Re: [flexcoders] Event Dispatching through more than one component
It doesn't happen automatically. You need to set this up, but it's not hard to
do. the thing about popups is that they act essentially like their own
application. so they don't normally pass events outside of the popup window.
events originate and terminate with the popup.
so for example, if you have
parent application
|
popup #1
|
popup #2
dispatch the event in popup #2 and listen for it in popup #1.
in popup #2 you would do a dispatchEvent(new Event(myCustomEventPopUp2))
and in popup #1 in the same location that you generate/ create popup#2 you
would put an event listener on popup #2.
ie: popupObj.addEventListener(myCustomEventPopUp2,myPopUp2Function)
then in your function:
function myPopUp2Function(event){
dispatchEvent(event)
}
Then in your parent app, you would put in the same kind of listener as you had
in the first popup:
ie: popupObj.addEventListener(myCustomEventPopUp2,myPopUp2Function)
It's a little round about, but it will get the job done. unfortunately, flex
doesn't handle this sort of event handling.
Hope that helps.

Subject: [flexcoders] Event Dispatching through more than one component
I'm still messing around with custom events.
If I have a popup embedded within another popup and want to dispatch an
event from the top-most component down to the parent application, do I
have to dispatch it to the first popup, and then redispatch the same
event to the parent app?
Is there any way to dispatch an event, but have it automatically go
through all components down to the root? Obviously I've tried, but
events seems to stop at the parent component, and they are not
automatically delivered to their parent's parent, etc.
What I'm thinking of doing instead is having each popup send a message
to the root to open other embedded popups, so that they are ALL created
from the root application rather than the popup. In essence, a custom
popup manager.
But I'm still curious if there's a way around the above scenario.
Thanks,
- Chris

RE: [flexcoders] how do you dispatch event from a custom class?
Hi Paul,
So I'm putting my event listener in the application
core. What I would like is for this event to enter
the event stream and bubble up to the application
core. Currently, it doesn't look like it even makes
it out of the document that I'm in. I'm not even sure
that it gets populated outside of the class itself.
What i'd really like is to have this event entered
automatically into the event stream with out having to
have an event repeater.

Re: [flexcoders] how do you dispatch event from a custom class?
is there anyway to enter an event into the event
stream without a class being a display object? ie,
not having it in the display list?

Hello Paul
In your code you are creating a separate
EventDispatcher, which is not
part of any displaylist. If you let your
WebServiceCheck dispatch the
event instead, it should work. At least as long
as
it is part of a
displaylist.

[flexcoders] is a header renderer supposed to remember it's state?
So I've been messing around with a DataGrid headerRenderer, trying to use a check box to select/unselect a bunch of other check boxes in a data grid. What I'm running into is that if I send out an itemUpdated event or if I update the dataProvider in such a way that it fires off the itemUpdated event (or whatever event it is) it invalidates the header. What I'm running into is that it seems like I can't get the header to remember it's current state if I change it. It always reverts back to the primitive state upon an update event from the dataGrid. If you click on the checkbox in the header, you'll see what I mean. it should check all boxes in the datagrid column and remain clicked, however it doesn't. clicking on the column header will check all of the column boxes, but the column header remains unchecked - even though it is specifically set to checked. Am I doing something wrong here? Anybody know how to get around the problem? Is this not supported? test swiff is located here: a href="" href="http://www.wokits.com/code_samples/checkBoxTest/testHeaderCheckBox.html">http://www.wokits.com/code_samples/checkBoxTest/testHeaderCheckBox.htmlhttp://www.wokits.com/code_samples/checkBoxTest/testHeaderCheckBox.html/a code is located here: a href="" href="http://www.wokits.com/code_samples/checkBoxTest/testHeaderCheckBox.zip">http://www.wokits.com/code_samples/checkBoxTest/testHeaderCheckBox.ziphttp://www.wokits.com/code_samples/checkBoxTest/testHeaderCheckBox.zip/a Appreciate the help.
