I am trying to define the content area of a custom component that extends mx:VBox. The component has predefined headers and footers (visual children) and I want to set the area in the middle for adding children to the component. The component will be used like this:
<custom_component>
<mx:button/>
</custom_component>
How would I set this content area?
I am trying to develop a custom component to act as a divider.

I would like to use this component to assign objects like this:

Unfortunately, this does not work. I get a compiler error saying: In initializer for 'left': multiple initializer values for target type mx.containers.Canvas.
How do you set the default value of skinClass for a custom component in Flex? I've extended the DropDownList with my custom component, but I would like to specify a default skin to go with it instead of always setting the skinClass value for each instance.
View 1 Repliesi never use compenents, and was recently asked to build one. Ha. Anyway, i have a working class that does all i expect, however, when transforming the class to a component, i am having trouble getting the inspector to actually 'set' the variables. below is a very general idea of what i am doing. All the variables show in the spector, but only the default values are working at runtime.

This is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent.
dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
This is my custome event
package events
{
import flash.events.Event;
import ui.map.MapElement;

In the main file, I would write[code]...
But if I want the component to have that behaviour innately, where do I write it in the mybutton mxml file to have it reference itself?[code]...
I'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?
I have a custom Flex 4.5 component (to be used in a List) -
Game.mxml (represents a clickable playing table in a card game):
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer [code].......
But I never see the "game clicked: " trace. Does anybody please know why? I'm probably missing something minor, because I can see the "Clicked: 8946" trace.
This is similar to the question asked here. I am dispatching custom event "ShopEvent" but i am getting error "Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent"Note: Error is thrown from the parent custom component (3rd code snippet), I have added more details thereThis is my custom event. See the first constant, I copy pasted the event name in custom components.
package com.events
{
import flash.events.Event;

The spark panel component for example can be written like this
<Panel title="Skinny">
<child components ... />
<controlBarGroup>
<child control bar components ... />
</controlBarGroup>
[Code]...
The motivation here is that I can now create a couple different skin files to change the look and layout of those subgroups. Reading source of the spark panel, there are some calls within the mx_internal namespace such as getMXMLContent() which is a method of the spark group component, but which I have no access to.
Does the description above make sense? How can I create custom 'contentGroups' in my custom Flex4 component that can use nested mxml child components? Should I approach this a different way?
How do I get the size of the content area of Container objects? One non generic solution is checking for styles I suppose but I am looking for some code that works generic for all standard flex Container objects. The controls are Flex 3
View 1 RepliesI created a custom MXML component, TurboContent, that extends the NavigatorContent class:

In this case, the 'myButton' component never shows up, but all the elements of the base component do (3 buttons and a datagrid).
I am trying to set the json content type on httpservice to make REST service return the json data. When I add the content type in fiddler all works fine so the problem lays in flex application, not in the web-service. But the code below does not work and I get the xml data instead of json.
mxml:
<s:HTTPService id="service" method="POST" url="server.com" result="loaded(event)" fault="fault(event)" useProxy="false" resultFormat="text">
Actionscript:
public function loadAllSamples():void {
service.contentType = "application/json";
service.send('something');
}
I am trying to determine the global coordinates of the visible rectangle that is currently rendered on the stage.
Specifically, if a canvas has an explicit height and width and is a child of a panel that has a scrollbar, the scrollbar can "hide" a part of the canvas. ContentToGlobal(x,y) provides the global position of the content at the time, but content coordinates can scroll off the boundaries of the parent panel and continue to give x,y coordinates that are not visible.
Is there a way to determine the viewable rectangle that is not hidden by anything?
Beginner Question: I am using the IFrame Component for Flex in Flex 4. The code below works when it is put at the top of the scrolling area. However, if I put it where it below the viewable area it will not render. I am a complete beginner to Flex. The interesting thing is when I resize the window while the HBox is in view, the Iframe will load. But scrolling to it will not. Below is my code. I have made sure everything is visible=true but it seems like I need to add a listener or somehow trick it to think that the window has been resized to get it to render. Anyone with an idea how to fix this?

View 1 RepliesI am loading a component which makes a HTTPService call to get data that will then be used to set certain variables in the component. I make the HTTPService call in an init() function (for the initialization event) and then set the variables according to the data received in the HTTPService result handler. However, the variables are still null at both the initialize stage and at the creationComplete stage. If I try and read the variables in a creationComp() function (for the creationComplete event), those variables are still null. Is this correct?
I guess I don't understand the flex initialization cycle very well. When are those variables actually set and available to be used? I need to manipulate those variables automatically after the component loads. Is there an event that comes after creationComplete that is appropriate or some other way to approach this? I am using Flex 3.
Things go weird when i tried position a button in titleContent of ActionBar. Set both the "left" and "horizontalCenter" can't move my button.Code as below:

How can I position a Button at the middle of this Actionbar??

I'm making a UI for a component in Flash. I wanted to use Flex and have had no luck getting the onUpdate exernalInterface call to fire properly. I'm referencing the functionality described here: [URL]. First off, I can't embed the SWF in the FLA. It just won't start the Flex SWF. Even using the external swf, it seems that the onUpdate function is either called too early or not at all. Here's what I've tried:
Tying the externalInterfce declaration to the initialize, preinitialize, applicationComplete, and creationComplete events. Sub-classing my application and putting the externalInterface in the constructor. Neither of these options work. When I create a basic AS3 project in Eclipse and put the externalInferface in the constructor, it works as expected.
