  • General advice about scaling on QGraphicsView/QGraphicsScene

    - by onurozcelik
    Hi, In my project I am using QGraphicsView/QGraphicsScene stuff. On my scene there will be regions that contains 2D graphics. Region count will be limited(Lets say 20) Users can choose to display one or more regions. If user choose to display one region I am going to show one region on scene If user choose to display n regions I am going to show n regions on scene I need a scaling logic to fit n regions on same scene. How can I achieve this?

  • JSON and Microformats

    - by Tauren
    I'm looking for opinions on whether microformats should be used to name JSON elements. For instance, there is a microformat for physical addresses, that looks like this: <div class="adr"> <div class="street-address">665 3rd St.</div> <div class="extended-address">Suite 207</div> <span class="locality">San Francisco</span>, <span class="region">CA</span> <span class="postal-code">94107</span> <div class="country-name">U.S.A.</div> </div> There is a document available on using JSON and Microformats. The information above could be represented as JSON data like this: "adr": { "street-address":"665 3rd St.", "extended-address":"Suite 207", "locality":"San Fransicso", "region":"CA", "postal-code":"94107", "country-name":"U.S.A." }, The issue I have with this is that I'd like my JSON data to be as lightweight as possible, but still human readable. While still supporting international addresses, I would prefer something like this: "address": { "street":"665 3rd St.", "extended":"Suite 207", "locality":"San Fransicso", "region":"CA", "code":"94107", "country":"U.S.A." }, If I'm designing a new JSON API right now, does it make sense to use microformats from the start? Or should I not really worry about it? Is there some other standard that is more specific to JSON that I should look at?

  • debuging native code (C++) using gdb on android with Eclipse. Is it possible?

    - by noisy
    Hi, I have some piece of code which uses JNI. I can debug code wrote in Java directly in Eclipse (using ADT). I even have a script, which help me debug native code with gdb. However this is not very comfortable way for doing this. Is it possible to configure Eclipse to use gdb (I guess gdbserver) for debbuging android native applications? Do you know where I could find any description of this?

  • asp.net 3.5 on windows 2000

    - by SiC
    Hi, I am trying to get an ASP.net 3.5 site to run on a windows 2000 machine (not my idea!!!) but am having some problems. I have been working through copying required dlls from C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5 into my app bin directory. This succesfully got me past the "assembly not found" errors. However, I am now getting the error: "Compiler executable file csc.exe cannot be found". Does anyone know how I can fix this? It is primarily LINQ functionality I am looking to utilise. Many thanks!!

  • How can I store large amount of data from a database to XML (memory problem)?

    - by Andrija
    First, I had a problem with getting the data from the Database, it took too much memory and failed. I've set -Xmx1500M and I'm using scrolling ResultSet so that was taken care of. Now I need to make an XML from the data, but I can't put it in one file. At the moment, I'm doing it like this: while(rs.next()){ i++; xmlStringBuilder.append("\n\t<row>"); xmlStringBuilder.append("\n\t\t<ID>" + Util.transformToHTML(rs.getInt("id")) + "</ID>"); xmlStringBuilder.append("\n\t\t<JED_ID>" + Util.transformToHTML(rs.getInt("jed_id")) + "</JED_ID>"); xmlStringBuilder.append("\n\t\t<IME_PJ>" + Util.transformToHTML(rs.getString("ime_pj")) + "</IME_PJ>"); //etc. xmlStringBuilder.append("\n\t</row>"); if (i%100000 == 0){ //stores the data to a file with the name i.xml storeKBR(xmlStringBuilder.toString(),i); xmlStringBuilder= null; xmlStringBuilder= new StringBuilder(); } and it works; I get 12 100 MB files. Now, what I'd like to do is to do is have all that data in one file (which I then compress) but if just remove the if part, I go out of memory. I thought about trying to write to a file, closing it, then opening, but that wouldn't get me much since I'd have to load the file to memory when I open it. P.S. If there's a better way to release the Builder, do let me know :)

  • Intersection of sets Mongodb

    - by afvasd
    Hi everyone I am new to mongo, this is my db design: product := { name: str group: ref, comments: [ ref, ref, ref, ref ] } comments := { ... a bunch of comments stuff } tag := { _id: int, #Need this for online requests tag: str, products: [ {product: ref, score: float}, ... ], comments: [ {comment: ref, score: float}, ...], } So my usage pattern is: GIVEN a product, find comments that have certain tag and sort them accordingly. My current approach involves: Look for that tag object that has tag=myTag pull all the comments out, sorted look for that product where product.name=myProduct pull all the comments out (which are dbrefs by the way) loop through the result of 2, and checking if they are in 4, (this I can do a limit 10) etc. It's pretty inefficient. Any better methods?

  • Run GTK+ application in client browser

    - by mgray
    Hi, I've been searching for ways to run a GTK+ application on a browser. WebKit and its associated GTK+ port seem to do the opposite - making applications more Web-friendly, but the opposite would also be nice. There seems to have been some activity to realize that for XCode, with Cappuccino and Atlas, that can translate NIB files into CIB files. If anyone can point me in the right direction, I'd really appreciate it! Thanks! mike

  • Silverlight XML editor / syntax highlighting

    - by Gromix
    Hi, I am looking for a Silverlight text editor control that provides XML syntax highlighting. I found a few answers in Winforms or WPF, like here on Stackoverflow, but I didn't manage to convert them to Silverlight. The fact that Silverlight is missing System.Drawing is probably a big problem. The only text editor I found for Silverlight is RichTextEdit on Codeplex, but I don't think it is a suitable base for real-time syntax highlighting. Has anyone heard of such a control, or can provide hints on how to build one? Many thanks, Romain

  • MySQL Server - Got error -1 from storage engine

    - by Bobby
    I am currently trying to restore a MySQL table from the .ibd file. I have been following the instructions on the MySQL reference manual on how to use DISCARD and IMPORT TABLESPACE to replace the .idb files. Discarding the tablespace returns no error and the file is deleted however IMPORTING the replacement .ibd file yields a "Got error -1 from storage engine" error. There doesn't seem to be too much information about what exactly an error -1 is. Does anybody have any further insight as to why an import table space isn't working?

  • How to handle too many files in Qt

    - by mree
    I'm not sure how to ask this, but here goes the question: I'm migrating from J2SE to Qt. After creating some small applications in Qt, I noticed that I've created way too many files compared to what I would've create if I was developing in Java (I use Netbeans). For an example, for a GUI to Orders, I'd have to create Main Order Search Window Edit Order Dialog Manage Order Dialog Maybe some other dialogs... For Java, I don't have to create a new file for every new Dialog, the Dialog will be created in the JFrame class itself. So, I will only be seeing 1 file for Orders which has other Dialogs in it. However, in Qt, I'd have to create 1 ui file, 1 header file, 1 cpp file for each of the Dialog (I know I can just put the cpp in the header, but it's easier to view codes in seperate files). So, in the end, I might end up with 3 (if there are 3 dialogs) x3 files = 9 files for the GUI in Qt, compared to Java which is only 1 file. I do know that I can create a GUI by coding it manually. But it seems easy on small GUIs but not some on complicated GUIs with lots of inputs, tabs and etc. So, is there any suggestion on how to minimize the file created in Qt?

  • Holiday Book Recommendation

    - by dalton
    I'm after a book to read whilst on holiday. Some criteria: The book has to be relatively short. < 500 pages. I'd prefer a book that changes your thinking, rather than reams of syntax to look at. So the last two years here have been my books: Last year, The Craftsman by Richard Sennet (Changed how I viewed career development, quality) Year before, Zen and The art of motorcycle maintenance (Makes you think about quality, maintenance)

  • How to use python to create a GUI application which have cool animation/effects under Linux (like 3D

    - by sgon00
    Hi, I am not sure if my question title makes sense to you or not. I am seeing many cool applications which have cool animations/effects. I would like to learn how to use python to create this kind of GUI applications under Linux. "cool animation/effects" like 3D wall in Cooliris which is written in flash and compiz effects with opengl. I also heard of some python GUI library like wxPython and pyQT. Since I am completely new to python GUI programming, can anyone suggest me where to start and what I should learn to achieve and create such application? maybe learn pyQT with openGL feature? pyopengl binding? I have no clue on where to start. thank you very much for your time and suggestion. By the way, in case if someone need to know which kind of application I am going to create, well, just any kind of applications. maybe photo explorer with 3D wall, maybe IM client, maybe facebook client etc...

  • UISearchDisplayController not working when created in code??

    - by Nick Bedford
    I'm working on a tab bar application and one of the tabs has a UISearchDisplayController hooked up to a UISearchBar. It's all connected up in the NIB and is working. When I tap the search bar, the Scope and Cancel buttons fly in etc, and the search delegate updates the results table correctly. However, I'm trying to implement the same code in the viewDidLoad message instead of the NIB, however when I delete the search display controller from the NIB and uncomment my code to create the same controller in the function, it doesn't work. It's as if there's some fundamental connection not being made so that all my search delegate functionality isn't being called. Here's my working NIB version of the Search Display Controller. It's hooked up to the search bar, the UINavigationController subclass (MASearchController) and the root view of that is hooked up as the searchContentsController. Now this is what you would expect to do in code to create the same, right? What I'm doing is leaving the UISearchBar in the NIB to eliminate one piece of the puzzle at a time in code. // [MASearchController viewDidLoad] UISearchDisplayController *searchController = [[[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:[[self viewControllers] objectAtIndex:0]] autorelease]; [searchController setDelegate:self]; [searchController setSearchResultsDelegate:self]; [searchController setSearchResultsDataSource:self]; I've checked all objects at run time and they all check out. Essentially I've deleted the search display controller from the NIB and then put in the code to create it in the viewDidLoad message. Why would this not work? The search keyboard comes up but none of my search and button animation functionality work???
