  • Zoom in on a point (using scale and translate)

    - by csiz
    I want to be able to zoom in on the point under the mouse in canvas with the mouse whell, like when zooming on maps.google. I'd like straight code as I've been working on this for 5h+ Something to start with: <canvas id="canvas" width="800" height="600"></canvas> <script type="text/javascript"> var canvas = document.getElementById("canvas"); var context = canvas.getContext("2d"); var scale = 1; var originx = 0; var originy = 0; function draw(){ context.fillStyle = "white"; context.fillRect(originx,originy,800/scale,600/scale); context.fillStyle = "black"; context.fillRect(50,50,100,100); } setInterval(draw,100); canvas.onmousewheel = function (event){ var mousex = event.clientX - canvas.offsetLeft; var mousey = event.clientY - canvas.offsetTop; var wheel = event.wheelDelta/120;//n or -n var zoom = 1 + wheel/2; scale *= zoom; originx += 0;//??? originy += 0;//??? context.scale(zoom,zoom); context.translate(0,0);//??? } </script>

  • Translate Java class with static attributes and Annotation to Scala equivalent

    - by ifischer
    I'm currently trying to "translate" the following Java class to an equivalent Scala class. It's part of a JavaEE6-application and i need it to use the JPA2 MetaModel. import javax.persistence.metamodel.SingularAttribute; import javax.persistence.metamodel.StaticMetamodel; @StaticMetamodel(Person.class) public class Person_ { public static volatile SingularAttribute<Person, String> name; } A dissassembling of the compiled class file reveals the following information for the compiled file: > javap Person_.class : public class model.Person_ extends java.lang.Object{ public static volatile javax.persistence.metamodel.SingularAttribute name; public model.Person_(); } So now i need an equivalent Scala file that has the same structure, as JPA depends on it, cause it resolves the attributes by reflection to make them accessible at runtime. So the main problem i think is that the attribute is static, but the Annotation has to be on an (Java)Object (i guess) My first naive attempt to create a Scala equivalent is the following: @StaticMetamodel(classOf[Person]) class Person_ object Person_ { @volatile var name:SingularAttribute[Person, String] = _; } But the resulting classfile is far away from the Java one, so it doesn't work. When trying to access the attributes at runtime, e.g. "Person_.firstname", it resolves to null, i think JPA can't do the right reflection magic on the compiled classfile (the Java variant resolves to an instance of org.hibernate.ejb.metamodel.SingularAttributeImpl at runtime). > javap Person_.class : public class model.Person_ extends java.lang.Object implements scala.ScalaObject{ public static final void name_$eq(javax.persistence.metamodel.SingularAttribute); public static final javax.persistence.metamodel.SingularAttribute name(); public model.Person_(); } > javap Person_$.class : public final class model.Person__$ extends java.lang.Object implements scala.ScalaObject public static final model.Person__$ MODULE$; public static {}; public javax.persistence.metamodel.SingularAttribute name(); public void name_$eq(javax.persistence.metamodel.SingularAttribute); } So now what i'd like to know is if it's possible at all to create a Scala equivalent of the Java class? It seems to me that it's absolutely not, but maybe there is a workaround or something (except just using Java, but i want my app to be in Scala where possible) Any ideas, anyone? Thanks in advance!

  • Translate RoR Code to Java

    - by mnml
    Hi, for some reasons I am trying to translate the following RoR view code to a Java Groovy view: <% modulo_artists = @artists.length % 3 base = @artists.length / 3 base = base.ceil case modulo_artists when 0 cols = [base, base, base] when 1 cols = [base, base + 1, base] when 2 cols = [base + 1, base, base + 1] end counter = 0 %> <% id_hash = {"0" => "url('/images/actorsbg.png');", "1" => "url('/images/musiciansbg.png');", "2" => "url('/images/artistsbg.png') no-repeat; color: #FFF;", "3" => "url('/images/fashionbg.png')"} %> <div id="artists_<%=params[:artist_cat]%>" style="background: <%= id_hash[params[:artist_cat]] %>;" > <table border="0" width="660" height="164" cellpadding="0" cellspacing="0"> <tr valign="middle"> <% 3.times do |i| %> <td width="220" align="center" style="padding-right: 15px;"> <% cols[i].times do %> <h1><a href="/artists/show/<%= @artists[counter].urlname %>" ><%= @artists[counter].name %></a></h1> <% counter = counter + 1 %> <% end %> </td> <% end %> </tr> </table> </div> This is what I got so far: #{extends 'main.html' /} %{ modulo_artists = artists.size() % 3 base = artists.size() / 3 base = Math.ceil(base) if(modulo_artists == 0) cols = [base, base, base] else if(modulo_artists == 1) cols = [base, base + 1, base] else if(modulo_artists == 2) cols = [base + 1, base, base + 1] endif counter = 0 }% <div id="artists_${artist_cat}" style="background:${id_hash};" > <table border="0" width="660" height="164" cellpadding="0" cellspacing="0"> <tr valign="middle"> #{list items:1..3, as:'i'} <td width="220" align="center" style="padding-right: 15px;"> #{list items:cols[i]} <h1><a href="@{Artists.show(artists.get(counter).name.replaceAll(" ", "-"))}" >${artists.get(counter).name}</a></h1> %{ counter = counter + 1 }% #{/list} </td> #{/list} </tr> </table> </div> The idea is to keep the items organised in 3 columns like 1|0|1 4|5|4 or 5|4|5 for example

  • Fetch pages translated by Google? (PHP)

    - by mathon12
    Hi, I have a bunch of big txt files (game walkthroughs) that I need translating from English to French. My first instinct was to host them on a server and use a PHP script to automate the translation process by doing a file_get_contents() and some URL manipulation to get the translated text. Something like: http://translate.google.com/translate?hl=fr&sl=en&u=http://mysite.com/faq.txt I found it poses two problems: 1) there are frames 2) the frame src values are relative (ie src="/translate_c?....") so nothing loads. Is there any way to fetch pages translated via Google in PHP (without using their AJAX API as it's really not suitable here)?

  • certain Smarty tags don't work in OpenX templates

    - by mikez302
    I am on a team that is developing an OpenX plugin, and I am responsible for the UI. I noticed that if I use certain Smarty tags in my template, the app doesn't work and I see an error message, similar to this: Plugin by name 'Html_select_date' was not found in the registry; used paths: default_views_helpers_: /openx/www/admin/plugins/myApp/application/modules/default/views/helpers/ OX_OXP_UI_View_Helper_: /openx/www/admin/plugins/myApp/application/../library/OX/OXP/UI/View/Helper/ OX_UI_View_Helper_: /openx/www/admin/plugins/myApp/application/../library/OX/UI/View/Helper/ Zend_View_Helper_: Zend/View/Helper/ (stack trace) The stack trace looks like this: #0 /openx/www/admin/plugins/myApp/library/Zend/View/Abstract.php(1117): Zend_Loader_PluginLoader-load('Html_select_dat...') #1 /openx/www/admin/plugins/myApp/library/Zend/View/Abstract.php(568): Zend_View_Abstract-_getPlugin('helper', 'html_select_dat...') #2 /openx/www/admin/plugins/myApp/library/OX/UI/Smarty/SmartyWithViewHelper.php(25): Zend_View_Abstract-getHelper('html_select_dat...') #3 /openx/var/templates_compiled/%2Fdefault%2Fviews%2Fscripts%2Findex%2Fview-reports.html^%%E8^E80^E80B56F2%%view-reports.html.php(38): OX_UI_Smarty_SmartyWithViewHelper-callViewHelper('html_select_dat...', Array) #4 /openx/lib/smarty/Smarty.class.php(1274): include('/openx...') #5 /openx/www/admin/plugins/myApp/library/OX/UI/View/SmartyView.php(103): Smarty-fetch('/openx...') #6 /openx/www/admin/plugins/myApp/library/Zend/View/Abstract.php(832): OX_UI_View_SmartyView-_run('/openx...') #7 /openx/www/admin/plugins/myApp/library/OX/UI/View/SmartyView.php(151): Zend_View_Abstract-render('index/view-repo...') #8 /openx/www/admin/plugins/myApp/library/OX/UI/View/Helper/WithViewScript.php(23): OX_UI_View_SmartyView-render('index/view-repo...') #9 /openx/www/admin/plugins/myApp/application/modules/default/views/helpers/ViewReports.php(5): OX_UI_View_Helper_WithViewScript::renderViewScript('index/view-repo...', Array) #10 /openx/www/admin/plugins/myApp/application/modules/default/controllers/IndexController.php(98): Default_Views_Helpers_ViewReports-renderPage() #11 /openx/www/admin/plugins/myApp/library/Zend/Controller/Action.php(512): IndexController-viewReportsAction() #12 /openx/www/admin/plugins/myApp/library/Zend/Controller/Dispatcher/Standard.php(288): Zend_Controller_Action-dispatch('viewReportsActi...') #13 /openx/www/admin/plugins/myApp/library/Zend/Controller/Front.php(945): Zend_Controller_Dispatcher_Standard-dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #14 /openx/www/admin/plugins/myApp/application/bootstrap.php(117): Zend_Controller_Front-dispatch() #15 /openx/www/admin/plugins/myApp/public/index.php(7): require('/openx...') #16 {main} This does not happen with all Smarty tags. For example, I can use {if}, {foreach}, or {assign} tags without any problems. But whenever I try to use {html_select_date}, {html_image}, or {html_table}, I get the errors. In case this matters, the programmer who is designing the plugin copied the openXWorkflow plugin and made some changes. I noticed that the openXWorkflow plugin has a file (openx/plugins_repo/openXWorkflow/www/admin/plugins/openXWorkflow/library/OX/UI/Smarty/SmartyCompilerWithViewHelper.php) with a class that overrides the default Smarty compiler, supposedly with the ability to compile shorthands for calling ZF view helpers. That file has a list of Smarty functions, but the list is incomplete. If I add the functions to the list, or simply delete the file, my template works fine, but I don't like to change library files. It may make the app hard to maintain, and I don't know if it will mess up something else. The file has the comment "There is no easy access to the list of Smarty's built-in functions so we need to list them here. HTML-specific functions are not included as we cover HTML generation separately.", so it seems like certain Smarty functions may be disabled on purpose for some reason. Will anything bad happen if I try to use them? If, for example, I want to use the {html_select_date} tag in my template, how would I go about doing that? Keep in mind that much of this stuff is new and unfamiliar to me. This is my first time ever using OpenX or Smarty, and I only have a little bit of experience with the Zend framework. Please let me know if we are using the wrong approach.

  • Translate ImageButton from C# to XAML

    - by Bill
    I worked out the C# code to create an ImageButton (below) that has three images (one base-image and two overlays) and three text boxes as the face of the button. I am inheriting from the Button class, which unfortunately includes several components that I didn't realize would surface until after coding and need to remove, namely the bright-blue surrounding border on IsMouseOver, and any visible borders between the buttons, as the buttons will end up in a wrapPanel and the borders need to be seamless. Now that the format has been worked out in C#, I expect that I need to translate to XAML so that I can create a ControlTemplate to get the functionality necessary, however I am not certain as to the process of translating from C# to XAML. Can anyone steer me in the right direction? public class ACover : Button { Image cAImage = null; Image jCImage = null; Image jCImageOverlay = null; TextBlock ATextBlock = null; TextBlock AbTextBlock = null; TextBlock ReleaseDateTextBlock = null; private string _TracksXML = ""; public ACover() { Grid cArtGrid = new Grid(); cArtGrid.Background = new SolidColorBrush(Color.FromRgb(38, 44, 64)); cArtGrid.Margin = new System.Windows.Thickness(5, 10, 5, 10); RowDefinition row1 = new RowDefinition(); row1.Height = new GridLength(225); RowDefinition row2 = new RowDefinition(); row2.Height = new GridLength(0, GridUnitType.Auto); RowDefinition row3 = new RowDefinition(); row3.Height = new GridLength(0, GridUnitType.Auto); RowDefinition row4 = new RowDefinition(); row4.Height = new GridLength(0, GridUnitType.Auto); cArtGrid.RowDefinitions.Add(row1); cArtGrid.RowDefinitions.Add(row2); cArtGrid.RowDefinitions.Add(row3); cArtGrid.RowDefinitions.Add(row4); ColumnDefinition col1 = new ColumnDefinition(); col1.Width = new GridLength(0, GridUnitType.Auto); cArtGrid.ColumnDefinitions.Add(col1); jCImage = new Image(); jCImage.Height = 240; jCImage.Width = 260; jCImage.VerticalAlignment = VerticalAlignment.Top; jCImage.Source = new BitmapImage(new Uri(Properties.Settings.Default.pathToGridImages + "jc.png", UriKind.Absolute)); cArtGrid.Children.Add(jCImage); cArtImage = new Image(); cArtImage.Height = 192; cArtImage.Width = 192; cArtImage.Margin = new System.Windows.Thickness(3, 7, 0, 0); cArtImage.VerticalAlignment = VerticalAlignment.Top; cArtGrid.Children.Add(cArtImage); jCImageOverlay = new Image(); jCImageOverlay.Height = 192; jCImageOverlay.Width = 192; jCImageOverlay.Margin = new System.Windows.Thickness(3, 7, 0, 0); jCImageOverlay.VerticalAlignment = VerticalAlignment.Top; jCImageOverlay.Source = new BitmapImage(new Uri( Properties.Settings.Default.pathToGridImages + "jc-overlay.png", UriKind.Absolute)); coverArtGrid.Children.Add(jCImageOverlay); ATextBlock = new TextBlock(); ATextBlock.Foreground = new SolidColorBrush(Color.FromRgb(173, 176, 198)); ATextBlock.Margin = new Thickness(10, -10, 0, 0); cArtGrid.Children.Add(ATextBlock); AlTextBlock = new TextBlock(); AlTextBlock.Margin = new Thickness(10, 0, 0, 0); AlTextBlock.Foreground = new SolidColorBrush(Color.FromRgb(173, 176, 198)); cArtGrid.Children.Add(AlTextBlock); RDTextBlock = new TextBlock(); RDTextBlock.Margin = new Thickness(10, 0, 0, 0); RDTextBlock.Foreground = new SolidColorBrush(Color.FromRgb(173, 176, 198)); cArtGrid.Children.Add(RDTextBlock); Grid.SetColumn(jCImage, 0); Grid.SetRow(jCImage, 0); Grid.SetColumn(jCImageOverlay, 0); Grid.SetRow(jCImageOverlay, 0); Grid.SetColumn(cArtImage, 0); Grid.SetRow(cArtImage, 0); Grid.SetColumn(ATextBlock, 0); Grid.SetRow(ATextBlock, 1); Grid.SetColumn(AlTextBlock, 0); Grid.SetRow(AlTextBlock, 2); Grid.SetColumn(RDTextBlock, 0); Grid.SetRow(RDTextBlock, 3); this.Content = cArtGrid; } public string A { get { if (ATextBlock != null) return ATextBlock.Text; else return String.Empty; } set { if (ATextBlock != null) ATextBlock.Text = value; } } public string Al { get { if (AlTextBlock != null) return AlTextBlock.Text; else return String.Empty; } set { if (AlTextBlock != null) AlTextBlock.Text = value; } } public string RD { get { if (RDTextBlock != null) return RDTextBlock.Text; else return String.Empty; } set { if (RDTextBlock != null) RDTextBlock.Text = value; } } public ImageSource Image { get { if (cArtImage != null) return cArtImage.Source; else return null; } set { if (cArtImage != null) cArtImage.Source = value; } } public string TracksXML { get { return _TracksXML; } set { _TracksXML = value; } } public double ImageWidth { get { if (cArtImage != null) return cArtImage.Width; else return double.NaN; } set { if (cArtImage != null) cArtImage.Width = value; } } public double ImageHeight { get { if (cArtImage != null) return cArtImage.Height; else return double.NaN; } set { if (cArtImage != null) cArtImage.Height = value; } } }

  • Zend Framework - tinyMCE - plugin folders are mistaken to be controllers? Help

    - by Ali
    Hi guys I'm trying to integrate the tinymce plugin however I'm running into problems such that almost every feature which requires a plugin to be rendered i.e the add url popup or add image pop up - it opens an empty pop up window. Even if I try to open it inline I get the same blank popup window.. I noticed that whenever I click on lets say url button in tinymCE it opens with reference to my localhost and because of that I'm assuming my application is mistaking the containing javascript folder to be some controller or action. How can I fix this please - I've set up mod rewrite to allow clean urls as well as ignore the javascript folder but this is a different issue altogether :( what should I be looking at here.. I can't notice any error sin firebug..

  • PHP / Zend Framework: Force prepend table name to column name in result array?

    - by Brian Lacy
    I am using Zend_Db_Select currently to retrieve hierarchical data from several joined tables. I need to be able to convert this easily into an array. Short of using a switch statement and listing out all the columns individually in order to sort the data, my thought was that if I could get the table names auto-prepended to the keys in the result array, that would solve my problem. So considering the following (assembled) SQL: SELECT user.*, contact.* FROM user INNER JOIN contact ON contact.user_id = user.user_id I would normally get a result array like this: [username] => 'bob', [contact_id] => 5, [user_id] => 2, [firstname] => 'bob', [lastname] => 'larsen' But instead I want this: [user.user_id] => 2, [user.username] => 'bob', [contact.contact_id] => 5, [contact.firstname] => 'bob', [contact.lastname] => 'larsen' Does anyone have an idea how to achieve this? Thanks!
