Ok I managed to find a workaround and got it working. What I did was
monkeypatch spark.components.gridClasses/GridColumnHeaderView and then
changed the code to
public static var dpiScaleFactor:Number = 1;
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*dpiScaleFactor))) &&
(eventStageY < (origin.y + height));
}
and in my application on preinitialize I do
GridColumnHeaderView.dpiScaleFactor = (runtimeDPI/applicationDPI);
This is working fine for me on the device now and fixes the issue, but I'm
sure someone with a deeper knowledge of the SDK can take a look for a
better fix?
