have more time to test on the various platforms
and examine the issues.
Thank you,
Veronika

I have tested with JDK 1.3 and 1.4 and Windows 2000. All of the
knowledge/code was taken from the following page, which is included in
the JDK 1.3 docs:
_http://java.sun.com/j2se/1.3/docs/guide/awt/AWT_Native_Interface.html_
The code only works with Windows because (a) I don't know too much
about X and (b) I don't have Linux installed anywhere. It shouldn't
be too hard to port to X if there is a way to create a Shell from a
Drawable(?).
The only quirk with the code is the part that loads jawt.dll(the
loadJawtLibrary function). Duringtesting I found that the code failed
to load jawt.dll when the code was run using the invocation API. When
I ran the code with java.exe it worked fine. I'm not sure if it's
something that I am doing wrong, but I haven't figured out a way around
it.
Matt

Cool. What JDK versions does it work with and what OS platforms have
you tested it on?
The file swt.c is generally for native OS calls so we would probably
keep the AWT integration native stuff seperate as I assume it is
platform independant.
Send the patch to this mailing list and we will check it out. Before
sending a patch, please be sure that it does not include any code that
is copied from AWT source that is not publicly available and that it
does not make use of any knowledge of AWT that is not publicly available.
Thank you,
Veronika

I have version of the SWT_AWT class using JAWT that I wanted to
contribute.
Part of the class is implemented natively and I'm not quite sure how that
fits into the Eclipse project. Would the native part be patched into the
swt.c file? Right now I have it in its own file.
Thanks,
