Flex :: Dynamically Bind Properties Of Components Created At Runtime?

May 27, 2007

I need to dynamically bind properties of components created at runtime. In this particular case please assume I need to use bindProperty. I don't quite understand why the following simplistic test is failing (see code). When I click the button, the label text does not change.

I realize that there are simpler ways to go about this particular example using traditional non-dynamic binding, but I need to understand it in terms of using bindProperty.

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:ns1="Tools.*" minWidth="684" minHeight="484" xmlns:ns2="*" creationComplete="Init();">

Bind A Component To An XML Node Dynamically At Runtime?

Sep 13, 2010

I have a custom component based on mx:ComboBox. Within it I connect to an HTTPService (the url is passed as a paramter) and bind the combobox. Parameters to be sent to the HTTPService are passed to the component. This is working fine. But I want to modify it to make it re-usable with other HTTP service URLs, which return the XML in a different format.

My challenge is how can I bind a custom component to a node dynamically at runtime?[code]...

ActionScript 2.0 :: Setting Component Properties Of Dynamically Created Movieclip?

Mar 2, 2008

I created a movie clip symbol with a user interface in it, using the standard components. It contains various components that I draged on the stage. I named the instances (e.g titleLabel). Then I created an ActionScript class for that user interface. Under the linkage properties of the symbol I specified that class. In the class itself, i declared the attribute "var titleLabel:Label". I thought this would be the same instance from the symbol? But: Trying to set the text of the Label AFTER the movie was dynamically added to the parent does not work. I cannot access any properties.

Here is the example:

My Class for the user interface:

Code:
import mx.controls.*;
class Information extends MovieClip {
var titleLabel:Label; //this is the same instance name as in the symbol

Flex - XMLListCollection Properties In Custom Components Always Null?

Dec 11, 2009

I've written the following custom component, SubNavBar.mxml:

creationComplete="init()">

Whenever the trace function runs in init(), the property menuItems returns null. I don't seem to have this problem with other variable types, like Boolean or String. Is this due to the size of the XMLListCollection object? How can I set up this SubNavBar custom component with XMLListCollection property and bind it to a control in the component?

Flex :: Accessing Properties Of AdvancedDataGrid Runtime Vs Design Time

Jun 12, 2011

I am new to Flex and trying to modify some existing code.I am trying to It uses and Advanced DataGrid. In the click event, the ListEvent is passed in, and the code is able to access properties such as event.itemRenderer.data.feature.I would like to check whether the user has clicked on a parent (group) record or the child record; at runtime, I can see that the property I want to access is event.itemRenderer.listData.hasChildren. However, the listData property of itemRenderer does not show up in intellisense, and when I try to access that at design time, the project will not build because of the error "Access of possibly undefined property listData". But the property .data.feature doesn't show up in intellisense at design time either, and that builds and runs just fine.

What do I need to do to access event.itemRenderer.listData without throwing errors when I build the project? Do I need to capture a different event, or cast the event object or one of its properties into another object that will have the properties I need at runtime (I've investigated these options but cannot find info on how to do that).

Flex :: Getting Handles To Dynamically Generated Components

Nov 10, 2009

I have a Flex application which references a separate MXML file as a template for a custom component. I create instances of the component dynamically several times in my program, but I need to get a handle that will allow me to modify that instance of the component as desired. I pass specific information to this component on instantiation using bindable public variables in the component's MXML file. I add it to my main program using addChild().

I want to update the component's progressbar as necessary and I want to remove it from the box to which I addChild'd it. What's the easiest/best way to get a variable that will give me predictable access to each component so I can easily manipulate the components as necessary? Some research suggests creationComplete, but I decided it was faster to just ask than to go through lots of different experiments and come up blank.

ActionScript 3.0 :: Targeting Dynamically Created MC Within Another Dynamically Created MC?

Feb 17, 2010

I'm dynamically creating movieclips with dynamically created movieclips inside them and am having trouble with targeting them.Below is a simplified example of what I'm trying to achieve, in the real file there are a lot more movieclips and I'm creating and naming them with a for loop.

This one is just one Sprite created inside another sprite. I can target the top level sprite named "testname". However when i try target the nested MC it throws an error.The bottom couple of traces are just test MCs I've made to make sure i got the syntax right, on targeting nested movieclips.

PHP Code:

var holder:Sprite = new test1();holder.name = "testname";this.addChild(holder);var holder2:Sprite = new test2();holder2.name = "testname2";holder.addChild(holder2);trace(getChildByName("testname").x); //this one traces finetrace(getChildByName("testname").getChildByName("testname2").x);//this throws up an errortrace(testclip1.x);trace(testclip1.testclip2.x);

Actionscript :: Dynamically Adding Child Components To Canvas Vs Group In Flex?

I've a custom component where I do some graphics (e.g draw a line) and dynamically add a subcomponent (e.g a label) to it.

If I base the component off Group (which is recommended as per docs since its a spark component) then when I dynamically add a label the graphics part disappears.

However if I base it off Canvas this doesn't happen.

Why is that the case?

Here is the code.

Actionscript 3 :: Dynamically Instantiate A Class / Set Property At Runtime In Flex 3?

Feb 17, 2010

Using org.as3commons.reflect I can look-up the class name, and instantiate a class at runtime.I also have (non-working) code which invokes a method. However, I really want to set a property value. I'm not sure if properties are realized as methods internally in Flex.I have a Metadata class which stores 3 pieces of information: name, value, and type (all are strings).I want to be able to loop through an Array of Metadata objects and set the corresponding properties on the instantiated class.[code]I realize that I have to declare a dummy variable of the type I was to instantiate, or use the -inculde compiler directive. An unfortunate drawback of Flex.Also, right now there's code to account for typecasting the value to it's specified type.

Flex :: Control Dynamically Created Containers?

Dec 29, 2010

I'm new to Flash Builder 4 and Actionscript 3 (actually, to programming as a whole beyond some very simplistic stuff). I have watched / read a bunch of tutorials, and started a project but now seem to have hit a wall. The answer is most likely simple, but seems to be alluding me.

How do I (or What approach should I take) to control visual elements, for instance, BorderContainer's, that I created dynamically?

As is, I have an Application containing a BorderContainer and a DataGrid. At runtime, 3 new BorderContainers (which are dragable, and resizeable) are created based on XML data that contains X & Y co-ordinates, and Height and Width values, and then added to the pre-existing BorderContainer. How would I go about getting the properties of these children BorderContainers to be displayed and remain up-to-date in the DataGrid (such as when they are moved/resized)?

Flex :: Get Width Of Dynamically Created Custom Uicomponent?

Jul 15, 2009

I have some custom components, that derived from UIComponent. I overloaded the updateDisplayList so they have custom look. I've created a layouter that lays out these custom components, but to place them correctly, I have to know the custom componets width, height. They are created dynamically. After all of them created (creationCompleted event fired for every), i try to laying out them, but width/height property is still 0. I am also tried to add them to a canvas, before the layout process.

how to create custom UIComponent that placed dynamically, and get to know the width and height of it.

With the use of the mx_internal namespace I can set width and height (using the internal $width and $height fields), and it looks like it is working. But not so clean/good solution.
