Flex :: Mediator Must Hold View In PureMVC?
Dec 28, 2009I have one question about pureMvc. I use pureMvc to build an engine, in the engine init part i have an requirement
1) moduleA must init firt
2) moduleB , moduleC need init after moduleA init complate.
3) moduleD need init after moduleB & moduleC init complate.
4) moduleA , moduleB , moduleC , moduleD all extends Proxy beacuse the four system all need to send notifiation ,but no need to listen it.
But to fit for the requirement I can't use command to do it, because they have ini order and also they need to remember current state(ex: moudelB is init Complate but moudleC is not init complete then can't init moudleD) but command is stateless. The best way I think is use one Mediator to do it, beacuse it can both listen and send notification. My question is :
1) Is this a good way to use one Mediator to do it?
2) If use Mediator is good way, then when it hear first moduleA is init complate
registerCommand(FIRST_MODULE_INIT_COMPLATE , initStepTwoCommand);
sendNotification(FIRST_MODULE_INIT_COMPLATE);
removeCommand(FIRST_MODULE_INIT_COMPLATE);
Need to do things like that way or just do the inti logic in the Mediator?
Flex :: Creating RobotLegs Module Within A PureMVC Shell Application
Oct 19, 2010I'm working on an existing modular project that was built in PureMVC. Instead of converting everything over to RobotLegs, I want to create a new module using RobotLegs and plug it into the pureMVC shell. Currently, when the module loads, I get the following flash error: ReferenceError: Error #1065: Variable IMediatorMap is not defined.
Inititally, I thought it was because my module needed a pureMVC Mediator to call the pureMVC StartupCommand to get things "hooked up" and THEN create the RobotLegs' Context. However, that didn't work and I'm still getting the error.
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 13 RepliesActionscript 3 :: Recursive Flex View Component?
Sep 15, 2011I have a Flex component that is a view of a data Object that recursively has a reference to itself.
For example if you had an Employee class that references a boss field of type Person, I'd like to nest the same view for that Boss. This shouldn't be an infinite recursive relationship (e.g. I'd only be viewing the boss field of each object).
I've tried creating an MXML component that references itself but when I run it locks up (seems like it gets into a recursive loop).
Is there anything you can do like includeInLayout conditions that will make sure it doesn't even instantiate that component.

View 10 RepliesFlex :: Scroller - How To Bring Contained Component Into View
Aug 28, 2009I have lots of child text inputs within a spark Scroller. How can I make the TextInput with id of "x" come into focus if I have a..z id's, also for the scrollbar to scroll automatically to that child item? I can use x.setFocus(), but the scrollbar doesn't automatically scroll to that item? why?
<s:Scroller id="scroller" width="100%" height="100">

<s:TextInput id="a" text="" editable="true" width="100%" height="25" />

Flex :: RichEditableText Component Not Completely Resetting Its View
Mar 1, 2011I'm experiencing some strange text rendering behavior in the Spark RichEditableText component.
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx="[URL]"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
[Code] .....
The above application simply navigates through the five sentences in the DATA array (every time the Next button is pressed). For whatever reason, RichEditableText component doesn't completely reset its view (by clearing the previous text) before setting new content. From what I can gather, this faulty rendering is somehow based on the combination of line count and relative width. I also discovered that if I set the width property of the RichEditableText component to an absolute value (say, 100) as opposed to relative (percentage, 100%) the text is rendered correctly. As far as I can see, this behavior is unintended and is, in fact, a bug.
Actionscript 3 :: Refer To A Spark View Component In Code?
Nov 12, 2011I'm building a mobile AIR app using Flash Builder 4.5. The initial view in my views package is TestHomeView.mxml. I want to refer to it in one of my .as classes elsewhere in the app, and I'm not sure how to do that.
Theoretically I should be able to add an "id" attribute to TestHomeView.mxml, but FB gives me an error: "id is not allowed on the root tag of a component". The root tag is s:view.
The reason I need to do this is that within another class I make various calculations and then need to pass an array of values to a component in my view class. So in SomeOtherActionScriptClass.as I first assemble the array, myArray, and then in that class I want to do this:
myViewComponent.viewArray = myArray;
If I'm going to do that, I also need to import the view class into the .as class, which strikes me as weird. So is there a simple way to do what I want, or do I have to dispatch a custom event which contains the array, and listen for it in the view class?
EDIT - Based on the below MVC suggestion I did the following in model:
[Bindable]
public class Model
{
private static var myModel:Model;//doesn't let me name it 'model' because
[code].....
But it is coming back null. It isn't null when I put a breakpoint in the Model class, but when I try to access it from the view class, it's null. The model itself isn't null, but that variable is.
Flex :: Determine Which (custom) Component In A View Currently Has Focus
Nov 28, 2011I'm currently building a Flex 4.5 mobile project including several views and custom written MXML components that can be incorporated dynamically into those views.How do I determine which component currently has focus, namely has been activated by the user tapping on it? The background for this is a global search function in the main application. Depending on the results of this search, fields in the custom components are set. Given that I don't want all components in a view to listen to the outcome of that search function, I have to check which one is currently active.I'm trying to bind the selected object (the result from the search function) to the active component.

Apr 1, 2010Do you know how if you drag an <mx:Label> or <s:Label> component into your Flex project, when you go to design mode you get this panel on the right to set its properties like text etc.
I have a custom component that I can call with actionscript, or with mxml like this:
<comps:TheComp field1="OK" field2="Yes" />
The component takes this input and uses it for its internal operation
[Code]...
When I go to design mode, I can see the component under custom components, I can drag it to the stage and see it, but can't set its values field1 and field visually on the right like a normal <s:Label> or <mx:Label> would have. how I can add that? Do I need to make it inherit something or anything else

View 1 RepliesFlex :: Run ClickHandlers On Buttons Moved From Main View Component To Header Bar?
Jun 7, 2011I've used JRab's example here [URL]... to add a header menu to my app. What I'm having trouble with is executing my functions from the header mennu. For example, my firstView is appHome.mxml. It instantiates a Canvas object that has an erase(). There is a button in appHope.mxml that executes the erase() on the Canvas instance. I'm trying move the Erase button out of my appHome.mxml and into my headerMenu.mxml but don't know how to execute the erase() on the Canvas instance. The first thing I thought to try was click="{appHome.myCanvas.erase()}" but obviously that didn't work.
I asked a similar question yesterday here: Flex executing a function on another view and I accepted the answer before I tried it. The problem is that the headermenu.mxml is not a child of appHome.mxml. They are both children of the main app.mxml. Secondly, the object that has the erase() is in a separate .as class I instantiate in appHome.mxml.

Flash :: Flex4 Host Component Have The Same Function As A View Mediator/helper?
Jul 17, 2011Coming from Robotlegs/PureMVC, I am pretty familiar with the concept of the view mediator, i.e. a component that pretty much listens to events/requests coming from the "dummy" view and makes a further request, sends an application-wide signal/event, executes a command, etc, based on the request from the view. Can the host component idea introduced in Flex 4 be considered a the same as a mediator? The only thing that slightly bothers me is that host components are still considered views, because they extend SkinnableComponent or any of the classes that further inherit from it. In my view, the mediator should be completely left out of view logic.
Nevertheless, I do not want to write a skin, a host component, and a view mediator for that host component, because that would be quite an overhead, and would lead to more complexity rather than abstraction.Should I use host components as mediators, and put application-level logic there, for instance application level event dispatching?

View 2 RepliesJava :: View Part Of A Web Application - What Technology For A Pretty Intensive Grid View
Aug 3, 2010I'm about to have to write a web page/app that will serve the agenda for circa 100 people on a page. One line per person, one column per day with 3 clickable zones in each cell. In HTML, the page is way complex for the browser to load quick and there is no possibility to click on a border between 2 cells to for example split an event that spreads among several cells. So I search an not too overkilling technology to render this kind of view. I begun with a PHP generated HTML page but the number of elements in the page make the mouse move jerky.
Moving to JAVA would give me better performances regarding the reuse of the generator of the view but it will still be an HTML page. So, here is my question: do you think that going forward with JAVA and its graphical capability is the simple solution or is Flash a better option for this part of a Web App? I'm afraid of the code I'll have to write in JAVA to handle the GUI presentation as well as the events generated by the 1000's cells plus borders of the page. In Flash, the graphical part seems simpler even if the actions handling is still huge.
Flex :: Presentation Model Pattern Can View Specific Logic Reside In View?
Aug 15, 2011I'm currently using RobotLegs with the Presentation Model pattern to develop a Flex 4 project. I understand that all business logic related to a View resides in the Presentation Model associated with that view, however, I am confused when it comes to View specific logic.For example, I have an indicator that needs to be positioned relatively to list items depending on which list item is selected. Is it acceptable in the Presentation pattern to put the logic that will position the indicator in the View and simply have that logic run in reaction to a selectedIndex property changing in the presentation model?The reason I am considering this is that since the Presentation Model does not have a reference to the view it is difficult to come up with an ideal solution for manipulating view components.

View 9 RepliesActionScript 3.0 :: Creating A Custom Component?
Jun 3, 2009I am creating a custom Component using ActionScript 3. This Component have some properties that can be changed in the Component Inspector, and in this component i create a text field to show a message that the user define in this panel.
So far, works ok. But i want to give a chance to the user choose a font type to this text field, i found in the Component Definition, a option called "Font Name", with this option, you can select a type of font to use.
The problem is to recover this font in my Class of the component. I try to use the Font Class, but it seems that this class was not created for this. My question is: What Class i have to use to recover the selected font from the Font Name option. I try this:
var newFont:Font = "Arial";
[Inspectable(name="Font name", type = Font, defaultValue = "Arial")] public function set corPreloader(fonte:Font) { newFont = fonte; } public function get corPreloader():uint { return newFont; }
ActionScript 3.0 :: Creating A Button Component?
Sep 22, 2010I am creating a button component in AS3, the idea of this button is that you can set its parameters to the name of movie clips you want to use as its images (mouse up/over/down etc).So basically it's a button that you can easily change the appearance of, and this would be reflected in the preview on the stage. I made this component in AS2 and it worked very well and was very useful.
However there is a problem with this component in AS3 - When I create an instance of my button component and try to set images for it (remember these are the names of movie clips in the library which have been exported for actionscript), the preview of the button component does not show the images. When I compile the SWF the button component does show the images ok though.
When my button component redraws itself, it looks at it's parameters and calls getDefinitionByName to create an instance of the correct movieclip. I am guessing that the problem occurs because the movieclip I am trying to instantiate is not in the component's library, it is in the library of the project I am using the button in, so maybe the component doesnt know what that movieclip is?
But it's odd because when I compile/publish the SWF it works, like I said, it's just the preview of the component that doesnt work, and that's kind of the point, being able to get a preview of the button so it can be positioned and sized correctly.
I know I could get it to work by putting the movieclips I want to use for the button into the button component's library, but that again defeats the purpose of this component.
Flash :: Professional - Creating A Component In CS5
Oct 29, 2010How can I create a component using Flash CS5? I have tried to follow various documents I have found on google and went about it in the following way:
1. I created an empty FLA.
2. I created a MovieClip containing some graphics, and named the MovieClip "MyTestComponent" in the Library.
3. I selected the MovieClip's properties in the Library and selected "Export for Actionscript", and made the MovieClip inherit from fl.core.UIComponent.
4. I saved the FLA in the directory "C:Program Files (x86)AdobeAdobe Flash CS5CommonConfigurationComponents" and restarted Flash. At this point I would expect that the MyTestComponent component would show up in the Components panel, but it did not.
5. I tried to publish the FLA as an SWC file and place the SWC file in the same file as above. According to my understanding, both this and the step above should have worked, but it did not.
Creating Tree Component In Flash With XML?
Apr 19, 2010I have created a tree diagram using the 'Tree Component' in flash, and have linked it to my XML file:
<?xml version="1.0" encoding="iso-8859-1"?>
<node label = "Sports Club">
<node label = "Ball Games">
<node label = "Tennis" />
<node label = "Soccer"/>
<node label = "Bassball"/>
[Code] .....
If you haven't noticed yet, the tree diagram is nothing complicated, it branches out as 'ball games' and 'athletic games' with sub categories such as tennis, soccer etc. (or 100 Meter & Hurdles for Athletic sports.) Now I've managed to go this far, BUT, what i'm trying to do is that when the user chooses the subcategory e.g. 'Tennis' from the tree diagram, I need to get text into a blank text-box.
