Knowing if my app is being used [message #459028]

Thu, 28 July 2005 17:06

I have an app which needs to automatically log a user out after a period
of inactivity. The timer stuff is easy enough. The problem is how do I
know the user is actively using my app? I am hoping to not have to hook
into every widget to know they typed in it, or selected it, or clicked
it, etc.

Any ideas?

Thanks,
Mike Higginbotham

You could add an event filter to the display (Display.addFilter()) to
listen for all MouseDown and KeyPressed events that occur in your
application.

Well, presumably the widgets all hook into listeners, which call your
apps code - why not trigger off YOUR code?

Yes, but beware of timing users out during long-running operations. They
won't be happy, especially if the "log out" triggers strange failure
modes in the operations.

Thanks, Stefan! This is what I was looking for. I tried addListener but
for some reason totally missed addFilter. Perfect.

The problem is that there are a number of classes/views which I have to
monitor. I could do as you suggest but any new views would have to
remember to "play nice". By using addFilter, I can keep all the timeout
code in one place and new views do not have to worry about it.

Luckily, I do not have any long running operations. The timeout is 15
minutes of inactivity and is reset whenever they click the mouse
(SWT.MouseUp) or press a key (SWT.KeyUp) in the application.

Look at:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=37061

It has a code snippet for exactly what you need.
