[flexcoders] How to remove labels from a chart with ActionScript
Hello,
i'm trying to remove the labels from the horizontal axis of a column chart
(and a line chart) when clicking on a button (and also add it if removed).
For this, i have to use ActionScript, but i'm unable to find the correct
syntax and Object.
Can anyone help me?
I've tried myBarChart.styleName = noAxisStyle; (with a noAxisStyle class
defined with .noAxisStyle
{
showLabels: false;
}
but it doesn't work.
I also tried myBarChart.setStyle(showLabels, true); but it diesn't work.
Finally I tried
AxisRenderer(myBarChart.horizontalAxisRenderers).setStyle(showLabels,
false); but it doesn't work.
No other idea.
Thanks!

[flexcoders] Status Bar on firefox
Hi, I'm working on a flex web app where I connect to a blazeDS server to get some data. I notice that even when I finished loading the data through 1 of my datagrids, I see that the Firefox Status Bar still displays Transferring data from.. url instead of Done. I researched that I could have a way around this but it involves Javascript and the window.status=string hack. But another problem arises: Firefox does not permit changing the status of the browser on default. Btw, the hack works fine on IE. Is there any other way to send parameters to the status bar? Thanks and more power to Flex designers and programmers :D
[flexcoders] How to test flash apps in the normal (non-debug) player with the debug player in installed?
Hi All, I have the flash debug player installed for FireFox and IE. What is the best way to test flash apps in the normal (non-debug) player on the *same machine*? (I don't have access to a spare machine right now). I want to do this test because I have read that the error thrown by ExternalInterface.call is different in the normal player than the debug player, but that was written many months ago, so I don't know if it is still true (e.g. in version 10.x) thanks tom
[flexcoders] Multiple selection in dataGrid by dragging Mouse with left mouse key
Is it possible to select multiple rows in data grid by just dragging mouse over It. I know this can we achieved with combination of sift key and mouse. This need has arisen because we are migrating .DOT Net data grid with flex data grid and user want to have same ease of multiple selection. Initially I was confused with dragMultipleSelection propery of datagird but later I realized that it is for dragging rows and not for selection. Please let me know whether it is possible in flex or not and if it is possible then please provide me some pointers.

[flexcoders] Flex 3 Dialog Boxes ...
Hello All, I'm using Flex 3 and working on pure actionscript projects (i.e: File New ActionScript Project). I often have issues with numerous dialog boxes and parts of the interface within Flex (see images below): http://img339.imageshack.us/img339/512/60793305bx2.gif http://img224.imageshack.us/img224/7996/64384807bn2.gif Tabs and controls within these boxes don't appear correctly. This is not a memory issue as my laptop is a high spec machine and Flex is the only thing running. Also, a recent suggestion made was to update my display drivers, which I have done - unfortunately this hasn't fixed the issue. Anyone advise or have the same problem? Cheers, SF.

[flexcoders] Data Grid with dynamic columns ignoring % width or right style.
Hi All, I've a problem with the DataGrid ignoring the % width, while using Canvas as the parent. When I dynamically create columns it stretches to beyond the origional area. This behaviour has been reported as a bug. http://bugs.adobe.com/jira/browse/SDK-14390. The workarround described in the bug setting the width to 0 works for me in a simple test case but doesn't appear to work within my main application. I've got a test case that I would have to post at work (monday) if its usefull to see the problem. What I was wondering is why setting the width of the grid to 0 worked. I tried raising all the event and invalidateProperties, invalidateSize etc that setting the width property seems to do. But that doesn't seem to work. I would like to extend datagrid with a version that doesn't have this issue if I can figure out why a fixed width doesn't work. Thanks for your time. Wesley
[flexcoders] E4X with RegExp
I'm having trouble parsing some XML.
This works
var
xL0:XMLList=inputXML..node.(/^Gear[0-9]{2}W$/.(test(@name)));
This is apparently should work with a compiler warning
public static const GEARDEF1:RegExp=new RegExp(/^Gear[0-9]{2}$/,i);
var xL2:XMLList=inputXML..node.(GEARDEF1.test(@name));
and using square bracketing like this should work and stop the warnings.
public static const GEARDEF1:RegExp=new RegExp(/^Gear[0-9]{2}$/,i);
var xL2:XMLList=inputXML..node.(GEARDEF1[test](@name));
Trouble is neither of the two methods using RegExp work - which if it
were that simple wouldn't matter. The reason for this is that I need
to build arrays of RegExs to loop over like this.
public static const GEARDEF1:RegExp=new RegExp(/^Gear[0-9]{2}$/,i);
public static const GEARDEF2:RegExp=new RegExp(/^Gear[0-9]{2}W$/);
public static const GEARDEF3:RegExp=new RegExp(/^Gear[0-9]{2}01Loc$/);
public static var geardefs:Array =[GEARDEF1, GEARDEF2, GEARDEF3];
Any suggestions as to why this doesn't work?

[flexcoders] Super class as RemoteClass: Type Coercion failed
Hi, all
I'm a newbie in Flex. Could you help me to understand what's going wrong here?
My Flex sample app uses RemoteObject to call a method of Java class.
This method returns an instance of some ClassA that extends some
ClassB.
public class MyRemoteJavaClass {
public ClassB myRemoteMethod() {
ClassA result = someMethodThatReturnsClassA();
return result;
}
}
When I try to use ActionScript class that maps directly to ClassB:
// ClassB.as
[RemoteClass(alias=com.example.ClassB)]
public class ClassB {
...
}
I get the TypeError: Error #1034: Type Coercion failed: cannot convert
mx.utils::objectpr...@1184fc59 to com.example.ClassB.
With [RemoteClass(alias=com.example.ClassA)] it works fine.
Is it possible to use super class in my example? Thanks in advance.

[flexcoders] Re: Using dispatchEvent ?
Actually, I did think about that and tried changing from EventDispatcher to extending UIComponent but it still does not work. I even tried Canvas and it still does not catch it. As an experiment, though, I tried dispatching the same event from one of my components elsewhere in the application just to make sure the custom event itself was OK, and that worked. Does it make a difference that I am dispatching this event from inside an HTTPService callback? Basically, the way this class works is that I instantiate it with a timer value, and every x seconds it makes a call to the server to get some data, and based on the result of that data I dispatch an event with the payload. --- In flexcoders@yahoogroups.com, Josh McDonald dzn...@... wrote: Event bubbling only occurs within the display list.

Re: [flexcoders] Re: Using dispatchEvent ?
The event listener attached to the Application is not reacting to the event fired from your custom class because your custom class instance is not attached to the Application DisplayList. It is just an object in memory. If you want the event from your custom class instance to bubble up to the Application, you need to add it to the Application's DisplayList. The DisplayList is typically used for UI components, i.e. when you click a button in the UI, it fires an event and that event propagates up the display list. However, you can add non-UI components to it too. Your custom class just needs to extend the DisplayObject class (I think - it should have extended EventDispatcher already). You also need to add the instance to the Application object by using the addChild method on the Application object, e.g. application.addChild(myclass); If you declare the custom class instance in MXML, it is automatically added to the Application object (well, technically, only if it is a loaded component in the UI). 2009/1/12 biosmonkey biosmon...@yahoo.com: The dispatched event needs to be heard by any component, anywhere, by setting an event listener for it at the application level.

[flexcoders] Browser and embeded Flex scrolling together
Currently I'm working on a Flex app for a client that has a VBox with a vertical scrollbar on it. Inside of the VBox is a long list of custom components (based on HBox) that can be viewed by scrolling up and down on the scrollbar. The issue is this application is embeded within a HTML page that has a lot of content below the application, therefore when the user scrolls the mousewheel on my VBox, it scrolls the main page as well. I've noticed that most components do this as well, with the exception being TextArea. I've dug around the livedocs and some forums in hope of finding a solution to make this work, but so far nothing. I was wondering if perhaps anyone has come across this issue and know a solution or a workaround, or have suggestions on how I could better accomplish what I need to do here?

The reason you are having a problem is because of the first in wins rule that applies to loading classes. Your monkey patched VideoPlayer class is in your swf file, but in frame 2. The framework swz file is loaded in frame 1, so its definition of VideoPlayer wins. The way to work around this is to create your own RSL with just your VideoPlayer class and its dependencies.

Well, actually, you can just set moveEffect on the individual children.

Event bubbling is typically for UI events; your event is not a UI event, it's just that you need it to be broadcast application-wide. So I would consider making the event dispatcher object available application-wide, by making it a singleton, for instance, or by making it a property of the main application.

were that simple wouldn't matter. The reason for this is that I need
to build arrays of RegExs to loop over like this.
public static const GEARDEF1:RegExp=new RegExp(/^Gear[0-9]{2}$/,i);
public static const GEARDEF2:RegExp=new RegExp(/^Gear[0-9]{2}W$/);
public static const GEARDEF3:RegExp=new RegExp(/^Gear[0-9]{2}01Loc$/);
public static var geardefs:Array =[GEARDEF1, GEARDEF2, GEARDEF3];
Any suggestions as to why this doesn't work?

Re: [flexcoders] Re: Cairngorm and ChangeWatcher
I don't know if that is indeed the best practice but for now if it suit your needs just do it. The main idea is that the model drives the view, and at the same time it represent the current state of the up. Having a view bound to that model makes the view display the current state for the app. Now you either do it by bindings or by your own implementation of the observer pattern it is up to you. That implementation of the observer in there helps you prevent silent failures, otherwise flex bindings should do just fine. I'm not sure this is what you expected to hear, and I am sorry if I cannot be more helpful. We had an app once an we used a custom error class to handle all the messages/erros in the up (something like model.error.doError()) which handled both the messages and their displaying triggering.

No, child2 adds a listener to its parent - the Container. Child1
dispatches the event, the event bubbles up, Container handles it,

Subject: [flexcoders] Release a child again
Still cannot get it work.
Here is my scenario:
1. Container adds child1 to itself.
2. Container adds child2 to itself.
Child2 adds a custom event listener to parent (Container):
parent.addEventListener(remoteDateEvent,
remoteClickHandler,
false, 0, true);
3. Child1 dispatches a custom event:
private function executeRun(event:KeyboardEvent):void
{
if(event.charCode == 13)
{
var eventObj:remoteDateRun = new remoteDateRun
(remoteDateEvent);
dispatchEvent(eventObj);
}
}
4. Child2 handles custom event:
public function remoteClickHandler(event:remoteDateRun):void
{
runDate = event.runDate;
dailyJobSumaryList(lineId);
}
At this point everything works.
Now, after some user action both forms are removed form the
Container
and all previous steps are repeated.
At this point everything still works.
Now user is going back to his initial selection. Both forms
are
removed again and 3rd set of forms is added to the Container.
At
this
point if a child1 dispatches a custom event then child2 form
set
#1
will get it to handle. Can someone please just put step by
step
instruction how to make sure that a form is released and
collected?
I have spent days if not more trying to fix the problem.
Be better if you can make a complete example. You say that
child2
handles
the event, yet you also say you add the event handler to the
parent
container, nor do you show any code to remove the handlers or
the
children.

in my module's creationComplete handler I have this code:

This handler never gets hit.

This is probably a dumb question but... I am trying to do a Flex app primarily in AS.

I assume that I need to put the x=5 (hence the left=5) and then do the math to find out the 'stage' size and subtract the other side (5) for the width. However what do I use to do the math? I tried Application.application.stage.width, but I keeping getting a null value error. How can I detect the size of the swf at 100%x100% and do the math or is there an easier way to do this. Didn't see a mainACB.right. Here is what I do have: var mainACB:ApplicationControlBar = new ApplicationControlBar(); mainACB.x = 5; mainACB.y = 65; mainACB.height = 30; mainACB.width = Application.application.stage.width - 5; Application.application.addChild(mainACB);

#1. I am passing data to a javascript function in json format, which
contains escaped \.
#2. This is the issue.
http://joshblog.net/2008/01/03/flash-player-externalinterface-variable-name-bug/
On this one I tried putting my function call in '' to as this blog
post suggests, but it didn't help.
The JSONENcoder is escaping the and \ on the flex/actionscript side,
but when it is getting passed to the javascript file I don't think the
javascript file is understanding the escaped items. I am not a JS guy
so I don't know if JS/Broswer knows about escaped characters?

[flexcoders] Re: How to register a dynamicEvent in an Actionscript class
Thanks Nate, Tried that but it still doesn't work. I'm basically trying to dispatch a dynamicEvent from a Cairngorm event and then trying to get a module to listen for that event. I don't want this event to be a CiarngormEvent to be handled by the FrontController and the Command object.

While that example does allow you to maximize a panel, it does not expand the contained objects.

[flexcoders] Re: geting info of a user who has loged in
I use PHP and WebORb for PHP so anything I show will use that.
Please do not ask for a tutorial using something else.
There should be enough here for you to extrapolate for use with any
language.
This is a quick and dirty example that hard codes things. In a real
application
I would loosely couple everything with events.
My Flex project is set up with a couple of folders called components and
ValueObjects.
The main Application file (login_example.mxml):
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
layout=absolute xmlns:view=components.*
applicationComplete=doApplicationComplete()
mx:Script
![CDATA[
import ValueObjects.UserCredentials;
import components.*;
import mx.managers.PopUpManager;
import mx.core.IFlexDisplayObject;
private var myLoginForm:IFlexDisplayObject;
private function doApplicationComplete():void
{
myLoginForm = PopUpManager.createPopUp(this, login,
true);
}
public function
doLogin(userCredentials:UserCredentials):void
{
viewstack1.selectedChild = admin;
admin.userCredentials = userCredentials;
}
]]
/mx:Script
mx:ViewStack x=0 y=26 id=viewstack1 width=100%
height=100%
view:Home id=home/
view:Admin id=admin/
/mx:ViewStack
/mx:Application
This has a view stack for each view - Admin and Home. There are also a
couple of functions.
doApplicationComplete is called on applicationComplete event and
instantiates the login
window. doLogin is called from the login component if login is
successful. It poulates the
userCredentials variable of the Admin component.
==
components/Home.mxml:
?xml version=1.0 encoding=utf-8?
mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml;
/mx:Canvas
This is just a container for the background of the login window at
startup.

When I dynamically create columns it stretches to beyond the origional area. This behaviour has been reported as a bug. http://bugs.adobe.com/jira/browse/SDK-14390. The workarround described in the bug setting the width to 0 works for me in a simple test case but doesn't appear to work within my main application. [...] I would like to extend datagrid with a version that doesn't have this issue if I can figure out why a fixed width doesn't work. I've left a reply on the bug: http://bugs.adobe.com/jira/browse/SDK-14390 Basically your DataGrid's minWidth is too large for the Panel. You can set the minWidth property to reduce it. By default the measured value for minWidth is always going to be large enough to accommodate all the columns. Manish Okay sorry If I wasn't clear enough about it basically the data grid stretches, but not enough to accomidate all columns. Nor even enough to fill the container. Setting a width of 0 makes the datagrid remember its constraint layout. Some other intresting factors in my test case if I leave on column not dynamically created specified in the mxml, and replace it with the dynamic columns then it works correctly. The other point is that it still occurs even if horizontal scroll policy is set to on. (Which is actually the way I want it to work). Again I got this reply when I was at home so it will have to wait until tomorrow if I produce a test case. My test case was simply adding a data grid to an application and either giving it a right constraint or a percentage width. The I created a loop and created an array of DataGridColumn headers. Then I set this array as the datagrid column array. Anyway thanks for your time Manis. Wesley

Re: [flexcoders] How to create universal event handler?
- Original Message - From: Dan danijel.arsenov...@gmail.com To: flexcoders@yahoogroups.com Sent: Monday, January 12, 2009 6:24 PM Subject: [flexcoders] How to create universal event handler? I have class MyEvent extends flash.events.Event. I also have a second class MyEventChild extends MyEvent. Both classes define string constants that are used as event type. How can I add event listener to handle any of MyEvent or MyChildEvent events? If I do addEventListener(MyEvent.Evt1, handleEvt), I will handle only that specific MyEvent.Evt1 event. I need to be able to handle MyEvent.Evt2 and MyChildEvent.Evt1 and my FutureChildEvent.EvtX. How can this be achieved? Is this really a good route to go down? Your universal event handler will turn into a big switch statement and will be responsible for handling whatever is thrown at it. The difference between having separate events (most likely custom events) is that the handler method is invoked in the correct context for the event and that handler method only needs access to data structures that need to be changed for that specific event. The event and handler only change in response to changing circumstances regarding that specific event (in the future it may need to carry some extra or different data). If you have a universal event handler, the handler function has to have access to all the data structures to be manipulated in response for all the 'subevents'. The universal handler must be changed every time an event is added, or changed. It seems as though the universal handler scheme just avoids the creation of individual events and handlers in favour of putting that same effort in one basket rather than have the flexibility of separate true events. Effectively you are building a controller mechanism inside of a single event handler. Paul Thank you!

To deselect the other rows, the checkbox column header renderer calls a 'selectAll()' method on the CheckBoxDataGrid with a flag of false. That method builds two arrays - one for all items in the collection and one for all indices in the collection. It then replaces mx:DataGrid.selectedItems and selectedIndices with new arrays. In the deselect case, the new arrays are empty. In the select all case then have all items/indices. Visually, selectAll true/false seems to work when it's called.

I started with Alex' example. Then I added a header renderer on the checkbox column such that if check the header, then all rows are selected. To implement the select all behavior, I'm creating an array of indices for [0..n] and assigning that array to mx:DataGrid.selectedIndices. For the most part this works fine. But if the DataGrid is editable, then I sometimes have a problem. The problem is that if all rows are selected, and you click on an editable cell, sometimes the cell becomes editable without deselecting all of the other rows. The behavior I want is that if you start editing a cell, then just that row becomes selected. This happens some of time, but not all of the time. If the grid is non-editable, then I can't reproduce the problem. I overrode mx:DataGrid.selectItem() in order to clear the checkbox in the header renderer any time a single item is selected. I've noticed that when the problem behavior occurs, the mx:DataGrid.selectItem() method is never called. It's almost like there's some race condition between selecting an item and starting a cell edit. Any ideas on how I could work around this? Thanks, Glenn
