UIComponents have a visible:Boolean property which you can set to true or false.

You can tell whether a Container is scrollable by checking whether its 
maxHorizontalScrollPosition is greater than 0.

2009-07-28 Thread Gordon Smith 
The compiler wouldn't have a declaration of 'data', so would assume item.data 
has type *. At runtime it would have type int if its value is 1. But you could 
use class to define data items with strongly typed properties:

public class MyItem
{
public var label:String:
public var data:int;
}

and then the compiler would know that 'data' is int at compile-time.

The same way you dispatch any other event: Construct the Event instance, set 
its properties, and then call dispatchEvent() on the object that the event 
should be dispatched from (which generally is 'this'):

var mouseEvent:MouseEvent = new MouseEvent(MouseEvent.MOUSE_DOWN);
mouseEvent.localX = 10;
mouseEvent.localY = 10;
...
someComponent.dispatchEvent(mouseEvent);

You can try dispatching MouseEvents, but I'm not sure that they'll work exactly 
the same as a Player-generated one.

That's not how list-based components work. You don't add event listeners to 
data items. You listen to events dispatched by the list itself.

What are you trying to accomplish with your event handlers?

RE: [flexcoders] Re: Question about a flex component

2009-07-24 Thread Gordon Smith 
You add child components which are UIComponents to a container like HBox.

But you add data items to a list-based control like HorizontalList. These data 
items then get displayed by item renderers, which are children which get 
automatically created to display data items. The children are managed by the 
list, not by you... you manage the data, not the renderers.

By default, data items are expected to have a 'label' property to display, 
unless you set the labelField or labelFunction of the list component. They can 
be plain Objects, or  instances of data classes, or anything else, but  
typically they aren't visual components.

Here's an example of adding two data items to a list using ActionScript.

myList.dataProvider = new ArrayCollection();
var item:Object;
item = { label: "One", data: 1 };
myList.dataProvider.addItem(item);
item = { label: "Two", data: 2 };
myList.dataProvider.addItem(item);

RE: [flexcoders] Re: Question about a flex component

You must use the collection API to add the items in order for the necessary
events to be dispatched to update the UI.

 

What is the data type of you dataProvider?

Please help. The items are being added dynamically to the  I debugged the code and the
items are being added, but I can't see them in the UI.
If I change mx:HorizontalList to mx:HBox I can see the items
in the UI. What am I doing wrong?

No, I don't have an example and don't have time to create one for you since I'm 
a development engineer, not a support engineer.  But here is what you should 
try, learning as you go:

1. Create an app with an .
2. Make it show data items by assigning its dataProvider. Put in more data 
items that will fit.
3. Turn off its scrollbar by setting horizontalScrollPolicy="off".
4. Create s for "Previous" and "Next", positioned to the left and 
right of the HorizontalList.
5. In their 'click' handlers, put code like 
horizontalList.horizontalScrollPosition += 1. Use -= for the Previous button.

Do you mind posting an example. It sounds like this is what I was looking for. 
I need a horizontal list component with an icon at the right end of the 
component that I can click and scroll to more items.

Thanks,
