Flex :: Components - Executing A Function On Another View?
Jun 5, 2011
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'm developing a Flex/AIR application that's growing big, and some of the components need to be seen from different points of view (i.e Admin, Staff, User, Guest). I've seen myself placing code in those components to handle what the user can and can't see. But it's becoming unmanageable as the code and the roles grow bigger. I was wondering what's the best way to implement multiple views inside the components while keeping them as reusable as possible.
What I'm doing right now:
<mx:HBox width="100%" horizontalAlign="right" visible="{_view == TS_VIEW || _view == PRJ_VIEW}"
includeInLayout="{_view == TS_VIEW || _view == PRJ_VIEW}">
<mx:Button label="Agregar" click="button1_clickHandler(event)"
enabled="{_state != ADDING_STATE && !_loading && _canAdd}"/>
</mx:HBox>

I have a main.mxml, child.mxml and headermenu.mxml. I click a button on the headermenu that dispatches an event up to the main.mxml which then executes a method in child.mxml. I know this works because I put an AlertDialog in the function I'm calling inside of the child.mxml. The child.mxml contains a drawingArea object that has an erase(). When I call this directly from child.xml it executes, however if I put drawingArea.erase() inside of the function being called by child's parent (main.mxml) nothing happens.[code]...

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 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 am using a List component inside an itemRenderer. The main user interaction involves dragging an item from the List in one renderer and dropping it in another. My problem: When the data object is updated I want the Lists' height to be modified according to the number of objects in the dataprovider(dp), which is passed to the List from the data object. Now I have tried to invalidate the display of the List, refresh its dp and have tried putting this line assets.length > 0 ? assetList.percentHeight = 100 : assetList.height = 10; in other event handlers, such as dragdrop handlers, collection event handlers for the dp etc. I have also tried refreshing the dp for the List component that is using this renderer. The view does eventually get updated but only if I resize the list, or use the scroller or when I begin dragging a new List item but never after the drop.

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.

Here's a damn useful snippet:
ActionScript Code:
/**
* Use in place of trace(). Calling function will be logged automatically.
* */
[Code]....
Put that code in a utility class, and then from any function or method in your app, call myClass.reportStatus("Something happened"); and you will be rewarded with something like this:
060510 15:48:11com.foo.commands:oSomethingCommand/execute()Something happened

I have a function and a movieclip prototype. When the prototype applies an onEnterFrame to an mc, it repeatedly calls the function (hitTests for all other mcs). Besides this, it also eases the mc to a new point. However, when the mc have reached this point, the function handling the hitTests stops being called
PHP Code:
//Prototype....MovieClip.prototype.moveSprite function(speed, spriteType) // Generate random coordinates var tarX = Math.round(Math.random()*(400-

A function has to "run"(execute) inside the onEnterFrame event method but the function does not seem to run when called.
Example:
_root.onEnterFrame()=function(){
if(something==true){

how could I find out how long is some function executing?is this number, however small, always consistent for the same function or there may be differences (taking in consideration that only one function is running at each moment)?

The function should trace "carn" over and over and over, but instead, it traces "carn" over and over until the prototype picks a new point to ease to.

I set a function for
this.onEnterFrame = function(){
code;
}
but later I want this onEnterFrame to stop functioning to conserve on processor resources. setInterval isn't too good of an option from the way I have things set up, so right now I just set it to a new function with a trace action which overwrites the old one.Is there a command to simply just clear or break the function from executing?

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.

(Using Flash Pro 8). Currently, I just need to execute a simple show/hide function that is controlled with a key. Currently, I have a circle movieclip with this coding attached to it:
Actionscript Code:
onClipEvent(keyDown){ if (Key.isDown(Key.RIGHT)) _root.circle._visible = true;}onClipEvent(keyDown){ if (Key.isDown(Key.RIGHT)) _root.circle._visible = false;}
And on the first frame of the timeline, I have this code ( so that it is visible = false to begin with ):
Actionscript Code:
_root.circle._visible = false;
Now, my problem is that when pressing the RIGHT key on the keyboard, it reveals the circle, but when it is pressed again, I want it to hide the circle again. Obviously there's a conflict between false and visible, but I don't yet know how to tell flash to make the distinction that the RIGHT key has already been hit once. Is there some kind of 'listener' or something?

I'm making this game with Adobe Flash and I have this level where you need to stop a bomb from exploding, but when you stopped it and go to the next frame the bomb is still running and you still go to the game over screen when the countdown reaches 0. For the countdown I use the following ActionScript:
[Code]...
(Frame 4 is my game over screen) I also add with the dynamic text the word ''count'' next to Var: So is there a way to make it stop running on the next frame? Also am I willing to use a different ActionScript for a countdown if somebody knows a better one.

I have this movieClip "Container" and within it on two different frames I have two movieClip/buttons, "pause_btn" and "play_btn", respectively. I would like to call a function on the main timeline on frame two of "Container" where "play_btn" is located.
I think I'm getting close but really have no idea. I know about the visible property and have been considering that, but isn't there a way to call a parent function from within a child movie clip? The code looks like this.

I'm making a game and the main functions are close to finishing. But I'm having problems with my start screen. I'm working entirely in Flash Builder.My users should be able to click a button to start the game. Right now I don't have a functioning start screen yet, but initially the game started immediately with Game.as. But I now decided I want a start screen. So I made a new class file with the graphics and buttons for the start screen in the constructor function, and I added a Mouse click event listener to the button.The game itself is in Game.as, that runs perfectly.In the function for the mouse click event I added:
Code:
removeChild(startscherm);
var startgame:Game = new Game;

I have a pause function that fires when the first frame of my swf loads.
PHP Code:
Welcome transition
function pauseMC(sec) {
var i = sec - 1;
var MyPause = setInterval(function () {
if (i == 0) {
clearInterval(MyPause);
[Code] .....
However, if the user navigates away from this "Welcome" section, the actions following the "pause" still fire. I need to find a way to stop the pause function prior to the actions executing. Below is the function used to trigger the navigation events and where I should be executing the action to stop by pauseMC.
PHP Code:
function moveLeft () {
var t = this;
this.opened = true;
//this._x = _root.navWidth * this.index;
