Hi All,
Is there some kind of onIdle event available in qooxdoo 0.8? We are
working on quite a large application and mainly coming from a C++
background. With Borland's VCL there was an onIdle event that you could
hook into and was ideal for enabling/disabling controls depending on an
application's state.
If not, this is the best solution we could come up with after looking at
the source code:
* Create a class that implements qx.event.IDispatcher (more than likely
this would also be a singleton)
* Register this in qx.event.Registration.addDispatcher with a high priority
* qx.event.Manager will call our canDispatchEvent method for every
(correct?) event fired
* For all events that can change the 'state' of our application, e.g.
click and and key press we do something along the lines of the following
but always return false
killTimeout(this.timer);
this.timer = setTimeout(... , 0);
* Once all events have been handled our last time-out will fire once,
when the browser becomes 'idle'
* The timeout then dispatches an 'idle' event to all widgets that are
interested.
That's the plan. The idea is then we can add an event listener for this
'idle' function whenever we need it. The code inside these handlers will
be quick, simple things such as enabling a control as long as checkbox
is ticked.
What are peoples thoughts on this?
Many Thanks In Advance,
Matthew
