  • Add Hover display for table cell

    - by Jake
    I have a table, but it is not in a list format, meaning not a column/row format. I look for specific cells to add a hover event that displays a description of the cell. $("#TableID td").hover(function(){ //ifCellThatIWant $(this).append("<span>Message that was brought in</span>"); }, function(){ $(this).children().remove(); }); The problem is right now is that the hover displays a span(with info. inside) that I used jquery to append the span to the cell when mouseover, which expands the cell, which is an effect that I don't like or want. I'm Trying to have an out of the table look,but still be by the cell that triggered the event; because if the span has a lot of info. in it, expanding the cell dynamically will start to look pretty nasty. Also will help if I had some type of css direction on how will I make the display for the mouseover "description" span look nice. My mind thought is that a way to accomplish what I want is giver the appended span the position of my mouse cursor when hover, but not sure if its the right approach or what the syntax would look like.

    - by pal25
    Hi, We are in search of an automated testing tool for our project. As we are in testing department we prefer a tool which would have less programming in it. Please suggest some tools for us .Till now we are testing our application manually. Our project is being developed in Java. Is there any freeware tool that I could use or is it better to go for a paid tool? Thanks in Advance.

  • Transitioning from the web to the desktop

    - by Paul Anderssen
    Can anyone recommend a language, library, framework or book which focuses on GUI programming from the perspective of a web developer? I have experience in web development, for example HTML/AJAX/PHP/MySQL among similar technologies. However, I have never programmed my own back-end, or any kind of standalone program. Does anyone have experience making this transition, and what would I best study to help make the leap from the browser to creating programs with GUIs (primarily for Windows)?

  • Please Describe Your Struggles with Minimizing Use of Global Variables

    - by MetaHyperBolic
    Most of the programs I write are relatively flowchartable processes, with a defined start and hoped-for end. The problems themselves can be complex but do not readily lean towards central use of objects and event-driven programming. Often, I am simply churning through great varied batches of text data to produce different text data. Only occasionally do I need to create a class: As an example, to track warnings, errors, and debugging message, I created a class (Problems) with one instantiation (myErr), which I believe to be an example of the Singleton design pattern. As a further factor, my colleagues are more old school (procedural) than I and are unacquainted with object-oriented programming, so I am loath to create things they could not puzzle through. And yet I hear, again and again, how even the Singleton design pattern is really an anti-pattern and ought to be avoided because Global Variables Are Bad. Minor functions need few arguments passed to them and have no need to know of configuration (unchanging) or program state (changing) -- I agree. However, the functions in the middle of the chain, which primarily control program flow, have a need for a large number of configuration variables and some program state variables. I believe passing a dozen or more arguments along to a function is a "solution," but hardly an attractive one. I could, of course, cram variables into a single hash/dict/associative array, but that seems like cheating. For instance, connecting to the Active Directory to make a new account, I need such configuration variables as an administrative username, password, a target OU, some default groups, a domain, etc. I would have to pass those arguments down through a variety of functions which would not even use them, merely shuffle them off down through a chain which would eventually lead to the function that actually needs them. I would at least declare the configuration variables to be constant, to protect them, but my language of choice these days (Python) provides no simple manner to do this, though recipes do exist as workarounds. Numerous Stack Overflow questions have hit on the why? of the badness and the requisite shunning, but do not often mention tips on living with this quasi-religious restriction. How have you resolved, or at least made peace with, the issue of global variables and program state? Where have you made compromises? What have your tricks been, aside from shoving around flocks of arguments to functions?

  • JavaScript Key Codes

    - by Jonathan Wood
    I'm working with a JavaScript routine I didn't write. It is called from a text box's onkeydown attribute to prevent unwanted keystrokes. The first argument is apparently not used. The second argument is a list of characters that should be allowed. function RestrictChars(evt, chars) { var key; var keychar; if (window.event) key = window.event.keyCode; else if (e) key = e.which; else return true; keychar = String.fromCharCode(key); if ((key == null) || (key == 0) || (key == 8) || (key == 9) || (key == 13) || (key == 27)) // Control key return true; else if (((chars).indexOf(keychar) > -1)) return true; else return false; } This seems to work for alpha-numeric characters. However, characters such as . and / cause this function to return false, even when these characters are included in the chars parameter. For example, if the . key is pressed, key is set to 190, and keychar gets set to the "3/4" character. Can anyone see how this was meant to work and/or why it doesn't? I don't know enough about JavaScript to see what it's trying to do.

  • Which IDE / code editor was the first to introduce a code completion feature?

    - by Uri
    I am trying to identify the point in time where code completion (autocomplete/intellisense/whatever) was first introduced in IDEs and would appreciate any pointers. By code completion here I mean a feature within the editor that offers methods or suggestions based on the code that was already typed, and I am interested in programming language related completions (not word processor style completion).

  • Jquery - removing an image before the client browser attempts to download it

    - by ajbrun
    Hi there, I wonder if anyone could help me with a problem I've been having. I have a number of large images available, but due to space limitations, I can't create multiple copies of these at various sizes. I have used PHP GD functions to resize the images to the sizes I need and output them to the browser. This works, but obviously takes some processing time, which therefore impacts pages load times. I'm fine with this, but I only want to show the image once it's fully loaded, and have a loading gif in its place until that time. I'm using jquery to do this. The problem I'm having is making the page functional whether the client has javascript enabled or not. If JS is not enabled, I want standard img tags to be outputted, otherwise the images are removed and replaced with a loading gif until they have been fully loaded. The link below shows a simple non-javascript unfriendly example of a what I want to do (try turning JS off): http://jqueryfordesigners.com/demo/image-load-demo.php I've been testing the basics using the code below. The attr() function will be replaced with something like remove(). This is just a test to make something happen to the image before the browser tries to load it. $(document).ready(function() { $( "#Thumbnails .thumbnail img" ).attr('src', '#'); }); In IE, this works correctly - the image source is replaced with "#" BEFORE the client browser gets a chance to start downloading the image. In firefox however, it downloads the image, and THEN changes the source. It seems to me that firefox is loading the jquery onready event later than it should. As far as I know, this should be executed before the standard onload event and before anything has started loading. If it helps, I'm testing it with a good number of images on screen (81). Am I doing something wrong?

  • Can I get away with this or is it just too crude and unpractical ?

    - by The_AlienCoder
    I spent the whole of last night searching for a free AspNet web chat control that I could simply drag into my website. Well the search was in vain as I could not find a control that matched my needs i.e List of users, 1 to 1 chat, Ability to kick out users.. In the end I decided to create my own control from scractch. Although it works well on my machine Im concerned that It maybe a little crude and unpractical on a shared hosting enviroment. Basically this is what I did : Created an sql database that stores the chat messages. Wrote the stored procedures and and included a statement that clears old messages Then the 'crude' part : Dragged an update panel and timer control on my page Dragged a Repeater databound to the chat messages table inside the update panel Dragged another update panel and inside it put a textbox and a button Configured the timer control to tick every 5 seconds. ..and then I made it all work like this In the timer tick event I 'refreshed' the messages display by invoking Databind() on my repeater i.e protected void Timer1_Tick(object sender, EventArgs e) { MyRepeater.DataBind(); } Then in my send button click event protected void btnSend_Click(object sender, EventArgs e) { MyDataLayer.InsertMessage(Message, Sender, CurrTime); } Well It works well on my machine and Ive got the other functionalities(users list, kick out user..) to work by simply creating more tables. But like I said it seems a little crude to me. so I need a proffesional opinion. Should I run with this or try another Approach ?

  • Hiernate's version values in Grails app

    - by xain
    Hi, looking at a database dump file, and I see many records in various tables with their version number set in values other than 0 (even 94 in one case). I understand it has to do with hibernate locking strategy, but my concern is that today is Sunday, and the site has almost no visitors so is: is this normal ? Or is there a known hibernate bug or even some programming malpractice producing this ? Thanks in advance.

  • actionscript 3 website load movieclips (frames) from library

    - by steve
    Here is my current code that doesn't function: import flash.display.*; import fl.transitions.*; import flash.events.MouseEvent; stop(); var contentBox:MovieClip = new MovieClip(); contentBox.width = 400; contentBox.height = 500; contentBox.x = 400; contentBox.y = 0; var closeBtn:close_btn = new close_btn(); closeBtn.x = 850; closeBtn.y = 15; var bagLink:MovieClip = new bag_link_mc(); bagLink.x = 900; bagLink.y = 0; menu_bag_button.addEventListener(MouseEvent.CLICK, bagClick); function bagClick(event:MouseEvent):void{ if(MovieClip(root).currentFrame == 835) { } else { MovieClip(root).addChild (contentBox); MovieClip(root).contentBox.addChild (bagLink); MovieClip(root).contentBox.addChild (closeBtn); MovieClip(root).gotoAndPlay(806); } } closeBtn.addEventListener(MouseEvent.CLICK, closeBag); function closeBag (event:MouseEvent):void{ MovieClip(root).removeChild(contentBox); MovieClip(root).gotoAndPlay(850); } I don't know ActionScript at all, so this may be the complete wrong way of approaching it. The setup is as follows: site loads, there's a big menu in the center (frame 805). When you click on a menu item from there, the whole menu moves to the side, and the right side I want a "contentBox" movieclip, filled with "bagLink" (which is site content) and to have a close button (closeBtn.) It also needs to know that if you click the same link again on the left side that it doesn't reanimate, it just stays (which I achieved with the "if" statement.) Finally, if someone clicks another link, it needs to clear "contentBox" and refill it with whatever movieClip that was clicked. I know this is a lot to ask, but I'm in dire need of help as this is due on Wednesday...

  • Why am I needing to click twice on a WPF listbox item in order to fire a command?

    - by Donal
    Hi, I'm trying to make a standard WPF listbox be dynamically filled, and for each item in the list box to launch a command when clicked. Currently I have a working listbox, which can be filled and each item will fire the correct command, but in order to fire the command I have to click the list item twice. i.e, Click once to select the item, then click on the actual text to fire the command. As the list is dynamically created, I had to create a data template for the list items: <ListBox.ItemTemplate> <DataTemplate> <TextBlock Margin="4,2,4,2"> <Hyperlink TextDecorations="None" Command="MyCommands:CommandsRegistry.OpenPanel"> <TextBlock Text="{Binding}" Margin="4,2,4,2"/> </Hyperlink> </TextBlock> </DataTemplate> </ListBox.ItemTemplate> Basically, how do I remove the need to click twice? I have tried to use event triggers to fire the click event on the hyperlink element when the list box item is selected, but I can't get it to work. Or, is there a better approach to dynamically fill a listbox and attach commands to each list item? Thanks

  • help to reiterate through my jquery snippet

    - by s2xi
    Code in question: $("#alpha").click(function(event) { event.preventDefault(); $("#show").slideToggle(); }); I have a list of files and its being outputted with PHP in alphabetical. I use this method in PHP: foreach(range('A','Z') as $i) { if (array_key_exists ("$i", $alpha)) { echo '<div id="alpha"><a href="#" name="'.$i.'"><h2>'.$i.'</h2></a></div><div id="show">'; foreach ($$i as $key=>$value) echo '<p>'.$value.' '.$key.'</p>'; } echo '</div>'; } What I want to do is when the user clicks on the #alpha to toggle the div #show that has the names that belong to a letter up. I can do this with the first listing, but every listing after that isn't affected. how can i tell jquery that foreach letter apply the js code so it can toggle up/down the #show. I don't want to this 26 times (one time for each letter in the alphabet), I tried to use class instead of id but that causes all the #show to toggleup heh.

  • Flex 4: Scale to a point (zoom into an image where the mouse was clicked)

    - by Jason W
    I've been trying to get this working and I can't seem to figure it out. There is an Image control that when I click on it I need to zoom in (using the center/transform point where the mouse is clicked). I have the zoom transition working great, but when I set transformX & tranformY (with autoCenterTransform false) it doesn't zoom into that point. Here is my code that only zooms in (not to a specific point) <fx:Script> <![CDATA[ protected function imgLogo_clickHandler(event:MouseEvent):void { transformer.play(); } ]]> </fx:Script> <fx:Declarations> <s:Parallel id="transformer" target="{imgLogo}"> <s:Scale scaleXBy="0.5" scaleYBy="0.5" /> </s:Parallel> </fx:Declarations> <mx:Image id="imgLogo" width="250" x="100" y="100" maintainAspectRatio="true" source="@Embed('src/logo.png')" click="imgLogo_clickHandler(event)" /> Any help is greatly appreciated. Thanks

    I am not sure if you can post revision programming questions in here but i am stuck with some algorithms revision If an algorithm is quadratic it takes time proportional to the number of n^2 ? So if the slides say its almost 1/2 the square of n records is this the same as saying (n^2 * 0.5) Thanks

  • Understanding Scope on Scala's For Loops (For Comprehension)

    - by T. Stone
    In Chapter 3 of Programming Scala, the author gives two examples of for loops / for comprehensions, but switches between using ()'s and {}'s. Why is this the case, as these inherently look like they're doing the same thing? Is there a reason breed <- dogBreeds is on the 2nd line in example #2? // #1 ()'s for (breed <- dogBreeds if breed.contains("Terrier"); if !breed.startsWith("Yorkshire") ) println(breed) // #2 {}'s for { breed <- dogBreeds upcasedBreed = breed.toUpperCase() } println(upcasedBreed)
