All,
Facing an interesting situation...
timerexec(long delay, Runnable r) in Display suggests that the r will be run *after* delay milliseconds.
I tried a quick piece of code:
int i = 0;
while( i <= 10){
mine mn = new mine(i);
Display.getDefault().timerExec(500, mn);
i++;
}
i++;
mine last = new mine(i);
Display.getDefault().timerExec(500, last);
class mine implements Runnable{
int j = 0;
public mine(int i){
j = i;
}
public void run() {
System.out.println( " mine: " + this + " value: " + j);
}
}

This prints out:
value : 12
value : 10
value : 9
value : 8
value : 7
value : 6
value : 5
value : 4
value : 3
value : 2
value : 1
value : 0

Questions:
1. I expected the sysouts to be printed in reverse?
2. In my actual program, I do not have control on a set of events which are timerexec'ed at 500 sequentially. (in some other part of program, cannot change code)
I would like to schedule a timerexec at the end of this set...so that I know
for sure that all previous timerexecs have already been executed!
3. Does display timerexec guarantee order amongst "ready runnables" in its timerList
like ordering them according to time of submission or some other criteria?
Any ideas/suggestions?
