[flexcoders] Re: Bind to Dynamic Component or Panel
I am on the path of creating an associative array with reference to
the objects (which is this case is a datagrid).
However I can't seem to figure out how to update the data provider
when a new message is received from my source. Here is how I create
the GUI dynamically.
CONFIGARRAY gets populated from a DB query. I then loop through
creating a panel with a datagrid. At the end I add the panel to the
canvas for display.
Can someone advise how I could reference the datagrids to bind new
data to them when a message is recieved from the server. This step
would obviously occur based on an event listener.
Basically what I need to do is say something like (if message contains
msgType1 then send the message to datagrid1)
Here is the gui creation code:
for ( var i:int = 0; i CONFIGARRAY.length; i++)
{
var panel:SuperPanel = new SuperPanel();
var datagrid:DashBoardADG = new DashBoardADG();
datagrid.percentHeight = 100;
datagrid.percentWidth = 100;
datagrid.id = CONFIGARRAY.getItemAt(i).Panel_Name;
datagrid.dataProvider = dataFeed;
panel.title = CONFIGARRAY.getItemAt(i).Panel_Name;
panel.showControls = true;
panel.enableResize = true;
panel.width = 400;
panel.height = 150;
panel.x = X;
X = X + 410;
panel.y = Y;
//
if (panelcounter 2) {
Y = Y + 160;
X = 0;
panelcounter = 1;
}
panelcounter++;
panel.addChild(datagrid);
PANELARRAY.addItem(); //ADD something for reference to datagrid
this.MAIN2.addChild(panel); //MAIN2 is a canvas
}

I would instead advise that when you create the child, you place a
reference to it in some kind of dictionary structure, like an array,
an associative array(object), or dictionary.
Use that reference to access public members, add event listeners, etc.
You will not need to worry about where it is in the dom.

Oscar,
Thanks for that. That is basically exactly what I needed. The one
problem I am running into is that I want my panels to be only 3 wide
on the page and I have 12 entries in the DB. So I am creating a
page 3
panels wide and 4 panels down.
To do this I create a new HBOX every 3rd Panel.
so I need a way to figure out which HBOX the panel is in. Then I
can do
HBOX3.getChildByName(My Panel)
The way I am starting to do this is by creating an array collection
that keeps the Panel Names and the childIndex for the HBOX and the
Panel.
What would be nice is if you had a Canvas and and it didn't matter
how
many levels deep the panel was (i.e the panel had a global bindable
name)
Then you could do Canvas.getChildByName.
I can post code if that doesn't make sense.
[flexcoders] Re: Bind to Dynamic Component or Panel
It sounds like getChildByName is what you need: yourContainer.getChildByName(panel1) Regards, Oscar http://www.holaflex.com http://www.holaflex.com --- In flexcoders@yahoogroups.com, gjessup1 [EMAIL PROTECTED] wrote: I am creating a UI that gets configured from a database. For each DB entry it creates a panel dynamically. Then I have my app receiving messages. Based on the values in the message I decide which panel I want to display the message on. My question is when a panel is dynamically generated. How do I reference it so I can bind to it. i.e panel1.addChild(some object); Is there a getelementbyid reference. Does anyone else have a gui like this they could explain how they are doing it. thanks Greg
