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 1 RepliesThe following is my codes. This is still work in progress; so, you will see some functions with empty contents. Plus, this is my first Flex application; please bear with me. This is a quiz application that gets the questions and answers to each questions from a ColdFusion web service. There are three types of questions, True or False, Multiple Choice with single selection, and Multiple Choice with multiple selections. So, based upon the question type, the application would dynamically generate the appropriate amount of radio buttons or check boxes for the users to select. I got these working. The problem that I am having is, I am not sure how to check what the users have actually selected. In some other forums and posts on other web site, it said that I can use event.currentTarget.selectedValue to get the user selection. But when I actually do it, I got a run-time error saying, "Property selectedValue not found on mx.controls.FormItem and there is no default value." My question is, what do I need to do to capture the user selections?

Making an Flex App. Just wondering if anyone has created something that fits automatically to the users' screen size and how I go about doing this? One of the principle things is that I need an background image, which is obviously going to have to scale / resize to match the users screen.
View 1 RepliesCut and pasted example with buttons for videodisplay control in chp 9 of Adobe Flex 3 developer guide. Having problems.
History - take avi, create flv. In my mxml, file define mx:videodisplay, refs flv file and define buttons for play and pause, all within mx:application.
Compile mxml with mxmlc to create swf. Call swf file within html using <object> and <embed>. Run html.Result is that the buutons show but the video control is black - no video.i have written mxml file as an air file (so use mx:windowedApplication) and compile with amxmlc and the resultant app runs as expected.I can also convert the flv into an swf file and run that from html but then I do not get buttons.
I am trying to manipulate (move up and down, enable/disable and launch a form) child controls inside a panel control.

I 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.
I'm working on a video player with full screen capabilities. I have the control bar set to tween in and out of the video screen with a mouse event. I'm also trying to position the control bar at the bottom of the screen when it's in full screen mode. My problem is that the control bar doesn't reposition when in full screen because of the tween functions. I'm thinking that whatever solution comes up that I might go in the if statement of the full screen code.

View 2 RepliesI 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:
