• Set bold rows in a QTreeView

  - by taynaron

  I have a custom subclass of a QTreeView in a pyqt application. I'm trying to give the user the ability to highlight and "lowlight" (for lack of a better term) rows. Highlighted rows should have bold text and (optionally) a different background color. Any ideas? I'm considering StyleSheets as an option, but have so far been unable to get that to work. If I set the QTreeView's stylesheet: self.setStyleSheet("QTreeView::item:selected {border: 1px solid #567dbc;}") I can't figure out how to manually enable 'states' that would keep only the desired rows at a particular state. If I try setting an individual item's stylesheet: #modelIndex is a valid QModelIndex modelIndex.internalPointer().setStyleSheet() I get a segfault. I'm not convinced stylesheets are the way to go, I'm open to all ideas. Thanks!

• Serving files over HTTPS dynamically based on request.ssl? with Attachment_fu

  - by Marston A.

  I see there is a :user_ssl option in attachment_fu which checks the amazon_s3.yml file in order to serve files via https:// In the s3_backend.rb you have this method: def self.protocol @protocol ||= s3_config[:use_ssl] ? 'https://' : 'http://' end But this then makes it serve ALL s3 attachments with SSL. I'd like to make it dynamic depending if the current request was made with https:// i.e: if request.ssl? @protocol = "https://" else @protocol = "http://" end How can I make it work in this way? I've tried modifying the method and then get the NameError: undefined local variable or method `request' for Technoweenie::AttachmentFu::Backends::S3Backend:Module error

• Creating a context in custom shoulda macro does not work.

  - by Honza

  I have a custom should macro in my test_helper.rb which looks like this. def self.should_require_login(actions = [:index]) if (actions.is_a? Symbol) actions = [actions] end context "without user" do actions.each do |action| should "redirect #{action.to_s} away" do get action assert_redirected_to login_path end end end if block_given? context "active user logged in" do setup do @user = Factory.create(:user) @user.register! @user.activate! login_as(@user) end yield end end end I would like to use it like this: should_require_login(:protected_action) do should "do something" do ... end end And I am expecting the "do something" test to run in the "active user logged in" context, but the test executes in the top context, like the "active user logged in" context never existed and I fail to see the reason why.

• Methods in super that will be subclassed anyway (Cocoa)

  - by Michael Matheus

  Sorry if this is a repost but I couldn't quite search for it because I can't explain it in a few words. I have a super class with lots of methods but they will always (not all of them) be subclassed. From the super I need to access (read only) those methods. I could either leave the methods in super empty or I could just not type them in super but call them anyway like so [self myMethod] and it will call my subclassed method even if it doesn't exist in super. This works but Xcode gives me an error though. 'superclass' may not respond to '-subclassmethod' What should I do?

• How to load object after saving with encodeWithCoder?

  - by fuzzygoat

  EDIT_002: Further rewrite: if I save using the method below how would the method to load it back in look? (moons is an NSMutableArray of NSNumbers) // ------------------------------------------------------------------- ** // METHOD_002 // ------------------------------------------------------------------- ** -(void)saveMoons:(NSString *)savePath { NSMutableData *data = [[NSMutableData alloc] init]; NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data]; [moons encodeWithCoder:archiver]; [archiver finishEncoding]; [data writeToFile:savePath atomically:YES]; [archiver release]; [data release]; } EDIT_003: Found it, my problem was that I was using ... [moons encodeWithCoder:archiver]; where I should have been using ... [archiver encodeObject:moons]; Hence the loader would look like: -(void)loadMoons_V3:(NSString *)loadPath { NSData *data = [[NSData alloc] initWithContentsOfFile:loadPath]; NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data]; [self setMoons:[unarchiver decodeObject]]; [unarchiver finishDecoding]; [unarchiver release]; [data release]; } gary

• Python: override __init__ args in __new__

  - by EoghanM

  I have a __new__ method as follows: class MyClass(object): def __new__(cls, *args): new_args = [] args.sort() prev = args.pop(0) while args: next = args.pop(0) if prev.compare(next): prev = prev.combine(next) else: new_args.append(prev) prev = next if some_check(prev): return SomeOtherClass() new_args.append(prev) return super(MyClass, cls).__new__(cls, new_args) def __init__(self, *args): ... However, this fails with a deprecation warning: DeprecationWarning: object.__new__() takes no parameters SomeOtherClass can optionally get created as the args are processed, that's why they are being processed in __new__ and not in __init__ What is the best way to pass new_args to __init__? Otherwise, I'll have to duplicate the processing of args in __init__ (without some_check)

• Addressing a memory leak stops my UI from showing iphone

  - by dubbeat

  Hi I've being getting a memory leak warning with a UITabbarcontroller. If I release the tabbarcontroller the warning goes away but the tabbar will not show any content. If I debug the app with the warning still in it the app runs but will crash after a couple of minutes UITabBarController *tabBarController = [[UITabBarController alloc] init]; tabBarController.view.frame = CGRectMake(0, 0, 320, 460); tabBarController.viewControllers=localControllersArray; // Clean up objects we don't need anymore [promoTabOptionHome release]; [promoTabOptionInfo release]; [promoTabOptionEvents release]; [promoTabOptionBuy release]; [localControllersArray release]; // Finally, add the tab controller view to the parent view [self.view addSubview:tabBarController.view]; //[tabBarController release]; commenting out this line removes the warning but results in no content being shown

• How do I use timezones with a datetime object in python?

  How do I properly represent a different timezone in my timezone?

• How can I create a button with a UIActivityIndicator in my navigation bar with the same style as nor

  - by Jarin Udom

  All of the examples I've seen on here and other sites involved creating a UIActivityIndicatorView and loading it with something like: self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:myActivityIndicatorView target:nil action:nil] autorelease]; However, that just creates a plain activity indicator in the navigation bar. What I want to do is have a button that looks just like the normal UIBarButtonSystemItem buttons but with an activity indicator instead of one of the default images. I've tried doing initWithImage and initWithTitle with nil images or titles and then adding the activity indicator as a subview, but that doesn't work. Any ideas?

• Beginning GWT and Java - wich is the best route when coming from LAMP background?

  - by Cambiata

  Hi! I've worked a lot with php/mysql on linux servers, including frameworks, orm etc. Now I want to give GWT and Java a try! Installing GWT SDK, Eclipse plugin etc and running a "Hello world" is no problem... The server is running automagically in the background... But when it comes to setting it up my self, there seems to be confusingly many options. Jetty? Tomcat? Glassfish? How are those related/combinable to/with Apache? Are there any good resources or tutorials for setting up java development and server environments suited for one like me with PHP background? Maybe pointing out the possiblities of running PHP and Java on the same server? Regards / Jonas

• Apple Magic Trackpad Gestures carried out as personalized Commands in Windows

  - by Adele

  I want to have the Apple Magic Trackpad to work on Windows, but NOT as a regular Mouse! I will need the normal Trackpad Gestures to work with a c# Application (i.e. when carring out a 2 finger swipe to the left, it will start playing a song...). I guess I´ll have to write my own driver? Is there a way to use Apples MAgic Trackpad Driver for Windows and re-write that one? OR is there any way (API, self-written driver), so that I could just hook the gestures to my Commands? Or any RAW Input examples? Does anybody know how to do that, or where to start? Thank you so much, I´m really lost.

• Function Point Analysis -- a seriously over-estimating technique?

  - by kizzx2

  I know questions about FPA has been asked numerous times before, but this time I'm taking a more analytical angle at it, backed up with data. 1. First, some data This question is based on a tutorial. He had a "Sample Count" section where he demonstrated it step by step. You can see some screenshots of his sample application here. In the end, he calculated the unadjusted FP to be 99. There is another article on InformIT with industry data on typical hour/FP. It ranges from 2 hours/FP to 27.4 hours/FP. Let's try to stick with 2 for the moment (since SO readers are probably the more efficient crowd :p). 2. Reality check!? Now just check out the screenshots again. Do a little math here 99 * 2 = 198 hours 198 hours / 40 hours per week = 5 weeks Seriously? That sample application is going to take 5 weeks to implement? Is it just my feeling that it wouldn't take any decent programmer longer than one week to have it completed? Now let's try estimating the cost of the project. We'll use New York's minimum wage at the moment (Wikipedia), which is $7.25 198 * 7.25 = $1435.5 From what I could see from the screenshots, this application is a small excel-improvement app. I could have bought MS Office Pro for 200 bucks which gives me greater interoperability (.xls files) and flexibility (spreadsheets). (For the record, that same Web site has another article discussing productivity. It seems like they typically use 4.2 hours/FP, which gives us even more shocking stats: 99 * 4.2 = 415 hours = 10 weeks = almost 3 whopping months! 415 hours * $7.25 = $3000 zomg (That's even assuming that all our poor coders get the minimum wage!) 3. Am I missing something here? Right now, I could come up with several possible explanation: FPA is really only suited for bigger projects (1000+ FPs) so it becomes extremely inaccurate at smaller scale. The hours/FP metric fluctuates abruptly from team to team, project to project. For a small project like this, we could have used something like 0.5 hour/FP or something. (Now this kind of makes the whole estimation thing pointless, unless my firm does the same type of projects for several years with the same team, not really common.) From my experience with several software metrics, Function Point is really not a lightweight metric. If the hour/FP thing fluctuates so much, then what's the point, maybe I could have gone with User Story Points which is a lot faster to get and arguably almost as uncertain. What would be the FP experts' answers to this?

• Interview - Program on Computer

  - by Gilad Naor

  Spent some time searching, couldn't find exactly what I'm after. We like giving hands-on programming exercises as part of the interview process. The interviewee gets a laptop, with the editor and compiler of his choice. He or she then get a programming exercise and has about an hour to code it. Depending on the nature of the question, internet access is either allowed or forbidden. I'm looking for good general questions for a junior developer. I don't care what language they choose to program in. C++ is as good as Python or Scheme, as long as (s)he can program in it (this rules out "can you write a correct copy-constructor" style questions). I just want to see how they code, if their code is self-documenting, if they write tests, check edge-cases, etc. What kind of questions would you ask?

• iphone: mechanical drawing & layers

  - by d_CFO

  I need to do a bit of mechanical drawing. I can (1) display the part’s image, [self.view addSubview:thePartAsImageView]; (2) implement two sliders (one horizontal for part’s width and one vertical for part’s height), heightSlider.transform = CGAffineTransformRotate(heightSlider.transform, 270.0/180*M_PI); (3) display the corresponding values (dimensions) as the user moves the sliders, and even (4) draw the dimensioning lines with arrowheads: CGContextAddLineToPoint What I can’t do is (5) remove those lines after I’ve drawn them. What I want is “if userTouchedTheHorizontalControl then eraseTheLinesForTheVerticalControl.” If I understand correctly – first, that Quartz composites everything to a single layer, and second, that CALayer, GeekGameBoard and so on only work on Mac -- then I have to do something different. But isn’t there something I can do other than switch to Open GL?

• Try to fill the GAE datastore but the code consumes to much cpu time. How to optimize this?

  - by Neverland

  I try to get the list of images in Amazon EC2 inside the Google datastore. I want to realize this with a cron job inside the GAE. class AmazonEC2uswest(db.Model): ami = db.StringProperty(required=True) mani = db.StringProperty() typ = db.StringProperty() arch = db.StringProperty() state = db.StringProperty() owner = db.StringProperty() class CronAMIsAmazonUS_WEST(webapp.RequestHandler): def get(self): aws_access_key_id_admin = "<secret>" aws_secret_access_key_admin = "<secret>" conn_us_west = boto.ec2.connect_to_region('us-west-1', aws_access_key_id=aws_access_key_id_admin, aws_secret_access_key=aws_secret_access_key_admin, is_secure = False) liste_images_us_west = conn_us_west.get_all_images() laenge_liste_images_us_west = len(liste_images_us_west) for i in range(laenge_liste_images_us_west): datastore_uswest_AMIs = AmazonEC2uswest(ami=liste_images_us_west[i].id, mani=str(liste_images_us_west[i].location), typ=liste_images_us_west[i].type, arch=liste_images_us_west[i].architecture, state=liste_images_us_west[i].state, owner=liste_images_us_west[i].ownerId) datastore_uswest_AMIs.put() The problem: Getting the list with get_all_images() lasts only a few seconds. But writing the data to the Google datastore needs way too much CPU time. My IBM T42p (P4M with 2GHz) needs for that piece of code approx. 1 Minute! Is it possible to optimize my code in a way that it needs fewer CPU time?

• Good conventions for embedding schema of a flat file

  - by Ville Koskinen

  We receive lots of data as flat files: delimitted or just fixed length records. It's sometimes hard to find out what the files actually contain. Are there any well established practices for embedding the schema of the file to the beginning or the end of a file to make the file self-explanatory? Just to get an idea, imagine something like this: <data name=test records=2 type=fixed> <field name=foo start=0 length=2 type=numeric> <field name=bar start=2 length=4 type=text> </data> 11test 12ing We would parse the xml in the beginning and use it for reading the records.

On - (void)request:(FBRequest*)request didLoad:(id)result { I'm trying to obtain the aid returned with this code: else if ([@"Photos.createAlbum" isEqualToString: request.method]) { NSLog(@"[Photos.createAlbum:dialogDidSucceed] succeed"); NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; NSString *aid = [[NSString alloc] initWithString: [request.params objectForKey:@"aid"]]; [prefs setObject:aid forKey:_ALBUMID]; [prefs synchronize]; //[prefs release]; [aid release]; if (pendingUploadImage) { [self btnUploadImage]; } } Here said that the aid is returned, but I don't know where. How can I obtain album id?

• Using table-of-contents in code?

  - by AareP

  Do you use table-of-contents for listing all the functions (and maybe variables) of a class in the beginning of big source code file? I know that alternative to that kind of listing would be to split up big files into smaller classes/files, so that their class declaration would be self-explanatory enough.. but some complex tasks require a lot of code. I'm not sure is it really worth it spending your time subdividing implementation into multiple of files? Or is it ok to create an index-listing additionally to the class/interface declaration?

• UIView animation doesn't work first time

  - by BobC

  Hello everybody, I have a seachButton in the navigation bar which upon hitting calls following method: - (IBAction)search:(id)sender { if (nil == searchViewController) searchViewController = [[SearchViewController alloc] initWithNibName:@"SearchViewController" bundle:nil]; searchViewController.view.backgroundColor = [UIColor clearColor]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:searchViewController.view cache:NO]; [self.view addSubview:searchViewController.view]; [UIView commitAnimations]; } It should load SearchViewController.xib which contains a view with UISearchBar and two buttons. When I call the search method for the first time, the view appears very quickly with some weird animation, when I call it again, the animation is alright. Does anyone have a clue what could be wrong?

• How can I translate my programmatic WCF configuration into app.config

  - by ofer

  Hi, I have an self hosted WCF server with hard coded configurations. the server worked fine until I tried to implement some new functionality. the new setting did not work (urrr.... ) and I find it hard to locate where are the problems in my code. instead of digging inside the code, I thought about different approach: Is there any way to dump those hard coded WCF configuration (the entire ) into app.config like text file after all configurations are loaded? this will enable me to have a easy global view of the entire settings .. mmm .. .by the way, does anyone know a way that will do the translation to the opposite direction? config to code. Any advice will be welcomed! ofer

• Ruby class instance variables and inheritance

  - by rlandster

  I have a Ruby class called LibraryItem. I want to associate with every instance of this class an array of attributes. This array is long and looks something like ['title', 'authors', 'location', ...] Note that these attributes are not really supposed to be methods, just a list of attributes that a LibraryItem has. Next, I want to make a subclass of LibraryItem called LibraryBook that has an array of attributes that includes all the attributes of LibraryItem but will also include many more. Eventually I will want several subclasses of LibraryItem each with their own version of the array @attributes but each adding on to LibraryItem's @attributes (e.g., LibraryBook, LibraryDVD, LibraryMap, etc.). So, here is my attempt: class LibraryItem < Object class << self; attr_accessor :attributes; end @attributes = ['title', 'authors', 'location',] end class LibraryBook < LibraryItem @attributes.push('ISBN', 'pages'] end This does not work. I get the error undefined method `push' for nil:NilClass
