[flexcoders] Re: Flex charting question
Well I dont really want another line to appear so much as a gradient area which shows an approved range. So for example, if the chart showed the axis between june 14th of 07, and a particular weight range, like 200-230 lbs. I would want the space between 200 and 230 to be colored a particular color, then a point to appear between there which actually represents the users data, to show them that on june 14th, they were within the acceptable weight range. Doctors have charts like this for children. As your child gets thier hieght and weight measured on the chart there is a colored area, which shows were most kids are within the average, to basically show you if you kid is too fat for his age or whatnot.

[flexcoders] Drawing a box over top of an image
OK here is the deal. I need to take a jpg image, and display it to the user. I need the entire image displayed. From there I need to give the user the ability to click and hold with thier mouse, and draw a box over the top of the image. I can kinda get it to work. I am using the image as the background of a HBox, but it does not display the entire image, it clips the top and bottom. Anyone done anything similar to this? The end result is that I am trying to catpure coordinates on the image to pass to a java backend to display a digital signature section on the image. Any help would be greatly appreciated.
[flexcoders] Re: Drawing a box over top of an image
Using an image tag, I can get it to work, but when I draw the box it shows up 'behind' the image, so that doesnt do what I want. When using an HBox and setting the background image param, the pic is getting clipped. When I set the backgroundScale attribute, to 100% it squishes the image to fit the HBox, which wont expand to encapsulate the entire image.

The popup scenario is not what the client is looking for.
The second option you gave me, does not work either. Instead it puts
the box in the upper left of the screen, and all the items within the
box appear one on top of another. So the items are in the center of
the box, with the username label appearing first, then below it the
password label, then below that the username text input box, so on and
so forth.
I could really use some sugestions on how to get this to work.

[flexcoders] Re: Center alignment problem
OK I figured it out. Basically verticalalign and horizontal align are
for the children of the class not the class itself, which was what was
throwing me off.
So I created a custom component based on the box, as the other poster
said, THEN I placed inside the box element a panel, which contained my
login labels, and input text boxes etc.
In the viewstack when I instantiated my box element, I set it up with
vertical and horizontal alignments so that the PANEL inside it showed
up in the middle.
Also the boxs' width and hieght were both 100% of the viewstack.
For future reference.
Thanks to all who helped.

[flexcoders] Re: Event calling in Cairngorm 2.1 - Newbie question.
There actually is a problem in the Cairngorm store code. I found it
when trying to dispatch an event using it.
There are two sections that dispatch events, one works and one does
not. The section with the graphical tile list dispatches a cairngorm
event, but not using the CairngormEventDispatcher to update the details.
The textual list uses a different method, since I had a grid object
updating the details panel, I used that code, and it does not fire.
The rule of thumb is, if you want to dispatch and event that is not
registered on your controller, you do not use the
CairgormEventDispatcher, but the standard EventDispatcher, regardless
of whether or not your event is a cairngorm event.
If you are using the code that resides in the textual product list to
dispatch an event to update the details it will not work, the code is
wrong. Unless they changed it recently. If you download it, compile
it, and run it, switch to the textual view, it will not update the
details panel. However the visual graphical tile list will work.
Because they use different event dispatching.
Hope this helps. This was a problem for me too. This may not be what
your doing, but at least make sure you did not copy the code from the
textual product list to dispatch the event or it wont work properly.

[flexcoders] Re: Event calling in Cairngorm 2.1 - Newbie question.
Hey Kevin.
Well my problem was different than yours but I will answer your
question as best I can.
What I would check are:
Make sure your controller is being instantiated on your Main.mxml
page. Like this:
!-- the FrontController, containing Commands specific to this
appliation --
control:MyController id=MyController /
**NOTE** make sure control: is mapped to the directory you have your
FrontController class in.
If you have the reference to the controller, being instantiated on the
Main.mxml, then move on to the controller itself. Be sure you have a
constructor, and an initialize commands method, that has registered
events, with commands. Using the CairngormEventDispatcher, will fire
your events, but only the FrontController you instantiate will hear
them. At the same time if you are dispatching a CairngormEvent using
the standard EventDispatcher, it will NOT send the event to the
FrontController. This is useful for firing events in a standard way,
for the grid details panel for example, but not when you dont actually
register the Event to a command.
The constructor:
public function MyController()
{
initialiseCommands();
}
The initilseCommands() method:
public function initialiseCommands() : void
{
addCommand( Event1.EVENT_LOGIN, LoginCommand );
addCommand( Event2.EVENT_GET_AUTHENTICATION,
GetAuthenticationCommand );
}
In your commands execute method write a simple popup to test:
execute(){
Alert.show(Testing);
}
Just to see whats happening.
As for your question about the static variables. I dont know that it
makes much difference. I prefer to put mine on the events, simply
because I dont like having a lot of statics attached to my controller,
but it might make sense should you get alot to have them all in one
place. I also do things perhaps a little differently, by creating
general events, such as an AuthenticateEvent, with three Statics, like
LOGIN, LOGOUT, and GETAUTHENTICATED. This way I have one event that
handles multiple functions, but it could get complicated managing it,
should your events require lots of member variables for data payload.
Hope this helps.

I am getting no error message, the event just doesn't fire.
I have also noticed in the store code, that they store the static
event variable

public static var EVENT_GET_PRODUCTS : String = getProducts;

in the Event class, while most other Cairngorm examples store this in
the Controller. Is this just personal preference or is there a more
significant reason for this?

of whether or not your event is a cairngorm event.
If you are using the code that resides in the textual product list to
dispatch an event to update the details it will not work, the code is
wrong. Unless they changed it recently. If you download it, compile
it, and run it, switch to the textual view, it will not update the
details panel. However the visual graphical tile list will work.
Because they use different event dispatching.
Hope this helps. This was a problem for me too. This may not be what
your doing, but at least make sure you did not copy the code from the
textual product list to dispatch the event or it wont work properly.

Are you sure the controller has been instantiated?

[flexcoders] Re: Date Fields and Data Binding.
I did and that worked. I knew the problem could not be as hard as it was turning out to be. The problem was I was being asked to help with another co workers problem. He had in one place the value from the model bound to the text attribute, but the selectedDate was bound back to the model using the binding tag. Since I only saw the selectedDate, I figured since he was having a problem, and was using that attribute, I focus on the other attributes for the field. That was my problem. Thanks for your help.

I am attempting to do something I thought was pretty simple. Using the cairngorm model, basically I have a data instance object attached to the model, and it has a Data Object attached to it. So think of it this way. I am running an application that tracks a list of canidates. So there is a CanidateVO actionscript object, and it has a member variable attached to it called interview date, and its of type Date. I am running a java backend retrieving these using spring and hybernate, and the conversion works fine. The problem I am having is with data binding in a grid and details panel. The grid has an array collection which is attached to the model, and that array contains a list of all the canidates, some that have dates and some that dont. All have member variables, but since all instances have not interviewed they may not have a value in the date field, thus those member vars are null. So the problem is that when I have a particular grid object selected, I see the details of that canidate in the details panel, which is just a panel that contains text fields and a dateField component. Well all the other bindings are working fine, but not the dateField binding. I have set the dateFields text bound to the attribute of the object, and that does not work, and I have set the dataProvider and that does not work, and I have even set a data attribute on the dateField and that does not work. Whats happening is, when I am looking at a particular canidate without an interview date, and I select the dateField, then put a date in it and DONT save the record but go to a different instance on the grid, all the fields are updated except the dateField. The dateField text remains there regardless of the fact that the selectedItem has changed, and the new selectedItem has no date in it. Conversly if I select a canidate who does have a date, the date is displayed, but once I go to one without a date, the date stays in the field. Why is data binding not working for dates? Please help. Jeremy.
