• How do CSS sprites work?

  - by Rachel

  I have 3 different images and want to create a sprite using CSS. I understand that will reduce HTTP requests. However, I am totally new to this concept and have no idea as to how to approach this. What would be best bet for me? Also I have seen there are some CSS sprite generators where you submit a .zip of images and it combines them. I tried doing that, but did not understood what was happening. Any guidance regarding creating and using CSS sprites would be highly appreciated. Update: I have gone through the A List Part article but it was not very clear to me. Can someone provide an example of using a CSS sprite? [A short, self-contained example in an answer is preferable for SO than just a link to an example elsewhere. –ed.]

• Rails: creating a custom data type / creating a shorthand

  - by Shyam

  Hi, I am wondering how I could create a custom data type to use within the rake migration file. Example: if you would be creating a model, inside the migration file you can add columns. It could look like this: def self.up create_table :products do |t| t.column :name, :string t.timestamps end end I would like to know how to create something like this: t.column :name, :my_custom_data_type The reason for this to create for example a "currency" type, which is nothing more than a decimal with a precision of 8 and a scale of 2. Since I use only MySQL, the solution for this database is sufficient enough. Thank you for your feedback and comments!

• Get Taskbar's Battery and PhoneSignal indicators icons and draw into a picturebox (C#/WindowsMobile)

  - by Christian Almeida

  Hi, Is there any way to get taskbar's battery and phonesignal indicators icons and then draw into a picturebox or something? Why do I need this? I need all screen space available, so all forms are maximized and they cover up the windowsmobile taskbar. But, I have to display information about battery e phone signal strength in just a couple of forms. I know how to get their values (like systeminformation.phonesignalstrength), but what I want is the "current icon", so I don't need to worry about their values. It's just a visual information for the user. In last case, if this is not possible, how to get those icons from windowsmobile shell, so I'll draw them by my self, treating each differente status/values that they assume. (This is what I don't want to do!) Thanks in advance and sorry for my poor english.

• How can I prompt for input using Selenium/Webdriver and use the result?

  - by Tempus

  I would like to allow for user input and make some decisions based on it. If I do this: driver.execute_script("prompt('Enter smth','smth')") I get a nice prompt, but I cannot use it's value. Is there any way of showing an input box to the user, and use the value typed there? EDIT: This is my script: from selenium.webdriver import Firefox if __name__ == "__main__": driver = Firefox() driver.execute_script("window.promptResponse=prompt('Enter smth','smth')") a = driver.execute_script("var win = this.browserbot.getUserWindow(); return win.promptResponse") print "got back %s" % a And this exits with the following exception: a = driver.execute_script("var win = this.browserbot.getUserWindow(); return win.promptResponse") File "c:\python26\lib\site-packages\selenium-2.12.1-py2.6.egg\selenium\webdriver\remote\webdriver.py", line 385, in ex ecute_script {'script': script, 'args':converted_args})['value'] File "c:\python26\lib\site-packages\selenium-2.12.1-py2.6.egg\selenium\webdriver\remote\webdriver.py", line 153, in ex ecute self.error_handler.check_response(response) File "c:\python26\lib\site-packages\selenium-2.12.1-py2.6.egg\selenium\webdriver\remote\errorhandler.py", line 110, in check_response if 'message' in value: TypeError: argument of type 'NoneType' is not iterable What am I not doing right?

• iPhone modalView unwanted offset

  - by Chonch

  Hey, I have a UITabBarController with three view controllers (from three different types). On one of the view controllers, I want to display a modalViewController. Once a UIButton on the screen is pressed, I perform this action: AboutViewController *modalViewController = [[AboutViewController alloc] initWithNibName:@"AboutScreen" bundle:nil]; [self presentModalViewController:modalViewController animated:YES]; like I always do in order to display a modal view... The problem is, that while the modal view is being displayed (while it is moving from the bottom of the screen), a 20 pixels grey strip is showing on the bottom of the screen (the same size as the status bar on the top). Once the modal view reaches its final location, the strip disappears. Needless to say this doesn't look good (to say the least). Does anybody know why this may happen? Thanks,

• How to map hash keys to methods for an encapsulated Ruby class (tableless model)?

  - by user502052

  I am using Ruby on Rails 3 and I am tryng to map a hash (key, value pairs) to an encapsulated Ruby class (tableless model) making the hash key as a class method that returns the value. In the model file I have class Users::Account #< ActiveRecord::Base def initialize(attributes = {}) @id = attributes[:id] @firstname = attributes[:firstname] @lastname = attributes[:lastname] end end def self.to_model(account) JSON.parse(account) end My hash is hash = {\"id\":2,\"firstname\":\"Name_test\",\"lastname\":\"Surname_test\"} I can make account = Users::Account.to_model(hash) that returns (debugging) --- id: 2 firstname: Name_test lastname: Surname_test That works, but if I do account.id I get this error NoMethodError in Users/accountsController#new undefined method `id' for #<Hash:0x00000104cda410> I think because <Hash:0x00000104cda410> is an hash (!) and not the class itself. Also I think that doing account = Users::Account.to_model(hash) is not the right approach. What is wrong? How can I "map" those hash keys to class methods?

• How to style content in jQuery Facebox

  - by musoNic80

  I'm using jQuery Facebox plugin to create some modal windows. One situation is to display errors that might occur. If JS is disabled, I do this by displaying any errors in a normal div that is styled by CSS using a class selector. If the user does have JS enabled however, that div is hidden and the info is displayed in a facebox. The problem I have is that all the CSS styling is lost when the data is displayed within a facebox window. I understand that you can attach extra classes if you're calling facebox from a rel attribute in an anchor tag, but I'm using it programatically. Is there a way I can bind something to the facebox method? Here's my js code (the HTML should be self-explanatory): $(document).ready(function() { $(".errors").hide(); // hides the non-js error div $.errors = $(".errors").html(); // get the html from the error div if($.errors!==''){ $.facebox($.errors); // if there are any errors, display them in facebox } });

• 'NSInvalidArgumentException' UIButton IBAction Error

  - by Graeme

  Hi, I have a button in a view which refuses to work. I've got in working in a blank, default view application from X-Code, but in none of my applications will it work, instead it gives me the following error. Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[UIViewController showVicInfo:]: unrecognized selector sent to instance 0x3c084f0' The debugger isn't any help either. I've made sure that I hook up the button to the file's owner (not the other way around) as well. Below is the code for the action. And I know it's not the alert view, because the breakpoint doesn't even reach there. about.h @interface about : UIViewController { } -(IBAction)showInfo:(id)sender; about.m -(IBAction)showVicInfo:(id)sender { UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"No Internet Connection" message:@"You require an internet connection via WiFi or cellular network for iFirelert to work." delegate:self cancelButtonTitle:@"OK, thanks" otherButtonTitles:nil]; [myAlert show]; [myAlert release]; }

• The accossoryView of a UITableViewCell disappears after the visible view is changed

  - by Luca

  Hi! I'm experiencing this strange situation. I have a UITableView where, when the user selects a cell, a long (network) process begins. So, I performed this in a background thread and I placed (in the didSelectRowAtIndexPath) a UIActivityIndicatorView as the accessory view. This is what I wrote: UITableViewCell* cell = [self.tableView cellForRowAtIndexPath:indexPath]; UIActivityIndicatorView* activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite]; cell.accessoryView = activityView; [activityView startAnimating]; [activityView release]; everything seems to work correctly, except that, if during a loading process (when the indicator is animated), I switch the view using a UITabBar, when I go back to the UITableView, the UIActivityIndicatorView that should still be there has disappeared. Any idea of what I did wrong? Thanks!

• PySide / PyQt QStyledItemDelegate list in table

  - by danodonovan

  Dear All, I'm trying to create a table of lists in Python with Qt (PySide/PyQt - matters not) and my lists are squashed into the table cells. Is there a way to get the list delegates to 'pop out' of their cells? I've attached a simple code snippet - replace 'PySide' with 'PyQt4' depending on your preference from PySide import QtCore, QtGui class ListDelegate(QtGui.QStyledItemDelegate): def createEditor(self, parent, option, index): editor = QtGui.QListWidget(parent) for i in range( 12 ): editor.addItem('list item %d' % i) return editor if __name__ == '__main__': import sys app = QtGui.QApplication(sys.argv) model = QtGui.QStandardItemModel(2, 2) tableView = QtGui.QTableView() delegate = ListDelegate() tableView.setItemDelegate(delegate) tableView.setModel(model) for row in range(2): for column in range(2): item = QtGui.QStandardItem( 'None' ) model.setItem(row, column, item) tableView.setWindowTitle('example') tableView.show() sys.exit(app.exec_()) If you hadn't guessed I'm pretty new to this Qt lark Thanks in advance, Dan

• iphone: view index

  - by Mike

  I have a view between other views, the order may vary. For example: viewA on top of viewB, on top of viewC, or in another order. Suppose I have viewA, viewB, viewC, viewD and viewE A is on the top and E on the bottom. I need to replace viewC with viewZ, but I need to insert viewZ in the same index of viewC. How do I know, before removing viewC, what index it has, so I can insert viewZ using [self.view insertSubview:viewZ atIndex:?????) and it will be at the same level? thanks for any help.

• Int or NSInteger as object for method argument. Objective-C

  - by sergiobuj

  Hi. I'm having some trouble passing a number as an argument for a method: -(void) meth2:(int)next_int; And to call that method i need this: int next_int = 1; [self performSelectorOnMainThread:@selector(meth2:) withObject:next_int waitUntilDone:NO]; //update next_int and call meth2 again at this point i get a "pointer from integer without a cast" error, and would happen the same with a NSInteger. A NSNumber is not useful because it's immutable and i need to change the value constantly. Any Idea how can i do this? Thanks.

• NavigationController pushViewController problems.

  - by Jacek

  Hello. I have created new a view controller in my project (ActivateController). I have added it to the interface of the parent view controller (PrefsViewController): #import <UIKit/UIKit.h> #import "ActivateController.h" @interface PrefsViewController : UIViewController <UITextFieldDelegate> { ActivateController *activateController; } -(IBAction)pressedActivate; @property(nonatomic,retain) IBOutlet ActivateController *activateController; @end I have also added it to parent's controller nib (and changed it type to ActivateController), and connected it to IBOutlet ActivateController. But still, when I perform (on pressedActivate): [self.navigationController pushViewController:activateController animated:YES]; Nothing happens. I have done it successfully many times before. What might be wrong? P.S. pressedActivate is executed for sure (I used NSLog to check).

• Anyone know how to use TValue.AsType<TNotifyEvent> properly?

  - by Mason Wheeler

  I'm trying to use RTTI to add an event handler to a control, that may already have an event handler set. The code looks something like this: var prop: TRttiProperty; val: TValue; begin prop := FContext.GetType(MyControl.ClassInfo).GetProperty('OnChange'); val := prop.GetValue(MyControl); FOldOnChange := val.AsType<TNotifyEvent>; prop.SetValue(MyControl, TValue.From<TNotifyEvent>(self.MyOnChange)); end; I want this so I can do this in MyOnChange: begin if assigned(FOldOnChange) then FOldOnChange(Sender); //additional code here end; Unfortunately, the compiler doesn't seem to like the line FOldOnChange := val.AsType<TNotifyEvent>;. It says E2010 Incompatible types: 'procedure, untyped pointer or untyped parameter' and 'TNotifyEvent' Anyone know why that is or how to fix it? It looks right to me...

• Microsoft Quotation

  - by Asad Jibran Ahmed

  I don't know if this is the right place to ask this question, but I honestly have exhausted my self searching for the last hour. I am looking for a quotation made about Microsofts software. It goes something along the lines of: "They may make 2nd grade crappy software, but by God they know how to design interfaces" It was by a somewhat popular open source personality about the lack of good interface design in open source software. Does any one know the exact quotation? It will be a great help if someone can point me in the right direction.

• Ruby on Rails protect_from_forgery best practice

  - by randombits

  I'm currently working on building a RESTful web api with ruby on rails. I haven't bothered putting a proper authentication scheme into the API yet as I'm ensuring that tests and the basic behavior of the API is working all locally first. Upon testing non-HTTP GET type requests such as HTTP POST/DELETE/PUT, stuff chokes because protect_from_forgery is on by default. How does this work when I'm working in practice since essentially the idea is in a RESTful API that there is no state. The client does not have a session or a cookie associated with the server. Each request is an atomic, self-executed request. The user will supply some credentials to ensure they are who they say they are, but other than that, does protect_from_forgery make sense at this point? Should it remain enabled?

• dismissModalViewControllerAnimated: crashes in Simulator but not on phone

  - by Jon

  I'm doing the following: [self.parentViewController dismissModalViewControllerAnimated:YES] This code fails using the Simulator but works with no issues on the phone itself. The Simulator's console shows no erros. I used NSLog statements to pinpoint this line of code as the culprit. When running on the phone, however, the console(windoworganizer) shows that the above code is executed and the application proceeds forward with no problem. When running the code in debugger, the following statement appears at the bottom of the Xcode debug window: GDB: Data Formatters temporarily unavailable, will re-try after a 'continue'. (Not safe to call dlopen at this time.) Then a window dispalys stating: Loading 43672 stack frames. (that sounds bad) In the debug window the following line appears numerous times: [UIView(Hierarchy) _makeSubtreePerformSelector:withObject:withObject:copySublayers:] Without getting too deep into my code, does anyone know about or have experience with this type of condition? Thanks

• Using sectioned tables from an sqlite file with an iPhone uitableview

  - by Chris

  I am currently trying to make a sectioned table like this: Section 1: Entry 1 Entry 2 Entry 3 Section 2: Entry 4 Entry 5 Entry 6 Section 3: Entry 7 Entry 8 ... However, using this code: Event *lists = (Event *)[eventList objectAtIndex:indexPath.row]; accessStatement = "select * from DatabaseName"; [self findEvents]; // Code that builds each object's strings from database cell.textLabel.text = lists.name; Section 1: Entry 1 Entry 2 Entry 3 Section 2: Entry 1 Entry 2 Entry 3 Section 3: Entry 1 Entry 2 ... It keeps on repeating itself. How do I make the index so that it continues in each section rather than restarts? Thanks in advance.

• How can I pre-authorize authopen?

  - by Georg

  I'm using authopen inside one of my programs to modify files owned by root. As can be seen in the screenshot below authopen asks for a admin password. What I'd like to achieve is that the dialog shows my app's name and then passes the authorization to authopen. Code Launching authopen which returns an authorized file descriptor. int pipe[2]; socketpair(AF_UNIX, SOCK_STREAM, 0, pipe); if (fork() == 0) { // child // close parent's pipe close(pipe[0]); dup2(pipe[1], STDOUT_FILENO); const char *authopenPath = "/usr/libexec/authopen"; execl(authopenPath, authopenPath, "-stdoutpipe", [self.device.devicePath fileSystemRepresentation], NULL); NSLog(@"Fatal error, quitting."); exit(-1); } // parent // close childs's pipe close(pipe[1]); // get file descriptor through sockets I'd really like not to use AuthorizationExecuteWithPrivileges because then I'd have to get more rights than I want to.

• Inherit a parent class docstring as __doc__ attribute

  - by Reinout van Rees

  There is a question about Inherit docstrings in Python class inheritance, but the answers there deal with method docstrings. My question is how to inherit a docstring of a parent class as the __doc__ attribute. The usecase is that Django rest framework generates nice documentation in the html version of your API based on your view classes' docstrings. But when inheriting a base class (with a docstring) in a class without a docstring, the API doesn't show the docstring. It might very well be that sphinx and other tools do the right thing and handle the docstring inheritance for me, but django rest framework looks at the (empty) .__doc__ attribute. class ParentWithDocstring(object): """Parent docstring""" pass class SubClassWithoutDoctring(ParentWithDocstring): pass parent = ParentWithDocstring() print parent.__doc__ # Prints "Parent docstring". subclass = SubClassWithoutDoctring() print subclass.__doc__ # Prints "None" I've tried something like super(SubClassWithoutDocstring, self).__doc__, but that also only got me a None.

• Is it possible to mask CALayer in iPhone?

  - by Eonil

  I'm trying to mask CALayer with a bitmap image. And I failed masking CALayer. My code is: // 'PreloadViewController layerWithImageNamed' create a layer and set it's contents as specified UIImage. CALayer* title = [PreloadViewController layerWithImageNamed:@"pinkhug_txt.png"]; [[[self view] layer] addSublayer:title]; CALayer* title_mask = [PreloadViewController layerWithImageNamed:@"hug_mask.png"]; [title setMask:title_mask]; The Apple reference says "CALayer in iPhone does not support mask property". But there is a postings about this on SO. Is it possible? Or what's wrong with my code?

• Can somebody explain this Objective C method declaration syntax

  - by Doug R

  I'm working through an iPhone development book* without really knowing Objective C. For the most part I'm able to follow what's going on, but there are a few method declarations like the one below that I'm having a bit of trouble parsing. For example: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger) section { return [self.controllers count]; //controllers is an instance variable of type NSArray in this class } It looks this is a method called numberOfRowsInSection, and it returns an NSInteger, and takes an NSInteger as a parameter which is locally called 'section'. But I don't understand all the references to tableView, or why this takes a parameter when it is not used within the method. Can somebody clarify this? Thanks. *p. 258, Beginning iPhone 3 Development, by Mark and LaMarche, published by Apress

• iPad UIViewController loads as portrait when device is in landscape

  - by jud

  I have an application with 3 view controllers. They are all have shouldAutoRotateToInterfaceOrientation returning YES. The first two, my main menu and my submenu both autorotate just fine. The third viewcontroller, which programatically loads a UIImageView from a jpg file in the program's bundle, will only display in portrait. In the viewcontroller containing the image, i have this: NSString *imageName = [NSString stringWithFormat:@"%@-00%d.jpg",setPrefix,imageNumber]; UIImageView *pictureView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:imageName]]; pictureView.frame = CGRectMake(0, 0, 1024, 768); [self.view addSubview:pictureView]; and again, I have shouldAutoRotateToInterfaceOrientation returning YES for all orientations. My image shows up, but is sideways, and the 0,0,1024,768 values I used to make my rectangle start from the top right corner going down, instead of starting at the top left and going across (holding in landscape). Am I missing a parameter I need to set in order to ensure the imageview shows up in landscape instead of portrait?

• Subview position issue after UIOrientation (rotation) change

  - by asadqamber

  I have a viewController and have added a subview in it programatically. secondView.autoresizingMask = UIViewAutoresizingFlexibleWidth; [self.view addSubview:secondView]; I guess when the device rotates, my mainViewController knows that orientation changed, but the subview (secondView) inside the mainViewController does not know this, so I change its frame to landscape size in willRotateToInterfaceOrientation. secondView.frame = CGRectMake(0, 0, 480 , 260); This does not set in the correct position, it's 11 px below the NavigationBar. Why does it start from 11 px below the navigation bar? The navigation bar shrinks when we move from portrait to landscape mode and its because of this that my subview is 11px below.
