  • Optimal pixel format for drawing on iPhone?

    - by Felixyz
    Pretty simple question: when doing some pretty intense drawing with CoreGraphics on the iPhone, how can I specify the pixel format to get optimal performance? Is the format that I get from the context via UIGraphicsGetCurrentContext per definition the best one? I know that RGB565 is supposed to be the fastest to use in OpenGL. Does that go for CoreGraphics as well? General advice?

  • Proper way to resignFirstResponder when a UITableView is touched?

    - by Topher Fangio
    Hello all, I have a pretty simple UITableView who's cells contain UITextFields and I need to be able to call resignFirstResponder to hide the keyboard whenever a user touches the UITableView outside of one of the cells. I have read this question/answer but it seems like a very rudimentary way to achieve this. I have read about a way to do it by converting the UITableView to a UIControl so that you can connect the TouchDown event. Does anybody know the standard or preferred way to achieve this functionality?

  • UIImage resize and crop to fit

    - by Amit Hagin
    I read a lot, also here, but couldn't find a simple way to do it: In objective c - I have a big UIImage and a small UIImageView. I want to programmatically shrink the content of a UIImage just enough to fit the smaller dimension within the UIImageView. The larger dimension will be cropped, and the result will be the maximum I can get from an image without changing the proportion. can you please help me?

  • How can I parse a namespace using the SAX parser?

    - by Silvestri
    Hello, Using a twitter search URL ie. http://search.twitter.com/search.rss?q=android returns CSS that has an item that looks like: <item> <title>@UberTwiter still waiting for @ubertwitter android app!!!</title> <link>http://twitter.com/meals69/statuses/21158076391</link> <description>still waiting for an app!!!</description> <pubDate>Sat, 14 Aug 2010 15:33:44 +0000</pubDate> <guid>http://twitter.com/meals69/statuses/21158076391</guid> <author>Some Twitter User</author> <media:content type="image/jpg" height="48" width="48" url="http://a1.twimg.com/profile_images/756343289/me2_normal.jpg"/> <google:image_link>http://a1.twimg.com/profile_images/756343289/me2_normal.jpg</google:image_link> <twitter:metadata> <twitter:result_type>recent</twitter:result_type> </twitter:metadata> </item> Pretty simple. My code parses out everything (title, link, description, pubDate, etc.) without any problems. However, I'm getting null on: <google:image_link> I'm using Java to parse the RSS feed. Do I have to handle compound localnames differently than I would a more simple localname? This is the bit of code that parses out Link, Description, pubDate, etc: @Override public void endElement(String uri, String localName, String name) throws SAXException { super.endElement(uri, localName, name); if (this.currentMessage != null){ if (localName.equalsIgnoreCase(TITLE)){ currentMessage.setTitle(builder.toString()); } else if (localName.equalsIgnoreCase(LINK)){ currentMessage.setLink(builder.toString()); } else if (localName.equalsIgnoreCase(DESCRIPTION)){ currentMessage.setDescription(builder.toString()); } else if (localName.equalsIgnoreCase(PUB_DATE)){ currentMessage.setDate(builder.toString()); } else if (localName.equalsIgnoreCase(GUID)){ currentMessage.setGuid(builder.toString()); } else if (uri.equalsIgnoreCase(AVATAR)){ currentMessage.setAvatar(builder.toString()); } else if (localName.equalsIgnoreCase(ITEM)){ messages.add(currentMessage); } builder.setLength(0); } } startDocument looks like: @Override public void startDocument() throws SAXException { super.startDocument(); messages = new ArrayList<Message>(); builder = new StringBuilder(); } startElement looks like: @Override public void startElement(String uri, String localName, String name, Attributes attributes) throws SAXException { super.startElement(uri, localName, name, attributes); if (localName.equalsIgnoreCase(ITEM)){ this.currentMessage = new Message(); } } Tony

  • QTreeView memory consumption

    - by Eye of Hell
    Hello. I'm testing QTreeView functionality right now, and i was amazed by one thing. It seems that QTreeView memory consumption depends on items count O_O. This is highly unusual, since model-view containers of such type only keeps track for items being displayed, and rest of items are in the model. I have written a following code with a simple model that holds no data and just reports that it has 10 millions items. With MFC, Windows API or .NET tree / list with such model will take no memory, since it will display only 10-20 visible elements and will request model for more upon scrolling / expanding items. But with Qt, such simple model results in ~300Mb memory consumtion. Increasing number of items will increase memory consumption. Maybe anyone can hint me what i'm doing wrong? :) #include <QtGui/QApplication> #include <QTreeView> #include <QAbstractItemModel> class CModel : public QAbstractItemModel { public: QModelIndex index ( int i_nRow, int i_nCol, const QModelIndex& i_oParent = QModelIndex() ) const { return createIndex( i_nRow, i_nCol, 0 ); } public: QModelIndex parent ( const QModelIndex& i_oInex ) const { return QModelIndex(); } public: int rowCount ( const QModelIndex& i_oParent = QModelIndex() ) const { return i_oParent.isValid() ? 0 : 1000 * 1000 * 10; } public: int columnCount ( const QModelIndex& i_oParent = QModelIndex() ) const { return 1; } public: QVariant data ( const QModelIndex& i_oIndex, int i_nRole = Qt::DisplayRole ) const { return Qt::DisplayRole == i_nRole ? QVariant( "1" ) : QVariant(); } }; int main(int argc, char *argv[]) { QApplication a(argc, argv); QTreeView oWnd; CModel oModel; oWnd.setUniformRowHeights( true ); oWnd.setModel( & oModel ); oWnd.show(); return a.exec(); }

  • What's the difference between the ruby irb prompt modes?

    - by Steven
    I can change the irb prompt mode with irb --prompt prompt-mode I can see what null and simple does, but I can't tell the difference between null and xmp and the difference between default/classic/inf-ruby. Can someone explain to me what these other modes do? It seems pointless to have multiple modes doing the same thing.

  • How to determine if a .NET Type is a custom struct?

    - by SztupY
    Hi! How to write a simple method, that checks whether a concrete type is a custom struct (created with public struct { };) or not. Checking Type.IsValueType is not enough, because it is also true to int, long, etc, and adding a check to !IsPrimitiveType won't exclude decimal, DateTime and maybe some other value types. I know that most of the built in value types are actually "structs", but I only want to check for "custom structs" These questions are mostly the same but without the answer I need: #1 #2 #3

  • How can I pin a div in my sidebar column to the bottom?

    - by vg1890
    I have a simple two column layout with a footer at the bottom. When the content in the sidebar is taller than the content in the main column, everything looks great. But when the height of the main column is greater than the sidebar, I need the sidebar to grow to the same height as the main column and for the last <div> in the sidebar to be pinned to the very bottom. Here's my sample code: http://jsfiddle.net/mqnML/1/

  • using ruby-debug with jruby-1.5.0

    - by brad
    Release notes say that ruby-debug is installed by default. I'm using rvm. In my rails app I figured something as simple as script/server --debugger would suffice, but it complains that the ruby-debug gem isn't installed, suggests using gem install ruby-debug, which of course doesn't work (building native extensions) and is contrary to the docs anyway. Just wondering if anyone's had any luck using the built in ruby-debug in jruby 1.5 and what one needs to do in order run jruby in debug mode

  • Sending HTML email from PHP

    - by KevinM
    I am trying to send a simple HTML e-mail from PHP. The code below simply results in a blank e-mail in GMail. It also has an empty attachment called 'noname', which is not at all what I want; though that might just be a symptom of it not working. The code I am using is: <?php //define the receiver of the email $to = '[email protected]'; //define the subject of the email $subject = 'Test HTML email'; //create a boundary string. It must be unique //so we use the MD5 algorithm to generate a random hash $random_hash = md5(date('r', time())); //define the headers we want passed. Note that they are separated with \r\n $headers = "From: [email protected]\r\nReply-To: [email protected]"; //add boundary string and mime type specification $headers .= "\r\nContent-Type: multipart/alternative; boundary=\"PHP-alt-".$random_hash."\""; //define the body of the message. ob_start(); //Turn on output buffering ?> --PHP-alt-<?php echo $random_hash; ?> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Hello World!!! This is simple text email message. --PHP-alt-<?php echo $random_hash; ?> MIME-Version: 1.0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 7bit <h2>Hello World!</h2> <p>This is something with <b>HTML</b>formatting.</p> --PHP-alt-<?php echo $random_hash; ?>-- <? //copy current buffer contents into $message variable and delete current output buffer $message = ob_get_clean(); //send the email $mail_sent = @mail( $to, $subject, $message, $headers ); //if the message is sent successfully print "Mail sent". Otherwise print "Mail failed" echo $mail_sent ? "Mail sent" : "Mail failed";

  • Is it possible to implement Separated Interface in PHP?

    - by sunwukung
    I recently asked a question regarding the resolution of dependencies between Unit of Work and Data Mapper classes: http://stackoverflow.com/questions/3012657/dependency-injection-and-unit-of-work-pattern - (which was answered by Gabor de Mooij - thx) In PoEAA, Martin Fowler suggests using Separated Interface to manage these dependencies. My question is simple - is it actually possible to implement this pattern in PHP, or is it specific to Java interfaces? I've searched high and low and it's hard to find references to this pattern anywhere outside of PoEAA.

  • Rails: Easy way to add more than one flash[:notice] at a time.

    - by Josh Pinter
    I thought every time you do a flash[:notice]="Message" it would add it to the array which would then get displayed during the view but the following just keeps the last flash: flash[:notice] = "Message 1" flash[:notice] = "Message 2" Now I realize it's just a simple hash with a key (I think :)) but is there a better way to do multiple flashes than the following: flash[:notice] = "Message 1<br />" flash[:notice] = "Message 2" Thanks. Josh

  • Algorithm for bitwise fiddling

    - by EquinoX
    If I have a 32-bit binary number and I want to replace the lower 16-bit of the binary number with a 16-bit number that I have and keep the upper 16-bit of that number to produce a new binary number.. how can I do this using simple bitwise operator? For example the 32-bit binary number is: 1010 0000 1011 1111 0100 1000 1010 1001 and the lower 16-bit I have is: 0000 0000 0000 0001 so the result is: 1010 0000 1011 1111 0000 0000 0000 0001 how can I do this?
