In 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. Is there a way to tell Flex to hide an element when it doens't fit? I know it is possible by using states and test the width of the screen but I hope there is another way..
View 2 RepliesI am having a problem with my drop traget. I have the ability to drop and duplicate multiple objects on a stage. I have a clip set up (canvas) which is used for if someone drops objects onto this it duplicates the dragged clip.
However the problem I am having is that if someone tries to drop an element on top of an already drop/duplicated element, it wont duplicate the new clip. Its like it thinks that the dragged clip is not over the canvas.
i have TileList from which i'm dragging some stuff(image) to Tree (something like dragging sounds into playlist in iTunes), but when i can drop this stuff, i see only underline, this mean i can drop it only under or above some leaf-element in that Tree. How can i force it to hide this black underline and highlight leaf-element to which i wanna drop my stuff.
View 1 RepliesI have a dropdown combo box that contains numbers 1 to 10. Normally it will show '1' when the application starts, but how do I set it in AS3 to show '3' instead?
View 3 RepliesI 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().

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 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.
How do I put things above an mx:HTML element? No matter where I place the code it's always under the <mx:HTML> element.
Example:

<mx:Label x="150" y="50" color="#ffffff" text="CAN YOU SEE ME?"/>

<mx:Label x="150" y="50" color="#ffffff" text="CAN YOU SEE ME?"/>

I'm trying to implement a dragging system which can only be described as similar to dragging the map on Google Maps. I can set up dragging easily in Flex, but unfortunately the standard model of dragging i.e. dragging an element proxy and dropping it in another element is not what I'm after.
Is there anything built into flex where the actual element rather than a proxy can be repositioned in a different place within the same parent? Or will I have to hand code something using mouse events as you would if implementing a solution in JavaScript?

I have three datagrids inside VBox container. Since I don't want scrollbar in my flex widget i am increasing the height of SWF through javascript, which increases with each addition of row in my datagrid. My query is how can I get the exact height of my VBox which is the parent element of datagrid. I am not able to get the height of VBox. I have tried to use measuredHeight,height with no success.

Say I start at a leaf node, and I traverse up the tree by using .parent(). I need an exit condition once it hits root. At the moment, I'm using parent.@name != "root", where name is just an attribute, but shouldn't I be able to check the type of element as well? How? Also, is there another way to end the traversal in as3?

I have a list component with a (row oriented) tile layout in a group that sits in the main Application. I want the list to be centred vertically when there are not enough items in to fill the application window height, so verticalCenter="0". However, when there are more items than can fit vertically on screen, the list expands beyond the application window height and the scrollbar doesn't kick in. I can remedy this if setting the list height to 100%, but that means it's not vertically centred when it contains less items. The ideal solution would be maxHeight="100%", but of course maxHeight doesn't work with percentages. How would I go about achieving this behaviour?
