  • Can jQuery UI's Sortable handle complex selectors for the items option?

    - by jverdi
    I have list items in an unordered list that when double clicked, can be edited in place via a wysiwyg editor. $('ul.mtm_section').sortable({ disabled: true, distance: 10, items: '> li:not(:has(form))' }); My goal is to prevent the list item from being sorted while it is being edited - aka once a form element has been swapped in place of the contents. Unfortunately my selector for items is not working. Is sortable able to handle complex selectors like these? If not, are there other clever means to disable some items from being sortable, perhaps a callback function? I would prefer to rely on this sortable option, as the wysiwyg plugin is deeply nested with jEditable and as far as I know does not open up any events for me to hook into. Using jQuery 1.4.2 and jQuery UI 1.8.1

  • ANTLR - Embedding Java code, evaluate before or after?

    - by wvd
    Hello all, I'm writing a simple scripting language on top of Java/JVM, where you can also embed Java code using the {} brackets. The problem is, how do I parse this in the grammar? I have two options: 1] Allow everything to be in it, such as: [a-z|a-Z|0-9|_|$], and go on 2] Get an extra java grammar and use that grammar to parse that small code (is it actually possible and efficient?) Since option 2] is basically a double-check since when evaluating java code it's also being checked. Now my last question is -- is way that can dynamically execute java code also with objects which have been created at runtime? Thanks, William van Doorn

  • multiple C++ deletion of a memory pointed by multiple objects

    - by elgcom
    Another c++ pointer deletion question is in the following example: class Foo { public: int *p; ~Foo() { delete p; p = NULL; } }; Foo *f1 = new Foo(); Foo *f2 = new Foo(); f1->p = new int(1); f2->p = f1->p; delete f2; // ok delete f1; // no error? Why I did not get error when calling "delete f1"? didn't I delete the same address (*p) twice? If I directly delete the pointers in the last 2 lines of code, I will get error. delete f2->p; // ok delete f1->p; // error!! *** glibc detected *** double free or corruption (fasttop) ***

  • Find the right parameters for an event without using Design Mode in Visual Studio 2010

    - by Jason
    Is there a way to know what parameters are needed by an event in Visual Studio 2010? Let's say I have a DropDownList control and I want to bind a method to the "OnSelectedIndexChanged", I would do something like this In the ASPX File: <asp:DropDownList ID="lstMyList" runat="server" OnSelectedIndexChanged="lstMyList_SelectedIndexChanged"></asp:DropDownList> In the codebehind: protected void lstMyList_SelectedIndexChanged(object sender, EventArgs e) { ... } Is there a way to know what parameters the method needs? (In this case, an object for the sender and an EventArgs parameter for the event.) I know you can easily create the method by double-clicking the right event in Design Mode, but it does a mess with your code so I prefer not to use it. Thanks!

  • How to call an event when the user "finally" selects an item in a list?

    - by herzmeister der welten
    When a user clicks once on an item in a Grid or a ListBox, that item is usually selected, hence most UI frameworks have a onSelected event or the like for that. However, how can we generally call the next step when a user "finally" selects an item by e.g. double clicking an entry? You know when some popup might appear in the context of the selected item and the user can do further stuff. Strangely enough, I think I have never seen a word for that in any UI framework. onPicked, onAccepted, onChosen, onFinallySelected, onResult? All kinda awkward or too special. Any other ideas?

  • VSTO addin (2003-2007) Ms Word & Webservices

    - by Daveo
    Hi, I am planning on starting my 1st VSTO project. What I want to be able to do is: Download and Upload versions of a MS Word document to a web service. With authentication by overriding the save button Call a web service to list a bunch of tag that can be inserted into a document. When a user double clicks a tag the selected tag is inserted into the cursor position. I am pretty sure this is all possible just want some confirmation? Also would like to know how long would it take to make something like this. I think the biggest issue will be authentication and listing exiting files to download then allowing the user to download a .doc and restore previous versions of that file via the web service.

  • Passing parameters into ViewModels (Prism)

    - by vXtreme
    Hi I can't figure out how to pass parameters to my viewmodels from other views or viewmodels. For instance, I have a View called Customers. There is a grid inside, and if you double-click the grid, a new view is supposed to come up and allow you to edit that customer's data. But how will the View(Model) responsible for editing data know which customer it's supposed to open if I can't pass any parameters inside? EventAggregator is out of the question because I obviously can't create hundreds of eventargs, each for one view. And besides, it's a lousy solution. So far I was able to come up with: CustomerDataView custView = new CustomerDataView(customerId, currentContext); manager.Regions[RegionNames.Sidebar].AddAndActivate(custView); What do you think about this particular solution? Is this the way it's normally done? What I don't like about this is the fact that I lose out on automatic dependency injection by Unity.

  • php $_REQUEST data is only half-decoded

    - by hackmaster.a
    I am retrieving a url via querystring. I need to pass it again to the next page. When I retrieve it the first time, using $_REQUEST['url'], only the slashes are decoded, e.g: http://example.com/search~S10?/Xllamas&searchscope=10&SORT=D/Xllamas&searchscope=10&SORT=D&SUBKEY=llamas/51%2C64%2C64%2CB/browse The php docs page for urldecode advises against decoding request data, and says that it will already be decoded. I need it either completely decoded, so I can encode it again without double-encoding some parts, or not decoded at all. I'm not sure why my experience of this data is incongruous with the php docs. Appreciate any help or pointers to same!!

  • Java Programming Homework

    - by user1427476
    Write a program to read in a file containing the names of the employ of a company and store them in an array of Strings named Employ []. Read another file containing the Salaries of each employ written in the same order and store them in another array of integers named salary[] (contents of both files are shown below). Finally create a file stating for example. Mr. XYZ receive $75,500.00 per year (Note that salary is stored as integer but displayed here as double with a comma separating thousands. This formatting needs to be done using DecimalFormat Class)

  • Java - Could not find the main class?

    - by asmo
    I'm having a hard-time with a Java error. I'm getting this when double-clicking on my compiled project Jar file in order to run it: Could not find the main class: testPackage.testFrame. Program will exit. However, my main class is cleary defined in the project properties. Furthermore, everything works fine when I run the project directly from NetBeans. I'm using the ip2c.jar third-party library to determine countries from IP addresses. If I comment the class that is using the ip2c.jar file, I don't get the error. How can a third-party library be preventing the JVM from finding my main class?

  • Stacking a View with the Editor Area?

    - by Patrick
    Hello everybody, :-) Is it possible, when developing an Eclipse RCP Application, to stack a view with the editor area? Like this? http://www.fotos-hochladen.net/stackingaviewwithane9e1fdbvp.png I have multiple lists / tables. I want to create a kind of preview composite. When an Item on a list is selected by single mouse click, i want my preview composite to show the data of the item. If the user double clicks an item, i want to open an editor in the stack behind the preview composite. Is there anyway to achieve this? Thanks Patrick :-)

  • How to create a win32 application without window in background with C?

    - by user563413
    The application do not need any window or console. It can be a console application if the console window can be removed or can be put into background. The application will do some simple tasks(such as cleaning rubbish files) and exit. I hope that the application should not be a windows service if possible. I hope that the application can be started with double-click in explorer window and run silently. When the application is running, I hope that the mouse cursor should not be changed to hourglass shape. That is to say, do not disturb the user when the application is running. Just run and exit silently. DO NOT NEED to run it when windows starts or user logins. I hope this can be done in C if possible. What should I do? Thanks!

  • C++ initializing constants and inheritance

    - by pingvinus
    I want to initialize constant in child-class, instead of base class. And use it to get rid of dynamic memory allocation (I know array sizes already, and there will be a few child-classes with different constants). So I try: class A { public: const int x; A() : x(0) {} A(int x) : x(x) {} void f() { double y[this->x]; } }; class B : A { B() : A(2) {} }; Pretty simple, but compiler says: error C2057: expected constant expression How can I say to compiler, that it is really a constant?

  • Is incrementing in a loop exponential time?

    - by user356106
    I've a simple but confusing doubt about whether the program below runs in exponential time. The question is : given a +ve integer as input, print it out. The catch is that you deliberately do this in a loop, like this: int input,output=0; cininput; while(input--) ++output; // Takes time proportional to the value of input cout<< output; I'm claiming that this problem runs in exponential time. Because, the moment you increase the # of bits in input by 1, the program takes double the amount of time to execute. Put another way, to print out log2(input) bits, it takes O(input) time. Is this reasoning right?

  • IntelliJ: Including jars in a jar artifact

    - by skiaddict1
    Developing on the Mac with IntelliJ 9.0.2. I have a program which depends on two library jars. I have figured out how to get IntelliJ to make me a jar of my source (with the Artifact tab), and even to include the two jars in it. However, if I get a listing of the jar file it produces, it looks like this: com/acme/MyClass1.class com/acme/MyClass2.class ... mylib1.jar myLib2.jar And, no surprises, if I double-click the jar file, it gets a NoClassDefFoundError the first time it tries to access a class in one or other library jar. How do I get IntelliJ to include the two library jars such that the classes are visible?

  • Set focus to another control after TreeView click

    - by Chintan Shah
    I have a TreeView control in a Windows application. I am opening another window from the TreeView click (Single Click) event (in tabbed environment, so all windows will appear as a tab in Visual Studio). I want to set focus to one control of the new window. The problem is that, I am able to set the focus on the double click event of the TreeView. But same doesn't seem to be working with the TreeView single-click event. Any workarounds?

  • uitextfield delegate must be file's owner?

    - by deafgreatdane
    I've seen a few references (eg here) in response to folks having trouble getting the keyboard to dismiss in iPhone that say "double check that the delegate is attached to file's owner. Is this necessarily true? Or just standard practice? Can't I have other objects in my nib, such as a subclass of UIViewController, and make connections to those as I like? I'd hate to have to route everything into the object that happens to be file owner. That said, I'm having a difficult time getting the keyboard to disappear. I know it's connected to the delegate, because I can set break points and step through the code. I can see the [theTextField resignFirstResponder] get called (and return true), but the keyboard still won't go away. Any other suggestions?

  • How to make a cell of TAdvStringGrid editable?

    - by ammu
    I am trying to implement a filter using the component TAdvStringGrid. My requirement is that I want the first row of this component to be editable when double clicked, so that the user can filter data. Borland C++ Builder is used to help achieve this task. I found this event OnCanEditCell. TCanEditCellEvent = procedure (Sender:TObject;Arow,Acol:longint;var canedit:boolean) of object; Within this function I've set canedit = true. This doesn't seem to work. Probably I need to do something more. I am new to Windows and GUI development. So any help would be great. Do I need to call this function from the OnDblClickCell event? How can I get it working? Thanks in advance

  • drawImage in Java applet flickers in Safari

    - by lcvinny
    I'm having a flicker problem in a Java applet in Safari (Mac). However, it's not the usual double buffering problem. I have isolated it down to one single drawImage call (no redundant repaint, no clear is called), which gives a white flicker before painting the image but not on every repaint. In fact, I measured the duration of the drawImage call, which is normally about 1ms, but up to 30ms about every 5th time paint is called, which is when it flickers. Repaints are triggered when I drag a component or when the window is scrolled. Is this a bug in the java implementation on OSX, and is there a fix for it?

  • Why for only some actions must I call setTarget?

    - by Max Pierce
    For most actions, I just click and drag in InterfaceBuilder to "wire up" a call from some interface object to my code. For example, if I want to know when the user single-clicks a row in a table, I drag a connection from the table's action to my controller's action. But now let's consider the user double-clicking a row. If I want one of my actions to be called when this happens, I need to call not only -[NSTableView setDoubleAction] but also -[NSControl setTarget]. Why? To be clear, I am not asking why Interface Builder doesn't support setDoubleAction. All tools have limitations. I am trying to gain a greater understanding about how and why setTarget doesn't seem to be necessary unless and until I want setDoubleAction to work. Another way to ask this question would be: Why don't I need to do anything in Interface Builder to set the target of the table's (single-click) action?
