I'm trying to implement a binding between some custom-built models and just beginning to dabble with the whole mx.binding.* collection. I tried this simple, stripped down example, but can't get the binding working correctly. Can somebody tell me where I'm going wrong?
[Code]...
I have a bindable getter in a component which informs me when a [hidden] timer is running. I also have a context menu which, if this timer is running, should disable one of the menu items.Is it possible to create a ChangeWatcher which watches for the negative condition of a bindable property/getter and changes the enabled property of the menu item?Class B:[code]In the code above, I have the inverse case: when isPlaying() is true, the menu item is enabled; I want it to only be enabled when the condition is false.[code]
View 1 RepliesI am having problems with a ChangeWatcher.Everything seems to be set up correctly.The canWatch method returns true, the isWatching method returns true and if I query the return value of the getValue method I get the correct information, including changes. But for some reason the handler function just doesn't fire.
View 1 RepliesI am using flex SDK 3.5. I have model.as and in it i have an ArrayCollection (name it arr_mod) which is Bindable.
From my mxml i link to this arr_mod in three places:
1) in DataGrid i set dataprovider={arr_mode} ...
2) in Button i add new item to the arr_mod this way: mx:Button .. click = "{arr_mod.addItem(new Item)}"
3) in textBox i want to add mx:TextBox text="{mySpecialCounterFunc(arr_mod)}"
note that in the Script of mxml arr_mod is Bindable as well as in the class definition in model.as
The problem is, that when clicking on button, mySpecialCounterFunc is not called! it should be called, since i use {} and this should listen to changes in arr_mod (a change that was made in the button should cause a new item to be added.. and than the listener to respond). While The DataGrid is updated correctly! By the way, if i change arr_mod to simple String or Int it works.. i.e. mySpecialCounterFunc is called Why??
Does data binding work with the UITextField? Unfortunately, I'm getting the variable instead of the bound data.
[Bindable]
public var myString:String;
in a function, where tf is a UITextField:
myString = "blah blah blah";
blah blah...
tf.text="{myString}";
It's giving me {myString} instead of its data.
The Flex application below generates the compiler warning: Data binding will not be able to detect assignments to 'dp'. This seems correct since the variable 'dp' is not a bindable property (there is no [Bindable] metadata tag). I have added a button which appends items to the back of 'dp' when it is clicked. Although the compiler warns me that I will not see changes to 'dp', the list shows the new item every time the button is clicked! I do not understand why I can see new items appear in the list. Can someone explain why this still works although 'dp' is not bindable?

So I had a requirement to add an undo function to my app and I discovered this nifty ChangeWatcher class, but it's not doing exactly what I want and I'm hoping someone knows how.ChangeWatcher seems to monitor assignments to the variable reference. So when I say:
myXML = <xml/>
it fires off it's function just fine and dandy, but when I say: myXML.appendChild(thisOtherXMLVar)
I get nothing, even though the variable changes the reference doesn't so ChangeWatcher doesn't fire off the function.how to get ChangeWatcher to pick up on all changes to a variable?
I have a Number variable, named isConflict, whose value is passed in from a parent. I would like to put a ChangeWatcher on this item so that a function named changeBGColor will run whenever the value is changed. Within my creationComplete function of init, i have the following:
var isConflictWatch:ChangeWatcher = BindingUtils.bindSetter(changeBGColor, this, "isConflictChain");
On creation complete my parent component executes an "init" function which simply sets public bindable variables in child components. I'd like the child components to watch these variables and upon being set use them. However, for some reason the ChangeWatcher is not firing with the change of the variable. Below is my code;
Parent Component
private function init():void
{
userInfo.user = new User("Tom");

In this code I'm creating a new window when I click the button. In the new window are TextInput and DropDownList components. When the new window opens, clicking the DropDownList does nothing - you have to click it a second time round to get it to open. However, click into the TextInput field first and then try opening the DropDownList works no problem.
Below is the code, or download the FXP file here.

When I run the resultant flash file on my remote server, it works 100% and test.text gets populated to "successful". However, when I run it on localhost test.text is still blank. If I check my network monitor in Flex, the httpservice was successful, so crossdomain.xml seems to be set right ...what am I doing wrong? I've been spinning my wheels for some time w/out a clue.
Why Flash Firebug doesn't work with flex 4.5?
UPDATE:
I have Flex 4.5 and in the main application, in the script tag I write:
import ominds.Firebug;
I use flash player WIN 10,1,85,3 Debug enabled. I export swf as 10.1.85 version.
And when I open the flashFirebug I get this: "No SWF files with the O-Minds package found, you should import the O-Minds package into your flash files. For more information visit: o-minds.com/products/flashfirebug"
recently I got a jagged image problem when scaling. I set my image components smoothBitmapContent true, and it works properly the first time, but if I reset the source, the images return jagged. It seems like the smoothBitmapContent property has been changed to false, but it doesn't work even if I set it to true in run time.Here's is my code:
<custom1:SmoothImage id="MJCard_3_36" x="286.5" y="56.65" scaleX="0.66" scaleY="0.83" smoothBitmapContent="true"/>
MJCard_3_36.source = seabedPicArr[index1-1][index2-1][index3-1];
I simply use a custom Image-extended class and switch smoothBitmapContent on, and I set the image's source in run time.

I have a TextArea that shows the conversation from selected chat room. For valueCommit event I use: verticalScrollPosition = maxVerticalScrollPosition; And it works fine scrolling text to the bottom. However in one case it doesn't work as expected. There's verylittle text, so TextArea has no scrollbar and then I put a lot of text and a scrollbar is necessary. The text is scrolled almost to the bottom (still a few lines need to be scrolled down). I am pretty sure it gets maxVerticalScrollPosition as if there was no scrollbar. So the question is how can I wait with updating verticalScrollPosition with respect to TextArea's new size (that is now with a scrollbar). I tried calling validateSize and other methods that start with 'validate' but unfortunately with no luck. I also tried the old trick of putting caret at the end of text. So the TextArea's scrollbar makes a difference when getting maxVerticalScrollPosition and I need to update verticalScrollPosition once all measurements are done. I forgot to mention. I use htmlText.

I have a CustomTextInput component based on TextInput (Spark) component. The instance of this class is placed on a popup window (TitleWindow). How can I capture the popup move (dragging the title) event inside CustomTextInput implementation?
MoveEvent.MOVE event of the CustomTextInput itself doesn't work. Of course, I can't access the parent popup window inside the component implementation, because it's a common component that can be used not only on the popup windows.
I wonder is anyone can look at this code and tell me why calling the removeSelectedChild works when called from the same document, but returns the following error when called from the child document/component.

View 1 Repliesi'm creating a reusable flex tree component. And i would like to stick in the itemclick funtion. So that when a user clicks anywhere on one of the tree's Branches. the branch expands.My problem is that i don't know how i can get the listener function to fire.What i would like to do is create the tree completely in as3. (no mxml). Normaly i set the itemClick on tree in the mxml. but i want to do this in as3. My component has alot more functions in it but i have deleted them so that it becomes easier to read. I Thought if i override the createChilderen function and add the eventlistener in there, that i would work. But no luck.

If I set the properties of "buttonMode" and "useHandCursor" to true in DataGrid, it does not work as I expect. Only if I move the cursor to the edge between two rows, the hand cursor displayes.
What I expect is that no matter where the cursor is moved, it should always show hand cursor.

We use the FileReference component to upload file in Flex. But if the application is deployed within an environment having NTLM authentication (Windows Integrated Authentication), the upload capability will not work, and each time a message box will be popup asking the user to input credentials.I've queried some resource from internet and it seems this is a bug of FileReference component.
