  - by jsight

  Is there a library simplifying the process of dragging and dropping between the Flash/Flex environment and the surrounding browser? I've done some research on the process, and so far the closest thing that I have found is from HTML to Flash in a Floorplanning application. I have yet to find a demo going in the other direction however. Is there a simpler way to do this now?

• How to process large block data visualization with Flex?

  - by hydra1983

  I know that's a big topic. However, it's better to know some general ideas to handle such problems. I have an application which requires Flex to render statistics data calculated instantly on the client side from a downloaded data set. The problems are: the data set is large and needs more than 10 seconds to be downloaded. there are some filters to control the statistics calculation algorithms. If user changes the filters, it would take a long time to recalculate the result and freeze the UI.

• Flex: How do you list private attributes of a class?

  - by mensonge

  Hi, I try to serialize objects with their private attributes, in Flex. The introspection API does not seem to allow it: "The describeType() method returns only public members. The method does not return private members of the caller's superclass or any other class where the caller is not an instance." Is there another way for an instance to know the name of its private members?

• How do I Print a dynamically created Flex component/chart that is not being displayed on the screen?

  - by Adam Jones

  I have a several chart components that I have created in Flex. Basically I have set up a special UI that allows the user to select which of these charts they want to print. When they press the print button each of the selected charts is created dynamically then added to a container. Then I send this container off to FlexPrintJob. i.e. private function prePrint():void { var printSelection:Box = new Box(); printSelection.percentHeight = 100; printSelection.percentWidth = 100; printSelection.visible = true; if (this.chkMyChart1.selected) { var rptMyChart1:Chart1Panel = new Chart1Panel(); rptMyChart1.percentHeight = 100; rptMyChart1.percentWidth = 100; rptMyChart1.visible = true; printSelection.addChild(rptMyChart1); } print(printSelection); } private function print(container:Box):void { var job:FlexPrintJob; job = new FlexPrintJob(); if (job.start()) { job.addObject(container, FlexPrintJobScaleType.MATCH_WIDTH); job.send(); } } This code works fine if the chart is actually displayed somewhere on the page but adding it dynamically as shown above does not. The print dialog will appear but nothing happens when I press OK. So I really have two questions: Is it possible to print flex components/charts when they are not visible on the screen? If so, how do I do it / what am I doing wrong? UPDATE: Well, at least one thing wrong is my use of the percentages in the width and height. Using percentages doesn't really make sense when the Box is not contained in another object. Changing the height and width to fixed values actually allows the printing to progress and solves my initial problem. printSelection.height = 100; printSelection.width = 100; But a new problem arises in that instead of seeing my chart, I see a black box instead. I have previously resolved this issue by setting the background colour of the chart to #FFFFFF but this doesn't seem to be working this time. UPDATE 2: I have seen some examples on the adobe site that add the container to the application but don't include it in the layout. This looks like the way to go. i.e. printSelection.includeInLayout = false; addChild(printSelection);
