Flex :: Multiple Instances Of A TitleWindow Opened
Sep 27, 2011
My Flex application is one consisting of several "subapps". Basically, the main application area is an ApplicationControlBar with buttons for each of the subapps. The rest of the area is a canvas where the subapps are displayed.Only one subapp is visible at a time. When switching between subapps, we do a canvas.removeAllChildren(), then canvas.addChild(subAppSwitchedTo).It's essentially a manual implementation of a ViewStack (the pros and cons of which are not the topic of this, so refrain from commenting on this).In one of my subapps (let's say subapp "A"), I have a search function where results are displayed in a TitleWindow that gets popped up. Workflow is like enter search criteria, click search button, TitleWindow pops up with results (multiple selection datagrid), choose desired result(s), click OK, popup goes away (PopUpManager.removePopUp), and continue working. This all works fine. The problem is if I switch to a different subapp (say "B" -- where A gets removeAllChildren()'d and B gets added), then switch back to A and search again, when the results TitleWindow pops open, there will be TWO stacked on top of each other. If I continue to navigate away and back to A, every time I search, there will be an additional popup in the "stack" of popups (one for each time A gets addChild()'d).
I'm not sure what to do about it and it's causing a serious usability bug in my application.It's like I somehow need to flush the PopUpManager or something (even though I'm correctly calling removePopUp() to remove the TitleWindow).[code]

Often multiple instances of the view component would be used in multiple places in an application. Each time I do this, I register the same mediator with a different name. When a notification is dispatched, I attach the name of the mediator to the body of the notification, like so:

I am loading an swf created in flash professional cs5 via the loader class into a flex 4.1 application. The flash file contains multiple movieclips that are exported for actionscript and those movieclips exist in many instances throughout the movie.
Iterating through everything, comparing class types seems to be the most easy but also the most redundant way to solve this. Is there any way of using the class name as a kind of global selector to access the clips?
I could also make the sub-clips in the flash listen for an event on which they perform an action, but I am not really sure what might be best.

I have a Flex application which has to be deployed in some server. The typical form of access would be invoking the URL. Should I have multiple instances of the applications running on the same server/ deploying the application in diff servers and using a load balancer for routing? If i must have multiple instances, how to do that? On a given day, the application is expected to get around 2000-3000 hits. What are all the factors to be kept in mind while deployment?

I have an AIR application that uses Singletons to manage global state throughout the application. Works great for what it does (manages a network appliance). But now the client wants to spawn multiple application instances from the first instance so they can manage multiple hardware devices at the same time ... kind of like a dashboard but lots bigger.
As you can guess, I coded myself into a corner with the singletons so if I refactor the application to have a bootstrap class that launches the application logic with a button, let's say, that spawns another window that contains the same application logic, then the singletons are shared across both app windows whereas I would have liked two separate instances.
Is there a way to use singletons ( or something else ) to keep global state but create multiple instances in one application where each instance needs it's own state manager?

I'm trying to create a form that based on the users input would determine how many forms to generate dynamically. I have a base state with a combo box that contains 1-4. Bases on the users selection I would like to have the next state generate the number of forms. So if you user selects 2 and click next - 2 copies of the form would be display.
I'm just wondering if this is possible how i would go about doing this or if any one knows of any examples?

In short: I need an event listener in a custom component so all its instances (without editing them) react at the same time, fired by a dispatched event in its parent container. In detail: I have a custom component with Tab navigator. (The tabs are intended to show different preferences for different Languages.) I have a button bar with buttons for all the languages. There are a lot of instances of the custom component.
I want to click in a button of the languages bar and get ALL the instances switched to the same tab (the custom component contains the logic to change the tab). I can do it by adding the event listener for EACH INSTANCE of the custom component, so it calls an internal function that changes the tab. But it seems to be very coupled, isn't it? I wonder if it can be done in the master CLASS of the component, so it listen for events in its parent container, whichever it is. In my mind this code shoud work, but it doesn't (obviously ill'use a custom event to pass the new language value): this.parent.addEventListener("lang_change", this.change_tab); This way I can just drop an instance of the component, and see it working for itself.

If I don't specify width and height values for a TitleWindow, it will be resized to fit it's contents when I show it using PopUpManager. But there are moments when some components inside will be resized, like a ComboBox which dataProvider is loaded asynchronously, or another component which was not visible and I'd like to set it's includeInLayout to true. In those moments, I'd like to tell the TitleWindow to resize itself to fit window contents. I've tried calling invalidateSize() and invalidateDisplayList() with no success.

I am using PopupManager in FB4 to display a custom dialog.
popwin = new TitleWindow();
popwin.addElement(myCustomDialog);
PopUpManager.addPopUp(popwin,this,false);
PopUpManager.centerPopUp(popwin);
It's possible to drag the popped up TitleWindow and let go of it when its gray title bar lies outside the bounds of the Flex app rectangle,and then the popup cannot be grabbed again.It's also possible to drag the TitleWindow downwards so it becomes completely invisible below the bottom edge of the Flex app rectangle.When the Flex app bounds are less than the full browser window,and the user is working quickly, this chances of this happening increase.Is there a simple setting that will keep this from happening, or must the programmer intercept the behavior during the drag operation?

Ok so here is my XML slideshow Actionscript:
ActionScript Code:
stop();
var xmlRequest:URLRequest= new URLRequest("graphicImages.xml");
var xmlLoader:URLLoader = new URLLoader(xmlRequest);
[Code]....
So I figured that the coding of separate scenes would work independently of one another, but I guess I was dead wrong, because when I apply this to a different scene and change the XML path for a different set of images, I get all sorts of conflict errors when I test the entire movie. I have my flash film set up so that each link send the user to a different scene, which plays a unique intro for each, and then the slideshow appears on screen and the viewer can navigate the images.
Is there a work around for this? Or am I going to have to break my flash movie into separate movies? Or should I just add a suffix to all my vars and functions so that they are unique for each scene?

I have a problem with redrawing in flex 4. I have a spark titleWindow, and if i drag it faster, it looks like it's mask is one frame late after the component. it's easily visible with 1pixel thin border, because it becomes invisible even with slower movement.
You can try it here (what is not my page, but it's easier to show you here than uploading example):[URL]..
If you move in direction up, you see disappearing top border. in another directions it's not that sensitive as it has wide shadow, and it's not very visible on shadow. On my computer i see it on every spark TitleWindow i have found on google, although it's much less visible with less contrast skins, without borders or with shadows.

I want to be able to show a Spark TitleWindow container as a modal without having to construct it by code via AS3. I tried creating the TitleWindow before-hand manually by dragging and resizing it around and adding objects, etc then hiding it. Then on a button, I set the called function to the ones below:
public function doPopup():void {
testWindow.visible = true;
PopUpManager.addPopUp(testWindow, this, true);
}
Unfortunately, this only shows testWindow but not as a modal. I want it to be like this so that I can freely resize and design the layout of my TitleWindow and only have to call some function to show it as a modal one.

I'm a GIS Analyst that was moved to an Analyst Programmer position. This has been a hard transition for me as I don't have much of a programming background, but I was thrown into it. 'm working on a Flex app inside a jsp page. Essentially it is a grid 3x2 that has images and text. What I am trying to do is have more than one titleWindow reference in this page, so that when an image is clicked a titleWindow is opened. (If anyone has a better idea, especially if it has to do with a hover I am very open to that!) Currently I have it working for one image. However, when I try to add a second function it errors on me. "Error 1021: Duplicate function definition" Below is the entire code for the main page that calls up the titleWindow. The code below is what gives the Error 1021.

The customer I am working for wants to display popup in an AIR application (designed in Flex 4).I will therefore use TitleWindow and PopupManager for this (or NativeWindow could be an option too).
Pretty basic, I can handle this.
Trouble is, this customer would like this popup to be looking as a Fancybox, that is, with the close button, slightly out of the popup.

I have a modal Flex dialog and want to make the background not of the window itself, but the semitransparent modal indicator transparent. (Yes I tried to convince the client they don't want to do this, but apparently they really want to do it). Is this even possible?(prefer a solution using Flex 3's TitleWindow, but Spark/Flex 4 TitleWindow is acceptable)

I'm working with Flex 3.4 SDK. I need to change the default close button image from a TitleWindow. So what I'm doing is defining a CSS selector, like this:
TitleWindow {
close-button-skin: Embed('assets/close.png');
border-color: #FFFFFF;
corner-radius: 10;
closeButtonDisabledSkin: ClassReference(null);
closeButtonDownSkin: ClassReference(null);
closeButtonOverSkin: ClassReference(null);
closeButtonUpSkin: ClassReference(null);
}
The problem is: the result image is totally squeezed beyond recognition. Probably because the image dimensions are 55x10 pixels (much wider than the default closebutton square-like dimensions) and flex forces it to fit that size.

I'm using PopupManager to display (not modal) popups in Flex.How can I make the background of my TitleWindow popup completely transparent?Now it is semi-transparent.. see picture with semi-transparent background (i.e. I just want the label inside visible):

Maybe, instead of making it transparent I could try to reduce the padding, in order to make only the children visible ?

I have made a custom ActionScript mxml component, which is a spark TitleWindow with a text area, which header (titlebar) should display a green background if it finds the word 'success' in its text, or red, if it doesn't.
My problem is that I don't know where to access and modify this property, and the only turnaround I've found is binding the 'chromeColor' of the TitleWindow to depend on a boolean that will change depending on whether I find or not the word 'success'. And this does change the TitleBar background to the color I desire, however, it also changes the scrollbar color, for example, which is a bit nasty. The code for my class is the following:

In my application, I have a chart that I want to display in a TitleWindow when clicked on.
var win:TitleWindow = PopUpManager.createPopUp(this, TitleWindow, false) as TitleWindow;
win.addChild(myChart);
PopUpManager.bringToFront(win);
It does indeed place the chart in the titlewindow that shows up, but it removes the original chart from the parent. Then, when the titlewindow is closed, my chart is simply gone. I can't figure out how to clone the chart -- all the methods I've tried failed
Solution:
public var barChart:BarChart;
public function onClick(e:Object):void
{

I'm trying to open/close a TitleWindow using PopUpManager.addPopUp() and PopUpManager.removePopUp() while reusing the same TitleWindow instance. I noticed that the creationComplete() is only called once for TitleWindow even if I open it several times and was wondering what events I should listen to for the succeeding popup loads.
