  • how to close a java frame with threads

    - by user261002
    I have a java frame that I want to close it automatically after 3 or 4 seconds. I found out I must used threads. but I dont know how exactly to do it, this a dumy part of my code : package intro; import java.awt.*; import java.io.IOException; //import view.LangMenu; public class IntroClass extends Frame { private int _screenWidth = 0; private int _screenHeight = 0; private int _screenCenterx = 0; private int _screenCentery = 0; //private static final String SOUND_PATH="/sounds/introSound.midi"; public IntroClass() { Toolkit thisScreen = Toolkit.getDefaultToolkit(); Dimension thisScrrensize = thisScreen.getScreenSize(); _screenWidth = thisScrrensize.width; _screenHeight = thisScrrensize.height; _screenCenterx = _screenWidth / 2; _screenCentery = _screenHeight / 2; setBackground(Color.pink); Label lbl = new Label("Welcome To Dots Game. Samaneh Khaleghi", Label.CENTER); add(lbl); setUndecorated(true); setLocation((_screenCenterx*50)/100,_screenCentery-(_screenCentery*50)/100); setSize((_screenWidth * 50) / 100, (_screenHeight * 50) / 100); WaitClass r = new WaitClass(); r.start(); view.DotsBoardFrame d=new view.DotsBoardFrame(); main.Main.showScreen(d); } class WaitClass extends Thread { boolean running = true; public void run() { while (running) { try { Thread.sleep(50); } catch (InterruptedException ex) { ex.printStackTrace(); } } } } }

  • questions about using svn

    - by ajsie
    i have set up a svn repository in a remote ubuntu server using webdav (http://ip/svn). but i have some questions: should i create one svn repository for each project folder? so i should use "svnadmin create" 5 times for 5 projects? or should i import them to seperate folders in the svn repository? should i after i have created a svn repo, import one project folder into it with "svn import" and then DELETE my original local folder thus only having it in the svn repo in the remote ubuntu server? is this safe or should i still have a local copy for some reason (cause i wont work in that one)? i use netbeans to check out projects from svn repo, then i edit the files and commit the changes. but how should i do to update the live web server content (in /var/www)? should i in my ubuntu server use "svn checkout" and check it out to /var/www or should i use netbeans to check out to a local folder and then upload the files to /var/www with ftp or webdav (and which one of them should i use)? so i got a svn repo and lets say 4 programmers are working with it, checking out and commiting. how do i check what is happening in the repo, which one made which changes, and all the changes from day 1 to day 213? does netbeans/eclipse letting me see this kind of information or do i download another application for it? i should have one svn user for each programmer in the ubuntu server? is this accomplished by using "htpasswd" 4 times for 4 programmers? how do i couple all these users to same group so that i could modify file access specific for the svn group and all its members?

  • Help creating custom iPhone Classes

    - by seanny94
    This should be a simple question, but I just can't seem to figure it out. I'm trying to create my own class which will provide a simpler way of playing short sounds using the AudioToolbox framework as provided by Apple. When I import these files into my project and attempt to utilize them, they just don't seem to work. I was hoping someone would shed some light on what I may be doing wrong here. simplesound.h #import <Foundation/Foundation.h> @interface simplesound : NSObject { IBOutlet UILabel *statusLabel; } @property(nonatomic, retain) UILabel *statusLabel; - (void)playSimple:(NSString *)url; @end simplesound.m #import "simplesound.h" @implementation simplesound @synthesize statusLabel; - (void)playSimple:(NSString *)url { if (url = @"vibrate") { AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); statusLabel.text = @"VIBRATED!"; } else { NSString *paths = [[NSBundle mainBundle] resourcePath]; NSString *audioF1ile = [paths stringByAppendingPathComponent:url]; NSURL *audioURL = [NSURL fileURLWithPath:audioFile isDirectory:NO]; SystemSoundID mySSID; OSStatus error = AudioServicesCreateSystemSoundID ((CFURLRef)audioURL,&mySSID); AudioServicesAddSystemSoundCompletion(mySSID,NULL,NULL,simpleSoundDone,NULL); if (error) { statusLabel.text = [NSString stringWithFormat:@"Error: %d",error]; } else { AudioServicesPlaySystemSound(mySSID); } } static void simpleSoundDone (SystemSoundID mySSID, void *args) { AudioServicesDisposeSystemSoundID (mySSID); } } - (void)dealloc { [url release]; } @end Does anyone see what I'm trying to accomplish here? Does anyone know how to remedy this code that is supposedly wrong?

  • How does asp.net MVC remember my incorrect values on postback?

    - by Michel
    This is working, but how??? I have a controller action for a post: [AcceptVerbs(HttpVerbs.Post )] public ActionResult Edit(Person person) { bool isvalid = ModelState.IsValid; etc. The Person object has a property BirthDate, type DateTime. When i enter some invalid data in the form, say 'blabla' which is obvious not a valid Datetime, it fills all the (other) Person properties with the correct data and the BirthDate property with a new blank DateTime. The bool isvalid has the value 'false'. So far so good. Then i do this: return View(p); and in the view i have this: <%= Html.TextBox("BirthDate", String.Format("{0:g}", Model.BirthDate)) %> <%= Html.ValidationMessage("BirthDate", "*") %> Ant there it comes: i EXPECTED the model to contain the new, blank DateTime because i didn't put any new data in. Second, when the View displays something, it must be a DateTime, because Model.BirthDate can't hold anything but a DateTime. But to my surprise, it shows a textbox with the 'blabla' value! (and the red * behind it) Which ofcourse is nice because the user can seee what he typed wrong, but how can that (blabla)string be transferred to the View in a DateTime field?

  • Is ADO.NET Entity framework database schema update possible ?

    - by fyasar
    Hi All I'm working on proof of concept application like crm and i need your some advice. My application's data layer completely dynamic and run onto EF 3.5. When the user update the entity, change relation or add new column to the database, first i'm planning make for these with custom classes. After I rebuild my database model layer with new changes during the application runtime. And my model layer tie with tightly coupled to my project for easy reflecting model layer changes (It connected to my project via interfaces and loading onto to application domain in the runtime). I need to create dynamic entities, create entity relations and modify them during the runtime after that i need to create change database script for updating database schema. I know ADO.NET team says "we will be able to provide this property in EF 4.0", but i don't need to wait for them. How can i update database changes during the runtime via EF 3.5 ? For example, i need to create new entity or need to change some entity schema, add new properties or change property types after than how can apply these changes on the physical database schema ? Any ideas ?

  • Django notification get date one accesses a link

    - by dana
    hi there, i'm making a notification system, so that a user in a virtual community to be announced when someone sends him a message, or starts following him (the follow relation is like a friend relation, but it is not necessarily reciprocal) my view function: def notification_view(request, last_checked): u = Relation.objects.filter(date_follow>Notification.objects.get(last_checked=last_checked)) v = Message.objects.filter(date>Notification.objects.get(last_checked=last_checked)) if u: notification_type = follow if notice_settings == receive_notification or notice_settings == only_follow following = u if v: notification_type = message if notice_settings == receive_notification or notice_settings == only_messages message = v return render_to_response('notification/notification.html', { 'following': following, 'message':message, }, context_instance=RequestContext(request)) the models.py: class NoticeType(models.Model): follow = models.ForeignKey(Relations, editable = False) message = models.ForeignKey(Messages) classroom_invitation = models.ForeignKey(Classroom) class Notification(models.Model): receiver = models.ForeignKey(User, editable=False) date = models.DateTimeField(auto_now=True, editable = False) notice_type = models.ForeignKey(NoticeType, editable = False, related_name = "notification_type") sent = models.BooleanField(default = True) last_checked = models.DateTimeField(auto_now=True, editable = False) class NotificationSettings(models.Model): user = models.ForeignKey(User) receive_notifications = models.BooleanField(default = True) only_follow = models.BooleanField(default = False) only_message = models.BooleanField(default = False) only_classroom = models.BooleanField(default = False) #receive_on_email = models.BooleanField(default = False) my problem is: i want last_checked to be the time when someone acceses a link (the notification link). How can i possibily save that time? how can i get it? thanks in avance!

  • Python Twisted Client Connection Lost

    - by MovieYoda
    I have this twisted client, which connects with a twisted server having an index. I ran this client from command-line. It worked fine. Now I modified it to run in loop (see main()) so that I can keep querying. But the client runs only once. Next time it simply says connection lost \n Connection lost - goodbye!. What am i doing wrong? In the loop I am reconnecting to the server, it that wrong? from twisted.internet import reactor from twisted.internet import protocol from settings import AS_SERVER_HOST, AS_SERVER_PORT # a client protocol class Spell_client(protocol.Protocol): """Once connected, send a message, then print the result.""" def connectionMade(self): self.transport.write(self.factory.query) def dataReceived(self, data): "As soon as any data is received, write it back." if data == '!': self.factory.results = '' else: self.factory.results = data self.transport.loseConnection() def connectionLost(self, reason): print "\tconnection lost" class Spell_Factory(protocol.ClientFactory): protocol = Spell_client def __init__(self, query): self.query = query self.results = '' def clientConnectionFailed(self, connector, reason): print "\tConnection failed - goodbye!" reactor.stop() def clientConnectionLost(self, connector, reason): print "\tConnection lost - goodbye!" reactor.stop() # this connects the protocol to a server runing on port 8090 def main(): print 'Connecting to %s:%d' % (AS_SERVER_HOST, AS_SERVER_PORT) while True: print query = raw_input("Query:") if query == '': return f = Spell_Factory(query) reactor.connectTCP(AS_SERVER_HOST, AS_SERVER_PORT, f) reactor.run() print f.results return if __name__ == '__main__': main()

  • How can I superimpose modified loess lines on a ggplot2 qplot?

    - by briandk
    Background Right now, I'm creating a multiple-predictor linear model and generating diagnostic plots to assess regression assumptions. (It's for a multiple regression analysis stats class that I'm loving at the moment :-) My textbook (Cohen, Cohen, West, and Aiken 2003) recommends plotting each predictor against the residuals to make sure that: The residuals don't systematically covary with the predictor The residuals are homoscedastic with respect to each predictor in the model On point (2), my textbook has this to say: Some statistical packages allow the analyst to plot lowess fit lines at the mean of the residuals (0-line), 1 standard deviation above the mean, and 1 standard deviation below the mean of the residuals....In the present case {their example}, the two lines {mean + 1sd and mean - 1sd} remain roughly parallel to the lowess {0} line, consistent with the interpretation that the variance of the residuals does not change as a function of X. (p. 131) How can I modify loess lines? I know how to generate a scatterplot with a "0-line,": # First, I'll make a simple linear model and get its diagnostic stats library(ggplot2) data(cars) mod <- fortify(lm(speed ~ dist, data = cars)) attach(mod) str(mod) # Now I want to make sure the residuals are homoscedastic qplot (x = dist, y = .resid, data = mod) + geom_smooth(se = FALSE) # "se = FALSE" Removes the standard error bands But does anyone know how I can use ggplot2 and qplot to generate plots where the 0-line, "mean + 1sd" AND "mean - 1sd" lines would be superimposed? Is that a weird/complex question to be asking?

  • How do I abort a socket.recv() from another thread in python?

    - by Samuel Skånberg
    I have a main thread that waits for connection. It spawns client threads that will echo the response from the client (telnet in this case). But say that I want to close down all sockets and all threads after some time, like after 1 connection. How would I do? If I do clientSocket.close() from the main thread, it won't stop doing the recv. It will only stop if I first send something through telnet, then it will fail doing further sends and recvs. My code look like this: # Echo server program import socket from threading import Thread import time class ClientThread(Thread): def __init__(self, clientSocket): Thread.__init__(self) self.clientSocket = clientSocket def run(self): while 1: try: # It will hang here, even if I do close on the socket data = self.clientSocket.recv(1024) print "Got data: ", data self.clientSocket.send(data) except: break self.clientSocket.close() HOST = '' PORT = 6000 serverSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) serverSocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) serverSocket.bind((HOST, PORT)) serverSocket.listen(1) clientSocket, addr = serverSocket.accept() print 'Got a new connection from: ', addr clientThread = ClientThread(clientSocket) clientThread.start() time.sleep(1) # This won't make the recv in the clientThread to stop immediately, # nor will it generate an exception clientSocket.close()

  • Managing logs/warnings in Python extensions

    - by Dimitri Tcaciuc
    TL;DR version: What do you use for configurable (and preferably captured) logging inside your C++ bits in a Python project? Details follow. Say you have a a few compiled .so modules that may need to do some error checking and warn user of (partially) incorrect data. Currently I'm having a pretty simplistic setup where I'm using logging framework from Python code and log4cxx library from C/C++. log4cxx log level is defined in a file (log4cxx.properties) and is currently fixed and I'm thinking how to make it more flexible. Couple of choices that I see: One way to control it would be to have a module-wide configuration call. # foo/__init__.py import sys from _foo import import bar, baz, configure_log configure_log(sys.stdout, WARNING) # tests/test_foo.py def test_foo(): # Maybe a custom context to change the logfile for # the module and restore it at the end. with CaptureLog(foo) as log: assert foo.bar() == 5 assert log.read() == "124.24 - foo - INFO - Bar returning 5" Have every compiled function that does logging accept optional log parameters. # foo.c int bar(PyObject* x, PyObject* logfile, PyObject* loglevel) { LoggerPtr logger = default_logger("foo"); if (logfile != Py_None) logger = file_logger(logfile, loglevel); ... } # tests/test_foo.py def test_foo(): with TemporaryFile() as logfile: assert foo.bar(logfile=logfile, loglevel=DEBUG) == 5 assert logfile.read() == "124.24 - foo - INFO - Bar returning 5" Some other way? Second one seems to be somewhat cleaner, but it requires function signature alteration (or using kwargs and parsing them). First one is.. probably somewhat awkward but sets up entire module in one go and removes logic from each individual function. What are your thoughts on this? I'm all ears to alternative solutions as well. Thanks,

  • JUnit confusion: use 'extend Testcase' or '@Test' ?

    - by Rabarberski
    I've found the proper use (or at least the documentation) of JUnit very confusing. This question serves both as a future reference and as a real question. If I've understood correctly, there are two main approaches to create and run a JUnit test: Approach A: create a class that extends TestCase, and start test methods with the word test. When running the class as a JUnit Test (in Eclipse), all methods starting with the word test are automatically run. import junit.framework.TestCase; public class DummyTestA extends TestCase { public void testSum() { int a = 5; int b = 10; int result = a + b; assertEquals(15, result); } } Approach B: create a 'normal' class and prepend a @Test annotation to the method. Note that you do NOT have to start the method with the word test. import org.junit.*; import static org.junit.Assert.*; public class DummyTestB { @Test public void Sum() { int a = 5; int b = 10; int result = a + b; assertEquals(15, result); } } Mixing the two seems not to be a good idea, see e.g. this stackoverflow question: Now, my questions(s): What is the preferred approach, or when would you use one instead of the other? Approach B allows for testing for exceptions by extending the @Test annotation like in @Test(expected = ArithmeticException.class). But how do you test for exceptions when using approach A? When using approach A, you can group a number of test classes in a test suite. TestSuite suite = new TestSuite("All tests");<br/> suite.addTestSuite(DummyTestA.class); suite.addTestSuite(DummyTestAbis.class);` But this can't be used with approach B (since each testclass should subclass TestCase). What is the proper way to group tests for approach B?

  • Select those objects whose related objects IDs are *all* in given string

    - by Jannis
    Hi Django people, I want to build a frontend to a recipe database which enables the user to search for a list of recipes which are cookable with the ingredients the user supplies. I have the following models class Ingredient(models.Model): name = models.CharField(max_length=100, unique=True) slug = models.SlugField(max_length=100, unique=True) importancy = models.PositiveSmallIntegerField(default=4) […] class Amount(models.Model): recipe = models.ForeignKey('Recipe') ingredient = models.ForeignKey(Ingredient) […] class Rezept(models.Model): name = models.CharField(max_length=100) slug = models.SlugField() instructions = models.TextField() ingredients = models.ManyToManyField(Ingredient, through=Amount) […] and a rawquery which does exactly what I want: It gets all the recipes whose required ingredients are all contained in the list of strings that the user supplies. If he supplies more than necessary, it's fine too. query = "SELECT *, COUNT(amount.zutat_id) AS selected_count_ingredients, (SELECT COUNT(*) FROM amount WHERE amount.recipe_id = amount.id) AS count_ingredients FROM amount LEFT OUTER JOIN amount ON (recipe.id = recipe.recipe_id) WHERE amount.ingredient_id IN (%s) GROUP BY amount.id HAVING count_ingredient=selected_count_ingredient" % ",".join([str(ingredient.id) for ingredient in ingredients]) rezepte = Rezept.objects.raw(query) Now, what I'm looking for is a way that does not rely on .raw() as I would like to do it purely with Django's queryset methods. Additionally, it would be awesome if you guys knew a way of including the ingredient's importancy in the lookup so that a recipe is still shown as a result even though one of its ingredients (that has an importancy of 0) is not supplied by the user.

  • Where should I put contextual data related to an Object that is not really a property of the object?

    - by RenderIn
    I have a Car class. It has three properties: id, color and model. In a particular query I want to return all the cars and their properties, and I also want to return a true/false field called "searcherKnowsOwner" which is a field I calculate in my database query based on whether or not the individual conducting the search knows the owner. I have a database function that takes the ID of the searcher and the ID of the car and returns a boolean. My car class looks like this (pseudocode): class Car{ int id; Color color; Model model; } I have a screen where I want to display all the cars, but I also want to display a flag next to each car if the person viewing the page knows the owner of that car. Should I add a field to the Car class, a boolean searcherKnowsOwner? It's not a property of the car, but is actually a property of the user conducting the search. But this seems like the most efficient place to put this information.

  • m2eclipse: How to set Eclipse project settings when importing a maven project?

    - by Marius Andreiana
    Using m2eclipse Eclipse plugin, everybody on the dev team should be able to checkout source code, import Maven project in Eclipse and be good to go. I saw m2eclipse is being merged into Eclipse 3.7, and maven-eclipse-plugin won't be maintained any longer, so I'm looking for a m2eclipse-based solution (without running "mvn eclipse:clean eclipse:eclipse" before project import, which is what maven-eclipse-plugin does). maven-eclipse-plugin allows this in pom.xml <additionalConfig> <file> <name>.settings/com.google.gdt.eclipse.core.prefs</name> <content><![CDATA[ eclipse.preferences.version=2 jarsExcludedFromWebInfLib= warSrcDir=${project.build.directory}/${project.build.finalName} warSrcDirIsOutput=true ]]> </content> </file> The more general question is How would m2eclipse do something similar? For some cases, just saving the eclipse .settings/prefs file works (e.g. org.eclipse.jdt.ui.prefs), but in this case, com.google.gdt.eclipse.core.prefs is always overwritten on m2eclipse project import. A specific question is asked here, with no reply. Thanks! UPDATE: Not possible now, see request

  • How can I visualise a "broken" hierarchical dataset?

    I have a reasonably large datatable structured something like this: StaffNo Grade Direct Boss2 Boss3 Boss4 Boss5 Boss6 ------- ----- ----- ----- ----- ----- ----- ----- 10001 1 10002 10002 10057 10094 10043 10099 10002 2 10057 NULL 10057 10094 10043 10099 10003 1 10004 10004 10057 10094 10043 10099 10004 2 10057 NULL 10057 10094 10043 10099 10057 3 10094 NULL NULL 10094 10043 10099 etc.... i.e. a unique id , their level (grade) in the hierarchy, a record of their bosses ID and the IDs of the supervisors above. (The 2,3,4, etc refers to the boss at that particular grade). The system relies on a strict hierarchy - if you are my boss (/parent) then your boss must be my grandparent. Unfortunately this rule is not enforced within the data model and the data ultimately comes from other systems which don't even know about the rule, let alone observe it. So you and I may share the same boss, but our bosses boss won't be the same. note: I cannot change the data model I cannot fix the data at source. So (for the moment) I have to fix the data once it's in place. Once a fortnight someone will do something which breaks the model and I'll need to modify the procs slightly to resolve. Not ideal, but I'm stuck with this for the next six months. Anyway, specific queries are easy to produce but I find it hard to keep track of the bigger picutre. The application which sits on this runs without complaint regardless but navigating around the system becoming extraordinarily confusing. So my question is: Can anyone recommend a tool (or technique) for generating some kind of "broken tree" diagram in this sort of circumstances? I don't want something that will fix things for me, or attempt statistical analysis but at least something that will give a visual indication of how broken it is at any one time. Note : At the moment this is in a SQL Server database but I'm open to ideas utilising C#, Perl or Python.

  • Display pdf file inline in Rails app

    - by Martas
    Hi, I have a pdf file attachment saved in the cloud. The file is attached using attachment_fu. All I do to display it in the view is: <%= image_tag @model.pdf_attachment.public_filename %> When I load the page with this code in the browser, it does what I want: it displays the attached pdf file. But only on Mac. On Windows, browsers will display a broken image placeholder. Chrome's Developer Tools report: "Resource interpreted as image but transferred with MIME type application/pdf." I also tried sending the file from controller: in PdfAttachmentController: def send_pdf_attachment pdf_attachment = PdfAttachment.find params[:id] send_file pdf_attachment.public_filename, :type => pdf_attachment.content_type, :file_name => pdf_attachment.filename, :disposition => 'inline' end in routes.rb: map.send_pdf_attachment '/pdf_attachments/send_pdf_attachment/:id', :controller => 'pdf_attachments', :action => 'send_pdf_attachment' and in the view: <%= send_pdf_attachment_path @model.pdf_attachment %> or <%= image_tag( send_pdf_attachment_path @model.pdf_attachment ) %> And that doesn't display the file on Mac (I didn't try on Windows), it displays the path: pdf_attachments/send_pdf_attachment/35 So, my question is: what do I do to properly display a pdf file inline?

  • Method for defining simultaneous has-many and has-one associations between two models in CakePHP?

    - by Hobonium
    One thing with which I have long had problems, within the CakePHP framework, is defining simultaneous hasOne and hasMany relationships between two models. For example: BlogEntry hasMany Comment BlogEntry hasOne MostRecentComment (where MostRecentComment is the Comment with the most recent created field) Defining these relationships in the BlogEntry model properties is problematic. CakePHP's ORM implements a has-one relationship as an INNER JOIN, so as soon as there is more than one Comment, BlogEntry::find('all') calls return multiple results per BlogEntry. I've worked around these situations in the past in a few ways: Using a model callback (or, sometimes, even in the controller or view!), I've simulated a MostRecentComment with: $this->data['MostRecentComment'] = $this->data['Comment'][0]; This gets ugly fast if, say, I need to order the Comments any way other than by Comment.created. It also doesn't Cake's in-built pagination features to sort by MostRecentComment fields (e.g. sort BlogEntry results reverse-chronologically by MostRecentComment.created. Maintaining an additional foreign key, BlogEntry.most_recent_comment_id. This is annoying to maintain, and breaks Cake's ORM: the implication is BlogEntry belongsTo MostRecentComment. It works, but just looks...wrong. These solutions left much to be desired, so I sat down with this problem the other day, and worked on a better solution. I've posted my eventual solution below, but I'd be thrilled (and maybe just a little mortified) to discover there is some mind-blowingly simple solution that has escaped me this whole time. Or any other solution that meets my criteria: it must be able to sort by MostRecentComment fields at the Model::find level (ie. not just a massage of the results); it shouldn't require additional fields in the comments or blog_entries tables; it should respect the 'spirit' of the CakePHP ORM. (I'm also not sure the title of this question is as concise/informative as it could be.)

  • Flex fixed and variable height - can it be set in markup?

    - by Prutswonder
    I've got the following Flex application markup: <app:MyApplicationClass xmlns:app="*" width="100%" height="100%" layout="vertical" horizontalScrollPolicy="off" verticalScrollPolicy="off"> <mx:VBox id="idPageContainer" width="100%" height="100%" verticalGap="0" horizontalScrollPolicy="off" verticalScrollPolicy="off"> <mx:HBox id="idTopContainer" width="100%" height="28" horizontalGap="2"> (top menu stuff goes here) </mx:HBox> <mx:HBox id="idBottomContainer" width="100%" height="100%" verticalScrollPolicy="off" clipContent="false"> (page stuff goes here) </mx:HBox> </mx:VBox> </app:MyApplicationClass> When I run it, it displays top panel with a fixed height, and a bottom panel with variable height. I expect the bottom panel's height to contain the remaining height, but it somehow overflows off-page. The only way I found to fix this height issue (so far) is to programmatically set the height to be fixed instead of variable: <mx:HBox id="idBottomContainer" width="100%" height="700" verticalScrollPolicy="off" clipContent="false"> (page stuff goes here) </mx:HBox> And code-behind: package { import mx.containers.HBox; import mx.core.Application; import mx.events.ResizeEvent; // (...) public class MyApplicationClass extends Application { public var idBottomContainer:HBox; // (...) private function ON_CreationComplete (event:FlexEvent) : void { // (...) addEventListener(ResizeEvent.RESIZE, ON_Resize); } private function ON_Resize (event:Event) : void { idBottomContainer.height = this.height - idTopContainer.height; } } } But this solution is too "dirty" and I'm looking for a more elegant way. Does anyone know an alternative?

  • Am I mocking this helper function right in my Django test?

    - by CppLearner
    lib.py from django.core.urlresolvers import reverse def render_reverse(f, kwargs): """ kwargs is a dictionary, usually of the form {'args': [cbid]} """ return reverse(f, **kwargs) tests.py from lib import render_reverse, print_ls class LibTest(unittest.TestCase): def test_render_reverse_is_correct(self): #with patch('webclient.apps.codebundles.lib.reverse') as mock_reverse: with patch('django.core.urlresolvers.reverse') as mock_reverse: from lib import render_reverse mock_f = MagicMock(name='f', return_value='dummy_views') mock_kwargs = MagicMock(name='kwargs',return_value={'args':['123']}) mock_reverse.return_value = '/natrium/cb/details/123' response = render_reverse(mock_f(), mock_kwargs()) self.assertTrue('/natrium/cb/details/' in response) But instead, I get File "/var/lib/graphyte-webclient/graphyte-webenv/lib/python2.6/site-packages/django/core/urlresolvers.py", line 296, in reverse "arguments '%s' not found." % (lookup_view_s, args, kwargs)) NoReverseMatch: Reverse for 'dummy_readfile' with arguments '('123',)' and keyword arguments '{}' not found. Why is it calling reverse instead of my mock_reverse (it is looking up my urls.py!!) The author of Mock library Michael Foord did a video cast here (around 9:17), and in the example he passed the mock object request to the view function index. Furthermore, he patched POll and assigned an expected return value. Isn't that what I am doing here? I patched reverse? Thanks.

  • Dynamically setting the queryset of a ModelMultipleChoiceField to a custom recordset

    - by Daniel Quinn
    I've seen all the howtos about how you can set a ModelMultipleChoiceField to use a custom queryset and I've tried them and they work. However, they all use the same paradigm: the queryset is just a filtered list of the same objects. In my case, I'm trying to get the admin to draw a multiselect form that instead of using usernames as the text portion of the , I'd like to use the name field from my account class. Here's a breakdown of what I've got: # models.py class Account(models.Model): name = models.CharField(max_length=128,help_text="A display name that people understand") user = models.ForeignKey(User, unique=True) # Tied to the User class in settings.py class Organisation(models.Model): administrators = models.ManyToManyField(User) # admin.py from django.forms import ModelMultipleChoiceField from django.contrib.auth.models import User class OrganisationAdminForm(forms.ModelForm): def __init__(self, *args, **kwargs): from ethico.accounts.models import Account self.base_fields["administrators"] = ModelMultipleChoiceField( queryset=User.objects.all(), required=False ) super(OrganisationAdminForm, self).__init__(*args, **kwargs) class Meta: model = Organisation This works, however, I want queryset above to draw a selectbox with the Account.name property and the User.id property. This didn't work: queryset=Account.objects.all().order_by("name").values_list("user","name") It failed with this error: 'tuple' object has no attribute 'pk' I figured that this would be easy, but it's turned into hours of dead-ends. Anyone care to shed some light?
