digitalmars.D.dwt - Compiling the hello world example fails (2)

Ubuntu 13.04, x86

I've followed this instruction: 
https://github.com/d-widget-toolkit/dwt

Everything was ok, no errors.

Then I've tried to compile hello world:

$ dmd test.d -I/home/virtualbox/dwt/imp 
-J/home/virtualbox/dwt/org.eclipse.swt.gtk.linux.x86/res 
-L-L/home/virtualbox/dwt/lib -L-lorg.eclipse.swt.gtk.linux.x86 
-L-ldwt-base

/usr/bin/ld: cannot find -lorg.eclipse.swt.gtk.linux.x86
/usr/bin/ld: cannot find -ldwt-base
collect2: ошибка: выполнение ld завершилось с
кодом возврата 1
--- errorlevel 1

With -L--verbose flag:
http://pastebin.com/9tavXU96

There you can see that the linker tries to find 
liborg.eclipse.swt.gtk.linux.x86.a and not just 
org.eclipse.swt.gtk.linux.x86, so I've added "lib" to the file 
names and got this:
http://pastebin.com/dVzzXqS6

Any help?

Ok, to avoid that you can I think you add a colon before the library 
name when linking:

-L-l:<lib>

Where <lib> is the library linking. The build script should be changed 
to append prepend "lib" to the library names.

Crap, it seems you need to manually link with the system libraries. 
They're located in this array:

https://github.com/d-widget-toolkit/dwt/blob/master/build.d#L101

Hope that solves it. Sorry for the inconvenience.

Manually linking worked for me, thanks!

One more question: where can I find documentation and some 
examples how to work with DWT? I don't even have an idea how to 
load an image as an icon. There is "Shell.setImage(Image image)" 
method but how can I create an Image-object?

I wanted to run away from Java, but it still haunts me :(

DWT and SWT follow the same API, so just google SWT for
documentation

The official API reference for SWT is here:

http://www.eclipse.org/swt/javadoc.php

There's a bunch of snippets here:

http://www.eclipse.org/swt/snippets/

Some of which are already ported to D:

https://github.com/d-widget-toolkit/org.eclipse.swt.snippets

You should already have these if you're cloned the DWT repository correctly.

If you need any D related help, like threads, IO, delegates or similar 
please continue asking here.

There are a couple of differences/extension in DWT.

http://dsource.org/projects/dwt/wiki/DiffToOriginal

"Package and Module renames" isn't true anymore. I guess I should add 
this list to Github.

OK, thanks for the links!

First noob question:

I need an icon for the window. The Shell class has a method 
setImage(Image image). In Java there is a SWTResourceManager 
available:

shell.setImage(SWTResourceManager.getImage("/home/virtualbox/favicon.png"));

I've looked around a bit in *.di files and found an Image and an 
ImageLoader classes. Maybe it could work but I don't know how to 
create a Java String...

ImageLoader imageLoader = new ImageLoader();
Image image = new Image();
image.init_(imageLoader.load("/home/virtualbox/favicon.png"));
shell.setImage(image);

SWTResourceManager is not part of the standard SWT. It's seems to be a 
part of WindowBuilder. Here's an example of how to set the icon of a window:

http://www.java2s.com/Tutorial/Java/0280__SWT/Setleftuppercornerimage.htm

That site contains many other SWT tutorials as well.

Thanks a lot! One more question: how do I work with events?

Found out how to handle events:

class DisposeListenerImpl:DisposeListener{
    public void widgetDisposed(DisposeEvent e) {
        writeln("Disposed");
    }
}	

shell.addDisposeListener(new DisposeListenerImpl);


Is this the right way?

Yes, that's the standard SWT/Java way. You should be able to use a 
delegate as well. See:

https://github.com/d-widget-toolkit/org.eclipse.swt.gtk.linux.x86/blob/master/src/org/eclipse/swt/widgets/Listener.d#L103

The same exist for Runnable as well:

No, unfortunately the browser package never got ported properly. I think 
it was ported at some time, but only for Linux. It also depends on an 
additional external library. I can always try at compile and see what 
happens.

So if there is no Browser module, how can I display some HTML in 
my app?

I don't know. You can always try and finish the port if you really need 
to display HTML.

You could use whatever API Gtk provides to render HTML. What you would 
use if you weren't using DWT.
