Timer event in a PUI program.

[nascar88]

I would like to return to my rpgle pgm every xx minutes to see if a control record has been changed and if so, reload a subfile based on the changed record.

I am not a java programmer, but after searching the web I found the following code but can't figure out if / how to make it work in the onLoad event.

If anyone is doing this --- I would appreciate your help.

----------------------------------------------------------------
import java.util.Timer;
import java.util.TimerTask;

public class Main {
public static void main(String[] argv) throws Exception {
int delay = 5000; // delay for 5 sec.
int period = 1000; // repeat every sec.
Timer timer = new Timer();

timer.scheduleAtFixedRate(new TimerTask() {
public void run() {
System.out.println("doing");
}
}, delay, period);
}
}

What you want is JavaScript, rather than Java. Although the name is similar, they are entirely different programming languages.

You cannot call Java code directly using browser events -- these are handled by JavaScript.

Basically, you could accomplish what you want with:

1. Using JavaScript's setTimeout() method to run a JavaScript function after X number of seconds.

2. The JavaScript function that runs on the timer can call Profound UI's "pui.click()" JavaScript API to submit the page to the server. This function accepts an optional button id, so you can simulate a click on a (probably hidden) button with response indicator bound. This way your RPG code would know that the screen is submitting for this vs. another reason.

But, it might not be quite so simple. To make this user friendly, you'd probably want to reset the timer if the user takes some action on the screen so that it's not "leaving without them".

You could do that by storing the return value from setTimeout() and then clearing/resetting it if the user has moved the mouse or keyboard.
