Where am i going wrong? It seems to be the most basic example but i'm stuck. PS: I'm using FLEX 4, Flash Player 10, and Flash Builder 4
I need to run some code when a panel is destroyed. The code is simple, I have some Background tasks while it is opened, but need to stop them when closed.
I have a Close button for the panel, and I stop the BG Tasks when the user wants to close the panel, the problem is that they have access to a top menu bar too and can jump to another application module/part throught it, so, the user can exit the panel (when exiting, the panel is automatically destroyed) but the panel close event code is not executed because the close button was not pressed.
One solution could be to inherit from panel and add a post step method that is called when swapping modules, etc... So, if the user wants to move to another place through the menu bar, my system will first call sometihng like PreEnd() method on the panel and everything will be solved. But, is there any event that I could catch from the panel when it is destroyed to accomplish this? I have been checking the documentation but couldn't find anything useful to achieve what I explain.
how to build and compile flex 3 projects in visual studio? I prefer that environment to Flex Builder 3.
View 2 RepliesI have a sprite element that i need flipped around 360 degrees, in it's position. I am looking to flip it forward, (similar to a dial in the casino machine, spins on the z axis).I would like it to look as if it was flipping forward, and then back to it's spot. The rotation would have to be on the z axis. I would prefer not to use the Enter_Frame event.
_testSprite = new Sprite();
_testSprite.graphics.beginFill(0xFF);
testSprite.graphics.moveTo(0, 0);

Ive been trying to get flex popups to open under some of my visual elements.
View 1 RepliesIs there not an event that occurs only when there has been some sort of visual change to an object. So for example if it were a video or animated object it would be firing as often as EnterFrame. However, if it were some sort of input control just sitting there doing nothing visually, then the event wouldn't fire until the visual state changed as a result of some sort of user input for example.

View 2 RepliesI would like to avoid the tags overlapping each other in this small Flex project: I've this small FLEX project: [URL]..
The items are LinkButtons. How can I check if they are colliding or not ?
I'm playing around with code like this:
<s:Button id="test" label="test" transformX="{Math.floor(test.width/2)}" rotationY="20" x="20" y="20" />
The button is rotated on the Y axis and the rotate pivot is in the middle of the button.
This will create a button that looks something like this[code]...
I put together a sample to show off the various approaches for calculating this that people are suggesting. The source code is also available. Nothing is quite working like I'd expect. For example, turn the rotationSlider to 85. The button is effectively invisible, yet all approaches are still giving it height and width.
Do you know how if you drag an <mx:Label> or <s:Label> component into your Flex project, when you go to design mode you get this panel on the right to set its properties like text etc.
I have a custom component that I can call with actionscript, or with mxml like this:
<comps:TheComp field1="OK" field2="Yes" />
The component takes this input and uses it for its internal operation
[Code]...
When I go to design mode, I can see the component under custom components, I can drag it to the stage and see it, but can't set its values field1 and field visually on the right like a normal <s:Label> or <mx:Label> would have. how I can add that? Do I need to make it inherit something or anything else
I can't seem to figure out how to accomplish a fairly simple task: I have a simple graphic and I'd like to apply an "orbiting" effect to it - so that the graphic moves in a circle around an arbitrary point (without rotating around its own center).[code]...
View 1 RepliesI'm trying to test a custom Flex 4 skinnable component, using the FlexUnit UIImpersonator class. If I run my tests from a FlashBuilder Spark only project everything works fine. If I try to test from a project with the mx component set on the classpath I get a "getElementIndex not available in non Flex 4 projects" error.Can I unit test spark components in FlexUnits visual test environment while still having the mx component set on the classpath?
UIImpersonator delegates it's method calls to a "testEnvironment".The implementation used for this "testEnvironment" is decided by the VisualTest EnvironmentBuilder class and the FlexEnvironmentBuilder class. If the FlexEnvironmentBuilder class can find the "mx.core.Container" on the classpath it returns a MX environment, else a Spark environment. Only the spark environment has valid implementations for Flex 4 relevant method calls on the UIImpersonator - like the addElement method.
I know that there is no such function as getElementByName in Flex but I also now that you can do this["object_id"] to get the element of the application u're in.What about getting an element inside another element?I've tried making element["id"] ? But in my try-catch it always runs the "catch" part..how do I get an element inside another element just having it's id in dynamically created string form?
View 2 RepliesI have flash where there is a link for song download. And, at the bottom of the flash I've a count, loaded thorugh flash vars which should increment everytime donload button is hit. Please let me know what approach should i take to do that. can i call a Java method on donload button which will insert a row in the table and and then get the count and render it to the count variable in my flash?
May be this extremely confusing. Here is a very similar example on how it is done. This is actually very similar to what i want to do. [URL] on this link there is count below which increments you hit the download button.
I've built a rather robust tooltip class recently that attaches and draws a single tooltip sprite to the root, then uses MOUSE_OVER to detect when it is over a tooltippable object, and shows the appropriate tooltip text. At the moment, I'm ensuring that any elements in my application which wants to take advantage of showing tooltips implement the ITooltippable interface, and expose a public getter, get tooltip().
[Code]...
Basically I have 14 text boxes, each box draws its content from an external txt file. Next to each text box is a button. I want the button to be either visible=true or visible=false depending on weather or not the text box has content or is "undefined" Here is what I have so far, and it's not working:[code] I would like a FOR loop to just run through the variables and check to see if any of them are undefined. if it is, then make the correct send button invisible.

I've got a spark list that gets dynamically filled.So far the new items appear at the bottom of the list. What I'd like to do is to add them at the top.The items in the list have a unique ID so some kind of sorting mechanism would probably do the trick as the new items have a greater ID than the old ones.What I'd like to avoid is some complex method behind this as I'm working on a mobile platform and the list can get quite big so I need this to be as efficient as possible.The list's data provider is an ArrayList that gets updated using binding.
View 1 RepliesIn Flex Mobile I have a few buttons in the action bar. On devices with very small screen (such as the HTC Wildfire) not all buttons can be shown.

View 1 RepliesI have a simple list in Flex that is populated every N seconds by a dataprovider. My goal is to avoid scrolling the list after the dataprovider has been changed.
So, before I populate the list, I save the selectedIndex, and once the dataProvider is filled, I call:
list.selectedIndex = index;
list.scrollToIndex(index);
Trouble is that this moves the selected item of the list to the top. The solution would be to get the index of the first element displayed in the list: but I have no idea on how to get that.
