  • JavaFX - question regarding binding button's disabled state

    - by jamiebarrow
    I'm trying to create a dummy application that maintains a list of tasks. For now, all I'm trying to do is add to the list. I enter a task name in a text box, click on the add task button, and expect the list to be updated with the new item and the task name input to be cleared. I only want to be able to add tasks if the task name is not empty. The below code is my implementation, but I have a question regarding the binding. I'm binding the textbox's text variable to a string in my view model, and the button's disable variable to a boolean in my view model. I have a trigger to update the disabled state when the task name changes. When the binding of the task name happens the boolean is updated accordingly, but the button still appears disabled. But then when I mouse over the button, it becomes enabled. I believe this is due to JavaFX 1.3's binding being lazy - only updates the bound variable when it is read. Also, when I've added the task, I clear the task name in the model, but the textbox's text doesn't change - even though I'm using bind with inverse. Is there a way to make the textbox's text and the button's disabled state update automatically via the binding as I was expecting? Thanks, James AddTaskViewModel.fx: package jamiebarrow; import java.lang.System; public class AddTaskViewModel { function logChange(prop:String,oldValue,newValue):Void { println("{System.currentTimeMillis()} : {prop} [{oldValue}] to [{newValue}] "); } public var newTaskName: String on replace old { logChange("newTaskName",old,newTaskName); isAddTaskDisabled = (newTaskName == null or newTaskName.trim().length() == 0); }; public var isAddTaskDisabled: Boolean on replace old { logChange("isAddTaskDisabled",old,isAddTaskDisabled); }; public var taskItems = [] on replace old { logChange("taskItems",old,taskItems); }; public function addTask() { insert newTaskName into taskItems; newTaskName = ""; } } Main.fx: package jamiebarrow; import javafx.scene.control.Button; import javafx.scene.control.TextBox; import javafx.scene.control.ListView; import javafx.scene.Scene; import javafx.scene.layout.VBox; import javafx.stage.Stage; import javafx.scene.layout.HBox; def viewModel = AddTaskViewModel{}; var txtName: TextBox = TextBox { text: bind viewModel.newTaskName with inverse onKeyTyped: onKeyTyped }; function onKeyTyped(event): Void { txtName.commit(); // ensures model is updated cmdAddTask.disable = viewModel.isAddTaskDisabled;// the binding only occurs lazily, so this is needed } var cmdAddTask = Button { text: "Add" disable: bind viewModel.isAddTaskDisabled with inverse action: onAddTask }; function onAddTask(): Void { viewModel.addTask(); } var lstTasks = ListView { items: bind viewModel.taskItems with inverse }; Stage { scene: Scene { content: [ VBox { content: [ HBox { content: [ txtName, cmdAddTask ] }, lstTasks ] } ] } }

  • set variables in an MVC application?

    - by Melissa
    I am trying to learn about the Orchard MVC application. I see the following code but cannot understand what it is doing. Can someone explain what this: User.As<UserPart>().Record.UserName = value; means? public class UserEditViewModel { [Required] public string UserName { get { return User.As<UserPart>().Record.UserName; } set { User.As<UserPart>().Record.UserName = value; } } [Required] public string Email { get { return User.As<UserPart>().Record.Email; } set { User.As<UserPart>().Record.Email = value; } } public IContent User { get; set; } }

  • I have a question about URI templates in WCF Services

    - by Debby
    I have a web service with following operation contract and my service is hosted at http://localhost:9002/Service.svc/ [OperationContract] [WebGet(UriTemplate = "/Files/{Filepath}")] Stream DownloadFile(string Filepath); This web service would let users download file, if the proper filepath is provided (assuming, I somehow find out that proper filepath). Now, I can access this service from a browser by typing, http://localhost:9002/Service.svc/Files/(Filepath} If {filepath} is some simple string, its not a problem, but I want to send the location of the file. Lets us say users want to download file C:\Test.mp3 on the server. But how can I pass C:\Test.mp3 as {Filepath}? I get an error when I type http://localhost:9002/Service.svc/Files/C:\Test.mp3 in the browser. I am new to web services and find that this community is the quickest way to get answers to my questions.

  • XSD: xs:sequence & xs:choice combination for xs:extension elements?

    - by bguiz
    Hi, My question is about defining an XML schema that will validate the following sample XML: <rules> <other>...</other> <bool>...</bool> <other>...</other> <string>...</string> <other>...</other> </rules> The order of the child nodes does not matter. The cardinality of the child nodes is 0..unbounded. All the child elements of the rules node have a common base type, rule, like so: <xs:complexType name="booleanRule"> <xs:complexContent> <xs:extension base="rule"> ... </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="stringFilterRule"> <xs:complexContent> <xs:extension base="filterRule"> ... </xs:extension> </xs:complexContent> </xs:complexType> My current attempt at defining the schema for the rules node is below. However, Can I nest xs:choice within xs:sequence? If, where do I specify the maxOccurs="unbounded" attribute? Is there a better way to do this, such as an xs:sequence which specifies only the base type of its child elements? <xs:element name="rules"> <xs:complexType> <xs:sequence> <xs:choice> <xs:element name="bool" type="booleanRule" /> <xs:element name="string" type="stringRule" /> <xs:element name="other" type="someOtherRule" /> </xs:choice> </xs:sequence> </xs:complexType> </xs:element>

  • WCF Service with callbacks coming from background thread?

    - by Mark Struzinski
    Here is my situation. I have written a WCF service which calls into one of our vendor's code bases to perform operations, such as Login, Logout, etc. A requirement of this operation is that we have a background thread to receive events as a result of that action. For example, the Login action is sent on the main thread. Then, several events are received back from the vendor service as a result of the login. There can be 1, 2, or several events received. The background thread, which runs on a timer, receives these events and fires an event in the wcf service to notify that a new event has arrived. I have implemented the WCF service in Duplex mode, and planned to use callbacks to notify the UI that events have arrived. Here is my question: How do I send new events from the background thread to the thread which is executing the service? Right now, when I call OperationContext.Current.GetCallbackChannel<IMyCallback>(), the OperationContext is null. Is there a standard pattern to get around this? I am using PerSession as my SessionMode on the ServiceContract. UPDATE: I thought I'd make my exact scenario clearer by demonstrating how I'm receiving events from the vendor code. My library receives each event, determines what the event is, and fires off an event for that particular occurrence. I have another project which is a class library specifically for connecting to the vendor service. I'll post the entire implementation of the service to give a clearer picture: [ServiceBehavior( InstanceContextMode = InstanceContextMode.PerSession )] public class VendorServer:IVendorServer { private IVendorService _vendorService; // This is the reference to my class library public VendorServer() { _vendorServer = new VendorServer(); _vendorServer.AgentManager.AgentLoggedIn += AgentManager_AgentLoggedIn; // This is the eventhandler for the event which arrives from a background thread } public void Login(string userName, string password, string stationId) { _vendorService.Login(userName, password, stationId); // This is a direct call from the main thread to the vendor service to log in } private void AgentManager_AgentLoggedIn(object sender, EventArgs e) { var agentEvent = new AgentEvent { AgentEventType = AgentEventType.Login, EventArgs = e }; } } The AgentEvent object contains the callback as one of its properties, and I was thinking I'd perform the callback like this: agentEvent.Callback = OperationContext.Current.GetCallbackChannel<ICallback>(); How would I pass the OperationContext.Current instance from the main thread into the background thread?

    Hi Guys, I am using C#. I am having below code in C#: protected override void OnInit(EventArgs e) { try { if (Session["boolSignOn"].ToString() == "true".ToString()) { lblPanelOpen.Text = Session["panelOpen"].ToString(); } else { lblPanelOpen.Text = Session["panelOpen"].ToString(); } } catch (Exception ex) { Logger.Error("Error processing request:" + ex.Message); } } protected override void OnLoad(EventArgs e) { try { if (!string.IsNullOrEmpty(Session["panelOpen"].ToString())) { lblPanelOpen.Text = string.Empty; Session.Remove("panelOpen"); } } catch (Exception ex) { Logger.Error("Unable to remove the session variable:" + ex.Message); } } In above code I am having a Session["panelOpen"] variable which is created from another user control and once my page is trying to render, I am storing Session["panelOpen"] in my hidden lblPanelOpen.Text on page OnInit() method, however when page is loaded completely then I am trying to remove the session variable.

  • Why can I not add a set accessor to an overriden property?

    - by Svish
    In a base class I have this property: public virtual string Text { get { return text; } } I want to override that and return a different text, but I would also like to be able to set the text, so I did this: public override string Text { get { return differentText; } set { differentText = value; } } This however does not work. I get a red squiggly under set saying that I can not override because it does not have a set accessor. Why is this aproblem? What should I do?

  • Can Symfony simply reload a page request?

    - by Rob Wilkerson
    I have an app that receives a request from another app. It detects a value on the query string, checks that value against a cached value and, if they don't match, it needs to clear its cache and reload the page (establishing a new cache). Unfortunately, I can't find a way to tell Symfony to redirect to the current page in exactly the same format (protocol, URI path, query string, etc.). What am I missing? This is all happening in a filter on isFirstCall(). Thanks.

  • Problem with jQuery accordion and cookies

    - by rayne
    I have a jQuery accordion from this site and edited for my purposes, but the accordion only works in Firefox (not Safari or Chrome) and the cookies aren't being set correctly. This is the jQuery: function initMenus() { $('#sidebar .letter_index').hide(); $.each($('#sidebar .letter_index'), function() { var cookie = $.cookie(this.id); if (cookie === null || String(cookie).length < 1) { $('#sidebar .letter_index:first').show(); } else { $('#' + this.id + ' .' + cookie).next().show(); } }); $('#sidebar .letter_head').click(function() { var checkElement = $(this).next(); var parent = this.parentNode.parentNode.id; if ((checkElement.is('.letter_index')) && (!checkElement.is(':visible'))) { $('#' + parent + ' .letter_index:visible').slideUp('normal'); if ((String(parent).length > 0) && (String(this.className).length > 0)) { // not working - wie ändert man das this.class so das die class abc oder def gesetzt wird anstatt this?! $.cookie(parent, this.className); } checkElement.slideDown('normal'); return false; } } ); } $(document).ready(function() {initMenus();}); This is how my HTML looks (sample item): <div id="sidebar"> <h2 class="letter_head"><a href="#" class="ABC">ABC</h2> <ul class="letter_index"> <li>Abc</li> <li>Bcd</li> </ul> </div> I can't find the problem why the script won't work in Safari and Chrome. I also don't know how to tell it to use the class of the a inside the h2 as the cookie value. (Currently the cookie is set as $.cookie(parent, this.className);, which produces cookies with the name container (the div above #sidebar) and the value letter_head. It needs to be something like 'sidebar' and 'ABC', 'DEF' and so on. Thanks in advance!

  • Using unicodedata.normalize in Python 2.7

    - by dpitch40
    Once again, I am very confused with a unicode question. I can't figure out how to successfully use unicodedata.normalize to convert non-ASCII characters as expected. For instance, I want to convert the string u"Cœur" To u"Coeur" I am pretty sure that unicodedata.normalize is the way to do this, but I can't get it to work. It just leaves the string unchanged. >>> s = u"Cœur" >>> unicodedata.normalize('NFKD', s) == s True What am I doing wrong?

  • Python: Dynamic attribute name generation without exec() or eval()

    - by PyNewbie27
    Hi, I'm trying to dynamically create buttons at runtime with PyQT4.7 However, this being my first python program I'm not sure how to get the functionality I want. I would like to be able to substitute a text string for an attribute name: i.e. for each in xrange(4): myname = "tab1_button%s" % each #tab1_button0, tab1_button1, tab1_button2 #self.ui.tab1_button0 = QtGui.QPushButton(self.ui.tab) <--normal code to create a named button setattr(self.ui,myname,QtGui.QPushButton(self.ui.tab)) #rewrite of line above to dynamicly generate a button #here's where I get stuck. this code isn't valid, but it shows what i want to do self.ui.gridLayout.addWidget(self.ui.%s) % myname #I need to have %s be tab1_button1, tab1_button2, etc. I know the % is for string substituion but how can I substitute the dynamically generated attribute name into that statement? I assume there's a basica language construct I'm missing that allows this. Since it's my first program, please take it easy on me ;)

  • Using Jquery $getJSON How do I dynamically create data for the [data] parameter after Url param?

    - by Breadtruck
    I have no problems getting the Json to work and parse the json return. I was just wondering how I could build a dynamic "whatever data is" and stick it into [data] to pass my parameters from there and not manually append them to the url. From jquery website example: $.getJSON("test.js", { name: "John", time: "2pm" }, function(json){ alert("JSON Data: " + json.users[3].name); }); I thought I could build a string ( which doesn't make sense anyway ) and drop it inside the { }, but I obviously don't understand that part. name: isn't a string and you can't put a variable in that part, so how would I dynamically put items into whatever [data] is.

  • Mapping child objects in fluent nhibernate to a read-only view

    - by grenade
    Given that I am implementing a read-only UI, how do I create a ClassMap for Shop: public class Shop { public int Id { get; set; } public City City { get; set; } } public class City { public string Name { get; set; } public string CountryCode { get; set; } } The DB interface for Shops is a View containing 3 columns (ShopId, CityName, CountryCode). I was hoping to do something like this: public sealed class ShopMap : ClassMap<Shop> { public ShopMap() { Table("Shop"); Id(x => x.Id, "ShopId"); Map(x => x.City.Name, "CityName"); Map(x => x.City.CountryCode, "CountryCode"); } } Will fluent auto-instantiate Shop.City?

Also I know this can be done with reflections... but it's not the nicest solution to the problem... I'm sort of looking for dynamic features in C#...

I'd like to have a regular expression matches those string that correspond to valid regular expression. Is that possible? Or do I have use some higher level grammar (i.e. context free language) to detect this? Does it affect if I am using some extended version of regexps like Perl regexps? If that is possible, what the regexp matching regexp is?
