Mark Kessler updated FLEX-33190:
--------------------------------
Attachment: Grid.as
Here is a possible fix for it. Added a new variable to track the last row
clicked and does a check for it in the doubleclick. This should also correct
lack of single click events being triggered. Was unable to recompile the SDK
with ant to test properly.
private var lastClickRowIndex:int = -1;
private function dispatchGridClickEvents(mouseEvent:MouseEvent,
gridXY:Point, rowIndex:int, columnIndex:int):void
{
var dispatchGridClick:Boolean = (rowIndex == mouseDownRowIndex &&
columnIndex == mouseDownColumnIndex);
var newClickTime:Number = getTimer();
// In the case that we dispatched a click last time, check if we
// should dispatch a double click this time.
// This isn't stricly adequate, since the mouse might have been on a
different cell for
// the first click. It's not clear that the extra checking would be
worthwhile.
if (doubleClickEnabled && dispatchGridClick && !isNaN(lastClickTime) &&
(newClickTime - lastClickTime <= DOUBLE_CLICK_TIME) && rowIndex ==
lastClickRowIndex)
{
dispatchGridEvent(mouseEvent, GridEvent.GRID_DOUBLE_CLICK, gridXY,
rowIndex, columnIndex);
lastClickTime = NaN;
lastClickRowIndex = -1;
return;
}
// Otherwise, just dispatch the click event.
if (dispatchGridClick)
{
dispatchGridEvent(mouseEvent, GridEvent.GRID_CLICK, gridXY,
rowIndex, columnIndex);
lastClickTime = newClickTime;
lastClickRowIndex = rowIndex;
}
}
> GridEvent.GRID_DOUBLE_CLICK is dispatched even when two different cells are
> clicked
