Flex :: Make A Custom Component Or Extend The List Component For A 2D Top Down View MAP ?
Nov 11, 2010I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?

View 1 RepliesFlex :: Extend SWFLoader Component To "fit" Any Sized Image Inside It?
Feb 21, 2010SWFLoader's scaleContent is not able to do what I'm trying to achieve:
<mx:SWFLoader id="img" width="600" height="400" scaleContent="true"/>
When an image of size 100x80 is loaded inside it, the image does does not resize to 600x400. That's because scaleContent = true.
Then, I set maintainAspectRatio = true. The image did resize to 600x400 but obviously, it was totally out of proportion.
So how do I always fit any sized image to the current size of the SWFLoader while maintaining the aspect Ratio? The resized image may be cropped, which is ok.
SCENARIO: An image of size 1500x10 is loaded inside the above SWFloader. In this case the height(10) should be resized to 400 and the width(1500) should automatically resize depending on the height. A lot of the image will be cropped, which is fine.

Flex :: Hide A List Component When It Contains No Items?
Apr 28, 2010I have a List of items which is based on the contents of the "category" that a user selects
When the user changes selection, I change the dataProvider of the list be be the contents of the current category.
Sometimes the list contains items, sometimes it does not
Is there a way of hiding the list when it has no items?
I know that I could do this when setting the dataProvider, but it seems like there should be an event or something else that I could be using.

View 1 RepliesFlex :: Creating A Custom List Component
Jan 10, 2011I'm trying to extend the mx:Box container so that two buttons sit on the outside of the container to cycle through it's contents (similar to a scrollbar).
I've made a custom component that looks basically
like "mx:HBox->mx:Button mx:Box mx:Button" where the buttons and box are children of the hbox.
How do I offer the user access to the box (say its dataProvider and itemRenderer) through my custom component?
So they just need to write 'local:MyCustomComponent dataProvider="rar" itemRenderer="rar"/>' and my box inside that component can use it?
Actionscript 3 :: Is There A Hierarchical List Component For Flex
Jun 9, 2011I will implement this myself if I can't find it but after 30 minutes of searching on the web I'm a bit surprised this doesn't exist.

I want the same functionality as a tree component but displayed as each level having it's own list resulting in multiple lists that depend on each other.
View 1 RepliesFlex :: Creating A Dynamically Sized List Component
Aug 16, 2010I need a List that resizes to exactly fit its content, unless that height exceeds its (dynamically sized) parent container. My requirements are as follows:
The component extends List, or at least acts similarly. variableRowHeight and wordWrap both equal to true. The height of the list cannot be less than minHeight (roughly 32px for scrollbar arrows). The height of the list cannot be greater than the height of the parent container .
Note that the parent container can be resized dynamically.
The height of the list should be updated as the size of both the contents and parent container changes.
Live updating would be preferable but not necessary.
There should be no scrollbars if the content height is less than the parent container height (sounds obvious, but I've had trouble with this too).
The trouble is that with variableRowHeight and wordWrap, it's very hard to know the size of the content at any given time. If the parent container's width is reduced, a line wrap may occur in the list which will change the height of the content. I know I can measure the height of the list content using measureHeightOfItems() + viewMetrics.top + viewMetrics.bottom, but when should I calculate that? What events should I listen for? And the thing I've had the most trouble with - when should I calculate it to set the size initially (i.e. just as the content has finished populating)?

Flex :: Custom Component Not Updating Display List?
Jul 12, 2011I've created a component which is basically a meter (extends skinnable container). The skin to the component contains two rectangles (background and the actual meter). This component receives an arraycollection with the following fields value, max and min(the arraycollection I am passing is Bindable). When I initialize and pass the data to be used to draw It works great (keep in mind - only works the first time). I've created a button that changes the data array and shows the current meter value. Apparently the meter's value is changing everytime I modify the ArrayCollection I've set to be used for rendering.(dont want to say "dataProvider" because it is not a Flex dataprovider, just a variable )... here is the code...
public class meter extends SkinnableContainer {
[SkinPart( required = "true" )]
public var meter:spark.primitives.Rect;

May 24, 2010I am aware that the follow will show a hand cursor:

So how can I show the hand cursor only when rolling over the list items?
