I have a Listener added to a button as so :-
button.addListener(DWT.Selection, new class Listener {
void handleEvent(Event event) {
itemWords [5] = "item has changed " ;//~ System.currentTimeMillis();
minitable.clear(5); } });
When pressed the button outputs this:-
Event {missing or misplaced '}'}Event {type=13 Button {Change item}
time=1679601378 data={null} x=0 y=0 width=0 height=0 detail=0}
.
Now all is as it should be except for the {missing or misplaced '}'}
1/ Can anybody see why I get this message?
Also "System.currentTimeMillis()"is a C style request .
2/ is there a similar request in D for a Linux machine?

That's a Tango thing. Functions like formatln must have all '{' chars
escaped in the format string. So you or DWT are using a tango string
formatter somewhere you or DWT should probably not be. It should be
print() instead. Yet another reason I don't love Tango for output.

Looks more Java-style to me...

probably something in tango.time.Time.
How about this: tango.time.Time.Clock.now.time?
And if that doesn't work stick a few extra .time's .clock's or .now's on
the end and see if it does. ;-)

Tango's formatting uses a pair of curly braces like "{}". Your output is
supposed to go "{Event {type=13....", but Tango sees the opening '{', tries
to parse it as a format specifier, and fails, leaving you with an error
message embedded in the output.
The question I have is: where is this output being generated? This code
doesn't seem to generate it.
I ask because it's a simple fix: instead of doing something like
"Stdout.formatln(x.toString())", just use "Stdout.formatln("{}", x)", that
is, escape the string by making it a parameter to be formatted.

The problem is in dwt's dwt/widgets/Event.d, toString method:
override public char[] toString () {
return Format( "Event {type={} {} time={} data={} x={} y={}
width={} height={} detail={}}",
type, widget, time, data, x, y, width, height, detail );
//$NON-NLS-1$//$NON-NLS-2$ //$NON-NLS-3$ //$NON-NLS-4$ //$NON-NLS-5$
//$NON-NLS-6$ //$NON-NLS-7$
}
It needs to escape the first and last '{'s.
Can you fix it, Frank?

The output from the above is

PS5tango4time9WallClock9WallClockclock
[ item 0 , item 1 , item 2 , item 3 , item 4 , item has changed clock ,
item 6 , item 7 , item 8 , item 9 ]
Event {missing or misplaced '}'}Event {type=36 Table {} time=1752657025
data={null} x=0 y=0 width=0 height=0 detail=0}
(note there is no output for event.stringof or for clock.stringof -a blank line
So I'l try formating the event and see

Ended up using Tango book solution for current date display -Time too complex
import tango.time.WallClock;
import tango.text.locale.Locale;
auto layout = new Locale;
Stdout.print(layout ("{:ddd, dd MMMM yyyy HH':'mm':'ss z}",
WallClock.now)).newline;
