  • android: How to set a listener that fires when my ViewFlipper shows a new child

    - by Joseph Cheek
    Hi Android gurus, I have a ViewFlipper for which I want a listener to fire when the child displayed is changed. I have set an OnFocusChangeListener to the ViewFlipper but it never fires when I flip from child 0 to child 1 or vice-versa. The ViewFlipper contains two RelativeLayouts and I have tried setting OnFocusChangeListeners for those but I get a ClassCastException when I try to set it. Here's my code: RelativeLayout songsLayout = (RelativeLayout) findViewById(R.id.song_page_layout); songsLayout.setOnFocusChangeListener(new OnFocusChangeListener() { public void onFocusChange(View view, boolean hasFocus) { showPopUp("View " + view.getId() + " now has focus: " + hasFocus); } } ); R.is.song_page_layout is one of my RelativeLayouts and showPopUp() is a function I use to show, well, popups. Does anyone have working code for some sort of trigger that fires when a ViewFlipper changes which child is displayed?

  • Avoiding first chance exception messages when the exception is safely handled

    - by CVertex
    The following bit of code catches the EOS Exception using (var reader = new BinaryReader(httpRequestBodyStream)) { try { while (true) { bodyByteList.Add(reader.ReadByte()); } } catch (EndOfStreamException) { } } So why do I still receive first-chance exceptions in my console? A first chance exception of type 'System.IO.EndOfStreamException' occurred in mscorlib.dll Is there a way to hide these first chance exception messages?

  • Tab bar controller inside a navigation controller, or sharing a navigation root view

    - by Daniel Dickison
    I'm trying to implement a UI structured like in the Tweetie app, which behaves as so: the top-level view controller seems to be a navigation controller, whose root view is an "Accounts" table view. If you click on any account, it goes to the second level, which has a tab bar across the bottom. Each tab item shows a different list and lets you drill down further (the subsequent levels don't show the tab bar). So, this seems like the implementation hierarchy is: UINavigationController Accounts: UITableViewController UITabBarController Tweets: UITableViewController Detail view of a tweet/user/etc Replies: UITableViewController ... This seems to work[^1], but appears to be unsupported according to the SDK documentation for -pushViewController:animated: (emphasis added): viewController: The view controller that is pushed onto the stack. It cannot be an instance of tab bar controller. I would like to avoid private APIs and the like, but I'm not sure why this usage is explicitly prohibited even when it seems to work fine. Anyone know the reason? I've thought about putting the tab bar controller as the main controller, with each of the tabs containing separate navigation controllers. The problem with this is that each nav controller needs to share a single root view controller (namely the "Accounts" table in Tweetie) -- this doesn't seem to work: pushing the table controller to a second nav controller seems to remove it from the first. Not to mention all the book-keeping when selecting a different account would probably be a pain. How should I implement this the Right Way? [^1]: The tab bar controller needs to be subclassed so that the tab bar controller's navigation item at that level stays in sync with the selected tab's navigation item, and the individual tab's table controller's need to push their respective detail views to self.tabBarController.navigationController instead of self.navigationController.

  • How to Use Firefox’s Web Developer Tools to View Website Structures in 3D

    - by Chris Hoffman
    Firefox 11 added two new web developer tools to Firefox’s already impressive arsenal. The Tilt feature visualizes website structures in 3D, while the Style Editor can edit CSS stylesheets on the fly. The 3D feature, known as Tilt, is a way of visualizing a website’s DOM. It integrates with the existing Document Inspector and uses WebGL to display rich 3D graphics in your browser.

  • Clear UIWebView content upon dismissal of modal view (iPhone OS 3.0)

    - by Ricky
    I currently have a UIWebView that is displayed within a modal view. It is basically a detail view that provides a view of a page when the user clicks a link. When the view is dismissed and then brought up again (when the user clicks another link), the previously-loaded content is still visible and the new content loads "on top" of the last content. This makes sense because the instance of the UIWebView persists between sessions and is only released when the memory is needed. However, I would like to completely clear the UIWebView when the modal view is dismissed so that 1) content is cleared and 2) memory is freed. Thus far my research and attempts have not found an answer. These links haven't worked for me: http://stackoverflow.com/questions/2184688/is-it-possible-to-free-memory-of-uiwebview http://stackoverflow.com/questions/2311564/reused-uiwebview-showing-previous-loaded-content-for-a-brief-second-on-iphone I've tried [[NSURLCache sharedURLCache] removeAllCachedResponses]; and setting the webView to nil and manually releasing the webView upon modal-view-dismiss to no avail. Any thoughts from the wizened masses?

  • didSelectRowAtIndexPath does not get called when scrolling and selecting a cell

    - by Falcon
    Hi all, It seems when I scroll my table view that if I select a cell while the table view is still scrolling, didSelectRowAtIndexPath doesn't get called. It works fine when the table view is still. Any ideas on why this might be? Also, is there a way that didSelectRowAtIndexPath can be called on press down? It seems it gets called after my finger/cursor is raised off of the cell. Thanks,

  • How do I add a button to my navigationController's right side after pushing another view controller

    - by bobobobo
    So, immediately after pushing a view controller to my tableView, // Override to support row selection in the table view. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here -- // for example, create and push another view controller. AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil]; [self.navigationController pushViewController:anotherViewController animated:YES]; Ok, so that makes another view slide on, and you can go back to the previous view ("pop" the current view) by clicking the button that automatically appears in the top left corner of the navigation bar now. Ok, so SAY I want to populate the RIGHT SIDE of the navigation bar with a DONE button, like in the "Notes" app that comes with the iPhone. How would I do that? I tried code like this: UIBarButtonItem * doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector( doneFunc ) ]; self.navigationController.navigationItem.rightBarButtonItem = doneButton ; // not it.. [doneButton release] ; doneFunc is defined, and everything, just the button never appears on the right side..

  • Postback event not firing on FIRST button click..

    - by ClarkeyBoy
    Hi, I have a form which accepts two arguments. The first one is mode - this is either view, new or edit. If it is new then the second argument is type - this is either range, collection or design. When set to new, and the type is valid, a new instance of that type is created and the data from the form is added to it. The item (range, collection or design) then validates the data. If any of the data is invalid then it throws an error, and this error is displayed at the top of the form telling the user why it is invalid. A variable, _Databind, is set to false so that it does not change the data input by the user (in the form fields). The button used to submit the button is called btnSave, and is created in the html source. The click event is wired up in the form Protected Sub Blah(sender, e) Handles btnSave.Click. Strangely, whenever I edit an item that already exists the form submits fine the first time - the click event is fired. However when in "new" mode I have to click the button twice to fire the event. It also blanks all the form fields out on first click. I have even put a Response.Write("Hello World") line at the start of the click event - this is not being output on first click when adding a new item either. It is on first load when the mode is set to edit however. Does anyone have any ideas as to what is causing it to behave this way? Thanks in advance for any help. Regards, Richard

  • Coupling between controller and view

    - by cheez
    The litmus test for me for a good MVC implementation is how easy it is to swap out the view. I've always done this really badly due to being lazy but now I want to do it right. This is in C++ but it should apply equally to non-desktop applications, if I am to believe the hype. Here is one example: the application controller has to check some URL for existence in the background. It may connect to the "URL available" event (using Boost Signals) as follows: BackgroundUrlCheckerThread(Controller & controller) { // ... signalUrlAvailable.connect( boost::bind(&Controller::urlAvailable,&controller,_1)) } So what does Controller::urlAvailable look like? Here is one possibility: void Controller::urlAvailable(Url url) { if(!view->askUser("URL available, wanna download it?")) return; else // Download the url in a new thread, repeat } This, to me, seems like a gross coupling of the view and the controller. Such a coupling makes it impossible to implement the view when using the web (coroutines aside.) Another possibility: void Controller::urlAvailable(Url url) { urlAvailableSignal(url); // Now, any view interested can do what it wants } I'm partial to the latter but it appears that if I do this there will be: 40 billion such signals. The application controller can get huge for a non-trivial application A very real possibility that a given view accidentally ignores some signals (APIs can inform you at link-time, but signals/slots are run-time) Thanks in advance.

  • Subview Doesnt AutoSize When Added to Root View Controller

    - by Per
    Hello, I have a root view controller that will have up to 10 or so subviews. I am implementing autorotation/autosize accross the entire app. My problem is this: - When I allocate all the view controllers and add each as a subview to the root controller during startup, everything works as it should. The only problem is that each view controller needs time to initialize. This causes my application to load very slowly. Instead I am trying to allocate the view controllers as they are required. Now I find that if the application goes into Landscape, and I allocate a view controller that is designed in portrait, it will autorotate but the autosize doesnt happen. In other words as soon as the subview is added to the root controller in portrait mode it rotates and sizes correctly (and stays that way). If the subview is added when the root controller is in landscape it rotates but doesnt autosize (and view sizes remain messed up rotating back to portrait) I have tried to force an autosize by calling SetNeedsLayout, SetNeedsDisplay, and LayoutIfNeeded but nothing works. I know i could probably do this manually by determining the root controllers orientation and resizing the subviews appropriately, but this is a lot of work for something that should work automatically. Am I missing something? Any help would be appreciated. My project is an iPad port from an iPhone app, the iPhone app doesnt rotate so Im not sure if this may be something wrong with the 3.2 beta.

  • is it a bad practice to call a View from another View in MVC?

    - by marcos.borunda
    I have some plain Views, they don't have any logic behind them (there is no action or controller behind them), their only propouse is to alert the user about something like "We have sent you an email to confirm your account", "You have no access to this resource", etc... These views are really simple, and calling them through a Controller/Action seems to be too much overhead, but somehow I feel like it is not quite correct. What do you think? How do you handle this kind of situations?? I guess this question will apply to any MVC Framework, but in my case I'm using the ASP.NET MVC 3 framework.

  • How To View and Write To System Log Files on Ubuntu

    - by Chris Hoffman
    Linux logs a large amount of events to the disk, where they’re mostly stored in the /var/log directory in plain text. Most log entries go through the system logging daemon, syslogd, and are written to the system log. Ubuntu includes a number of ways of viewing these logs, either graphically or from the command-line. You can also write your own log messages to the system log — particularly useful in scripts.

  • iPhone: addAnnotation not working when called from another view

    - by Nic Hubbard
    I have two views, the first view has an MKMapView on it named ridesMap. The second view is just a view with a UITableView in it. When you click the save button in the second view, it calls a method from the first view: // Get my first views class MyRidesMapViewController *rideMapView = [[MyRidesMapViewController alloc] init]; // Call the method from my first views class that removes an annotation [rideMapView addAnno:newRidePlacemark.coordinate withTitle:rideTitle.text withSubTitle:address]; This correctly calls the addAnno method, which looks like: - (void)addAnno:(CLLocationCoordinate2D)anno withTitle:(NSString *)annoTitle withSubTitle:(NSString *)subTitle { Annotation *ano = [[[Annotation alloc] init] autorelease]; ano.coordinate = anno; ano.title = annoTitle; ano.subtitle = subTitle; if ([ano conformsToProtocol:@protocol(MKAnnotation)]) { NSLog(@"YES IT DOES!!!"); } [ridesMap addAnnotation:ano]; }//end addAnno This method creates an annotation which does conform to MKAnnotation, and it suppose to add that annotation to the map using the addAnnotation method. But, the annotation never gets added. I NEVER get any errors when the annotation does not get added. But it never appears when the method is called. Why would this be? It seems that I have done everything correctly, and that I am passing a correct MKAnnotation to the addAnnotation method. So, I don't get why it never drops a pin? Could it be because I am calling this method from another view? Why would that matter?

  • Edit first column of GridView

    - by nCdy
    I've got very dynamic GridView and I need to allow to user to edit first column of it. After he edit first column of grid it must be updated on DataBase. Is there any ways to handle it ? My only idea is to put some changeable element to first cell of each Row so it must be able to set / get my values for each row but can't find yet any examples of it ... Additional info : GridView takes data from Object data source and all columns are dynamic (yes, maybe except first, but I add it in dynamic way) and load complete DataTable...

  • SQL Where Clause Against View

    - by Adam Carr
    I have a view (actually, it's a table valued function, but the observed behavior is the same in both) that inner joins and left outer joins several other tables. When I query this view with a where clause similar to SELECT * FROM [v_MyView] WHERE [Name] like '%Doe, John%' ... the query is very slow, but if I do the following... SELECT * FROM [v_MyView] WHERE [ID] in ( SELECT [ID] FROM [v_MyView] WHERE [Name] like '%Doe, John%' ) it is MUCH faster. The first query is taking at least 2 minutes to return, if not longer where the second query will return in less than 5 seconds. Any suggestions on how I can improve this? If I run the whole command as one SQL statement (without the use of a view) it is very fast as well. I believe this result is because of how a view should behave as a table in that if a view has OUTER JOINS, GROUP BYS or TOP ##, if the where clause was interpreted prior to vs after the execution of the view, the results could differ. My question is why wouldn't SQL optimize my first query to something as efficient as my second query?

  • How to mount nexus 7 file system to view files from command line

    - by knotech
    Just got a Nexus 7, switched MTP on and plugged it in. It pops right up in nautilus, is titled Nexus 7, and lets me browse all of the files. However, on the command line, it's simply listed as /media/usbdrive and when I try to list the files, nothing comes up. Do I have to manually mount it in order to navigate the files from the command line? And why is it that nautilus recognizes it, and has access immediately, but I can't get at it from the command line?

  • SparkViewEngine, RenderAction and Areas with ASP MVC 2 Beta?!

    - by scooby37
    I just ran into trouble with the AreaDescriptionFilter of Spark using MVC 2 Beta. The following line is from my Application.spark file. It results in the view engine looking in all possible locations of the view - except in the folders of the area "Shell". # Html.RenderAction("ShowMainMenu", "Navigation", new { area = "Shell" }); Running the same action using http://localhost/Shell/Navigation/ShowMainMenu executes fine and recognizes the area's view directory as expected. Any ideas how to fix this?

  • tail-like view on HTML logfiles

    - by h0b0
    I'm working on an application that creates HTML log files. I'm tired of having to manually reload and scroll to the bottom in the browser to see the latest entries. A solution that does not really satisfy me is using the Firefox plugins ReloadEvery and ScrollyFox. In many situations reloading frequency and scrolling speed are just to slow. Of course I could actually use tail, but I would prefer a rendered HTML page. Do you have any suggestions? Firefox extensions are preferred, but any other tip is appreciated, too.

  • Camera changes view when controller connected

    - by ChocoMan
    I have a weird situation. I have a model set to 0 for X,Y and Z. My camera's position is set to: 0 (X-value, but updates when the model moves around) the model's height + 20f (about the same level as the model's shoulders) 25f (behind the model) Without the controller plugged in, everything looks fine as I want it. But as soon as I plug the controller in, the camera aims to the sky! But when I unplug the controller, the camera is back to what it should be. Does anyone have any insight as to what may cause this from plugging a controller in?
