events coming back to source

[Tomba]

Hi,

I have here a panel on which 3 controls are displayed. All of them show
some information of the same data object "Data". Every of the three
controls listens to changes in the Data object.

Now however, when the user clicks something in eg. control2, that
control for instance performs data.update(). Data then fires events,
which is ok except for control2 who doesn't need to be notified of
course as control2 itself was the cause of the event.

Now my question: how can I prevent control2 from acting on the event?
(in my example it may also be control1 or control3 of course).

Thanks a lot,
happy holidays

Declare a boolean flag in control2. Set it to false. When you're
firing an event, set it to true just around the call that fires the
event, then set it false again right after. In the event handler, check
the flag, and return immediately when it's true.
