Subject [jira] [Commented] (FLEX-33190) GridEvent.GRID_DOUBLE_CLICK is dispatched even when two different cells are clicked
Date Tue, 25 Sep 2012 00:10:07 GMT

    [ https://issues.apache.org/jira/browse/FLEX-33190?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13462282#comment-13462282

Joshua White commented on FLEX-33190:

I would like to suggest this is not a bug. When you click between two cells very quickly you
are double clicking on the grid. The event being dispatched represents this correctly and
I have had cases where I would want it to dispatch this event. This update would break functionality
of at least one project I have worked on in the past.

I've had the same thought in the past and have had to do a lot of confirmation of the double
click event (was something selected, was that thing clicked on both times, etc) and I agree
something needs to change, but this is definitely a feature and will change existing expected
behaviors. From the AS3 grid documents: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/spark/components/Grid.html

"doubleClickEnabled : Boolean
[override] Specifies whether the UIComponent object receives doubleClick events."

I suggest closing this issue and requesting a feature where the grid dispatches a CELL_DOUBLE_CLICK
which can be enabled with a new property on s:Grid or perhaps that there is a new property
which indicates doubleClickMode = "WHOLE_GRID||SINGLE_CELL||ROW||COLUMN"

But there is no check of whether the same cell was clicked.
