  • programmatically add views to a viewstack flex

    - by dubbeat
    Hi, I'm trying to figure out how to in as3 (not mxml) add views to a view stack. For example I have a view component like so package components.screens { import mx.controls.Label; import mx.core.UIComponent; public class HomeScreen extends UIComponent { private var l:Label=new Label() public function HomeScreen() { super(); l.text="home"; addChild(l) } } } I've being trying to add it to a viewstack in the following way var myStack:ViewStack= new ViewStack(); mystack.addChild(homeScreen) This does not work. Whats the correct way? I'm aware I have to assign ID's but for now I just want to get the view in there

    - by anandhinaveen
    Hello, I am using richfaces dropDownMenu component which contains a set of rich menuItems. When the menu items are displayed, a extra space is displayed before the lablel for each of the menu item. But I have a requirement of not displaying the space before the labels and to change the color. I used the css to reduce the space: .rich-menu-item-icon img { width: 0px; } .rich-menu-group-icon img { width: 0px; } but, i need to change the color in that place.

  • Is there a lightweight datagrid alternative in Flex ?

    - by Wayne
    What is the most performant way of displaying a table of data in Flex? Are there alternatives to the native Flex Datagrid Component? Alternatives that are noted for their rendering speed? Are there other ways to display a table? I have a datagrid with roughly 70 lines and 7 columns of simple text data. This is currently created and loaded in memory. This is being refreshed rapidly (about 800 msec) and there is a slight lag in other animations when it is rendering the table... So I am trying to cut down this render time.

  • Setup Hibernate Session Factory in Tomcat

    - by Mark Estrada
    Hi All, I have been reading around the Hibernate core and I am still exploring some of its capability. It was mention in the docs that the SessionFactory is the heavyweight component of Hibernate thus it should be setup only once in a web application and in singleton. Each Session factory should pertain to one JDBC connection. Does anybody knows how to properly setup the session factory in tomcat web applications? Any links or tutorials would be better. Should I set it up as a contextlistener class also? Thanks.

  • Problem with access to control properties in Multibox

    - by greatromul
    I used multibox-component to create lightbox-similar div. But I faced problem. I placed textbox with id ‘tbx_position’ in that div. I entered some symbols in textbox and then tried to read value via javascript-function (it had to alert document.getElementById(‘tbx_position’).value). Every time that value was empty. There is example of it. Furthermore, if I place in the div asp:Button, server OnClick-eventhandler doesn’t catch fire. Is any idea, what’s reason? Thanks.

  • CRXIR2 doesn't work with VS2010 on Windows 7 nor on Vista

    - by tangens
    We're upgrading from VS2005 to VS2010. We are almost there but there is a problem with Crystal Reports. We use the RDC (COM-based) component within our C++ application. On Windows 7 or on VISTA, I can't get the viewer nor the designer controls working. I get Access Violations when the control is activated: // from atlhost.h (line 2208) hr = m_spOleObject->DoVerb(OLEIVERB_INPLACEACTIVATE, NULL, spClientSite, 0, m_hWnd, &m_rcPos); The strange thing is that when I run the same exe on a XP machine, it seems to work. We basically use "AtlAxWin100" window class to host the Crystal report control ("CrystalReports11.ActiveXReportViewer.1") in. I'm using the SP6 version of Crystal reports so that's the latest version. Also, when I compile the same code with VS2005 and run it on Windows7 or Vista everything works out just fine. Does anybody have any idea about what might cause the problem, or ideas for further investigations?

  • Right method to build a online whiteboard - JAVA

    - by Nikhar Sharma
    I am building a whiteboard, which would have a server(teacher) and clients(students). Teacher would draw something on his side, which will be shown exactly same to the students. I want to know which component i should use to do the drawing? i am currently drawing on JPanel . I want the screen of Server gets copied on the clients, so for that what could be the right method to do this? option1: i save the JPanel as image, and send thru socket, and loads it on the screen of client, also it always saves the background image only, not what the user has drawn onto it. OR option2: both server and client JPanel dimensions are same, so i just send the new coordinates drawn everytime thru socket, with some protocol to understand whether it is rubber or pencil.. Any help would be appreciated.

  • What's a better way to display a handle for resizing a view on iPhone / iPad?

    - by Christian
    I want to display a handle at the corners of a UIView that can be used to resize the view. How can I display the handles floating on the top of everything else and still have a connection to and be in sync with a view? The solution I implemented before looks like this: I put the view into another view that shows the handles on top of the corners. The problem with this approach is that the handles add extra space to the original view's size. Since Apple recommends at least 40 x 40 px for the size of a button, it is not very little space and also goes beyond the visible bounds of the original view. Another problem is that the original view has to be encapsulated in this 'helper view' object and thus becomes a part of something although it really is the main component.

  • Forcing Flex to update the screen?

    - by ABBarton
    This may be a bit of a beginners question, but I can't for the life of me figure it out. I'm using flex to develop a GUI for a large project, specifically a status bar along the bottom. Within my StatusBar class is a ProgressBar, which other classes doing work can tell to update(change bar completion and label) as they progress. The problem I'm encountering is that flex won't update whats shown on the screen until it's too late, for example ProgressBar initialized, 0% done some class sets the ProgressBar to be 12% done some class does some work some class sets the ProgressBar to be 56% done Whats happening is the 12% done is never displaying, it just hangs at 0% during the work, then skips right to 56% done. I've tried to understand the lifecycle of a flex component (invalidation and validation), and I think I understand it and am applying it correctly, but it's not working at all. I need to tell flex to redraw my StatusBar (or at least the ProgressBar within) after some class sets it to be 12% done, but before some class starts doing its work. How do I do this?

  • OOP App Architecture: Which layer does a lazy loader sit in?

    - by JW
    I am planning the implemention an Inheritance Mapper pattern for an application component http://martinfowler.com/eaaCatalog/inheritanceMappers.html One feature it needs to have is for a domain object to reference a large list of aggreageted items (10,000 other domain objects) So I need some kind of lazy loading collection to be passed out of the aggregate root domain object to other domain objects. To keep my (php) model scripts organised i am storing them in two folders: MyComponent\ controllers\ models\ domain\ <- domain objects, DDD repository, DDD factory daccess\ <- PoEAA data mappers, SQL queries etc views\ But now I am racking my brains wondering where my lazy loading collection sits. Any suggestions / justifications for putting it in one place over another another?

  • simple plot algorithm with autoscale

    - by adrin
    I need to implement a simple plotting component in C#(WPF to be more precise). What i have is a collection of data samples containing time (X axis) and a value (both double types). I have a drawing canvas of a fixed size (Width x Height) and a DrawLine method/function that can draw on it. The problem I am facing now is how do I draw the plot so that it is autoscaled? In other words how do I map the samples I have to actual pixels on my Width x Height canvas?

  • How to make Visual C++ 9 not emit code that is actually never called?

    - by sharptooth
    My native C++ COM component uses ATL. In DllRegisterServer() I call CComModule::RegisterServer(): STDAPI DllRegisterServer() { return _Module.RegisterServer(FALSE); // <<< notice FALSE here } FALSE is passed to indicate to not register the type library. ATL is available as sources, so I in fact compile the implementation of CComModule::RegisterServer(). Somewhere down the call stack there's an if statement: if( doRegisterTypeLibrary ) { //<< FALSE goes here // do some stuff, then call RegisterTypeLib() } The compiler sees all of the above code and so it can see that in fact the if condition is always false, yet when I inspect the linker progress messages I see that the reference to RegisterTypeLib() is still there, so the if statement is not eliminated. Can I make Visual C++ 9 perform better static analysis and actually see that some code is never called and not emit that code?

  • Best way to reverse bitmap data that is upside down

    - by Wladimir
    Hello, I have a method that I call and it returns bitmap data from a capture device. It returns a pointer to the buffer data as an IntPtr and the buffer length as an int. I know in advance that this bitmap is a 24bpp and its width and height. The problem is that the buffer contains the bitmap data upside down and I need this data to be in the right order (reverse it). What I do is create a for loop and using CopyMemory, I copy each line (stride) of this data from bottom to up to a newly allocated memory space. Is there any way to make it faster than creating more memory each time I receive a new frame? It makes the application get a bit slow and consumes more memory as each bitmap is pretty big. I do this because I use another component that analyses the bitmaps and it doesn't work propertly if the bitmaps are upside down. I'm using .net, c# thanks!

  • QGLWidget + QGraphicsScene + QGraphicsView problem

    - by matekm
    Hi! I would like to create a simple thumbnail viewer using QGLWidget, QGraphicsScene and QGraphicsView. And I have a problem with placing QGLWidget on QGraphicsScene. The code is similar to this: QGraphicsScene *testScene = new QGraphicsScene (0, 0, 400, 400, 0); QGLWidget *testWidget1 = new QGLWidget(); testWidget1->renderText("Test text1"); QGLWidget *testWidget2 = new QGLWidget(); testWidget2->renderText("Test text2"); testScene->addWidget(testWidget1); testScene->addWidget(testWidget2); QGraphicsView *testView = new QGraphicsView(); testView->setScene(testScene); testView->show() It is possible to place few QGLWidgets on QGraphicsScene/QGraphicsView? Where I doing something wrong? Is there any other component on which I could embed QGLWidgets and show them on the screen? Thanks for help

  • Re-measuring custom item renderer on a List

    - by leolobato
    I'm writing an Adobe Air client to a service similar to Twitter. On the timeline (List component) I have a custom item renderer which is basically a Canvas with a fixed-width Image and a Text control, which is multi-line. If the text is long enough to change the Canvas height, it will only be resized if I manually change the width of the Window, forcing a redraw of all renderers. If I simply scroll through the List, all "new" renderers will have the minimum height possible (which is the Image height). Any ideas on how to force the re-measurement of the renderer when I set it's data? Thanks in advance! :)

  • Why can't I access a web app running on my Mac via my iPhone?

    - by bpapa
    I'm developing an iPhone app that has a network component. I'm developing the app in Java (Google App Engine actually), running on port 8080. And it works, when I test my app in the iPhone simulator. But now I am trying to test on the device, and I can't hit my Jetty instance. I can certainly access my Mac via the iPhone because I'm able to hit http://10.0.1.7/~brianpapa/ and view my Home Folder when Web Sharing is turned on. But when I try to hit http://10.0.1.7:8080/, it says it can't connect to the server. Interestingly, if I try to hit http://10.0.1.7:8080/ from my mac, it doesn't work either - I have to use localhost as the hostname instead, then it's fine. Has anybody ever encountered this before, and know how to fix it?

  • upload an m4a file in flex, saving it as a blob in oracle, and retrieving metadata info from it

    - by Angus
    Hi, I currently have a FileUpload.mxml component that uploads a .m4a to an oracle database, retrieves metadata from the file and saves the metadata info in the database. to acheive this I use FileReference() and set up, amoung others, the dispatcher.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, completeHandler); So the file is posted to a php file which saves it as a blob. Once the blob is saved, the script sends a message back to flex to dispatch the upload_complete_data event. In the complete handler, the metadata is then retreived by reading the value back from the database into a custom made meta data reader. The metadata info is then saved via flex. This seems a little long winded. Has anyone else successfully achieved this using a different way?

  • Why are some VB6 DLLs loaded as mapped files?

    - by Mark Bertenshaw
    Hi - A colleague of mine, whilst trying to figure out the memory useage of our VB6 / C# 2.0 application noticed that a minority of VB6 DLLs have two entries in the SysInternals Process Explorer application. All DLLs have an entry for Mapping = Image, and a specified base address. However, a few also have an entry for Mapping = Data, with a base address of zero, and a much smaller memory useage. I seem to remember something about using mapped memory files to share memory between processes, but we are definitely not doing something as interesting as this. All communication between EXEs is done via COM, and as far as I know, nobody has written a shared memory component. This is not desperate, but I would be very interested in any suggestions as to why some DLLs are loaded as mapped file Thanks, Mark Bertenshaw

  • how to control a embedded multiframe swf file?

    - by liuliu
    [Embed(source="data/fire.swf")] static public var movieFire:Class; I have some multiframe swf file and I want to have control of them. For example, I can use gotoandplay and gotoandstop functionality. I tried something like: var m:MovieClip = new movieFire() as MovieClip; but it turns out when I tried to get totalFrames, m.totalFrames, it gives me zero, and gotoand* functions don't work either. How can I correctly control the swf file embedded in actionsript 3.0 (No Flex component)?

  • OAuth 2.0: Can a user-agent client avoid forwarding fragments?

    - by Bosh
    In the OAuth 2.0 draft specification, user-agent clients receive authorization in the form of a bearer token via redirection (from an authentication server) to a URL such as HTTP/1.1 302 Found Location: http://example.com/rd#access_token=FJQbwq9&expires_in=3600 According to Section 3.5.2 it is then the user-agent's job to GET the URL in question, but "The user-agent SHALL NOT include the fragment component with the request." In other words, as a result of the example redirection above, the user-agent should GET /rd HTTP/1.1 Host: example.com without passing #access_token to the server. My question: what user agents behave this way? I thought redirection in Firefox, for example, would (logically) include the fragment in the GET request. Am I just wrong about this, or does the OAuth 2.0 specification rely on non-standard user-agent behavior?

  • Is is bad practice to put a period in a URI path?

    - by saille
    I am designing a REST API for a web application. I want to clearly version the API so that the interface can be changed in future without breaking existing services. So in my v1.0 API I want to clearly identify it as the v1.0 API, leaving me the freedom to release a future v1.1 version with breaking changes. My question is, would a period in the path component of a URI be bad practice? eg. Is there any good reason not to use http://mysite.com/myapi/v1.0/services as a URI to my service?

  • SOLR and Natural Language Parsing - Can I use it?

    - by andy
    hey guys, my requirements are pretty similar to this: Requirements http://stackoverflow.com/questions/90580/word-frequency-algorithm-for-natural-language-processing Using Solr While the answer for that question is excellent, I was wondering if I could make use of all the time I spent getting to know SOLR for my NLP. I thought of SOLR because: It's got a bunch of tokenizers and performs a lot of NLP. It's pretty use to use out of the box. It's restful distributed app, so it's easy to hook up I've spent some time with it, so using could save me time. Can I use Solr? Although the above reasons are good, I don't know SOLR THAT well, so I need to know if it would be appropriate for my requirements. Ideal Usage Ideally, I'd like to configure SOLR, and then be able to send SOLR some text, and retrieve the indexed tonkenized content. Context So you guys know, I'm working on a small component of a bigger recommendation engine.
