Flex :: Changing View States On Application Resize?
Aug 6, 2009
I want to change the view states in my flex app when it resizes in the browser window.I have the swf embedded at 100% x 100%. So when the user resizes the window below a certain width, I want to switch to a different state. I tried adding an event listener like this, but it only fires the event when I resize the swf outside the browser, not inside. I used:
my problem is when i create a button in state 1 and click on it according to code it should make a group in another state named as expand. However according to my code it is still making group in current state 1.
I've just found out about View States in Flex (v3.0), but I am not really sure how widely this is used in real-world applications. Is it a good practice to use it? Are there any pitfalls such as maintainability for instance?
I am trying to use global application states to manage roles in my application. How can I use <properties.state> everywhere in my application if I declare it in my top level application?
I'm interested in finding out the best approach to this issue, it's not technically difficult but there must be an elegant solution. Basically i have a form that features mostly text inputs, i would like to change the style of the input boxes based on the current state. I can do this in the mxml on each input...
I have several custom components all of which are included in the parent application.When I try to change state from a custom component, I get an error saying "undefined state: state name". How do I change the state of the application from within a custom component ?
I am making a game. And this time trying to implement menu (-->tutorial) -> game-> scoreboard -> game over screens.
These screens themselves are quite different in terms of structure. So i am not sure if states is a 100% correct approach here (as I understand states are good for similar layouts) From the other hand many of them has back button to return to previous state, e.g. in tutorial I will have start game and back to menu buttons, etc.
I want to use Log4Fx to log button clicks from a state as i have a state based application with transitions.So on each button click I want to log which state was the user in while he clicked the button because the state change happens on a button click. Can someone suggest a code snippet?
I am working on an Adobe AIR Application. The size on Application window is 800X600 and is contains border container and border container contains many controls. What I want is to if user re-sizes the application then that container should also be re-sized according to scale. i.e If user maximizes or minimizes the window then that border container should also be maximized or minimized respectively.
I have an application that takes the user through a set of steps, configuring a product, say about 10+ screens. With options to go back, skip to a certain point etc. I need to fade between these steps, and also have language switches available at any point.
I was thinking of using an MVC style pattern, having a master view that accepts a 'next view' and fades it in, removing the old.
It feels bloated to have 10+ separate view classes, using similar components for this task, so was wondering what other approaches there are that I should look into? or one that is suited for this kind of application
I'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 application is contained in one of the rows of a html table, and that row is hidden as per one use case. Flex application is refreshed when visibility of the row is changed to visible. This results in lose of data that is already entered in the flex application. Is there any way to stop this behavior?
I want to load an initial component to be displayed in my flex app, depending on whether a value in the SharedObject is set (first launch). How do I accomplish that?
I've written a flex (mobile) application, that ended up bigger than I expected.
I'm pretty happy with all my classes and everything on my AS files. However, the view turned out really big, as I'm using MXML to layout my app.
I was thinking about creating external components I could call on my view to make it more readable, but am not sure what's the best way to do, or if doing so is the best way at all.[code]...
I've made a custom list itemRenderer with 2 buttons and a label. One button deletes the list entry (and thats not the problem) the second button would change the actual view.how I can change actual view within the itemrenderer ?
We have an AIR client which talks to a WAMP server. We store documents.One of the customer requirement is: they want to their website users to view the documents stored in the AIR application. It should be a read only access. The users will not have our air client installed on their machines. All they do is to check the customer's website.
I have the following problem of how to display another mxml file as main view of application For example, lets say I have main.mxml displaying as main window. When I click button I want to display another mxml file lets say newMain.mxml and close main.mxml
I have a flex 3 application that creates an Image from a canvas which the user draws on. I use the ImageSnapshot class to create the image
var imageSnap:ImageSnapshot=ImageSnapshot.captureImage(myCanvas); var imageByteArray:ByteArray=imageSnap.data as ByteArray;
I want the user to be able to print or save the image. I can use the following code to print the image but flex does not provide good control over printing across multiple pages
var printJob:FlexPrintJob=new FlexPrintJob(); printJob.start(); printJob.addObject(myCanvas, FlexPrintJobScaleType.SHOW_ALL);
I would like to display the image in a browser window so that the user could print it using the built in browser functionality or right click on the image and save it. Can this be done without requesting server side code to do it?
I have a quite different problem with resizing. I have a Flexbook component which uses the middle part of screen (center) with a html header menu and footer. The problem: The scaling works perfectly when we run in the local machine ( Flexbuilder). But when we deploy it to the server its like scaling never existed.. The requirement: when user maximizes the window or minimizes it, the Flexbook should be resized to fit the screen.
I have been working on a button class and ran into a little bit of a snag.
Here is the class I created: package { import flash.display.*; import flash.events.*;
[Code]....
Now while this class is working, I can't seem to figure out how to make it so when you click on one button it makes sure all the other buttons are sent back to the offState. I am using _mc's for my buttons. I think I need to put my buttons into an array and keep track of them at way, but I'm not sure about how to do that. Would I be able to get this effect to work in this .as file or would i need to write another one to control the buttons and where they are in there states(up/down/over).
I am trying to attach some of my actionscript class, inherited from Sprite, to my Flex application by attaching it to a UIComponent, then add UIComponent to a panel. However, the size of my Sprite class appears to be larger than the panel. So, I try to resize it using DisplayObject.scale property, but I need to know the size of my container. Since I try to make my code reusable, I figure that I should let my Sprite class handle the resize by getting it via its parent property (let's say, I can resize it by set
this.scaleX = this.parent.Width/this.width or something like this)
However, my Sprite class's parent, which is the UIComponent, has width/height of 0. So, my question is:
1) Is there any better way to resize DisplayObject class to fit its container when attached to Flex object?
2) If you know, why my UIComponent's size remain 0 and my DisplayObject still appears at its full size? Here's my code, using Flash Builder 4:
private var loader:Loader = new Loader(); private function testLoader():void { var urlRequest:URLRequest = new URLRequest("http://localhost/welcome.png");[code].......
I started with flex for mobile a few months ago, and I find it very interesting. I am now building a mobile app, but I don't know how to go further.I have a TabbedViewNavigatorApplication, with 3 ViewNavigators. In one of these ViewNavigator, I want to change the content, but not the whole view (e.g. I don't want the actionbar to slide). Please have a look at the attached image. How to do this?
I'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.
I have one .mxml file (the Application) with a ViewStack (with 4 views) and a ControlBard, obviously I can change the views with it, but what I want to do is: in view #1 I have an image which I want to convert to a "hyperlink", so when I click it I go to View #2, is this doable? Also I would like to pass somehow some data (like a String) to that View #2 (lets say the it's a user avatar I click so I want to go to the second view which will show me his profile, that's why I need his name/id).
My problem is that when I try to pass an object from the navigator.pushView(view, dataobject), I can't figure out how to access the dataobject from actionscript. I can access {dataobject.property} from MXML easily, but I want to set a variable in the new view to the passed dataobjects property.
I have two viewstacks one for Main menu and another one for submenu. I want to show viewstack page infomation at the time only one viewstacks . Another one hide . if i click submenu viewstack then Mainmenu viewstack will be hide . [code]...
I am trying to find a stand alone flash player/controller to play flash movies on my own computer (windows xp) ideally it would have the usual back stop forward controllers etc and I would if possible be able to change the veiw pane background colour.
