[flexcoders] Stopping double-click of a button 'bubble' to the datagrid row

2009-09-01 Thread Nick Middleweek 
Hello,

I've got an advancedDataGrid (AvDG) and the first column has an item
renderer which has a button on it. The button has a click handler.

There is also a itemDoubleClick handler on the AvDG.

Users are double-clicking the button so this is firing the click of the
button handler but the doubleClick event is also being fired on the AvDG row
item.

I'm guessing this is related to event bubbling or capturing?

I'm trying to stop the AvDG.row doubleClick event being fired if the user
double clicks on the button.

Anyone got any ideas? I've tried to put a doubleClick on the button in hope
that it would handle it and therefore stop the row event from being fired
but ti didn't work.


Now I think i need to capture the doubleClick cancel event in the button
object and prevent it from bubbling from the button to the AvDG. Where do I
set event.cancelable = true?


Thanks,
Nick

MouseEvents are not cancelable.  You can kill them via stopImmediatePropagation.

Event.stopPropagation() or stopImmediatePropagation() (depending on whether
you want events on the current node to be executed before the event stops or
not:

?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;

{foo: button 1},

];

private function dg_doubleClickHandler(event:Event):void

}
