  • Make accordeon/toggle menu using jquery or javascript

    - by Souza
    Found a solution: $('div.divname').not(':eq(0)').hide(); Check this page: http://www.iloja.pt/index.php?_a=viewDoc&docId=19 I would like to have ONLY the first text (faqtexto) open, and the one bellow, hidden on loading (by default) This is the HTML: <div class="agendarfaq"> <div class="topfaq"></div> <div class="faqtopics"><p class="textopics">Recolha e entrega, quanto tempo?</p></div> <div class="faqtexto"> Neque porro quisquam est, qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit, sed quia non numquam eius modi tempora incidunt ut labore et dolore magnam Quis autem vel eum iure reprehenderit qui in ea voluptate velit esse quam nihil molestiae consequatur, vel illum qui dolorem</div> <div class="faqtopics"><p class="textopics">Recolha e entrega, quanto tempo?</p></div> <div class="faqtexto"> Neque porro quisquam est, qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit, sed quia non numquam eius modi tempora incidunt ut labore et dolore magnam Quis autem vel eum iure reprehenderit qui in ea voluptate velit esse quam nihil molestiae consequatur, vel illum qui dolorem</div> </div> The jQuery I propose: $(".faqtopics").click(function(event) { $("div.faqtexto").slideUp(100); $(this).next("div.faqtexto").slideToggle(); }); Do you suggest any other cleaner jQuery code? Any help would be welcome! Thank you very much!

  • WPF ProgressBar - TargetParameterCountException

    - by Dr_Asik
    I am making my first WPF application, where I use the Youtube .NET API to upload a video to Youtube using the ResumableUploader. This ResumableUploader works asynchronously and provides an event AsyncOperationProgress to periodically report its progress percentage. I want a ProgressBar that will display this progress percentage. Here is some of the code I have for that: void BtnUpload_Click(object sender, RoutedEventArgs e) { // generate video uploader = new ResumableUploader(); uploader.AsyncOperationCompleted += OnDone; uploader.AsyncOperationProgress += OnProgress; uploader.InsertAsync(authenticator, newVideo.YouTubeEntry, new UserState()); } void OnProgress(object sender, AsyncOperationProgressEventArgs e) { Dispatcher.BeginInvoke((SendOrPostCallback)delegate { PgbUpload.Value = e.ProgressPercentage; }, DispatcherPriority.Background, null); } Where PgbUpload is my progress bar and the other identifiers are not important for the purpose of this question. When I run this, OnProgress will be hit a few times, and then I will get a TargetParameterCountException. I have tried several different syntax for invoking the method asynchronously, none of which worked. I am sure the problem is the delegate because if I comment it out, the code works fine (but the ProgressBar isn't updated of course). Thanks for any help.

  • NSTableView selection & highlights

    - by Christian
    I have a NSTableView as a very central part of my Application and want it to integrate more with the rest of it. It has only one column (it's a list) and I draw all Cells (normal NSTextFieldCells) myself. The first problem is the highlighting. I draw the highlight myself and want to get rid of the blue background. I now fill the whole cell with the original background color to hide the blue background, but this looks bad when dragging the cell around. I tried overriding highlight:withFrame:inView: and highlightColorWithFrame:inView: of NSCell but nothing happened. How can I disable automatic highlighting? I also want all rows/cells to be deselected when I click somewhere outside my NSTableView. Since the background / highlight of the selected cell turns gray there must be an event for this, but I can't find it. I let my cells expand on a double click and may need to undo this. So getting rid of the gray highlight is not enough. EDIT: I add a subview to the NSTableView when a cell gets double clicked and then resignFirstResponder of the NSTableView gets called. I tried this: - (BOOL)resignFirstResponder { if (![[self subviews] containsObject:[[self window] firstResponder]]) { [self deselectAll:self]; ... } return YES; } Besides that it's not working I would need to implement this method for all objects in the view hierarchy. Is there an other solution to find out when the first responder leaves a certain view hierarchy?

  • How do I know which Object I clicked?

    - by Nick
    Here's the deal: I'm working on a personal portfolio in AS3 and I've run into a problem which I can't seem to find a logical answer to. I want everything (well, most of it) to be editable with an XML file, including my menu. My menu is just a Sprite with some text on it and a Tweener-tween, no big deal. But, I forgot to think of a way how I can determine which menu-item I have clicked. This is in my Main.as private function xmlLoaded(e:Event):void { xml = e.target.xml; menu = new Menu(xml); menu.x = 0; menu.y = stage.stageHeight / 2 - menu.height / 2; addChild(menu); } In Menu.as public function Menu(xml:XML) { for each (var eachMenuItem:XML in xml.menu.item) { menuItem = new MenuItem(eachMenuItem); menuItem.y += yPos; addChild(menuItem); yPos += menuItem.height + 3; } } and in my MenuItem.as, everything works - I have a fancy tween when I hover over it, but when I click a menu-item, I want something to appear ofcourse. How do I know which one I clicked? I've tried with pushing everything in an array, but that didn't work out well (or maybe I'm doing it wrong). Also tried a global counter, but that's not working either because the value will always be amount of items in my XML file. Also tried e.currentTarget in my click-function, but when I trace that, all of them are "Object Sprite".. I need something so I can give each a unique "name"? Thanks in advance!

  • Get controls ClientID/UniqueID between DetailsView and UpdatePanel

    - by robertpnl
    Hi guys, I like to know how to get the ClientID/UniqueID of a control inside a Detailsview controls EditItemTemplate element and when DetailsViews changing to Edit mode and DetailsView is inside a AJAX UpdatePanel. Without UpdatePanel, during PostBack I can get the ClientID's control, but now with an UpdatePanel. <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:DetailsView ID="DetailsView1" runat="server" DataSourceID="SqlDataSource1" AllowPaging="true" AutoGenerateEditButton="true"> <Fields> <asp:TemplateField> <EditItemTemplate> <asp:CheckBox runat="server" ID="chkboxTest" Text="CHECKBOX" /> </EditItemTemplate> </asp:TemplateField> </Fields> </asp:DetailsView> </ContentTemplate> </asp:UpdatePanel> As you see, the EditItemTemplate contains a Checkbox control. So i'm trying to get the ClientID of this checkbox when Detailsview is changing to the Edit mode. I need this value for handling Javascript. Catching the events ChangingMode/ChangedMode doesn't work; chkbox is null: void DetailsView1_ModeChanged(object sender, EventArgs e) { if (DetailsView1.CurrentMode == DetailsViewMode.Edit) var chkbox = DetailsView1.Rows[0].FindControl("chkxboxTest"); // <== is null } Maybe i'm using the wrong event? Someone can give me a tip about this? Thanks.

  • Changing html content of a div before and after ajax request

    - by R27
    I am trying to change the button "ADD" (in a div) to some text/img as soon as it is clicked. And after the ajax request is processed, in the success block , I want the div to get the button back. I see the ajax request is itself not getting processed. Can someone explain whats my mistake. I just removed the jsfiddle link and pasting the script here to avoid confusion about the dependencies. JS script var ajax_load = "Please wait..."; jQuery(document).ready(function($) { $("#add_button").click(function(event){ var st = $("#add_div").html(); $("#add_div").html(ajax_load); $("#sform").validate({ errorClass: "error", submitHandler: function (form) { alert('inside submit'); $.ajax({ type: "GET", url: 'form.cgi', data: $("#sform").serialize(), success: function (msg) { alert('msg'); $("#add_div").html(st); $("#sform")[0].reset(); } }); } }); }); }); And the html piece is <form id=sform>LABEL <input id=field1 type=text> <div id="add_div"> <input type="button" value="ADD" id="add_button"> </div> </form> I have jquery.validate.min.js script included.

  • Removing HttpModule for specific path in ASP.NET / IIS 7 application?

    - by soccerdad
    Most succinctly, my question is whether an ASP.NET 4.0 app running under IIS 7 integrated mode should be able to honor this portion of my Web.config file: <location path="auth/windows"> <system.webServer> <modules> <remove name="FormsAuthentication"/> </modules> </system.webServer> </location> I'm experimenting with mixed mode authentication (Windows and Forms - I know there are other questions on S.O. about the topic). Using IIS Manager, I've disabled Anonymous authentication to auth/windows/winauth.aspx, which is within the location path above. I have Failed Request Tracing set up to trace various HTTP status codes, including 302s. When I request the winauth.aspx page, a 302 HTTP status code is returned. If I look at the request trace, I can see that a 401 (unauthorized) was originally generated by the AnonymousAuthenticationModule. However, the FormsAuthenticationModule converts that to a 302, which is what the browser sees. So it seems as though my attempt to remove that module from the pipeline for pages in that path isn't working. But I'm not seeing any complaints anywhere (event viewer, yellow pages of death, etc.) that would indicate it's an invalid configuration. I want the 401 returned to the browser, which presumably would include an appropriate WWW-Authenticate header. A couple of other points: a) I do have <authentication mode="Forms"> in my Web.config, and that is what the 302 redirects to; b) I got the "name" of the module I'm trying to remove from the inetserv\config\applicationHost.config file. Anyone had any luck removing modules in this fashion? Thanks much, Donnie

  • How to cope with null results in SQL Tasks that return single rows in SSIS 2005?

    - by JSacksteder
    In a dataflow task, I can slip a rowcount into the processing flow and place the count into a variable. I can later use that variable to conditionally perform some other work if the rowcount was 0. This works well for me, but I have no corresponding strategy for sql tasks expected to return a single row. In that event, I'm returning those values into variables. If the lookup produces no rows, the sql task fails when assigning values into those variables. I can branch on that component failing, but there's a side effect of that - if I'm running the job as a SQL server agent job step, the step returns DTSER_FAILURE, causing the step to fail. I can tell the sql agent to disregard the step failure, but then I won't know if I have a legitimate error in that step. This seems harder than it should be. The only strategy I can think of is to run the same query with a count(*) aggregate and test if that returns a number 0 and if so running the query again without the count. That's ugly because I have the same query in two places that I need to keep in sync. Is there a better way?

  • Including partial views when applying the Mode-View-ViewModel design pattern

    - by Filip Ekberg
    Consider that I have an application that just handles Messages and Users I want my Window to have a common Menu and an area where the current View is displayed. I can only work with either Messages or Users so I cannot work simultaniously with both Views. Therefore I have the following Controls MessageView.xaml UserView.xaml Just to make it a bit easier, both the Message Model and the User Model looks like this: Name Description Now, I have the following three ViewModels: MainWindowViewModel UsersViewModel MessagesViewModel The UsersViewModel and the MessagesViewModel both just fetch an ObserverableCollection<T> of its regarding Model which is bound in the corresponding View like this: <DataGrid ItemSource="{Binding ModelCollection}" /> The MainWindowViewModel hooks up two different Commands that have implemented ICommand that looks something like the following: public class ShowMessagesCommand : ICommand { private ViewModelBase ViewModel { get; set; } public ShowMessagesCommand (ViewModelBase viewModel) { ViewModel = viewModel; } public void Execute(object parameter) { var viewModel = new ProductsViewModel(); ViewModel.PartialViewModel = new MessageView { DataContext = viewModel }; } public bool CanExecute(object parameter) { return true; } public event EventHandler CanExecuteChanged; } And there is another one a like it that will show Users. Now this introduced ViewModelBase which only holds the following: public UIElement PartialViewModel { get { return (UIElement)GetValue(PartialViewModelProperty); } set { SetValue(PartialViewModelProperty, value); } } public static readonly DependencyProperty PartialViewModelProperty = DependencyProperty.Register("PartialViewModel", typeof(UIElement), typeof(ViewModelBase), new UIPropertyMetadata(null)); This dependency property is used in the MainWindow.xaml to display the User Control dynamicly like this: <UserControl Content="{Binding PartialViewModel}" /> There are also two buttons on this Window that fires the Commands: ShowMessagesCommand ShowUsersCommand And when these are fired, the UserControl changes because PartialViewModel is a dependency property. I want to know if this is bad practice? Should I not inject the User Control like this? Is there another "better" alternative that corresponds better with the design pattern? Or is this a nice way of including partial views?

  • There was no endpoint listening at net.pipe://localhost/...

    - by virsum
    I have two WCF services hosted in a single Windows Service on a Windows Server 2003 machine. If the Windows service needs to access either of the WCF services (like when a timed event occurs), it uses one of the five named pipe endpoints exposed (different service contracts). The service also exposes HTTP MetadataExchange endpoints for each of the two services, and net.tcp endpoints for consumers external to the server. Usually things work great, but every once in a while I get an error message that looks something like this: System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at net.pipe://localhost/IPDailyProcessing that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. --- System.IO.PipeException: The pipe endpoint 'net.pipe://localhost/IPDailyProcessing' could not be found on your local machine. --- End of inner exception stack trace --- Server stack trace: at System.ServiceModel.Channels.PipeConnectionInitiator.GetPipeName(Uri uri) at System.ServiceModel.Channels.NamedPipeConnectionPoolRegistry.NamedPipeConnectionPool.GetPoolKey(EndpointAddress address, Uri via) at System.ServiceModel.Channels.ConnectionPoolHelper.EstablishConnection(TimeSpan timeout) at System.ServiceModel.Channels.ClientFramingDuplexSessionChannel.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.CallOpenOnce.System.ServiceModel.Channels.ServiceChannel.ICallOnce.Call(ServiceChannel channel, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.CallOnceManager.CallOnce(TimeSpan timeout, CallOnceManager cascade) at System.ServiceModel.Channels.ServiceChannel.EnsureOpened(TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs) at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation) at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message) It doesn't happen reliably, which is maddening because I can't repeat it when I want to. In my windows service I also have some timed events and some file listeners, but these are fairly infrequent events. Does anyone have any ideas why I might be encountering an issue? Any help would be greatly appreciated.

  • How to allow click-through and a cursor in a background app while not taking the active appearance a

    - by Peter Hosey
    Here are my goals: My application displays an overlay window above all applications' window. The user can draw in the overlay window. The mouse cursor changes to a specific cursor while in the overlay window. The application that has the active appearance before summoning the overlay window still has it while the overlay window is up and usable. The user does not need to click on the overlay window to activate it before they can draw. Drawing in the window does not steal the active appearance away from the application that has it. With LSUIElement, I get #1, #2, #3, and #5. With LSBackgroundOnly, I get #1, #2, #4, and #6. How can I satisify all of these goals without installing an event tap and processing the mouse events myself? Things I've tried: [NSApp preventWindowOrdering] in mouseDown: [NSApp activateIgnoringOtherApps:YES] in applicationWillFinishLaunching: [myWindow orderFront:nil] in applicationWillFinishLaunching: [myWindow makeKeyAndOrderFront:nil] in applicationWillFinishLaunching: [myWindow orderFrontRegardless] in applicationWillFinishLaunching: [myWindow makeMainWindow] in applicationWillFinishLaunching: (this caused failure of point 4 even with LSBackgroundOnly) SetThemeCursor in applicationWillFinishLaunching: (With LSUIElement) Implementing canBecomeMainWindow in my NSPanel subclass to return NO Except where otherwise noted, none of these made any difference. So, with LSUIElement, goals #4 and #6 remain; with LSBackgroundOnly, goals #3 and #5 remain. Any suggestions?

  • Validating Time & Date To Be At Least A Certain Amount Of Time In The Future

    - by MJH
    I've built a reservation form for a taxi company which works fine, but I'm having an issue with users making reservations that are due too soon in the future. Since the entire form is kind of long, I first want to make sure the user is not trying to make a reservation for less than an hour ahead of time, without them having to fill out the whole form. This is what I have come up with so far, but it's just not working: <?php //Set local time zone. date_default_timezone_set('America/New_York'); //Get current date and time. $current_time = date('Y-m-d H:i:s'); //Set reservation time variable $res_datetime = $_POST['res_datetime']; //Set event time. $event_time = strtotime($res_datetime); ?> <!doctype html> <html> <head> <meta charset="utf-8"> <title>Check Date and Time</title> </head> <?php //Check to be sure reservation time is at least one hour in the future. if (($current_time - $event_time) <= (3600)) { echo "You must make a reservation at least one hour ahead of time."; } ?> <form name="datetime" action="" method="post"> <input name="res_datetime" type="datetime-local" id="res_datetime"> <input type="submit"> </form> <body> </body> </html> How can I create a validation check to make sure the date and time of the reservation is at least one hour ahead of time?

  • Spring Integration 1.0 RC2: Streaming file content?

    - by gdm
    I've been trying to find information on this, but due to the immaturity of the Spring Integration framework I haven't had much luck. Here is my desired work flow: New files are placed in an 'Incoming' directory Files are picked up using a file:inbound-channel-adapter The file content is streamed, N lines at a time, to a 'Stage 1' channel, which parses the line into an intermediary (shared) representation. This parsed line is routed to multiple 'Stage 2' channels. Each 'Stage 2' channel does its own processing on the N available lines to convert them to a final representation. This channel must have a queue which ensures no Stage 2 channel is overwhelmed in the event that one channel processes significantly slower than the others. The final representation of the N lines is written to a file. There will be as many output files as there were routing destinations in step 4. *'N' above stands for any reasonable number of lines to read at a time, from [1, whatever I can fit into memory reasonably], but is guaranteed to always be less than the number of lines in the full file. How can I accomplish streaming (steps 3, 4, 5) in Spring Integration? It's fairly easy to do without streaming the files, but my files are large enough that I cannot read the entire file into memory. As a side note, I have a working implementation of this work flow without Spring Integration, but since we're using Spring Integration in other places in our project, I'd like to try it here to see how it performs and how the resulting code compares for length and clarity.

  • Which languages support class replacement?

    - by Alix
    Hi, I'm writing my master thesis, which deals with AOP in .NET, among other things, and I mention the lack of support for replacing classes at load time as an important factor in the fact that there are currently no .NET AOP frameworks that perform true dynamic weaving -- not without imposing the requirement that woven classes must extend ContextBoundObject or MarshalByRefObject or expose all their semantics on an interface. You can however do this in Java thanks to ClassFileTransformer: You extend ClassFileTransformer. You subscribe to the class load event. On class load, you rewrite the class and replace it. All this is very well, but my project director has asked me, quite in the last minute, to give him a list of languages that do / do not support class replacement. I really have no time to look for this now: I wouldn't feel comfortable just doing a superficial research and potentially putting erroneous information in my thesis. So I ask you, oh almighty programming community, can you help out? Of course, I'm not asking you to research this yourselves. Simply, if you know for sure that a particular language supports / doesn't support this, leave it as an answer. If you're not sure please don't forget to point it out. Thanks so much!

  • Using jQuery with Windows 8 Metro JavaScript App causes security error

    - by patridge
    Since it sounded like jQuery was an option for Metro JavaScript apps, I was starting to look forward to Windows 8 dev. I installed Visual Studio 2012 Express RC and started a new project (both empty and grid templates have the same problem). I made a local copy of jQuery 1.7.2 and added it as a script reference. <!-- SomeTestApp references --> <link href="/css/default.css" rel="stylesheet" /> <script src="/js/jquery-1.7.2.js"></script> <script src="/js/default.js"></script> Unfortunately, as soon as I ran the resulting app it tosses out a console error: HTML1701: Unable to add dynamic content ' a' A script attempted to inject dynamic content, or elements previously modified dynamically, that might be unsafe. For example, using the innerHTML property to add script or malformed HTML will generate this exception. Use the toStaticHTML method to filter dynamic content, or explicitly create elements and attributes with a method such as createElement. For more information, see http://go.microsoft.com/fwlink/?LinkID=247104. I slapped a breakpoint in a non-minified version of jQuery and found the offending line: div.innerHTML = " <link/><table></table><a href='/a' style='top:1px;float:left;opacity:.55;'>a</a><input type='checkbox'/>"; Apparently, the security model for Metro apps forbids creating elements this way. This error doesn't cause any immediate issues for the user, but given its location, I am worried it will cause capability-discovery tests in jQuery to fail that shouldn't. I definitely want jQuery $.Deferred for making just about everything easier. I would prefer to be able to use the selector engine and event handling systems, but I would live without them if I had to. How does one get the latest jQuery to play nicely with Metro development?

  • How can I differentiate a manual scroll (via mousewheel/scrollbar) from a Javascript/jQuery scroll?

    - by David Murdoch
    UPDATE: Here is a jsbin example demonstrating the problem. Basically, I have the following javascript which scrolls the window to an anchor on the page: // get anchors with href's that start with "#" $("a[href^=#]").live("click", function(){ var target = $($(this).attr("href")); // if the target exists: scroll to it... if(target[0]){ // If the page isn't long enough to scroll to the target's position // we want to scroll as much as we can. This part prevents a sudden // stop when window.scrollTop reaches its maximum. var y = Math.min(target.offset().top, $(document).height() - $(window).height()); // also, don't try to scroll to a negative value... y=Math.max(y,0); // OK, you can scroll now... $("html,body").stop().animate({ "scrollTop": y }, 1000); } return false; }); It works perfectly......until I manually try to scroll the window. When the scrollbar or mousewheel is scrolled I need to stop the current scroll animation...but I'm not sure how to do this. This is probably my starting point... $(window).scroll(e){ if(IsManuallyScrolled(e)){ $("html,body").stop(); } } ...but I'm not sure how to code the IsManuallyScrolled function. I've checked out e (the event object) in Google Chrome's console and AFAIK there is not way to differentiate between a manual scroll and jQuery's animate() scroll. How can I differentiate between a manual scroll and one called via jQuery's $.fn.animate function?

  • Which text margin does SWT Table use when drawing text?

    - by Zordid
    I got a relatively easy question - but I cannot find anything anywhere to answer it. I use a simple SWT table widget in my application that displays only text in the cells. I got an incremental search feature and want to highlight text snippets in all cells if they match. So when typing "a", all "a"s should be highlighted. To get this, I add an SWT.EraseItem listener to interfere with the background drawing. If the current cell's text contains the search string, I find the positions and calculate relative x-coordinates within the text using event.gc.stringExtent - easy. With that I just draw rectangles "behind" the occurrences. Now, there's a flaw in this. The table does not draw the text without a margin, so my x coordinate does not really match - it is slightly off by a few pixels! But how many?? Where do I retrieve the cell's text margins that table's own drawing will use? No clue. Cannot find anything. :-( Bonus question: the table's draw method also shortens text and adds "..." if it does not fit into the cell. Hmm. My occurrence finder takes the TableItem's text and thus also tries to mark occurrences that are actually not visible because they are consumed by the "...". How do I get the shortened text and not the "real" text within the EraseItem draw handler? Thanks!

  • Timer takes 10 ms more then interval

    Hi All, I am using a timer with interval 50 miliseconds. But in the timer's tick event when I print the time it's always 62 or 65 ms. I don't understand why it's taking 10 ms more.

  • How to print a page when a JButton is pressed in java swing using PrinterJob?

    - by Prayag Upd
    I tried the following code AWT but at runtime shows multiple print dialogs repeatedly.... package printerjob; import java.awt.BasicStroke; import java.awt.Frame; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.event.WindowAdapter; import java.awt.print.PageFormat; import java.awt.print.Printable; import java.awt.print.PrinterException; import java.awt.print.PrinterJob; /** * * @author pragX */ public class FramePrinterJob extends Frame implements Printable{ public void start(){ add(button); } @Override public void paint(Graphics graphics){ PrinterJob printerJob=PrinterJob.getPrinterJob(); printerJob.setPrintable(this); if(printerJob.printDialog()){ try{ printerJob.print(); }catch(PrinterException printerException){ //printerException.printStackTrace(); System.out.println("Error Printing." + printerException); } } } public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException { //throw new UnsupportedOperationException("Not supported yet."); if(pageIndex>=1){ return Printable.NO_SUCH_PAGE; } graphics.translate((int) pageFormat.getImageableX(), (int)pageFormat.getImageableY()); Graphics2D graphics2D=(Graphics2D)graphics; graphics2D.setStroke(new BasicStroke(4f)); graphics2D.drawLine(20, 20, 20, 120); graphics2D.drawLine(40, 20, 40, 120); graphics2D.drawLine(20, 70, 40, 70); graphics2D.drawLine(60, 70, 60, 120); graphics2D.drawLine(60, 40, 60, 45); return Printable.PAGE_EXISTS; } public static void main(String args[]){ Frame frame=new FramePrinterJob(); frame.addWindowListener(new WindowAdapter() { public void windowClosing(){System.exit(0);}}); frame.setSize(300,400); frame.setVisible(true); } }

  • [iText] Inserting Image onCloseDocument

    - by David
    I'm trying to insert an image in the footer of my document using iText's onCloseDocument event. I have the following code: public void onCloseDocument(PdfWriter writer, Document document) { PdfContentByte pdfByte = writer.getDirectContent(); try { // logo is a non-null global variable Image theImage = new Jpeg(logo); pdfByte.addImage(theImage, 400.0f, 0.0f, 0.0f, 400.0f, 0.0f, 0.0f); } catch (Exception e) { e.printStackTrace(); } } The code throws no exceptions, but it also fails to insert the image. This identical code is used onOpenDocument to insert the same logo. The only difference between the two methods are the coordinates in pdfByte.addImage. However, I've tried quite a few different coordinations in onCloseDocument and none of them appear anywhere in my document. Is there any troubleshooting technique for detecting content which is displayed off-page in a PDF? If not, can anyone see the problem with my onCloseDocument method? Edit: As a followup, it seems that onDocumentClose puts its content on page document.length() + 1 (according to its API). However, I don't know how to change the page number back to document.length() and place my logo on the last page.

  • How to force positioned elements to stay withing viewable browser area?

    - by jessegavin
    I have a script which inserts "popup" elements into the DOM. It sets their top and left css properties relative to mouse coordinates on a click event. It works great except that the height of these "popup" elements are variable and some of them extend beyond the viewable area of the browser window. I would like to avoid this. Here's what I have so far <script type="text/javascript"> $(function () { $("area").click(function (e) { e.preventDefault(); var offset = $(this).offset(); var relativeX = e.pageX - offset.left; var relativeY = e.pageY - offset.top; // 'responseText' is the "popup" HTML fragment $.get($(this).attr("href"), function (responseText) { $(responseText).css({ top: relativeY, left: relativeX }).appendTo("#territories"); // Need to be able to determine // viewable area width and height // so that I can check if the "popup" // extends beyond. $(".popup .close").click(function () { $(this).closest(".popup").remove(); }); }); }); }); </script>

  • Why is my simple python gtk+cairo program running so slowly/stutteringly?

    - by synapz
    My program draws circles moving on the window. I think I must be missing some basic gtk/cairo concept because it seems to be running too slowly/stutteringly for what I am doing. Any ideas? Thanks for any help! #!/usr/bin/python import gtk import gtk.gdk as gdk import math import random import gobject # The number of circles and the window size. num = 128 size = 512 # Initialize circle coordinates and velocities. x = [] y = [] xv = [] yv = [] for i in range(num): x.append(random.randint(0, size)) y.append(random.randint(0, size)) xv.append(random.randint(-4, 4)) yv.append(random.randint(-4, 4)) # Draw the circles and update their positions. def expose(*args): cr = darea.window.cairo_create() cr.set_line_width(4) for i in range(num): cr.set_source_rgb(1, 0, 0) cr.arc(x[i], y[i], 8, 0, 2 * math.pi) cr.stroke_preserve() cr.set_source_rgb(1, 1, 1) cr.fill() x[i] += xv[i] y[i] += yv[i] if x[i] > size or x[i] < 0: xv[i] = -xv[i] if y[i] > size or y[i] < 0: yv[i] = -yv[i] # Self-evident? def timeout(): darea.queue_draw() return True # Initialize the window. window = gtk.Window() window.resize(size, size) window.connect("destroy", gtk.main_quit) darea = gtk.DrawingArea() darea.connect("expose-event", expose) window.add(darea) window.show_all() # Self-evident? gobject.idle_add(timeout) gtk.main()

  • How do I initialize the controls in an InsertItemTemplate?

    - by Slauma
    I have - for instance - an asp:FormView which supports Read, Insert, Update, Delete and is bound to a DataSource: <asp:FormView ID="FormView1" runat="server" DataSourceID="ObjectDataSource1" > <ItemTemplate> <asp:Label ID="Label1" runat="server" Text='<%# Bind("MyText") %>' /> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("MyText") %>' /> </EditItemTemplate> <InsertItemTemplate> <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("MyText") %>' /> </InsertItemTemplate> </asp:FormView> If I am in Read-Mode or Edit-Mode the control is initialized with the property MyText of the current object which is bound to the FormView. But when I go to Insert-Mode I do not have a "current object" (FormView1.DataItem is indeed null) and the controls are empty. If I want to have my TextBox control initialized with a specific value how can I do that? In which event can I hook in to set default values to the controls in the InsertItemTemplate? Especially I have in mind using an ObjectDataSource. I was expecting that the InsertItemTemplate is initialized with a business object which underlies my ObjectDataSource and which is created by the ASP.NET framework simply by using its default constructor when the InsertItemTemplate gets activated. In the default constructor I would init the class members to the default values I'd like to have in my controls of the InsertItemTemplate. But unfortunately that's not the case: No "default" object is created and bound to the FormView. So it seems I have to initialize all controls separately or to create the default object manually and bind it to the InsertItemTemplate of the FormView. But how and where can I do that? Thanks in advance!
