Subject [jira] [Commented] (FLEX-33883) Spark Datagrid - double click event is executed incorrectly
Date Thu, 07 Nov 2013 11:17:19 GMT

    [ https://issues.apache.org/jira/browse/FLEX-33883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13815852#comment-13815852

Gareth Daniel Smith commented on FLEX-33883:
--------------------------------------------

I have come across this before and also found it surprising/error-prone.

That said, however, I am not convinced that the event should only be triggered when double
clicking on a row. The doubleClick event is not a DataGrid specific event, and giving it special
behavior for DataGrids might be surprising. IMHO it might make more sense for a new itemDoubleClick
event type to be introduced, perhaps using the DataGridEvent class (e.g. like the ExtJS Grid:
http://docs.sencha.com/extjs/4.0.7/#!/api/Ext.panel.Table-event-itemdblclick).

Interestingly, the MX DataGrid doesn't fire a double click event on the scrollbar, but *does*
on the column headers.

> When I select a row, and then make a double click on the scrollbar a double click event
is triggered.
> I think that the event should only be triggered when you double click directly on the
row.
