  • Get updated size of QGraphicsView

    - by onurozcelik
    Hi, In my Qt Application I am dynamically creating QGraphicsView(s) and adding them inside a QGridLayout. When I add first view inside grid, the view covers all the available space inside grid. Then I add second view and there are now two equally sized views inside grid. Then I add third view and there are now three equally sized views inside grid. And so on. How can I get updated size of first view? Below is my trial but I think this is not working. //Definition of viewsPerRow static const int viewsPerRow = 3; void window::newViewRequested() { QGraphicsView *view = new QGraphicsView; view->setVisible(true); viewVector.push_back(view); for(int i = viewGrid->count(); i < viewVector.count(); i++) { viewGrid->addWidget(view,i / viewsPerRow ,i % viewsPerRow); } qDebug()<<viewGrid->cellRect(0,0); }

  • 3.1.3 and 3.2 different behaviour

    - by teo
    I'm using a custom cell in tableView with a UITextField - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease]; UITextField *txtField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 280, 24)]; txtField.placeholder = @"<Enter Text>"; txtField.textAlignment = UITextAlignmentLeft; txtField.clearButtonMode = UITextFieldViewModeAlways; txtField.autocapitalizationType = UITextAutocapitalizationTypeNone; txtField.autocorrectionType = UITextAutocorrectionTypeNo; [cell.contentView addSubview:txtField]; [txtField release]; } } This works fine and the UITextField covers the cell. When i run this with 3.2 sdk or on the iPad the UITextField isn't aligned properly to the left, overlapping the cell and i have to use a UITextField width of 270 instead of 280 UITextField *txtField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 270, 24)]; It seems something is wrong the pixel ratio. How can this be fixed? Is there a way to determine the version of os the device has ( 3.1.2, 3.1.3, 3.2 or maybe even the 4.0) or can it be done another way? Thank you Teo

  • Binding a null variable in a PreparedStatement

    - by Paul Tomblin
    I swear this used to work, but it's not in this case. I'm trying to match col1, col2 and col3, even if one or more of them is null. I know that in some languages I've had to resort to circumlocutions like ((? is null AND col1 is null) OR col1 = ?). Is that required here? PreparedStatement selStmt = getConn().prepareStatement( "SELECT * " + "FROM tbl1 " + "WHERE col1 = ? AND col2 = ? and col3 = ?"); try { int col = 1; setInt(selStmt, col++, col1); setInt(selStmt, col++, col2); setInt(selStmt, col++, col3); ResultSet rs = selStmt.executeQuery(); try { while (rs.next()) { // process row } } finally { rs.close(); } } finally { selStmt.close(); } // Does the equivalient of stmt.setInt(col, i) but preserves nullness. protected static void setInt(PreparedStatement stmt, int col, Integer i) throws SQLException { if (i == null) stmt.setNull(col, java.sql.Types.INTEGER); else stmt.setInt(col, i); }

  • Threading.Timer invokes asynchronously many methods

    - by Dimitar
    Hi guys! Please help! I call a threading.timer from global.asax which invokes many methods each of which gets data from different services and writes it to files. My question is how do i make the methods to be invoked on a regular basis let's say 5 mins? What i do is: in Global.asax I declare a timer protected void Application_Start() { TimerCallback timerDelegate = new TimerCallback(myMainMethod); Timer mytimer = new Timer(timerDelegate, null, 0, 300000); Application.Add("timer", mytimer); } the declaration of myMainMethod looks like this: public static void myMainMethod(object obj) { MyDelegateType d1 = new MyDelegateType(getandwriteServiceData1); d1.BeginInvoke(null, null); MyDelegateType d2 = new MyDelegateType(getandwriteServiceData2); d2.BeginInvoke(null, null); } this approach works fine but it invokes myMainMethod every 5 mins. What I need is the method to be invoked 5 mins after all the data is retreaved and written to files on the server. How do I do that?

  • what makes a Tomcat5.5 cannot be "aware" of new Java Web Applications?

    - by Michael Mao
    This is for uni homework, but I reckon it is more a generic problem to the Tomcat Server(version 5.5.27) on my uni. The problem is, I first did a skeleton Java Web Application (Just a simple Servlet and a welcome-file, nothing complicated, no lib included) using NetBeans 6.8 with the bundled Tomcat 6.0.20 (localhost:8084/WSD) Then, to test and prove it is "portable" and "auto-deploy-able", I cleaned and built a WSD.war file and dropped it onto my Xampp Tomcat (localhost:8080/WSD). The war extracted everything accordingly and I can see identical output from this Tomcat. So far, so good. However, after I tried to drop to war onto uni server, funny thing happens: uni server Even though I've changed the war permission to 755, it is simply not "responding". I then copied the extracted files to uni server, the MainServlet cannot be recognized from within its Context Path "/WSD", basically nothing works, expect the static index.jsp. I tried several times to stop and restart uni Tomcat, it doesn't help? I wonder what makes this happen? Is there anything I did wrong with my approach? To be frank I paid no attention to a server not under my control, and I am unfortunately not a real active day-to-day Java Programmer now. I understand the fundamentals of MVC, Servelets, JSPs, JavaBeans, but I really feel frustrated by this, as I cannot see why... Or, should I ask, a Java Web Application, after cleaned and built by NetBeans6.8, is self-contained and self-configured so ready to be deployed to any Java Web Container? I know, I can certainly program everything in plain old JSP, but this is soooo... unacceptable to myself... Update : I am now wondering if there is any free Tomcat Hosting so that I would like to see if my war file and/or my web app can go with them without any configuration at all?

  • Same code, not the same place, different results

    - by Tom
    Hi! I'm trying to something pretty simple but I don't understand why the second bit of code is giving me a bad access error... First: - (UITableViewCell *)tableView:tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } // Tom: Converting the row int to a string and adding 1 to it so that the rows fit with the array indexes.) NSString *key = [NSString stringWithFormat:@"%d", indexPath.row+1]; NSArray *array = [self.tableDataSource objectForKey:key]; NSLog(@"%@", key); NSLog(@"%@", [array description]); cell.textLabel.text = [array objectAtIndex:1]; return cell; } That code gives me exactly what I want: 2010-03-18 15:18:12.884 PremierSoins[28005:40b] 1 2010-03-18 15:18:12.885 PremierSoins[28005:40b] ( 7, Blessures ) 2010-03-18 15:18:12.892 PremierSoins[28005:40b] 2 2010-03-18 15:18:12.893 PremierSoins[28005:40b] ( 18, "Test 2" ) But then, the second: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSString *key = [NSString stringWithFormat:@"%d", indexPath.row+1]; NSArray *array = [self.tableDataSource objectForKey:key]; NSLog(@"%@", key); NSLog(@"%@", [array description]); } Is only able to get me the key, but the description of the array makes it crash... tableDataSource is a NSMutableDictionary containing multiple arrays... Like this: { 1 = ( 7, Blessures ); 2 = ( 18, "Test 2" ); } Do you have any clue? I've been looking at this since yesterday... Thanks! Tom

  • Inereritance of clousure objects and overriding of methods

    - by bobikk
    I need to extend a class, which is encapsulated in a closure. This base class is following: var PageController = (function(){ // private static variable var _current_view; return function(request, new_view) { ... // priveleged public function, which has access to the _current_view this.execute = function() { alert("PageController::execute"); } } })();` Inheritance is realised using the following function: function extend(subClass, superClass){ var F = function(){ }; F.prototype = superClass.prototype; subClass.prototype = new F(); subClass.prototype.constructor = subClass; subClass.superclass = superClass.prototype; StartController.cache = ''; if (superClass.prototype.constructor == Object.prototype.constructor) { superClass.prototype.constructor = superClass; } } I subclass the PageController: var StartController = function(request){ // calling the constructor of the super class StartController.superclass.constructor.call(this, request, 'start-view'); } // extending the objects extend(StartController, PageController); // overriding the PageController::execute StartController.prototype.execute = function() { alert('StartController::execute'); } Inheritance is working. I can call every PageController's method from StartController's instance. However, method overriding doesn't work: var startCont = new StartController(); startCont.execute(); alerts "PageController::execute". How should I override this method?

  • Apache/Rails/Passenger directory URLs that don't end in '/' fail to 404.

    - by Portamento
    I'm using Apache with passenger to run a rails app. In my rails app, I have some static content in subdirectories of the public directory. Each subdirectory has an index.html in it. So, inside the public directory, I have a subdir called 'b' and inside it, is an index.html. So it's like this: /public/b/index.html I have links to these pages, of the form: http://a.com/b If I do this in my regular non-rails web directory, Apache correctly rewrites this URL to be http://a.com/b/ which then, subsequently shows the index.html. It's only when accessing my rails app that it doesn't work. In fact, if I turn off passenger mod... so it just accesses my rails app like a regular document root, it works correctly also. What the heck do I need to do to get this to work properly with passenger? Again, it works fine in apache itself when passenger is not involved. I am running passenger 2.1.3. I have another server running passenger 2.0 that doesn't seem to have this problem, but I don't see anything different in the config other than the different versions of passenger itself. HELP! Been working on this for two days solid with no improvement!

  • Using memcache together with conventional cache

    - by Industrial
    Hi! Here's the deal. We would have taken the complete static html road to solve performance issues, but since the site will be partially dynamic, this won't work out for us. What we have thought of instead is using memcache + eAccelerator to speed up PHP and take care of caching for the most used data. Here's our two approaches that we have thought of right now: Using memcache on all<< major queries and leaving it alone to do what it does best. Usinc memcache for most commonly retrieved data, and combining with a standard harddrive-stored cache for further usage. The major advantage of only using memcache is of course the performance, but as users increases, the memory usage gets heavy. Combining the two sounds like a more natural approach to us, even though the theoretical compromize in performance. Memcached appears to have some replication features available as well, which may come handy when it's time to increase the nodes. What approach should we use? - Is it stupid to compromize and combine the two methods? Should we insted be focusing on utilizing memcache and instead focusing on upgrading the memory as the load increases with the number of users? Thanks a lot!

  • Wrapper Classes for Backward compatibility in Java

    - by Casebash
    There is an interesting article here on maintaing backwards compatibility for Java. In the wrapper class section, I can't actually understand what the wrapper class accomplishes. In the following code from MyApp, WrapNewClass.checkAvailable() could be replaced by Class.forName("NewClass"). static { try { WrapNewClass.checkAvailable(); mNewClassAvailable = true; } catch (Throwable ex) { mNewClassAvailable = false; } } Consider when NewClass is unavailable. In the code where we use the wrapper (see below), all we have done is replace a class that doesn't exist, with one that exists, but which can't be compiled as it uses a class that doesn't exist. public void diddle() { if (mNewClassAvailable) { WrapNewClass.setGlobalDiv(4); WrapNewClass wnc = new WrapNewClass(40); System.out.println("newer API is available - " + wnc.doStuff(10)); }else { System.out.println("newer API not available"); } } Can anyone explain why this makes a difference? I assume it has something to do with how Java compiles code - which I don't know much about.

  • Third party multipart request in playframework

    - by Brian
    I'm making an application to post photos to yfrog and twitpic and I am having a little trouble figuring out how to set the parameters. Here is my code: public static Result index() { HttpClient httpclient = new DefaultHttpClient(); WSRequestHolder holder = WS.url("http://api.twitpic.com/2/upload.json"); holder.setHeader("Authorization", ""); return async(holder.post("").map(new Function<WS.Response, Result>() { public Result apply(WS.Response response) { return ok(response.getBody()); } })); } Now, I don't expect this to actually get an ok response from the server, as I am just testing the responses that I get back from the server, and that is one that says I need to provide the api key. I figured as much, but I'm not sure of the syntax for providing that parameter, as I need to also give the name of the file and the file. I tried setting holder.post("key=somekey"), with the hope that I would get a different error message (like the key you provided is invalid) but I just get the same error. I'm assuming that I probably need to send it in the for of a multipart request, but I am not very experienced with this kind of request and can't find any play documentation on how to create a multipart request, other than in an html form. Any suggestions and help will be much appreciated. And fyi, I do know that there are yfrog and twitpic java classes to handle this kind of stuff, but I want to do it myself, more so for learning how to do this kind of stuff. Thanks in advance!

  • Compiling code at runtime, loading into current appdomain.

    - by Richard Friend
    Hi Im compiling some code at runtime then loading the assembly into the current appdomain, however when i then try to do Type.GetType it cant find the type... Here is how i compile the code... public static Assembly CompileCode(string code) { Microsoft.CSharp.CSharpCodeProvider provider = new CSharpCodeProvider(); ICodeCompiler compiler = provider.CreateCompiler(); CompilerParameters compilerparams = new CompilerParameters(); compilerparams.GenerateExecutable = false; compilerparams.GenerateInMemory = false; foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies()) { try { string location = assembly.Location; if (!String.IsNullOrEmpty(location)) { compilerparams.ReferencedAssemblies.Add(location); } } catch (NotSupportedException) { // this happens for dynamic assemblies, so just ignore it. } } CompilerResults results = compiler.CompileAssemblyFromSource(compilerparams, code); if (results.Errors.HasErrors) { StringBuilder errors = new StringBuilder("Compiler Errors :\r\n"); foreach (CompilerError error in results.Errors) { errors.AppendFormat("Line {0},{1}\t: {2}\n", error.Line, error.Column, error.ErrorText); } throw new Exception(errors.ToString()); } else { AppDomain.CurrentDomain.Load(results.CompiledAssembly.GetName()); return results.CompiledAssembly; } } This bit fails after getting the type from the compiled assembly just fine, it does not seem to be able to find it using Type.GetType.... Assembly assem = RuntimeCodeCompiler.CompileCode(code); string typeName = String.Format("Peverel.AppFramework.Web.GenCode.ObjectDataSourceProxy_{0}", safeTypeName); Type t = assem.GetType(typeName); //This works just fine.. Type doesntWork = Type.GetType(t.AssemblyQualifiedName); Type doesntWork2 = Type.GetType(t.Name); ....

  • Setting the default stack size on Linux globally for the program

    - by wowus
    So I've noticed that the default stack size for threads on linux is 8MB (if I'm wrong, PLEASE correct me), and, incidentally, 1MB on Windows. This is quite bad for my application, as on a 4-core processor that means 64 MB is space is used JUST for threads! The worst part is, I'm never using more than 100kb of stack per thread (I abuse the heap a LOT ;)). My solution right now is to limit the stack size of threads. However, I have no idea how to do this portably. Just for context, I'm using Boost.Thread for my threading needs. I'm okay with a little bit of #ifdef hell, but I'd like to know how to do it easily first. Basically, I want something like this (where windows_* is linked on windows builds, and posix_* is linked under linux builds) // windows_stack_limiter.c int limit_stack_size() { // Windows impl. return 0; } // posix_stack_limiter.c int limit_stack_size() { // Linux impl. return 0; } // stack_limiter.cpp int limit_stack_size(); static volatile int placeholder = limit_stack_size(); How do I flesh out those functions? Or, alternatively, am I just doing this entirely wrong? Remember I have no control over the actual thread creation (no new params to CreateThread on Windows), as I'm using Boost.Thread.

  • Unit Testing-- fundamental goal?

    - by David
    Me and my co-workers had a bit of a disagreement last night about unit testing in our PHP/MySQL application. Half of us argued that when unit testing a function within a class, you should mock everything outside of that class and its parents. The other half of us argued that you SHOULDN'T mock anything that is a direct dependancy of the class either. The specific example was our logging mechanism, which happened through a static Logging class, and we had a number of Logging::log() calls in various locations throughout our application. The first half of us said the Logging mechanism should be faked (mocked) because it would be tested in the Logging unit tests. The second half of us argued that we should include the original Logging class in our unit test so that if we make a change to our logging interface, we'll be able to see if it creates problems in other parts of the application due to failing to update the call interface. So I guess the fundamental question is-- do unit tests serve to test the functionality of a single unit in a closed environment, or show the consequences of changes to a single unit in a larger environment? If it's one of these, how do you accomplish the other?

  • .Net 2.0 ServiceController.GetServices()

    - by Miles
    I've got a website that has windows authentication enable on it. From a page in the website, the users have the ability to start a service that does some stuff with the database. It works fine for me to start the service because I'm a local admin on the server. But I just had a user test it and they can't get the service started. My question is: Does anyone know of a way to get a list of services on a specified computer by name using a different windows account than the one they are currently logged in with? I really don't want to add all the users that need to start the service into a windows group and set them all to a local admin on my IIS server..... Here's some of the code I've got: public static ServiceControllerStatus FindService() { ServiceControllerStatus status = ServiceControllerStatus.Stopped; try { string machineName = ConfigurationManager.AppSettings["ServiceMachineName"]; ServiceController[] services = ServiceController.GetServices(machineName); string serviceName = ConfigurationManager.AppSettings["ServiceName"].ToLower(); foreach (ServiceController service in services) { if (service.ServiceName.ToLower() == serviceName) { status = service.Status; break; } } } catch(Exception ex) { status = ServiceControllerStatus.Stopped; SaveError(ex, "Utilities - FindService()"); } return status; } My exception comes from the second line in the try block. Here's the error: System.InvalidOperationException: Cannot open Service Control Manager on computer 'server.domain.com'.

  • Cannot call DLL import entry in C# from C++ project. EntryPointNotFoundException

  • nginx multiple domain virtual host configuration

    - by Poe
    I'm setting up nginx with multiple domain or wildcard support for convenience sake, rather than setting up 50+ different sites-available/* files. Hopefully this is enough to show you what I'm trying to do. Some are static sites, some are dynamic with usually wordpress installed. If an index.php exists, everything works as expected. If a file is requested that does not exist (missing.html), a 500 error is given due to the rewrite. The logged error is: *112 rewrite or internal redirection cycle while processing "/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/index.php/missing.html" The basic nginx configuration I'm currently using is: ` listen 80 default; server _; ... location / { root /var/www/$host; if (-f $request_filename) { expires max; break; } # problem, what if index.php does not exist? if (!-e $request_filename) { rewrite ^/(.*)$ /index.php/$1 last; } } ... ` If an index.php does not exist, and the file also does not exist, I would like it to error 404. Currently, nginx does not support multiple condition if's or nested if so I need a workaround.

NSString *messagelevel1 = @"45"; NSString *messagelevel = @"1"; NSString *HuidigLevel = messagelevel; NSDecimalNumber *huidigleveldec = [[NSDecimalNumber alloc] initWithString: HuidigLevel]; float HuidigLevelRek = [huidigleveldec floatValue]; //HERE IS THE PROBLEM NSString* LevelTotaal=[[NSString alloc] initWithFormat:@"messagelevel%.f",HuidigLevelRek]; NSString*result = LevelTotaal; NSLog(@"%@",result); // THIS RESULT SHOULD RETURN THE SAME VALUE AS THE LINE UNDER THIS LINE! NSLog(@"%@",messagelevel1); I want the *result string behaves like the *huidiglevel string and fetch some information, but because the LevelTotaal is a NSString, It doesn't fetch this information. I really got no idea where to google for this problem, searching the Developer docs didn't helped either . Maybe you guys can help me out? Actually the second NSLog returns the value and to first NSLog just returns messagelevel1. To tell you in short ;) I hope you guys get what I'm saying!

  • How to implement generic callbacks in C++

    - by Kylotan
    Forgive my ignorance in asking this basic question but I've become so used to using Python where this sort of thing is trivial that I've completely forgotten how I would attempt this in C++. I want to be able to pass a callback to a function that performs a slow process in the background, and have it called later when the process is complete. This callback could be a free function, a static function, or a member function. I'd also like to be able to inject some arbitrary arguments in there for context. (ie. Implementing a very poor man's coroutine, in a way.) On top of that, this function will always take a std::string, which is the output of the process. I don't mind if the position of this argument in the final callback parameter list is fixed. I get the feeling that the answer will involve boost::bind and boost::function but I can't work out the precise invocations that would be necessary in order to create arbitrary callables (while currying them to just take a single string), store them in the background process, and invoke the callable correctly with the string parameter.

  • Android, phone call audio stream via wlan

    - by moppel
    I am planning on developing my specific voip app for android. Here's the scenario: when a phone call occurs I want to hear the person who's calling on my local pc speakers and I want to speak to him via my own pc microphone / headset. So I need to send the audio stream of both me and the person I am talking to via the wlan network. Something like this: ... onCallStateChanged(int state, String phoneNumber){ while(state == PhoneListener.CALL_STATE_OFFHOOK){ //while phone call is happaning //send incoming speech via wlan to pc //receive audiostream from pc microphone and direct it to the phone call } } ... Is this possible with the current Android API? (Actually it should be since voip apps are available in the market) I did some research in the Android API and all I found was the AudioManager which has constant named public static final int STREAM_VOICE_CALL; //The audio stream for phone calls But I don't know how to use it our how it should give me access to the actual audiostreams which I can send via network. How do I manage to do this? The connection would be realised by TCP sockets.

  • UITableView with Custom Cell only loads one row of data at a time

    - by Anton
    For my table, I've created a custom cell that has two labels. I also have two arrays with data, that I use to respectively assign each label in the cell. My problem, is that when the table is viewed, only the first row has data, and the rest of the data "sorta" loads when I start scrolling down. By "sorta", only the first row will load at a time. The only time I get to see all the data, is when I scroll to the bottom, then scroll up again. I've used the cellForRowAtIndexPath method to load the data into my cell. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CustomCellIdentifier = @"CustomCellIdentifier"; CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:CustomCellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[CustomCell class]]) cell = (CustomCell *)oneObject; } NSUInteger row = [indexPath row]; //I have two tables to fill up, hence the tag if statement if ([tableView tag] == 0) { cell.arriveTimeLabel.text = [homeBoundTimes objectAtIndex:row]; cell.departTimeLabel.text = [homeBoundTimes objectAtIndex:row]; } else if ([tableView tag] == 1) { cell.arriveTimeLabel.text = [workBoundTimes objectAtIndex:row]; cell.departTimeLabel.text = [workBoundTimes objectAtIndex:row]; } return cell; } Is it possible that its only getting called when the top cell is being called?
