Jason, this was an eye-opener!
Till now I didn't realize that an event listener can cancel another
listeners. But the preventDefault() method of the Event class does
exactly that.
This is the way I should go with a PagableGrid.
Thanks!

Actually, preventDefault() does NOT prevent other listeners from executing;
this is what stopPropagation() and stopImmediatePropagation() do.
preventDefault() simply sets the flag returned by isDefaultPrevented() to be
true. However, some event-dispatching code in the Player or the framework
Private methods and variables drive me nuts..
For example, I'd like to make a simple DataGrid change: make headers
clickable without refreshing the grid (just toggle a sort icon).
(I need this behaviour because I'd like to have a paging DataGrid
which only propagates the sort column/direction

When I did Java, I always made my private variables 'protected', but the real
Java guys tole me that was a bad idea for some reason.

Perhaps in some cases are, but in the example above - there's no
need for it. As you have seen, I'm trying to override an user
gesture (header click) and I can't neutralize the default
behaviour, which is a grid refresh.
Flex 2.0.1 is so carved in stone.. I'm waiting to see the next
version..
Danko,
See below extended datagrid and sample application to do what you want. I
realize its frustrating when you need to do things only to find yourself
blocked in the obvious way; but there is definitely more then one way to
skin a cat (so to speak).
Im sure future versions of the flex
As a follow up to the last response, take note of the
event.preventDefault(); in the handler for HEADER_RELEASE, and the fact that
I don't do a refresh on the ListCollectionView after adding the
sort to it.

Great!! It works...
I noticed a slight delay when loading a real data into the grid (6
cols x 20 rows). Does grid do some processesing? Or this method
stops all other method execution?
Now, if the similar solution for manipulating the scroller is
available.. it would be great. :-)
Anyway,

So you extend the parent, and cut and paste most of the code.

I am currently working on a project where we have had to extend many
of the framework controls and containers to add extra functionality or
fix little things that were bothersome. While it has been an very
difficult task in places is has not been impossible. I certainly would
not advocate the 'cut

I have extended quite some components aswell. What i found out however, was
that in the en i most of the time did not need those private variables and
methods. At the end of a day full of fiddling i found a

If you want to say that we shouldn't rely on needing access to any private
variables, it's only a small difference to say it's OK to rely on
mx_internal variables. The internal vars are marked as such because they
might change in future releases. So if the objection is that your code might

Maybe because there seems to be more of a drift toward composition
instead of inheritance?

I agree that it can be difficult to modify functionality in the
framework classes. I think that much can be done to enhance this
process, and perhaps we can help Adobe out with ideas. I have found
that many things can be modified by thinking differently. Some of the
design patterns that the Flex
16 matches
