digitalmars.D.announce - Official Dub package for DWT

This has been long overdue but I would like to announce that I've just 
released an official Dub package for the DWT library [1]. For a usage 
example, please see the GitHub page [2].

For those not familiar with DWT, it's a library for creating 
cross-platform GUI applications. It's uses the native drawing operations 
of the operating system. It's originally a port of the SWT Java library, 
it's a complete port and contains no Java or JNI code.

A couple of other changes are:

* All the previous Git submodules have now been inlined in the 
main/super repository [3]
* Proper testing on both Linux and Windows has been added
* Separate tool for building all the snippets
* Bumped the minimum requirement of the compiler to DMD 2.078.1 (I'll 
probably add support for LDC soon)
* Officially removeed any support for building with D1

Thanks for this effort. I looked at DWT a while back but settled 
on GtkD because it was easier to build. Either way, I will have 
to revisit this library and give it another go in my new project.

Looking at the examples I imagine it wouldn't be too difficult to 
use WindowBuilder for SWT and port the generate Java code across 
to DWT.

bye,

Yeah, I don't think that would be too difficult.

Great to see this project on Dub. It was always fairly easy to 
build, but including it in Dub will surely help its adoption.

Can you explain how the EPL license works? I am not familiar with 
that license. Is DWT and anything using it considered a 
derivative work off Eclipse? Do I need to share source for my 
project if I use DWT in my project?

 From tldrlegal[1]:
"This license, made and used by the Eclipse Foundation, is 
similar to GPL but allows you to link code under the license to 
proprietary applications. You may also license binaries under a 
proprietary license, as long as the source code is available 
under EPL."

This doesn't really explain much. It's confusing. It's similar to 
GPL. So if I release an app using DWT, I need to release the 
sourcecode for my app? Or do I only need to release the code for 
DWT (if I did any changes to the sourcecode).

Not a lawyer, but it doesn't appear to really target libraries 
and is more directed to a complete application. The way it is 
written suggest that DWT would be a derived work and any changes 
to it will also be derived and need to forward the EPL license.

However it makes no specific statements about using libraries as 
part of your code, which would suggest that the code outside the 
EPL library is not considered "the EPL Program" and thus not a 
derived work.

On Linux it should just work if you have a 64bit system. On Windows I 
guess you would run Dub with "dub --arch=x86_64", if it doesn't already 
default to 64bit.

This is awesome. I don't use GUI too much with my D programs, but 
I've had one lingering with DFL for a while now.

It took a little bit to get familiar with this framework again, 
but I think the conversion has been totally worth it (even seems 
to have made my application faster).

I'll point out that this is definitely a lower level library than 
I usually see/use.

I also hit only one documentation issue due to this being 3.4 and 
not 3.7 or later, but that didn't look like it would be a normal 
hiccup.

Anyway, thank you for getting this to work with DUB as that 
simplifies my build.

This is great, thanks!
Any plans to make it link with gtk3 instead of 2? I remember gtk2 
had issues with HiDPI support.

DWT is a port of the Java library SWT. This particular version, 
3.4, of SWT only supports GTK2. Later versions of SWT do support 
GTK3. The current port is a manual port, but I'm working on a 
tool to automate porting the code. I will not update DWT until it 
can be automated.
