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?

Now all is as it should be except for the {missing or misplaced '}'}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.1/ Can anybody see why I get this message? Also "System.currentTimeMillis()"is a C style request .Looks more Java-style to me...2/ is there a similar request in D for a Linux machine?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. ;-) --bb

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.

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?
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;
