Does any such control exist out of the box for Flex? I see people say things like "EPUB is just a zip file of XML and HTML files, so it shouldn't be too hard"... yeah, I get that... but if such a control exists, I wouldn't have to write it.

Its just shows how to unzip the epub file, either local or in web.[URL].. how can I display it in both web and air. I Just succeeded in displaying the PDF in web and mobile, but not the epub. Need a swc for displaying epub.
View 1 RepliesI'm wondering if there is an encoding like UTF8/16 that can account for characters that are bold, italic, underlined, and super/sub-scripted? If not, is it under consideration by the powers that be? Reason for the question is that I have a large excel file where many cells contain rtf text such as italics, bold, superscript; and I need to access the information on a row-by-row basis. I know I can save the file in html or xml, but I would like to import the data into MySQL - keeping the formatting - and then being able to access the data a row at a time.
I've considered using Markdown or Textile, but that means a whole lot of time changing each cell - we're talking about 5,000 records. Also, I want to continue to use Flex and I'm not sure if Flex can display html formatted text in their text controls because of their their text engine...
I'm new to flex, actually I'm reading a simple tutorial about Flex 4 (I'm using flash builder 4.5) this is the tutorial.I added a RichEditableText and then I should specify the property selectionColor, but when I add it to the source code, the IDE give me an error like this property do not exist.
<s:RichEditableText x="179" y="95" text="hello" fontSize="24" fontWeight="bold" color="#E52222" selectionColor="#000000" />
I want to show some data from an xml file inside a datagrid, so I do this:
<mx:AdvancedDataGrid id="dgDomains" dataProvider="{new XMLListCollection(xmlDomains..domain(deleted.toString() != '1'))}"

I am currently developing a dynamic LineChart in FLEX 4.I am implementing a Tree control next to my LineChart, which will filter the LineChart dataprovider and lineseries. The tree control has several branches and ultimately 5 children (leaf nodes) at the bottom of the last branch.I need the leaf node/children to be displayed as checkboxes inside the tree control.As I understand,this will require overrides in the TreeItemRenderer class.This is where I am a little confused on how to implement that.Currently I can distinguish between leaf and branches using this code, in my main MXML component.I added this because it may be helpful to some beginning FLEXdevelopers, such as myself, who cannot easily find this functionality documented well:
private function treeClick(e:ListEvent):void {
_selectedItem = Tree(e.currentTarget).selectedItem;
if(mainTree.dataDescriptor.isBranch(_selectedItem)) {[code].....
I am looking at the TreeItemRenderer override class from the following example here: In the example, they override the "createChildden" super function to add checkboxes to the tree control.My question is, can I override the createChildren function directly in my MXML component, and not have to use an entire class file to override this functionality? Must I re-invent the wheel to do this?Also, how can I distinguish that my treeItem is a leaf node and not a parent, in the override function? I only want to add checkboxes to the leaf nodes, how can I differentiate? The following example adds checkboxes to all branches and leaf nodes, but I want to add checkboxes only to leaf node/children. How would you approach that?
override protected function createChildren( ): void
{
super.createChildren( );[code]............
Here is my tree tag:
<mx:Tree id="mainTree" dataProvider="{treeData}" itemRenderer="TreeCheckBoxItemRenderer" labelField="@label" showRoot="false" width="100%" height="100%" itemClick="treeClick(event)" />
I am trying to manipulate (move up and down, enable/disable and launch a form) child controls inside a panel control. However I am unable to get the id of the child control on which the click event occurs. To illustrate, I am trying to create similar functionality as is available. I am trying to create the up-down buttons that you see in the image at http:[url].......
View 2 RepliesI have a flex application and have embedded a flash (SWF) file into it using <mx:SWFLoader>. There is an "Exit" button on the Flash file. I want to be able to handle the button click event on the flex application.
So when that button in the flash file is clicked, I want to perform an action in the parent flex application.
Internally Flash obviously keeps a list of the primitives drawn using Graphics so I wondered if you have many such primitives in a Sprite, can you re-position/remove/alter individual items rather than clear and re-draw everything? Or is this deeper into the bowels of Flash than you're allowed (or recommended) to go?

View 2 RepliesI am currently working on a Flash socket client for a pre-existing service/standard. The service uses TCP flow control to throttle itself and the Flash socket is reading in everything as fast as it can despite not being able to process it as fast as it's being taken in. This causes the bytesAvailable on the socket to keep increasing and the server never knows that the client has fallen behind.In short, is there any way to limit the size of bytesAvailable for a Flash Socket object or throttle it in some other way?
View 2 RepliesI need to render a large number of hextiles on a canvas. I would like to make this such that I render only the tiles that are visible to the user and load additional hextiles as the user scrolls (using drag or arrow keys or a pan control). I've the basic idea in my head but I'm looking in coming up with a more robust solution that will scale well. What I have in mind and can do right now: a. identify the tiles that need to be loaded to the screen and get the data for rendering them from the serverb. when the user drags, figure out the new set of tiles that need to be loaded and get the data and reload the whole screen again.
This works but it doesn't give the feeling of scrolling - it essentially suddenly repositions everything. Ideally, I would like to get the feeling of google maps when scrolling this. I've been playing with loading some tiles on the side off the map and only scrolling the underlying canvas when dragging but this doesn't work too well because the canvas runs out... it would be really neat if I had a canvas that behaved like a circular buffer so scrolling in any direction only kept a certain number of tiles in memory and I can continuously scroll in all directions.

When setting up a source control repository for a Flex Builder workspace, what do you consider to be worth checking in? Do you exclude the workspace .metadata folder but keep the .project and other project specific files? Keep both? Throw away both? Is there a guideline you use to decide which is worth holding onto or do you do it out of practical experience?

View 1 RepliesI am using the flex flv player component and i want to be able to skip 5 seconds forward and backwards , at the moment from what i understand from the documents it is not acurate because the movie can only skip to keyframes sometimes making the skip 6 or 7 seconds. the same goes to cue points which the flv might miss the actual point if there is no keyframe there/ my question is there any other way to use the player in a more accurate manner ? since i see on the web players that can do these skipps
View 2 RepliesImagine you have a large number of video files stored on a server, and a Flex app which lets users play those videos they have access to. How can you best set this up? Wouldn't the Flex app just be sent the name of the video to play... in which case couldn't someone else write another flex app if they knew the file names? Can Flex play videos hosted on other sites? Is there some clever piece on the server I'm missing, which sits between the Flex video player and the files?

How do I check if a control/DisplayObject is on screen? This means it is displayed on screen so no scrolling needs to be done.Example: I have several controls on a form. The size of the form exceeds the screen length/width. As a result I need scrollbars. How do I check if a control is on screen?

View 3 RepliesI have a popup that contains a TabNavigator control. The tabs are dynamically added to the TabNavigator when the popup loads. Is there a good way to tell when one of the tabs is loaded, from the tab itself?I have a tab that requires a service call to be made, and I don't want the service call to be made unless the user actually goes and clicks the tab to view it. I could notify the tab from the popup control itself when the TabNavigator index was changed, but that doesn't seem like a good way to go about doing it.
