---------------------------------
Labels: easyfix newbie (was: newbie)
> spark DataGrid causes a tooltip (text: "<dataTip>") to appear for its typical
> item renderer although mouse not over data grid
> -----------------------------------------------------------------------------------------------------------------------------
>
> Key: FLEX-33604
> URL: https://issues.apache.org/jira/browse/FLEX-33604
> Project: Apache Flex
> Issue Type: Bug
> Components: Cell Renderers, Spark: DataGrid, Tooltip Manager
> Affects Versions: Apache Flex 4.9.0
> Environment: Tested on a Win 8 and a Win 7 system.
> Reporter: Mihai Chira
> Priority: Critical
> Labels: easyfix, newbie
> Attachments: FaultyTooltipViaDataGrid.fxp
>
>
> Run the application below (or import the attached project into FlashBuilder)
> and click the second tab.
> Actual result: a tooltip appears next to the mouse saying "<dataTip>".
> Desired result: no such tooltip should appear.
> Notes: from what I could tell, it happens because the data grid creates its
> typical item renderer during a measure() call; the renderer, through the
> validateNow() function, registers itself with the TooltipManager; in that
> function ("registerToolTip()"), the latter checks if the mouse is currently
> over the target. In reality it's not, but because all this happens during
> measure, the parents of the renderer haven't been measured yet, so its
> localToGlobal() function returns wrong data. This happens to indicate that
> the current mouse position is over the renderer. Therefore the tooltip is
> shown.
