Sort of. I still haven't used it in a real world program so it 
isn't complete but here's one of my test programs:

[...]



On Windows, it uses the native controls, so it should work 
reasonably well, though on Linux it does its own thing and is 
far from complete.




BTW simplewindow doesn't seem to compile on newest dmd because 
of the new core.sys.windows.windows so I'll have to update that 
if you're on the newest release...


Thanks Adam,
I have DMD 2.068.2 so far so it did work.
However it seems to be not so accessible as I expected (tested 
with JAWS for Windows, latest release [1]). For instance, the 
focus lands nowhere when the program is launched. Then there is a 
(not too comfortable) possibility to make it show the elements to 
the screen reader upon pressing Tab.

Adam D. Ruppe's Minigui using example

[Andre Polykanine via Digitalmars-d-learn]

Hi everyone,
I would like to use Minigui 
(https://github.com/adamdruppe/arsd/blob/master/minigui.d) and 
test it for accessibility.
Does anyone have an actual example of, say, a simple form with a 
set of radio buttons or check boxes to start with?

Thanks in advance!

Yes, DFL!
https://github.com/Rayerd/dfl
It's a thin wrapper over WinAPI so all controls are native. I've 
built several apps with it and quite happy with this library. It 
comes with a graphical interface builder called Entice Designer 
which is rather old but still works fine. Also, with this lib 
your app is just a single binary less than 1 MB, no additional 
DLLs required.

Working Windows GUI library?

[Andre Polykanine via Digitalmars-d-learn]

Hi everyone,
Does   anyone   of   you  work  with a Windows GUI library with native
controls in order to write desktop apps in D?
Here  is  why  I'm  asking:  actually, there are quite a number of GUI
libraries listed at wiki.dlang.org.
However, I have one specific requirement: the resulting apps should be
accessible  for blind and visually impaired users. To do that, Windows
native  controls are highly preferred since they are treated correctly
by  screen  reading  software.  So  no  QT,  no GTK (they are both not
accessible under Windows).
I've  tried  to  build  samples for each library, and got virtually no
results:  DGui was the only one that caused no problems at all, but it
has   almost   no   documentation   and   most   of  the  samples  are
drawing-related.
So  my  question  is:  is  there any reliable GUI library implementing
native Windows controls?
Thanks!

Hello Adam,

ADRvDdl> Easily usable by the blind or people with motor difficulties and

Exactly, thank you.
I.e.,   the   app   should   be usable without mouse and with a screen
reader (to over-simplify the
things).

Templates and writing variable number of arguments

[Andre Polykanine via Digitalmars-d-learn]

Hi everyone,
It's me again.
Now  I'm  struggling  with  the  `output` member function which should
output  a  string  either  to  stdout  or  to a file, depending on the
parameter.
However,  I would like it to work like `writefln` with variable number
of arguments:
output(Hello %s!, world); // should be OK
output(%s  %s:  %s  %d  times,  I, say, Hello world!, 500); //
Should also be OK

Here is my code:

final void output(T)(string text, T params...) const {
if (this.outFile == ) {
writefln(text, params);
} else { // Output to a file
auto f = File(this.outFile, w);
try {
f.writefln(text, params);
} catch(Exception e) {
writefln(Unable to write to %s: %s, 
this.outFile, e.msg);
}
}
}

And the compiler says it can't deduce the type of arguments.
What am I doing wrong here?
Maybe, I don't need such a function and all and there is a way to make
it more elegant?
Thanks!

Re: A couple questions about a simple project

[Andre Polykanine via Digitalmars-d-learn]

Hello John,

Yes, but this doesn't work, either.
Now I have this (that was my first variant, btw):

string s;
try {
s = cast(string)std.file.read(f);
try {
check(s);
if (this.verbose) {
output(format(%s: 
validation passed!, f));
}
} catch(CheckException e) {
// This is output when a file is invalid, that works
output(format(Failed to 
validate %s: %s, f, e.toString()));
}
} catch(Exception exc) {
//  And  that  isn't  output,  I  see  just  the  stacktrace as if the
exception was not caught at all
output(format(Error reading %s: %s, 
f, exc.msg));
}
}

To  catch  the  exception,  I  need  to  wrap  the  validate() call in
`try...catch` in `main()`. Why so?
Thanks!

Check if args has changed length after calling getopt, if not

 tried both `try...catch` and `enforce` (current version:

D Wiki: Windows programming examples are missing

Hi everyone,
I'm fairly new to D and am really excited about it.
I would like to see more examples of Windows programming in D, but the
repository indicated on the D wiki seems to be moved or deleted.
More info is here:

Thanks!
