-----------------------------------
Summary: DataGrid MouseOver issue when scaled
Key: FLEX-35047
URL: https://issues.apache.org/jira/browse/FLEX-35047
Project: Apache Flex
Issue Type: Bug
Components: Advanced Data Grid, Spark: DataGrid
Affects Versions: Apache Flex 4.14.1
Reporter: Jan F. Weber
Setting scaleX and/or scaleY on a spark DataGrid does not handle mouse over
events correctly.
This is issue is related to the functions "containsMouseEvent" located in class
GridView.as and GridColumnHeaderView.as.
These functions do state:
/**
* True if this GridColumnHeaderView's bounds contain the event.
*
* Currently this method does not account for the possibility that this
GridColumnHeaderView has been
* rotated or scaled.
*/
/**
* True if this GridView's bounds contain the event.
*
* Currently this method does not account for the possibility that this
GridView has been
* rotated or scaled.
*/
A possible fix (as suggested by user "y-tanaka") would be the following
modification to these functions:
public function containsMouseEvent(event:MouseEvent):Boolean
{
const eventStageX:Number = event.stageX;
const eventStageY:Number = event.stageY;
const origin:Point = localToGlobal(zeroPoint);
// origin.x += horizontalScrollPosition;
// if (layoutDirection == LayoutDirection.RTL)
// origin.x -= width;
//
// origin.y += verticalScrollPosition;
//
// return (eventStageX >= origin.x) && (eventStageY >= origin.y) &&
// (eventStageX < (origin.x + width)) && (eventStageY <
(origin.y + height));
return hitTestPoint(eventStageX, eventStageY, true);
}
