Actionscript :: Flex - Run A Function When View State Is Change
Apr 12, 2012
I am learning Flex and trying to make a simple RPG to practice. I am using view states to change between screens. right now I have a HomeView.mxml which displays my character information, InventoryView.mxml which shows my inventory items, and EquipmentView.mxml which shows the equipped items. They each have their respective view states.
in my main mxml file, i create a global variable for the character and an ArrayCollection of items in the game. it creates 2 labels in mxml for Inventory and Equipment and when i click on the label it calls a click handler which sets currentState="EquipmentView" or "InventoryView" This works and the state changes and the respective views are shown properly. My problem is in my EquipmentView state. When i enter the state the first time, it has a creationComplete function which displays images for my equipment and sets a click handler. when i click the item, it "unequips" it and removes it from the equipment list and removes the image. this also works fine, but when I go to my inventory view and "equip" an item and return to the EquipmentView, the image does not show. I have a label which counts the length of my equipmentList variable and that is accurate when i switch views, but i cant get the image to display again. Is there a way to call my displayEquippedItems() function (which is originally called on creationComplete) when the view is changed?
I have one list, which the item render it`s like this:link. But now I need to enable or disable the button delete depends the view state which my List is inside. This is my view(which contains the list):
I have decided to go the route of using ViewNavigator and having one view with 3 states. Each state is a "page". It runs just fine on the desktop but when compiled for mobile, the transitions between the pages is really laggy, even for the Samsung Galaxy S. The phone has the 2.7 runtime and I recompiled my application with ADT 2.7, still no performance increase.
I have also tried cacheAsBitmapMatrix on all 3 pages, which are all contained in a VBox and that hasn't shown any significant performance bumps. All I'm changing is the y component of the VBox for each transition.
EDIT: I have done some more research and I am now to the point where I have hardware acceleration turned on and cacheAsBitmap = true and cacheAsBitmapMatrix = new Matrix(). I am also using Stats.as to see the FPS. I notice on my state changes I go from 25 FPS to 2 and then it goes back up again.
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).
In Flex Builder 3, I am trying to access the main applications view state from within a component.On initialize I show the Loginpage-component. When I click the login button I want to hide the loginpage and show my "controlpanel" page, which also is a component.I try with this, and also placing this function in the main application.[code]
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 got a whole bunch of data being displayed in different Labels, now I'm adding an edit state. I'd like all the labels to "transform" into TextInputs. I was just wondering if it possible to uses states to change
I have a button with a click event of "currentState='someState'". Is there a way to tell component to do some function like for example "Function()" when the state changes to "someState"? So execute a function when the state is changed.
I currently use: Flexglobals.toplevelapplication.component1.compnent2.currentState = 'something';is there a better way of doing do? Can I bind the state of a components to variable in my model?
I can do this: <s:Button id="Btn" enabled.State1="false" /> But the following code is giving me an error. private function enableDisable():void{ Btn.enabled.State1="false"; //Error: Access of undefined property State1 } How to code enabled.State1 in ActionScript?
I am trying to use a combobox in flex with an array to change to a canvas in a view stack. Can I do this with some custom action script? The UI I am designing could really benefit form this.
I want to implement this script: [URL]...that is doing this "magic [URL]
...but I want to tweak it a little on InfoWindowTabbedComponent. To be more precisely I`m trying to insert links in that tabs, and when you click one the state will change.
You can see my custom InfoWindowTabbedComponent at the end of the post As you can see, right now I have 2 functions that open url`s.
What I`m trying to do is to change this:
var adobeURL:URLRequest = new URLRequest("http://www.microsoft.com" ); navigateToURL(adobeURL, "_self");
For my custom components, when they go from enabled to disabled or disabled to enabled, I want to trigger a custom event. I can't find any related events in the livedocs.
I don't know if this is too difficult or too easy. My custom component is trying to listen to the main application's state changes using StateChangeEvent.CURRENT_STATE_CHANGE, but it's reporting its own state changes.
I've found a very annoying problem with the itemRenderers in a DataGroup in flex 4, when I mouseout of the itemRenderer is returns to its default state. Here's an example:
When the user clicks on the button the VGroup is collapsed as expected, but then if a user moves their mouse out of the item renderer it then collapses, i.e. returns to its default state.
I have three columns and the default visible state of last column is false.My problem is how can I change the visible state of the certain cell while the mouse over any part of the row
I have a custom component ExpandCollapseMenu that extends SkinnableContainer.This component can have state "normal" or "expanded".Inside this component I have buttons, with different skin based on ExpandCollapseMenu's state.This works fine when defining the buttons inside ExpandCollapsMenu's skin class:
I am learning Flex and have an image I would like to changed on mouseover, and switch to another state on click.I do not want to use any of the buttons available in Flex.Does anyone know th code to achiev what I want?
I have a headerbar.mxml that is displayed when user swipes_down in my app. The headerbar.mxml contains a button component I want to run an erase() in the main application window. The main application is a drawing app that contains an erase(). I just don't know how to call a function from another mxml view file. I thought it would be something like
click="{mainwindow.drawPanel.erase()}"; EDIT: protected function onColorChange(event:List):void{
I have been working on a Flex Mobile application using Flash Builder 4.6. I have 2 mxml 'views' in my project. In one mxml file, i have a function that grabs xml data. In my other mxml file, I have a refresh button that when depressed is suppsosed to call the function in the first mxml file in order to once again grab the xml data. I dont know how to call that function from outside the mxml file it is housed in. [UPDATE #2]* I thought I should share some more details about my issue.
It is a reddit client mobile app. It fetches the feeds, etc. In my main view called RedditReaderHomeView.mxml, I am using a splitViewNavigator spark component to house two other views like so:
I am a beginner developer in Flex, and I have been using viewstates lately. I had a couple of custom popup titlewindow components that are initialized using[code]...
They both contain view states already, and are very similar so I wanted to combione them into one popup titlewindow and change view state on initialisation of the popup to either the Create version of the popup or the Update.
I thought I was being smart haha, but I realized soon after refactoring my code that, I as far as I know I can't pass parameters to the popup to indicate which state I want, if it is created using the PopUpManager.
Does anyone know how to pass parameters to the PopupManager, or create the ContentCreate component(TitleWindow) in mxml or code so I can specify the view state?
I want to use Adobe mxml to create a swf. However, the mxml gets compiled to swf itself and is not available after creating the swf. I want to add states with UI components without compiling it every-time.
I have a component with 2 states and I have added transitions for switching between the states, where 2 Move affects are applied to 2 different objects. This all works fine, however, after the transition from the first state to the second has completed the second state doesn not render correctly. It contains a TextInput control which is not visible, and a Button with a custom skin that is only sometimes visible and vanishes if you click on it. I have tried called invalidateDisplayList() and validateNow() after loading the second state but that has done nothing. I also have a VBox with a cornerRadius property set, strangely this does not seem to apply anymore and the corners are square, where they displayed correctly before I added the transition in.Here is the code for my states and their transitions:
<!-- different states of this component --> <mx:states> <s:State name="useForFree"[code].....
where the variables being set as masks are UIComponent instances where I have used their graphics property to draw a rectangle.
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.
It's my understanding that view states can be useful when switching the layout of design elements. Such as, a loading page as one state and the main application design in another state. Is this the correct use of them? Additionally, I have a label in State1 and I cannot figure out how to access that label via actionscript. labelID.text = "New Text"; is not working.
I'm using Flex 4.5 and trying to take advantage of the new state groups feature. I have two States (call them readType1 and readType2) that both belong to the same stateGroup (call it readOnly). There are several places where I'd like to do something based on the current state, and it would be the same thing for the two read states. [code]...
