  • HTML/CSS - How can I position these nested unordered lists correctly?

    - by Samuroid
    I am looking for some help resolving an issue im having with positioning the following unordered list elements that are contained in a div which has relative positioning: The html structure of the UL: <div id="accountBox" class="account_settings_box"> <ul> <ul> <li class="profileImage"><img src="images/profileimage.jpg" alt="Profile Image" /></li> <li class="profileName">Your name</li> <li class="profileEmail">Your email</li> </ul> <li><a href="">Messages</a></li> <li><a href="">Settings</a></li> <li><a href="">Password</a></li> <li><a href="">Sign out</a></li> </ul> </div> and the CSS for this list: .account_settings_box ul ul { display: inline-block; margin: 0; padding: 0; width: 100%; height: 150px; outline: 1px solid blue; } .account_settings_box ul ul li { display: inline-block; border: none; /* Reset the border */ } .profileImage { float: right; display: block; width: 150px; height: 150px; outline: 1px solid purple; } .profileName, .profileEmail { width: auto; height: auto; width: 150px; height: 150px; } .account_settings_box ul ul li:hover { outline: 1px solid red; } .profileImage img { width: 150px; height: 150px; } I am having difficultly with the embedded ul, i.e, .account_settings_box ul ul element. The image below shows what it currently looks like. I am trying to achieve the follow: Have the image floating to the right, and have the "your name" and "your email" positioned to the left of the image (basically where they are currently). Thanks for your help in advance. Sam :)

  • Trouble with inheritance

    - by Matt
    I'm relatively new to programming so excuse me if I get some terms wrong (I've learned the concepts, I just haven't actually used most of them). Trouble: I currently have a class I'll call Bob its parent class is Cody, Cody has method call Foo(). I want Bob to have the Foo() method as well, except with a few extra lines of code. I've attempted to do Foo() : base(), however that doesn't seem to work like. Is there some simple solution to this?

  • Enumerate registered namespaces of a PHP DOMDocument object

    - by zneak
    Hello world, For one of my projects, I'm using the DOMDocument class to load and manipulate XML documents. I'd need to retrieve every namespace used in the document; however, I can't find how I'd do that. The DOMDocument class has methods to get the namespace prefix of an URI or the URI of a namespace prefix, but I've seen nothing to actually enumerate registered namespaces. The SimpleXML library has a getNamespaces() method for that. Is there an equivalent for DOMDocument?

  • ActionScript 3 and camelcase package name

    - by Paul Dinh
    I'm using Flash Builder 4 to build my AIR application. For a certain reason, I need to declare my package name in camelcase, and class names in lowercase: //test.as package Core { public class test { } } The folder structure is like this (the dir 'Core' matches the package name): src/ Core/ test.as However, Flash Builder shows error and it doesn't compile at all, only when I put the package name as 'core' then it compiles. Does AS3 syntax allow uppercase letters in package name? Or just because Flash Builder implicitly disallows this?

  • jquery delay() doesn't delay attr() in the queue

    - by luca
    hi, what is wrong in this code? I'm trying to get this effect: fadeOut(500) and attr('class','myClass') delayed by 600 millisecs.. then delay(600) again, and fadeIn(500). The delays happen correctly but the attr() is not being delayed, it fires when #myDiv is still fading! :'( $('#myDiv').fadeOut(500).delay(600).attr('class','myClass').delay(600).fadeIn(500); many thanks in advance for any suggestions!

  • CSS selector not resolved when using UI Binder

    - by Zhaidarbek
    Basically, I am building a horizontal navigation bar. I have following markup: <ui:style src="../common.css" type="client.resources.HomeResources.Style"> @external gwt-Anchor; .gwt-Anchor { text-decoration: none; } </ui:style> <g:HTMLPanel styleName="navbar"> <ul> <li><g:Anchor ></g:Anchor> |</li> <li><g:Anchor ></g:Anchor> |</li> <li><g:Anchor ></g:Anchor> |</li> <li><g:Anchor ></g:Anchor> |</li> <li><g:Anchor ></g:Anchor> |</li> <li><g:Anchor ></g:Anchor> |</li> <li><g:Anchor ></g:Anchor></li> </ul> common.css has following rules: ul { margin: 0; padding: 0; text-align: left; font-weight: bold; line-height: 25px; } ul li { display: inline; text-align: right; } ul li a { color: #0077C0; font-size: 12px; margin-right: 15px; padding: 4px 0 4px 5px; text-decoration: none; } ul li a:HOVER { color: #F0721C; } When using rules as defined above, everything works perfect. The problem is that I have ul elements in other parts of page, so I've added div.navbar before each rule like this: div.navbar ul{} div.navbar ul li{} etc... But those rules are not applied to ul elements inside UI Binder template. What's wrong with my code? Here is the generated HTML (normally on one line): <div class="navbar"><ul> <li><a class="gwt-Anchor">Item 1</a> |</li> <li><a class="gwt-Anchor">Item 2</a> |</li> <li><a class="gwt-Anchor">Item 3</a></li> </ul></div> RESOLVED styleName="navbar" must be styleName="{style.navbar}"

  • Windows forms application blocks after station lock

    - by Silviu
    We're having a serious issue at work. We've discovered that after the station where the client was running is locked/unlocked the client is blocked. No repaint. So the UI thread is blocked with something. Looking at the callstack of the UI thread (thread 0) using windbg we see that a UserPreferenceChanged event gets raised. It is marshalled through a WindowsFormsSynchronizationContext using it's controlToSend field to the UI. It gets blocked by a call to the marshalling control. The method called is MarshaledInvoke it builds a ThreadMethodEntry entry = new ThreadMethodEntry(caller, method, args, synchronous, executionContext); This entry is supposed to do the magic. The call is a synchronous call and because of that (still in the MarshaledInvoke of the Control class) the wait call is reached: if (!entry.IsCompleted) { this.WaitForWaitHandle(entry.AsyncWaitHandle); } The last thing that i can see on the stack is the WaitOne called on the previously mentioned AsyncWaitHandle. This is very annoying because having just the callstack of the runtime and not one of our methods being invoked we cannot really point to a bug in our code. I might be wrong, but I'm guessing that the marshaling control is not "marshaling" to the ui thread. But another one...i don't really know which one because the other threads are being used by us and are blocked...maybe this is the issue. But none of the other threads are running a message loop. This is very annoying. We had some issues in the past with marshaling controls to the right ui thread. That is because the first form that is constructed is a splash form. Which is not the main form. We used to use the main form to marshal call to the ui thread. But from time to time some calls would go to a non ui thread and some grids would broke with a big red X on them. I fixed this by creating a specific class: public class WindowsFormsSynchronizer { private static readonly WindowsFormsSynchronizationContext = new WindowsFormsSynchronizationContext(); //Methods are following that would build the same interface of the synchronization context. } This class gets build as one of the first objects in the first form being constructed. We've noticed some other strange thing. Looking at the heap there are 7 WindowsFormsSynchronizationContext objects. 6 of these have the same instance of controlToSend, and the other one has some different instance of controlToSend. This last one is the one that should marshal the calls to the UI. I don't have any other idea...maybe some of you guys had this same issue?

  • MVVM: how to set the datacontext of a user control

    - by EVA
    Hi, I'm writing an application in WPF, using the MVVm toolkit and have problems with hooking up the viewmodel and view. The model is created with ado.net entity framework. The viewmodel: public class CustomerViewModel { private Models.Customer customer; //constructor private ObservableCollection<Models.Customer> _customer = new ObservableCollection<Models.Customer>(); public ObservableCollection<Models.Customer> AllCustomers { get { return _customer; } } private Models.Customer _selectedItem; public Models.Customer SelectedItem { get { return _selectedItem; } } public void LoadCustomers() { List<Models.Customer> list = DataAccessLayer.getcustomers(); foreach (Models.Customer customer in list) { this._customer.Add(customer); } } } And the view (no code behind at the moment): <UserControl x:Class="Customers.Customer" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" xmlns:vm ="clr-namespace:Customers.ViewModels" d:DesignHeight="300" d:DesignWidth="300" xmlns:toolkit="http://schemas.microsoft.com/wpf/2008/toolkit" > <Grid> <toolkit:DataGrid ItemsSource="{Binding AllCustomers}" SelectedItem="{Binding SelectedItem, Mode=TwoWay}" AutoGenerateColumns="True"> </toolkit:DataGrid> <toolkit:DataGrid ItemsSource="{Binding SelectedItem.Orders}"> </toolkit:DataGrid> </Grid> </UserControl> And dataaccesslayer class: class DataAccessLayer { public List<Customer> customers = new List<Customer>(); public static List<Customer> getcustomers() { entities db = new entities(); var customers = from c in db.Customer.Include("Orders") select c; return customers.ToList(); } } The problem is that no data is displayed simply because the data context is not set. I tried to do it in a code-behind but is did not work. I would prefer to do it in a xaml file anyway. Another problem is with the SelectedItem binding - the code is never used. Thanks for help! Regards, EV.

  • How can I resolve circular dependencies in Funq IoC?

    - by Rickard
    I have two classes which I need to reference each other. class Foo { public Foo(IBar bar) {} } class Bar { public Bar(IFoo foo) {} } When I do: container.RegisterAutoWiredAs<Foo, IFoo>(); container.RegisterAutoWiredAs<Bar, IBar>(); and when I try to resolve either interface I get a circular dependency graph which results in an eternal loop. Is there an easy way to solve this in Funq or do you know of a workaround?

  • PyQt threads and signals - how to properly retrieve values

    - by Cawas
    Using Python 2.5 and PyQt, I couldn't find any question this specific in Python, so sorry if I'm repeating the other Qt referenced questions below, but I couldn't easily understand that C code. I've got two classes, a GUI and a thread, and I'm trying to get return values from the thread. I've used the link in here as base to write my code, which is working just fine. To sum it up and illustrate the question in code here (I don't think this code will run on itself): class MainWindow (QtGui.QWidget): # this is just a reference and not really relevant to the question def __init__ (self, parent = None): QtGui.QWidget.__init__(self, parent) self.thread = Worker() # this does not begin a thread - look at "Worker.run" for mor details self.connect(self.thread, QtCore.SIGNAL('finished()'), self.unfreezeUi) self.connect(self.thread, QtCore.SIGNAL('terminated()'), self.unfreezeUi) self.connect(self.buttonDaemon, QtCore.SIGNAL('clicked()'), self.pressDaemon) # the problem begins below: I'm not using signals, or queue, or whatever, while I believe I should def pressDaemon (self): self.buttonDaemon.setEnabled(False) if self.thread.isDaemonRunning(): self.thread.setDaemonStopSignal(True) self.buttonDaemon.setText('Daemon - converts every %s sec'% args['daemonInterval']) else: self.buttonConvert.setEnabled(False) self.thread.startDaemon() self.buttonDaemon.setText('Stop Daemon') self.buttonDaemon.setEnabled(True) # this whole class is just another reference class Worker (QtCore.QThread): daemonIsRunning = False daemonStopSignal = False daemonCurrentDelay = 0 def isDaemonRunning (self): return self.daemonIsRunning def setDaemonStopSignal (self, bool): self.daemonStopSignal = bool def __init__ (self, parent = None): QtCore.QThread.__init__(self, parent) self.exiting = False self.thread_to_run = None # which def will be running def __del__ (self): self.exiting = True self.thread_to_run = None self.wait() def run (self): if self.thread_to_run != None: self.thread_to_run(mode='continue') def startDaemon (self, mode = 'run'): if mode == 'run': self.thread_to_run = self.startDaemon # I'd love to be able to just pass this as an argument on start() below return self.start() # this will begin the thread # this is where the thread actually begins self.daemonIsRunning = True self.daemonStopSignal = False sleepStep = 0.1 # don't know how to interrupt while sleeping - so the less sleepStep, the faster StopSignal will work # begins the daemon in an "infinite" loop while self.daemonStopSignal == False and not self.exiting: # here, do any kind of daemon service delay = 0 while self.daemonStopSignal == False and not self.exiting and delay < args['daemonInterval']: time.sleep(sleepStep) # delay is actually set by while, but this holds for N second delay += sleepStep # daemon stopped, reseting everything self.daemonIsRunning = False self.emit(QtCore.SIGNAL('terminated')) Tho it's quite big, I hope this is pretty clear. The main point is on def pressDaemon. Specifically all 3 self.thread calls. The last one, self.thread.startDaemon() is just fine, and exactly as the example. I doubt that represents any issue. The problem is being able to set the Daemon Stop Signal and retrieve the value if it's running. I'm not sure that it's possible to set a stop signal on QtCore.QtThread, because I've tried doing the same way and it didn't work. But I'm pretty sure it's not possible to retrieve a return result from the emit. So, there it is. I'm using direct calls to the thread class, and I'm almost positive that's not a good design and will probably fail when running under stress. I read about that queue, but I'm not sure it's the proper solution here, or if I should be using Qt at all, since this is Python. And just maybe there's nothing wrong with the way I'm doing.

  • ASP MVC 2: Error with dropdownlist on POST

    - by wh0emPah
    Okay i'm new to asp mvc2 and i'm experiencing some problems with the htmlhelper called Html.dropdownlistfor(); I want to present the user a list of days in the week. And i want the selected item to be bound to my model. I have created this little class to generate a list of days + a short notation which i will use to store it in the database. public static class days { public static List<Day> getDayList() { List<Day> daylist = new List<Day>(); daylist.Add(new Day("Monday", "MO")); daylist.Add(new Day("Tuesday", "TU")); // I left the other days out return daylist; } public class Dag{ public string DayName{ get; set; } public string DayShortName { get; set; } public Dag(string name, string shortname) { this.DayName= name; this.DayShortName = shortname; } } } I really have now idea if this is the correct way to do it Then i putted this in my controller: SelectList _list = new SelectList(Days.getDayList(), "DayShortName", "DayName"); ViewData["days"] = _list; return View(""); I have this line in my model public string ChosenDay { get; set; } And this in my view to display the list: <div class="editor-field"> <%: Html.DropDownListFor(model => model.ChosenDay, ViewData["days"] as SelectList, "--choose Day--")%> </div> Now this all works perfect. On the first visit, But then when i'm doing a [HttpPost] Which looks like the following: [HttpPost] public ActionResult Registreer(EventRegistreerViewModel model) { // I removed some unrelated code here // The code below executes when modelstate.isvalid == false SelectList _list = new SelectList(Days.getDayList(), "DayShortName", "DayName"); ViewData["days"] = _list; return View(model); } Then i will have the following exception thrown: The ViewData item that has the key 'ChosenDay' is of type 'System.String' but must be of type 'IEnumerable<SelectListItem>'. This errors gets thrown at the line in my view where i display the dropdown list. I really have no idea how to solve this and tried several solutions i found online. but none of them really worked. Ty in advance!

  • Need to Release UIWebView Delegate?

    I have a UIWebView named wView. I want to use webViewDidFinishLoad: in my class, so I am setting the class as the delegate for wView by using this line: wView.delegate = self; Everything loads properly, but when I close the UIWebView, the App crashes. If I comment out the wView.delegate = self, it works and does not crash, but then I can't use webViewDidFinishLoad: - any ideas? Do I need to release something?

    I want to create a class, that is flexible so I can switch implementations. Problem: Store files/documents Options: either store locally on the server filesystem, database or etc. Can someone help with a skeleton structure of the class, and how I would call it? I am not using an IoC, and don't really want to just yet. I just want the flexibility where I would make maybe 1 code change in the factory to call another implementation.

  • "Wrapping" a BindingList<T> propertry with a List<T> property for serialization.

    - by Eric
    I'm writing an app that allows users search and browse catalogs of widgets. My WidgetCatalog class is serialized and deserialized to and from XML files using DataContractSerializer. My app is working now but I think I can make the code a lot more efficient if I started taking advantage of data binding rather then doing everything manually. Here's a stripped down version of my current WidgetCatalog class. [DataContract(Name = "WidgetCatalog")] class WidgetCatalog { [DataContract(Name = "Name")] public string Name { get; set; } [DataContract(Name = "Widgets")] public List<Widget> Widgets { get; set; } } I had to write a lot of extra code to keep my UI in sync when widgets are added or removed from a catalog, or their internal properties change. I'm pretty inexperienced with data-binding, but I think I want a BindingList<Widget> rather than a plain old List<Widget>. Is this right? In the past when I had similar needs I found that BindingList<T> does not serialize very well. Or at least the Event Handers between the items and the list are not serialized. I was using XmlSerializer though, and DataContractSerializer may work better. So I'm thinking of doing something like the code below. [DataContract(Name = "WidgetCatalog")] class WidgetCatalog { [DataMember(Name = "Name")] public string Name { get; set; } [DataMember(Name = "Widgets")] private List<Widget> WidgetSerializationList { get { return this._widgetBindingList.ToList<Widget>(); } set { this._widgetBindingList = new BindingList<Widget>(value); } } //these do not get serialized private BindingList<Widget> _widgetBindingList; public BindingList<Widget> WidgetBindingList { get { return this._widgetBindingList; } } public WidgetCatalog() { this.WidgetSerializationList = new List<Widget>(); } } So I'm serializing a private List<Widget> property, but the GET and SET accessors of the property are reading from, and writing to theBindingList<Widget> property. Will this even work? It seems like there should be a better way to do this.

  • How to use imported css styles in GWT correctly

    - by Eduard Wirch
    Imagine you created the following simple widget with UiBinder: <!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent"> <ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" xmlns:g="urn:import:com.google.gwt.user.client.ui"> <ui:style type="my.package.Widget1.Widget1Style"> .childWidgetStyle { border-width: 1px; border-style: dotted; } </ui:style> <g:TextArea styleName="{style.childWidgetStyle}"/> </ui:UiBinder> package my.package; // some imports here public class Widget1 extends Composite { private static Widget1UiBinder uiBinder = GWT.create(Widget1UiBinder.class); interface Widget1UiBinder extends UiBinder<Widget, Widget1> { } public interface Widget1Style extends CssResource { String childWidgetStyle(); } @UiField TextArea textArea; public Widget1(String text) { initWidget(uiBinder.createAndBindUi(this)); textArea.setText(text); } } Than you use this simple widget in another (parent) widget you created: <!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent"> <ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" xmlns:g="urn:import:com.google.gwt.user.client.ui"> <ui:style> .parentWidgetStyle .childWidgetStyle { margin-bottom: 10px; } </ui:style> <g:VerticalPanel ui:field="listPanel" addStyleNames="{style.parentWidgetStyle}" /> </ui:UiBinder> package my.package; // imports go here public class ParentWidget extends Composite { private static ParentWidgetUiBinder uiBinder = GWT.create(ParentWidgetUiBinder.class); interface ParentWidgetUiBinder extends UiBinder<Widget, ParentWidget> { } @UiField VerticalPanel listPanel; public ParentWidget(final String... texts) { initWidget(uiBinder.createAndBindUi(this)); for (final String text : texts) { final Widget1 entry = new Widget1(text); listPanel.add(entry); } } } What you want to achieve is to get some margin between the Widget1 entries in the list using css. But this won't work. Because GWT will obfuscate the css names. And the obfuscated name for .childWidgetStyle in ParentWidget will be different from the .childWidgetStyle in Widget1. The resulting css will look similar to this: .G1unc9fbE { border-style:dotted; border-width:1px; } .G1unc9fbBB .G1unc9fDa { margin-bottom:10px; } So the margin setting wont apply. How do I do this correctly?

  • Problem with JSON, Struts 2 and Ajax.

    - by Javi
    Hello, I have an apllication with Struts 2, Spring and I want to send JSON as a response to an Ajax request, but my server in not sending the JSON in the response. I have this base package: <package name="myApp-default" extends="struts-default"> <result-types> <result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" /> <result-type name="json" class="com.googlecode.jsonplugin.JSONResult"> <param name="enableGZIP">true</param> <param name="noCache">true</param> <param name="defaultEncoding">ISO-8859-1</param> </result-type> </result-types> </package> And another package which extends the previous one. <package namespace="/rest" name="rest" extends="myApp-default"> <action name="login" class="restAction" method="login"> <result type="json"/> </action> So I call with jQuery Ajax and debugging it I see it enters in the Action restAction in the method login and it also enters in the method getJsonData() because I have set two breakpoints and the program is stopped first in login and then in getJsonData. public class RestAction extends BaseAction { private String login; private String password; private String jsonData; public String login() { jsonData = "changed"; return Action.SUCCESS; } //I ommit getter/setters for login and password @JSON(name="jsonData") public String getJsonData() { return jsonData; } public void setJsonData(String jsonData) { this.jsonData = jsonData; } } My ajax looks like this: $.ajax({type: 'GET', url: this_url, data: pars, cache:false, success: handleResponse, error: handleError}); With firebug I see that the response to my request is completely void (though I have seen that the data saved in pars variable has been populated to the action and the methods have been executed correctly). And maybe for that reason my ajax enters in my handleError function where xmlHttpRequest.readyState is 4 and xmlHttpRequest.status is 0. Can anyone tell me what may the problem be? Thanks.

  • Flex+JPA/Hibernate+BlazeDS+MySQL how to debug this monster?!

    - by Zenzen
    Ok so I'm making a "simple" web app using the technologies from the topic, recently I found http://www.adobe.com/devnet/flex/articles/flex_hibernate.html so I'm following it and I try to apply it to my app, the only difference being I'm working on a Mac and I'm using MAMP for the database (so no command line for me). The thing is I'm having some trouble with retrieving/connecting to the database. I have the remoting-config.xml, persistance.xml, a News.java class (my Entity), a NewsService.java class, a News.as class - all just like in the tutorial. I have of course this line in one of my .mxmls: <mx:RemoteObject id="loaderService" destination="newsService" result="handleLoadResult(event)" fault="handleFault(event)" showBusyCursor="true" /> And my remoting-config.xml looks like this (well part of it): <destination id="newsService"> <properties><source>com.gamelist.news.NewsService</source></properties> </destination> NewsService has a method: public List<News> getLatestNews() { EntityManagerFactory emf = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT); EntityManager em = emf.createEntityManager(); Query findLatestQuery = em.createNamedQuery("news.findLatest"); List<News> news = findLatestQuery.getResultList(); return news; } And the named query is in the News class: @Entity @Table(name="GLT_NEWS") @NamedQueries({ @NamedQuery(name="news.findLatest", query="from GLT_NEWS order by new_date_added limit 5 ") }) The handledLoadResult looks like this: private function handleLoadResult(ev:ResultEvent):void { newsList = ev.result as ArrayCollection; newsRecords = newsList.length; } Where: [Bindable] private var newsList:ArrayCollection = new ArrayCollection(); But when I try to trigger: loaderService.getLatestNews(); nothing happens, newsList is empty. Few things I need to point out: 1) as I said I didn't install mysql manually, but I'm using MAMP (yes, the server's running), could this cause some trouble? 2) I already have a "gladm" database and I have a "GLT_NEWS" table with all the fields, is this bad? Basically the question is how am I suppose to debug this thing so I can find the mistake I'm making? I know that loadData() is executed (did a trace()), but I have no idea what happens with loaderService.getLatestNews()... @EDIT: ok so I see I'm getting an error in the "fault handler" which says "Error: Client.Error.MessageSend - Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Status 404: url: 'http://localhost:8080/WebContent/messagebroker/amf' - "
