  • Table view with custom cell (programmatically)

    - by gotye
    Hey guys, So far, I used to create custom nibs to make my cell as I wanted but this time, the height of a cell will change from one to another so that I can't create a fixed-size cell's nib. So I decided to create it programmatically ... Is the way below the good way to achieve it ? // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; UILabel *pseudoAndDate = [[UILabel alloc] initWithFrame:CGRectMake(0.0,0.0,320.0,20.0)]; [pseudoAndDate setTag:1]; [cell addSubview:pseudoAndDate]; [pseudoAndDate release]; } CommentRecord *thisRecord = [comments objectAtIndex:[indexPath row]]; UILabel *label = (UILabel *)[cell viewWithTag:1]; [label setText:[NSString stringWithFormat:@"%@ | %@",thisRecord.author,thisRecord.date]]; return cell; } or .. am i missing something here ? Cause so far it doesn't seem to work ;) Thanks, Gotye.

  • Testing if a UI element is hidden in an OCUnit test

    - by Logan Serman
    I have a button that is hidden under certain circumstances that I wish to test. The button is hidden with [theButton setHidden: YES] in the viewDidLoad method if it is appropriate. For simplicity, lets say that the button is hidden when the buttonIsHidden property is set to true in the view controller. Right now I am trying the following: self.viewController = [[ViewController alloc] init]; self.viewController.buttonIsHidden = YES; [self.viewController loadView]; UIButton *theButton = [...] // function I wrote to retrieve the button based on it's touch up inside action if (theButton) { NSLog(@"%c", theButton.hidden); return (theButton.hidden == true) } return NO; It looks like the hidden property is not what it should be, the NSLog lines from the above code are blank. But, if I output another property like the height, it outputs the correct value so I know it is getting the right button. How do I access the hidden property of the button in this case?

  • Rails: creating a custom data type, to use with generator classes and a bunch of questions related t

    - by Shyam
    Hi, After being productive with Rails for some weeks, I learned some tricks and got some experience with the framework. About 10 days ago, I figured out it is possible to build a custom data type for migrations by adding some code in the Table definition. Also, after learning a bit about floating points (and how evil they are) vs integers, the money gem and other possible solutions, I decided I didn't WANT to use the money gem, but instead try to learn more about programming and finding a solution myself. Some suggestions said that I should be using integers, one for the whole numbers and one for the cents. When playing in script/console, I discovered how easy it is to work with calculations and arrays. But, I am talking to much (and the reason I am, is to give some sufficient background). Right now, while playing with the scaffold generator (yes, I use it, because I like they way I can quickly set up a prototype while I am still researching my objectives), I like to use a DRY method. In my opinion, I should build a custom "object", that can hold two variables (Fixnum), one for the whole, one for the cents. In my big dream, I would be able to do the following: script/generate scaffold Cake name:string description:text cost:mycustom Where mycustom should create two integer columns (one for wholes, one for cents). Right now I could do this by doing: script/generate scaffold Cake name:string description:text cost_w:integer cost_c:integer I had also had an idea that would be creating a "cost model", which would hold two columns of integers and create a cost_id column to my scaffold. But wouldn't that be an extra table that would cause some kind of performance penalty? And wouldn't that be defy the purpose of the Cake model in the first place, because the costs are an attribute of individual Cake entries? The reason why I would want to have such a functionality because I am thinking of having multiple "costs" inside my rails application. Thank you for your feedback, comments and answers! I hope my message got through as understandable, my apologies for incorrect grammar or weird sentences as English is not my native language.

  • Android Animate Rotate

    - by oriharel
    I did some digging in Android code, and saw the use of in the indeterminate progress bar. after trying to create my own drawable with this tag: <animated-rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/spinner_pia" android:pivotX="50%" android:pivotY="50%" android:framesCount="12" android:frameDuration="100" /> I get an error: "No resource identifier found for attribute 'frameDuration' in package 'android'" - which means that frameDuration is a private attribute. Is there a way to use this "animate-rotate" feature? My task is to replace the system's default indeterminate progress bar. I'd like to do it with as little code as possible (just change few attributes if possible). Using the ProgressBar view, setting: android:indeterminateOnly="true" android:indeterminateBehavior="cycle" android:indeterminateDuration="3500" android:indeterminateDrawable="@drawable/pia_sivuvator" and point "@drawable/pia_sivuvator" to that object would've make my task as elegant as they come but I'm stuck on those private attributes. help?

  • Emacs, C++ code completion for vectors

    - by Caglar Toklu
    Hi, I am new to Emacs, and I have the following code as a sample. I have installed GNU Emacs 23.1.1 (i386-mingw-nt6.1.7600), installed cedet-1.0pre7.tar.gz. , installed ELPA, and company. You can find my simple Emacs configuration at the bottom. The problem is, when I type q[0] in main() and press . (dot), I see the 37 members of the vector, not Person although first_name and last_name are expected. The completion works as expected in the function greet() but it has nothing to do with vector. My question is, how can I accomplish code completion for vector elements too? #include <iostream> #include <vector> using namespace std; class Person { public: string first_name; string last_name; }; void greet(Person a_person) { // a_person.first_name is completed as expected! cout << a_person.first_name << "|"; cout << a_person.last_name << endl; }; int main() { vector<Person> q(2); Person guy1; guy1.first_name = "foo"; guy1.last_name = "bar"; Person guy2; guy2.first_name = "stack"; guy2.last_name = "overflow"; q[0] = guy1; q[1] = guy2; greet(guy1); greet(guy2); // cout q[0]. I want to see first_name or last_name here! } My Emacs configuration: ;;; This was installed by package-install.el. ;;; This provides support for the package system and ;;; interfacing with ELPA, the package archive. ;;; Move this code earlier if you want to reference ;;; packages in your .emacs. (when (load (expand-file-name "~/.emacs.d/elpa/package.el")) (package-initialize)) (load-file "~/.emacs.d/cedet/common/cedet.el") (semantic-load-enable-excessive-code-helpers) (require 'semantic-ia) (global-srecode-minor-mode 1) (semantic-add-system-include "/gcc/include/c++/4.4.2" 'c++-mode) (semantic-add-system-include "/gcc/i386-pc-mingw32/include" 'c++-mode) (semantic-add-system-include "/gcc/include" 'c++-mode) (defun my-semantic-hook () (imenu-add-to-menubar "TAGS")) (add-hook 'semantic-init-hooks 'my-semantic-hook)

I'm in the process of doing some UIs for a touch screen, but not sure how the template should look like. e.g. how big the buttons/text/labels should be. If anyone has experience in doing s similar stuff, pls share some references you have. thanks BB

  • Can I use foreign key restrictions to return meaningful UI errors with PHP

    - by Shane
    I want to start by saying that I am a big fan of using foreign keys and have a tendency to use them even on small projects to keep my database from being filled with orphaned data. On larger projects I end up with gobs of keys which end up covering upwards of 8 - 10 layers of data. I want to know if anyone could suggest a graceful way of handling 'expected errors' from the MySQL database in a way that I can construct meaningful messages for the end user. I will explain 'expected errors' with an example. Lets say I have a set of tables used for basic discussions: discussion questions responses users Hierarchically they would probably look something like this: -users --discussion ---questions ----responses When I attempt to delete a user the FKs will check discussions and if any discussion exist the deletion is restricted, deleting discussion checks questions, deleting questions checks responses. An 'expected error' in this case would be attempting to delete a user--unless they are newly created I can anticipate that one or more foreign keys will fail causing an error. What I WANT to do is to catch that error on deletion and be able to tell the end user something like 'We're sorry, but all discussions must be removed before you can delete this user...'. Now I know I can keep and maintain matching arrays in PHP and map specific errors to messages but that is messy and prone to becoming stagnant, or I could manually run a set of selects prior to attempting the deletion, but then I am doing just as much work as without using FKs. Any help here would be greatly appreciated, or if I am just looking at this completely wrong then please let me know. On a side note I generally use CodeIgniter for my application development, so if that would open up an avenue through that framework please consider that in your answers. Thanks in Advance

  • How can I revert a 'draggable' upon failed AJAX request?

    - by Frank
    I have a draggable div, that needs to be dropped on a droppable. If it is dropped correctly, the droppable calls an AJAX request. If the draggable does not have a valid id or the AJAX request fails, the draggable should be reverted to it's original position. Is that something that can be done with jQuery?! Any help is greatly appreciated!! $("div.draggable").livequery(function(){ $(this).draggable({ revert: 'invalid', distance: 20 }) }); $("#trash").droppable({ tolerance: 'touch', drop: function(event, ui) { var item = ui.draggable; var id = item.attr('id'); if (id) { $.ajax( { type: "POST", url: "delete.php", data: "id=" + id, success: function(html) { if (html) { item.remove(); } else { // FAILED AFTER AJAX // is it possible to revert the draggable from here?? } } }); } else { // FAILED BEFORE AJAX // is it possible to revert the draggable from here?? } } });

  • Manually Adjusting UI for Rotation

    - by Driss Zouak
    In my view I have some number-pad type buttons that I want to manually adjust their X and Y when the view is rotated. I'm having trouble figuring out how to support this. I have added in my ViewDidLoad NSNotificationCenter.DefaultCenter.AddObserver("UIDeviceOrientationDidChangeNotification", DeviceRotated ); And I defined my DeviceRotated but the breakpoint is never hit. I thought this might be because of the Autorotate, so I overrided the ShouldAutorotateToInterfaceOrientation and set that to false (true didn't work either). I figured there should be some WillRotate (but that's a void return type) or something that would allow me to indicate that I want the View to rotate, and whatever is set to auto adjust I'd like it to do that, but that I would like to be able to manually adjust any other items that I need. If I have to do everything myself, that's fine as well. Any advice would be appreciated, Driss.

  • Free/open source code editor UI control for .Net

    - by Daniel I-S
    I'm looking for a free, syntax-highlighting, possibly autocompleting 'code editor's textbox' style control for use in a Visual Studio winforms or wpf project. It should work with C# and self-defined languages. There are pay-for solutions available - something like http://www.syncfusion.com/products/user-interface-edition/windows-forms/Edit would work fine - but I am looking for something simpler, and don't need to pay for unnecessary functionality. Any ideas?

  • CQRS, Commands, Javascript

    - by Tolu
    I have an architecture where a task-based UI passes commands to a service layer. Now, my intention is to implement the UI in javascript, using KendoUI and the service layer, domain layer etc. in .NET. I'm also looking at future mobile implementations of the client that may use say Java rather than Javascript. If I define the commands in .NET, I'd like to know how to use them from my Javascript client so the client can communicate the commands appropriately to service layer. Do I have to use something like Apache Thrift for this i.e. to define the commands at both the client and service layer?

  • Why does jquery button take a second to refresh after updating a page using ajax

    - by oo
    when i refresh a part of a webpage that has a jquery ui button, it seems like I have to call: $(":button").button(); again or it shows up as a regular button. Thats fine but when i do this, it still shows up as a regular button for a split second before converting to the styling of the jquery theme. is there anyway to avoid this as it looks a bit messy. NOTE: i noticed that this is for anything that i am theming using jquery ui like autocomplete, button, etc. so its not button specific issue.

  • Sex appeal of computer graphics: movie like UI systems [closed]

    - by anon
    It's well know that 1) the way computers actually work 2) the way computers are protrayed in movies are not the same. In particular (2) looks much much cooler than (1). Where can I learn more about making flashy, superficially useful but deepdown useless fancy graphics UIs like that? It's almost in the realm of "hollywood special effects" -- like fire/smoke/fire, but I don't want natural phenomenon; I want user interfaces. Concrete question: where can I learn about creating flashy, cool looking (though not necessairly useful) user interfaces? [Perferably in OpenGL]

  • Document key usage in Dictionary

    How can I document the key usage in a Dictionary so that it shows in Visual studio when coding using that object? I'm looking for something like: /// <param name="SpecialName">That Special Name</param> public Dictionary<string,string> bar; So far the best attempt has been to write my own class: public class SpecialNameDictionary : IDictionary<string, string> { private Dictionary<string, string> data = new Dictionary<string, string>(); /// <param name="specialName">That Special Name</param> public string this[string specialName] { get { return data[specialName]; } } } But It adds a lot of code that doesn't do anything. Additionally I must retype every Dictionary method to make it compile. Is there a better way to achive the above?
