Re: [flexcoders] Keep combobox open to allow multiselect
Ram,
The component you are trying to create shouldn´t exetend the combobox
for two reasons, first you would have to override a lot of the
combobox methods and second (and for me the most important) you would
break the common sense of how a combobox should behave for example if
it doesn´t close when you select an item when it closes? What you are
going to show when the user select five items?
If I where you I would make that componente based in the canvas or the
vbox container and give it a diferent look form the combobox (after
all as I said the feel is alredy diferent), you could use a label and
a button (for the closed look) and a list with checkboxes itemEditors
(for the opened look)

Hi
I have created a combo box with a checkbox renderer on each of its items.
When I select an entry in the combobox, the box closes automatically.
I want to prevent his so that I can multiselect elements in the combobox.
Is there a way to do this? Even if I extend the ComboBox and override its
close method, the combobox still closes (and I realized that there is a
private method in ComboBox.as called destroyDropdown() which gets called
when the collection that the combobox holds changes.
Thanks
Ram

Re: [flexcoders] Re: Is there a flex based Tag Cloud component?
Jeff, You can use the flowContainer component http://blog.3r1c.net/?p=89 to easely create a tag cloud component, all you need to do is add the methods to calculate de size based on your ratings. You can use a repeater based on your array.

The question is what component can I lay it out in so it auto wraps. Any ideas?

Re: [flexcoders] DataGrid What is the limit?
Nadeem, I think you are confusing datagrid row count with datagrid´s dataProvider length. When you ask: What is the maximum row count that a DataGrid Component can display at a time? You are asking the size a datagrid can get in the screen, that´s why Cato Paus said 5000 X 5000 (5000 pixel of width and 5000 pixel of heigth). About the size of a datagrid dataProvider I don´t know if there is a real limit, I would say that the limit depends of the user machine since most of the processing is done in the user machine. One thing I can tell you if you are going to show that much of data I shouldn´t use any kind of itemRenderer, labelfunction or any other thing that add data management to each row. And if you are gonig to show that much of data you should consider to add a pagging funcionality to your grid.

Re: [flexcoders] Listening for a value change
Jeff, Look at setter and getter functions it´s just what you need.

I have the following String: [Bindable] var myString:String; The value of myString changes throughout the application. Based upon the value of myString I want to perform different tasks. How can I write a listener that determines 1) that the value has changed and 2) what the new value is? Thanks Jeff
Re: [flexcoders] FlexReport not showing report first time in tab navigator
Derrick,
My guess is that you are setting the heigth and width to percent
values, try to set it to an axplicity value.
That´s because flex only know the size that things have when it draws
them, so your percentage values would evaluate to 0.
It´s just a guess but I had the same problem before and it took a
while to figure it out.

I know there are many here who use FlexReport library so I hope somebody
here can help with this. I am loading reports into a tab navigator, the
reports do not show content until i switch tabs, then come back to that
one. I suspect the 'show' event being dispatched does something to the
content to make it re-appear but I'm not sure.
When I load a report, I do it with the following lines in my function
//CODE//
var viewer:ReportViewer = new ReportViewer();
viewer.reportLabel = item.label;
viewer.reportClass = item.data;
viewer.label = item.label;
reportsTabNavigator.addChild(DisplayObject(viewer));
//END CODE//
ReportViewer just loads reports dynamically like so
//CODE//
private function generateDocument():void
{
var productivityReport:ProductivityReport;
var productivityReportDP:ProductivityReportModel;
//it's only setup for 1 report now, the ProductivityReport
//get the names of the report and dataprovider classes

var

[flexcoders] opinion about flex module
Hi, I´m working on an application that by the flex documentation it´s a great candidate to use flex module. It´s a big application where the user is only going to use one of its features each time. I´ve seen a lot modules topics on this and other lists tha I subscribe talking about problems with this aproach so I´m not so sure anymore if it´s a good idea to use it. Thats why I would like to hear from who has used it what they think about it. What are the pros and cons? Is it easy to pass information from one module to another? and things like that. Thanks in advanced Felipe
