Flex 4 Custom Component - Notify Skin Of Property Changes?

Jan 30, 2012

I have a custom Flex 4+ component that I am trying to make and have the skin be aware of changes to a custom property. This property will determine the graphic on the button (and some other visual changes) but the data will change constantly as it will be updated by a timer.

I've looked at untold examples and still seem unable to get the syntax correct or discover how things should be separated. I've looked at overriding commitProperties and the PropertyChangeEvent without success. So I have two questions.

1) How can I get a skin to be notified of a bound property when it changes?

2) If the data for a bound property of the component is an object, will binding work properly if a property of the object changes (or would it be better to pass each property separately)?

Unable To Bind To Property Of Custom Component

Feb 25, 2010

Can't seem to bind to data from within a custom component. I've tried BindUtilis and {} but can't seem to fathom it out. Here's what I've got:

I have a class DataModel which has been made bindable

Within Mainn.mxml I have two components: DataGrid (used for testing) & CustomComponent (which extends Canvas)

When the data within DataModel.somelist is updated the DataGrid reflects the changes but the CustomComponent doesn't appear to.

I was expecting to see the trace (CustomComponent.dataProvider) fired whenever this._dataModel.itemList is changed. [code]...

Flex :: Change Values Of Custom Skin At Run Time?

Mar 5, 2011

I have built a basic theme for my Flex app. I would like to add support for additional predefined themes. By default, app has a theme and I would like it to change when user selects a theme from dropdown list. This can be done by loading a swf file using styleManager. However, all the skins have colors hard-coded in them. So, in order to achieve this I would have to duplicate skins and change value of the colors.

Is there a better way of doing this? Can I just have a skin that will change color values dynamically based on user selection?

Actionscript 3 :: Flex 4 Disptaching Custom Event From Custom Component (why Flex Converting Custom Event To Mouseevent)?

Mar 2, 2012

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;

Flex :: 4 - Create A Skin For The Component Scroller

Jan 7, 2011

I'm trying to skin the Scroller in my application so that it looks like the example mentioned in [URL] This example was done in Flex 3 and images are set in CSS. I tried to create a skin for the component Scroller and saw that it uses VScrollBar and HScrollBar. I tried to put skins for these components. VScrollBar uses separate skins for the track, thumb, decrement/increment buttons. I tried to make some changes in the skin, but they were not reflected at all in the application. I just want to create a customized scroll bar in Flex 4 with custom thumbs.

Flex :: Custom ProgressBar Bar Skin Won't Fill Entire Track?

Apr 14, 2011

I'm trying to create a simple skin for the flex progressbar control. Both the track and the bar should have rounded corners, and the bar should fill the track completely in the parts where it is being shown.

Here is the bar skin I've created based off this example:

<?xml version="1.0" encoding="utf-8"?>
<s:SparkSkin
xmlns:fx="http://ns.adobe.com/mxml/2009"

[Code]....

Instead of the bar being flush with the track, there's a margin, and the rounded border gets cut off.

Flex :: Can't Show Rounded Corners On Custom Panel Skin?

Aug 12, 2011

I wanted to change the background color of my Panel title area and I discovered that I needed to create custom skin or skin extender to accomplish this. So I created a skin called myPanelSkin based upon the Spark.PanelSkin. My background color works fine but it will no longer show the cornerRadius defined either on the component or in a styleI then tried another approach and simply created a new skin as an exact copy of the Spark.PanelSkin. It also looses the cornerRadius.

Flex :: Use Custom Background Skin On Datagrid Header For Currently Sorted Column

Apr 26, 2011

I use a flex mx:datagrid. I can set the headerBackgroundSkin to specify a skin or a picture to be displayed in all datagrid column's headers and it works just fine !

The problem is I can't find any way to specify a custom skin for the currently sorted column (doesn't matter if the sort is asc or desc, this is just to show the user which column is currently sorted).

I also tried to create a custom headerRenderer for each column but it is quite complicated and doesn't work very well.

I have been looking for the solution for a while but I can't find a good approach to do it. It sounds like a very basic need for me...incredible it is so complicated to achieve with Flex !!

I noticed someone was looking for the same thing few years ago but without success... [URL]

Flex :: Make A Custom Component Or Extend The List Component For A 2D Top Down View MAP ?

Nov 11, 2010

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?

Flex :: Define Custom 'contentGroups' In A Custom Flex 4 Component?

May 12, 2010

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?
