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:
---
import arsd.minigui;
void main() {
auto window = new MainWindow();
auto exitAction = new Action("E&xit");
exitAction.triggered ~= { window.close(); };
window.statusTip = "D ROX!";
auto button = new Checkbox("Uses D!", window);
button.isChecked = true;
auto hlayout = new HorizontalLayout(window);
auto gb = new Fieldset("Type", hlayout);
auto gb2 = new Fieldset("cool", hlayout);
auto boxlol1 = new Radiobox("Test", gb);
auto boxlol2 = new Radiobox("Test2", gb2);
auto boxlol3 = new Radiobox("Test", gb);
auto boxlol4 = new Radiobox("Test2", gb2);
auto group = new MutuallyExclusiveGroup();
group.addMember(new Radiobox("Heavyweight", gb));
auto btn = group.addMember(new Radiobox("Small library",
gb));
btn.isChecked = true;
btn.statusTip = "205 KB exe on Windows";
//auto spinner = new Spinner(window);
ComboboxBase cb = new DropDownSelection(window);
cb.addOption("test");
cb.addOption("cool");
cb.setSelection(1);
//cb.addEventListener("changed", (Event ev) {
//auto bm = new MessageBox("changed " ~
cb.options[cb.selection]);
//});
// FIXME: adding this to gb2 instead of window causes wtf
stuff
cb = new ComboBox(window);
cb.addOption("test");
cb.addOption("cool");
cb.setSelection(1);
cb = new FreeEntrySelection(window);
cb.addOption("test");
cb.addOption("cool");
cb.setSelection(1);
auto lineEdit = new LineEdit(window);
auto menu = new MenuBar();
auto fileMenu = new Menu("&File");
auto exitButton = fileMenu.addItem(new
MenuItem(exitAction));
menu.addItem(fileMenu);
window.loop();
}
---
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...

I believe it's impossible because a parameter tuple is not a runtime entity. If it was an expression tuple (a compile-time tuple of only values, no types or symbols) and all of the values had a common base type, you could put it in an array and index that.

Is there any reason that this module is not complete for platforms other than Linux -- the ioctl() system call is common across all Unix-like OSes, so it doesn't make sense that this is only partially supported. (I am using the latest DMD).

Well, the last error is caused by not import equal in that code (since the
imports that would import it are local imports elsewhere in the module).
As for the main error, you have parens on the declaration of Result.
static struct Result()
I don't know why you put them there, since Result is already effectively
templated by being inside of a templated function, and having it requires
that Result than have !() as a template argument when you're constructing
it. So, I'd say that you should just remove the parens - or if you have a
good reason that I can't think of which makes it make sense to put the
parens on Result, then you'll need to use !() when constructing it.
In any case, having the parens there but not using !() when constructing the
Result is what gives you the error you're seeing. If you remove the parens,
you get something more like
substitution.d(159): Error: template instance hasSlicing!R template
'hasSlicing' is not defined
substitution.d(160): Error: template instance hasLength!R template 'hasLength'
is not defined
substitution.d(176): Error: static assert "Handle R without slicing"
substitution.d(195):instantiated from here: findingSplitter!("a == b",
string, string, string, string)
Adding the appropriate imports results in something along the lines of
substitution.d(177): Error: static assert "Handle R without slicing"
substitution.d(196):instantiated from here: findingSplitter!("a == b",
string, string, string, string)
Beyond that, I'd have to figure out exactly what you're up to, but it looks
like that static assert is probably there to indicate that code needs to be
added as opposed to there being another bug that needs fixing.
In any case, that should at least help you make progress.
