Does anyone know how to get the Object
source of an Event, in Dig. ie:
Button b;
//later on
with(b = new Button("1")){
onClick(handleEvent());
}
// later on
handleEvent(Event event){
//now how do I get the Object source and
// string from the button from the parameter
}
I have made a simple calculator with 18 buttons,
at the moment I have a function to handle each buttons
event ie: 18 Event functions.
Code attached.

I'm afraid that while that was always in the plan, I never got around to it. However, it's easy to do what you want in this case. Just have something like this: class AppendFunction { char [] text; /**< Text to append. */ this (char [] text) { this.text = text; } void event (Event event) { ed.text (append (ed.text (), text)); } } void doView () { int c, r = 1; void createNumericButton (char [] text) { with (new Button (this)) { caption (" &" ~ text ~ " "); grid (c ++, r, 1, 1); sticky ("<>^v"); bordered (true); onClick.add (&(new AppendFunction (text)).event); } } void nextRow () { c = 0, r ++; } createNumericButton ("1"); createNumericButton ("2"); createNumericButton ("3"); nextRow (); createNumericButton ("5"); createNumericButton ("6"); createNumericButton ("7"); nextRow (); createNumericButton ("8"); createNumericButton ("9"); createNumericButton ("0"); nextRow (); ... }

Thanks Burton! That works great, it will also be a great help in the future. Phill.
