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.
Phill.

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 ();
...
}
