[flexcoders] Re: Detecting a click on an empty part of AdvancedDataGrid

Try using the mouseFocusChange event.  I've used it a few times for
deselecting items in a list when anywhere else is clicked.  For your
needs, you may have to adapt it but give it a try.

I have a blog post about it at:

 I tried using grid.getObjectsUnderPoint() in the click event, but
the
 results aren't very useful. I guess I could depend on the fact that
 there are always more than three objects when I click on a real row,
 and exactly three when I click on empty space, but that seems like a
 bad thing to depend on. Who knows what future versions of Flex will
add
 to the list?

 There must be a better way!

 Thanks.

Thanks. That's very close to what I want. However, this method 
disables multiple-select. It deselects items when you click 
_anywhere_. I only want to deselect when you click on empty space.

Also, when I change focus to another window and then back to the flex 
app, mouseFocusChange stops firing. It never fires again after that.

[flexcoders] Re: Detecting a click on an empty part of AdvancedDataGrid - SOLUTION

[whatabrain]

I found the solution to my problem. It depends on the fact 
that click is fired after itemClick.


var m_processingItemClick:Boolean = false;

private function onItemClick(event:ListEvent):void
{
processingItemClick = true;
}

private function onClick(event:MouseEvent):void
{
if (m_processingItemClick)
m_processingItemClick = false;
else
grid.selectedIndex = -1;
}
