Could somebody briefly outline the different GUI toolkits

For instance: DlangUI and Adams D Ruppe's `simpledisplay`

I'm the author of Tkd[1] and wrote it to learn D in more depth
and really enjoyed the flexibility of generic
classes/functions/interfaces and mixins. Because Tkd is based on
Tcl/Tk it was really hard to map the Tcl language and Tk toolkit
to a sensible type hierarchy using inheritance. Using D gave me
the opportunity to think a bit differently and compose types more
simply while modeling the problem in a more intelligent way. I'm
bias, but I love the simplicity of the finished code.
A pattern I used throughout was this:
class Foo : Bar
{
public auto baz(this T)(...)
{
...
return cast(T) this;
}
}
Which allows chaining of methods with those of parent and child
types, i.e:
import tkd.tkdapplication;
class Application : TkdApplication
{
private void exitCommand(CommandArgs args)
{
this.exit();
}
override protected void initInterface()
{
auto frame = new Frame(2, ReliefStyle.groove)
.pack(10);
auto label = new Label(frame, "Hello World!")
.pack(10);
auto exitButton = new Button(frame, "Exit")
.setCommand(&this.exitCommand)
.pack(10);
}
}
void main(string[] args)
{
auto app = new Application();
app.run();
}
