  • iPhone: scale UIView about a specific point

    - by Greg Maletic
    I want to animate the scaling down of a UIView, but not about its center: about a different point. As a shot in the dark, I tried translating the view, scaling, then translating back, using a series of CGAffineTransforms. But it doesn't work: it still scales about the center. Anyone know how to do this? Thanks very much.

  • JPA entity design / cannot delete entity

    - by timaschew
    I though its simple what I want, but I cannot find any solution for my problem. I'm using playframework 1.2.3 and it's using Hibernate as JPA. So I think playframework has nothing to do with the problem. I have some classes (I omit the nonrelevant fields) public class User { ... } public class Task { public DataContainer dataContainer; } public class DataContainer { public Session session; public User user; } public class Session { ... } So I have association from Task to DataContainer and from DataContainer to Sesssion and the DataContainer belongs to a User. The DataContainers can have always the same User, but the Session have to be different for each instance. And the DataContainer of a Task have also to be different in each instance. A DataContainer can have a Sesesion or not (it's optinal). I use only unidirectional assoc. It should be sufficient. In other words: Every Task must has one DataContainer. Every DataContainer must has one/the same User and can have one Session. To create a DB schema I use JPA annotations: @Entity public class User extends Model { ... } @Entity public class Task extends Model { @OneToOne(optional = false, cascade = CascadeType.ALL) public DataContainer dataContainer; } @Entity public class DataContainer extends Model { @OneToOne(optional = true, cascade = CascadeType.ALL) public Session session; @ManyToOne(optional = false, cascade = CascadeType.ALL) public User user; } @Entity public class Session extends Model { ... } BTW: Model is a play class and provides the primary id as long type. When I create some for each entity a object and 'connect them', I mean the associations, it works fine. But when I try to delete a Session, I get a constraint violation exception, because a DataContainer still refers to the Session I want to delete. I want that the Session (field) of the DataContainer will be set to null respectively the foreign key (session_id) should be unset in the database. This will be okay, because its optional. I don't know, I think I have multiple problems. Am I using the right annotation @OneToOne ? I found on the internet some additional annotation and attributes: @JoinColumn and a mappedBy attribute for the inverse relationship. But I don't have it, because its not bidirectional. Or is a bidirectional assoc. essentially? Another try was to use @OnDelete(action = OnDeleteAction.CASCADE) the the contraint changed from NO ACTIONs when update or delete to: ADD CONSTRAINT fk4745c17e6a46a56 FOREIGN KEY (session_id) REFERENCES annotation_session (id) MATCH SIMPLE ON UPDATE NO ACTION ON DELETE CASCADE; But in this case, when I delete a session, the DataContainer and User is deleted. That's wrong for me. EDIT: I'm using postgresql 9, the jdbc stuff is included in play, my only db config is db=postgres://app:app@localhost:5432/app

  • Port Flash to iPhone

    - by LaGrad
    How hard would it be to port a flash game to the iPhone. Obviously Flash CS5 is no longer an options, I still would like to know if there's anything that can be reused? or do I have to write everything from scratch (Is Obj-C that different than ActionScript?) Is there any other shortcuts? Also, if anyone has done this before please share your experience.

  • java.util.zip - ZipInputStream v.s. ZipFile

    - by lucho
    Hello, community! I have some general questions regarding the java.util.zip library. What we basically do is an import and an export of many small components. Previously these components were imported and exported using a single big file, e.g.: <component-type-a id="1"/> <component-type-a id="2"/> <component-type-a id="N"/> <component-type-b id="1"/> <component-type-b id="2"/> <component-type-b id="N"/> Please note that the order of the components during import is relevant. Now every component should occupy its own file which should be externally versioned, QA-ed, bla, bla. We decided that the output of our export should be a zip file (with all these files in) and the input of our import should be a similar zip file. We do not want to explode the zip in our system. We do not want opening separate streams for each of the small files. My current questions: Q1. May the ZipInputStream guarantee that the zip entries (the little files) will be read in the same order in which they were inserted by our export that uses ZipOutputStream? I assume reading is something like: ZipInputStream zis = new ZipInputStream(new BufferedInputStream(fis)); ZipEntry entry; while((entry = zis.getNextEntry()) != null) { //read from zis until available } I know that the central zip directory is put at the end of the zip file but nevertheless the file entries inside have sequential order. I also know that relying on the order is an ugly idea but I just want to have all the facts in mind. Q2. If I use ZipFile (which I prefer) what is the performance impact of calling getInputStream() hundreds of times? Will it be much slower than the ZipInputStream solution? The zip is opened only once and ZipFile is backed by RandomAccessFile - is this correct? I assume reading is something like: ZipFile zipfile = new ZipFile(argv[0]); Enumeration e = zipfile.entries();//TODO: assure the order of the entries while(e.hasMoreElements()) { entry = (ZipEntry) e.nextElement(); is = zipfile.getInputStream(entry)); } Q3. Are the input streams retrieved from the same ZipFile thread safe (e.g. may I read different entries in different threads simultaneously)? Any performance penalties? Thanks for your answers!

  • Django model fields getter / setter

    - by pistacchio
    Hi, is there something like getters and setters for django model's fields? For example, I have a text field in which i need to make a string replace before it get saved (in the admin panel, for both insert and update operations) and make another, different replace each time it is read. Those string replace are dynamic and need to be done at the moment of saving and reading. As I'm using python 2.5, I cannot use python 2.6 getters / setters. Any help?

  • XSL Transform SVG to VML

    - by kzh
    I don't know anything about VML except that Internet Explorer and other Microsoft products use it and that it is a vector graphics format. Can one use XSLT to transform an SVG document to VML? Or are they too different from one another to make this possible? I know that there exist XSLT documents to transform SVG to XAML.

  • Eclipse RCP and JFace: Problems with Images in Context menu and TreeViewer

    - by Juri
    I'm working on an Eclipse RCP application. Today I experienced some troubles when displaying images in the context menu. What I wanted to do is to add a column to my table containing images of stars for representing a user rating. On Windows, this causes some problems, since the star images are squeezed up on the left corner of the table cell instead of expanding on the whole cell, but I'll solve that somehow. In addition I have a context menu on the table, with an entry called "rate" where again the different stars from 1 to 5 (representing the rating level) are shown, such that the user can click on it for choosing different ratings. That works fine on Windows. Now I switched to Linux (Ubuntu) to see how it works out there, and strangely, the stars in the table cell are layed out perfectly, while the stars on the context menu don't even show up. On the context menu I'm using an action class where I'm setting the image descriptor for the star images: public class RateAction extends Action { private final int fRating; private IStructuredSelection fSelection; public RateAction(int rating, IStructuredSelection selection) { super("", AS_CHECK_BOX); fRating = rating; fSelection = selection; setImageDescriptor(createImageDescriptor()); } /** * Creates the correct ImageDescriptor depending on the given rating * @return */ private ImageDescriptor createImageDescriptor() { ImageDescriptor imgDescriptor = null; switch (fRating) { case 0: return OwlUI.NEWS_STARON_0; case 1: return OwlUI.NEWS_STARON_1; case 2: return OwlUI.NEWS_STARON_2; case 3: return OwlUI.NEWS_STARON_3; case 4: return OwlUI.NEWS_STARON_4; case 5: return OwlUI.NEWS_STARON_5; default: break; } return imgDescriptor; } /* * @see org.eclipse.jface.action.Action#getText() */ @Override public String getText() { //return no text, since the images of the stars will be displayed return ""; } ... } Does somebody know why this strange behaviour appears? Thanks a lot. (For some strange reason, the images don't appear. Here are the direct URLs: http://img187.imageshack.us/img187/4427/starsratingho4.png http://img514.imageshack.us/img514/8673/contextmenuproblemgt1.png) //Edit: I did some tries and it seems as if the images just don't appear when using a Checkbox style for the context menu (see constructor of the RateAction). When I switched to a PushButton style, the images appeared, although not correctly scaled, but at least they were shown.

  • git rebase from a url/path

    - by edA-qa mort-ora-y
    Why can I not rebase from the same location that I can pull? For example, if I am in a pository I can pull from another repository: git pull /path/to/other But I cannot rebase from that other repository; the following fails: git rebase /path/to/other The help for rebase doesn't mention any refspec's, so I don't know how, or even if, I can/should specify them. How can I rebase from a different location?

  • Can User have more than one roles in asp.net

    - by madness800
    I'm developing a web application I want to use the role authentication to control different parts of the website accessibility. But my problem is say I implemented a upload and download functionality on one of the page and I want to have the ability to control a user whether they can either upload or download; or both. So, I'm not exactly sure if the role base authentication can support a user with more than one role to work the way I want it.

  • Objects do not retain the frame that I give then when using CGAffineTransforms with Core Animation

    - by user170030
    Hi, I'm making a game where when a card is touched, it grows so that it is focused, and when you 'let go', it goes back to its original size and place. This seems pretty standard, however, when I add cards and move the hand around to accommodate different numbers of cards, touching the card makes it go to its original place, and not to the new place. This has been stumping me for a while now Any hints would be much appreciated. Thanks !

  • Non Document Centric SharePoint Workflow

    - by Dan Revell
    SharePoint workflows are document centric in that the base thing the workflow runs on has to be a thing; be it a document or just a list item. The workflow itself is task based, so stuff a user has to do. Now I can put any sort of code in these tasks that I want to and even put complex InfoPath forms in for the user to perform the task. This has been fine on all my previous workflows. But what if I want the tasks to be actual official forms themselves. The item that the workflow runs on is just some abstract concept like an event. An example could be an accident has happened. There isn't an accident form, but a whole set of forms that need to be completed by different people. Task forms aren't really a nice way to go, because it locks all the forms into the task list. You can only access the forms by not deleting the tasks when complete and going to the workflow summery and following the task links to the InfoPath forms or going straight to the tasks list and doing a filter on particular "accidents". These are official documents so ideally there would be a library for each type of document and the workflow would orchestrate the completion of the right forms. It would mean each task would have to create a new blank form and then link the user to that form. The user would go complete the form but then have to go back to the task form and click yes I've completed it until the workflow could progress. Well this is short of the workflow monitoring the forms library form for some completion trigger. But then it all gets messy with the user experience from clicking the link in the task email, to open the Infopath task form, to clicking the link in the subsequent Infopath library form and then return through these forms on completion. It just gets messy trying to retrofit this non document centric sort of workflow into SharePoint. I would really appreciate any input on what might be the best way to do this. Store the forms as task forms Store the forms as library forms and create/link from the task forms Store the forms as different infopath views, and use a forms library. The workflow would trigger variables that progress the view the infopath form shows. Using the same form template for both task forms and a forms library and when a task form is complete, copy the xml into the forms library to have a official record outside of the workflow. Thanks

  • Python 3 with numpy and object refernces

    - by user963386
    I need to create a large matrix (array) structure (3 axis) and each element should store the reference to a Python object (myclass instance). Is it possible to use numpy to create such an array. Which data type should I use in order to store Python references? The advantage of numpy is the support of slicing at different levels. The alternativee is to create a nested (nested) list but it is a cumbersome solution.

  • RESTful principles question

    - by auser
    An intelligent coworker friend of mine brought up a question to me that I was uncertain how to answer and I'd like to pose it to the world. If a RESTful endpoint uses token-based authentication, aka a time-based token is required to access a resource and that token expires after a certain amount of time, would this violate the RESTful principle? In other words, if the same URL expires after a certain amount of time, so the resource returns a different response depending when it was requested, is that breaking REST?

  • Uploading file to multiple servers ?

    - by WarDoGG
    I'm creating an image uploader which will give the user an option to upload file to a different server than which the script is hosted on. Is making an FTP connection from the script server to the target uploading server the only way to do this ? Correct me if im wrong, but would the path of the file look like this ? User computer (file) --- script server ---- target server Is there another way to do this ?
