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.

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;

Thanks but this did not work .Did I mess it up?

Oh and output seems to be generated by the selection itself The output from the above is

C3dwt7widgets5Event5Eventevent

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

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?
