  • Can I add elements to a Java GUI?

    - by Asj
    I want to know how I can make a java program where an unknown amount of objects can be added to a GUI depending on user input. I can program in objects one at a time within the program, but I haven't seen a more dynamic program. Can I do that with Java? If not, what can I do it with? For more information, here's a picture. http://i6.photobucket.com/albums/y223/Asj127/CapProjIdea.jpg There can be more than one question per question block, and each question can have it's own question block.

  • Wrapping Multiple Elements (jQuery)

    - by Nimbuz
    I've this piece of HTML: div.content div.one content div.two content div.three content I want to add two divs on top and bottom and wrap one div around it so it becomes: div.top div.wrapper div.content div.one content div.two content div.three content div.bottom I'm aware of the several wrap selectors (innerWrap, wrapAll etc..) but I'm not sure how to wrap 2 divs. The following jQuery might work, but is there a better way to write it? $('content').wrap('<div class="wrapper"></div'); $('.wrapper').before('<div class="top"></div>'); $('.wrapper').after('<div class="bottom"></div>');

  • Creating Settings form using TreeView in C#

    - by Kiran Chandrashekhar
    I am developing the settings form for the software developed in C#. I was looking at how different software have implemented their settings form. In most of the cases that I came across, they seem to be using Treeview on the left pane of the form and configuration settings on the right pane. Ref URL : http://2.bp.blogspot.com/-nMfQoLurxwM/UDXfiZKd4DI/AAAAAAAAAME/IRf6kmxay4w/s1600/bild1.jpg I was wondering, how the different controls are designed/displayed on the right pane. Do they hide all the controls depending which node is selected in the TreeView something like this : if (treeView1.SelectedNode == treeView1.Nodes[0]) { this.groupBox1.Visible = true; this.button1.Visible = true; this.textBox1.Visible = true; this.textBox2.Visible = true; this.label1.Visible = true; this.label2.Visible = true; this.label3.Visible = true; } else { this.groupBox1.Visible = false; this.button1.Visible = false; this.textBox1.Visible = false; this.textBox2.Visible = false; this.label1.Visible = false; this.label2.Visible = false; this.label3.Visible = false; this.groupBox2.Visible = true; this.button2.Visible = true; this.textBox3.Visible = true; this.textBox3.Visible = true; this.labe4.Visible = true; this.label5.Visible = true; this.label6.Visible = true; // bool success = selectColor(); } Is my understanding correct ? Or do we have a better design approach for creating a settings form. Thanks

  • IE7 & 8 not fireing jQuery click events for elements appended inside a table

    - by Keith
    I have an IE bug that I'm not sure how to fix. Using jQuery I'm dynamically moving a menu to appear on an element on mouseover. My code (simplified) looks something like this: $j = jQuery.noConflict(); $j(document).ready(function() { //do something on the menu clicks $j('div.ico').click(function() { alert($j(this).parent().html()); }); setUpActions('#tableId', '#menuId'); }); //on mouseover set up the actions menu to appear on mouseover function setUpActions(tableSelector, menuSelector) { $j(tableSelector + ' div.test').mouseover(function() { //note that append will move the underlying //DOM element with all events from it's old //parent to the end of this one. $j(this).append($j(menuSelector).show()); }); } This menu doesn't seem to register events correctly for the menu after it's been moved in IE7, IE8 and IE8-as-IE7 (yeah MS, that's really a 'new rendering engine' in IE8, we all believe you). It works as expected in everything else. You can see the behaviour in a basic demo here. In the demo you can see two examples of the issue: The image behind the buttons should change on hover (done with a CSS :hover selector). It works on the first mouseover but then persists. The click event doesn’t fire – however with the dev tools you can manually call it and it is still subscribed. You can see (2) in IE8's dev tools: Open page in IE8 Open dev tools Select "Script" tab and "Console" sub-tab Type: $j('#testFloat div.ico:first').click() to manually call any subscribed events There will be an alert on the page This means that I'm not losing the event subscriptions, they're still there, IE's just not calling them when I click. Does anyone know why this bug occurs (other than just because of IE's venerable engine)? Is there a workaround? Could it be something that I'm doing wrong that just happens to work as expected in everything else?

  • jQuery selectable() elements update values

    - by Josh
    Basically what I'm trying to do is update the value attribute of a hidden input field contained within the selected element when the selectable() UI stops running. If the element is selected, then the input's value should be the name attribute of that particular LI, whereas if the element is not selected, the value should be updated as empty. HTML Sample: <ul id="selector"> <li class="networkicon shr-digg" name="shr-digg"> <div></div> <label>Digg</label> <input type="hidden" value="" name="bookmark[]" /> </li> <li class="networkicon shr-reddit" name="shr-reddit"> <div></div> <label>Reddit</label> <input type="hidden" value="" name="bookmark[]" /> </li> <li class="networkicon shr-newsvine" name="shr-newsvine"> <div></div> <label>Newsvine</label> <input type="hidden" value="" name="bookmark[]" /> </li> </ul> Script Sample: $(function() { $("#selector").selectable({ filter: 'li', selected: function(event, ui) { $(".ui-selected").each(obj, function() { $(this).children('input').val($(this).attr('name')); }); }, unselected: function(event, ui) { $(".ui-selected").each(obj, function() { $(this).children('input').val(''); }); } }); });

  • Pushing elements into array as copy

    - by koko
    In prototypejs, why does the following code remove the matching divs from the #test div? What confuses me is that this happens when they are being inserted in the #droparea, and not when they are being pushed in the array. <div id="test"> <div class="foo" id="22.1234"> 1 </div> <div class="foo" id="22.1235"> 2 </div> <div class="foo" id="53.2345"> 3 </div> <div class="foo" id="53.2346"> 4 </div> </div> <div id="droparea"> </div> js var elArray = []; var els = $('test').select('.foo'); els.each(function(x){ if(x.id.split('.')[0] == 22){ elArray.push(x); } }); elArray.each(function(y){ $('droparea').insert({ bottom: y }); });

  • XSLT - Comparing preceding-sibling's elements with current's node element

    - by siondream
    Hello, I have this XML file: <recursos> <recurso url="http://w3c.com"> <descripcion>Consorcio W3C</descripcion> <tipo>externo</tipo> <idioma>ingles</idioma> <contenido>General</contenido> <unidad>Unidad 2</unidad> </recurso> <recurso url="http://html.com"> <descripcion>Especificación HTML</descripcion> <tipo>externo</tipo> <idioma>castellano</idioma> <contenido>HTML</contenido> <version>4.01</version> <unidad>Unidad 3</unidad> </recurso> </recursos> I want to compare one "recurso"'s preceding sibling element "unidad" with the "unidad" of the current "recurso" to check if they're different. I was trying: <xsl:if test="preceding-sibling::recurso[position()=1]::unidad != unidad"> </xsl:if> But I know it's horribly wrong :( I hope you could help me, thank you very much.

  • Custom UITableViewCell trouble with UIAccessibility elements

    - by ojreadmore
    No matter what I try, I can't keep my custom UITableViewCell from acting like it should under the default rules for UIAccessiblity. I don't want this cell to act like an accessibility container (per se), so following this guide I should be able to make all of my subviews accessible, right?! It says to make each element accessible separately and make sure the cell itself is not accessible. - (BOOL)isAccessibilityElement { return NO; } - (NSString *)accessibilityLabel { return nil; } - (NSInteger)accessibilityElementCount { return 0; } - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier //cells use this reusage stuff { if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]) { [self setIsAccessibilityElement:NO]; sub1 = [[UILabel alloc] initWithFrame:CGRectMake(0,0,1,1)]; [sub1 setAccessibilityLanguage:@"es"]; [sub1 setIsAccessibilityElement:YES]; [sub1 setAccessibilityLabel:sub1.text] sub2 = [[UILabel alloc] initWithFrame:CGRectMake(0,0,1,1)]; [sub2 setAccessibilityLanguage:@"es"]; [sub2 setIsAccessibilityElement:YES]; [sub2 setAccessibilityLabel:sub2.text] The voice over system reads the contents of the whole cell all at once, even though I'm trying to stop that behavior. I could say [sub2 setIsAccessibilityElement:NO]; but that would would make this element entirely unreadable. I want to keep it readable, but not have the whole cell be treated like a container (and assumed to be the English language). There does not appear to be a lot of information out there on this, so at the very least I'd like to document it.

  • jQuery - get a list of values of an attribute from elements of a class

    - by Ankur
    I have a class called object which has an element called 'level'. I want to get a list of all the different values of level on the page so I can select the highest one. If I do something like: $(".object").attr("level") will that get me a list of values that are the values of the level attribute? I suspect not, but then how do you do something like that. Note: I don't want to select an HTML object for manipulation as is more common, rather I want to select values of the attribute.

  • PHP Form multiple buttons

    - by Ken
    I have a form with 2 buttons, that depending on which is selected will either be deleted or edited from the database. Those are each individual pages using SQL statements (questionedit and questiondelete). However, when i press a button, nothing happens...Any Ideas Here is my javascript <script type="text/javascript"> function SelectedButton(button) { if(button == 'edit') { document.testedit_questionform.action ="testedit_questionedit.php"; } else if(button == 'delete') { document.testedit_questionform.action ="testedit_questiondelete.php"; } document.forms[].testedit_questionform.submit(); } </script> Here is my form (being echoed from a loop) <form name=\"testedit_questionform\" action=\"SelectedButton\" method=\"POST\"> <span class=\"grid_11 prefix_1\" id=\"\" > Question:<input type=\"text\" name=\"QuestionText\" style=\"width:588px; margin-left:10px;\" value=\"$row[0]\"/> <input type=\"button\" value=\"Edit\" name=\"Operation\"onclick=\"submitForm(\'edit\')\" /> <input type=\"button\" value=\"Delete\" name=\"Operation\"onclick=\"submitForm(\'delete\')\" /> <input type=\"hidden\" name=\"QId\" value=\"$row[3]\" /><br />"); </form>

  • Select multi-select form from array

    - by Budove
    Here's the issue. I have a database column called pymnt_meth_pref, which contains a comma separated string of payment methods chosen from a multiselect form. <td>Payment Methods Used:<br /> <input type="checkbox" name="pyment_meth_pref[]" value="Cash">I can pay with cash.<br /> <input type="checkbox" name="pyment_meth_pref[]" value="Check">I can pay by check.<br /> <input type="checkbox" name="pyment_meth_pref[]" value="Credit Card">I can pay by credit card.<br /> <input type="checkbox" name="pyment_meth_pref[]" value="Paypal">I can pay with Paypal.<br /> </td> This array is posted to a variable and turned into a comma separated string if (isset($_POST['pyment_meth_pref'])) $pymntmethpref = implode(", ", $_POST['pyment_meth_pref']); if (isset($_POST['pyment_meth_acc'])) $pymntmethacc = implode(", ", $_POST['pyment_meth_acc']); This is then inserted into the database as a comma separated string. What I would like to do, is take this string and apply the values to the original form when the user goes back to the form as 'pre-selected' checkboxes, indicated that the user has already selected those values previously, and keeping those values in the database if they choose to edit any other information in the form. I'm assuming this would need to be done with javascript but if there is a way to do it with PHP I'd rather do it that way.

  • sum of square of each elements in the vector using for_each

    - by pierr
    Hi, As the function accepted by for_each take only one parameter (the element of the vector), I have to define a static int sum = 0 somewhere so that It can be accessed after calling the for_each . I think this is awkward. Any better way to do this (still use for_each) ? #include <algorithm> #include <vector> #include <iostream> using namespace std; static int sum = 0; void add_f(int i ) { sum += i * i; } void test_using_for_each() { int arr[] = {1,2,3,4}; vector<int> a (arr ,arr + sizeof(arr)/sizeof(arr[0])); for_each( a.begin(),a.end(), add_f); cout << "sum of the square of the element is " << sum << endl; } In Ruby, We can do it this way: sum = 0 [1,2,3,4].each { |i| sum += i*i} #local variable can be used in the callback function puts sum #=> 30 Would you please show more examples how for_each is typically used in practical programming (not just print out each element)? Is it possible use for_each simulate 'programming pattern' like map and inject in Ruby (or map /fold in Haskell). #map in ruby >> [1,2,3,4].map {|i| i*i} => [1, 4, 9, 16] #inject in ruby [1, 4, 9, 16].inject(0) {|aac ,i| aac +=i} #=> 30 EDIT: Thank you all. I have learned so much from your replies. We have so many ways to do the same single thing in C++ , which makes it a little bit difficult to learn. But it's interesting :)

  • Xcode 4: nib files not loading when run, can't find UI elements

    - by Jordan
    So, I just downloaded Xcode 4 and installed it. I was actually quite looking forward to the single window and integrated IB... - However, when I open and run one of my projects, the nib files that the project uses don't seem to load. Instead I'm left looking at a blank white screen (iPhone). This project ran well and fine on Xcode 3.2. So I thought... this can't be that hard to fix. So I opened up a nib file, thinking that maybe editing or creating a new one from scratch could point me in the right direction. But I can't find the old resources panel from interface builder anywhere. How am I meant to create a new view or add buttons? I know I'm probably just missing something obvious :s Did anyone else have the same nib file problems - is there a fix (or something stupidly simple that I'm forgetting about)? - EDIT: Ok. If I background and un-background the app, the view loads fine. But this happens every time I build, on both iPhone and iOS simulator, i.e. the app doesn't work properly until it's been backgrounded. All the code for loading the view follows from - (void)applicationDidFinishLaunching:(UIApplication *)application. Now I am really confused. - Thanks :)

  • Django Inline Admin elements do not allow editing

    - by nickcartwright
    Hiya, In the Django admin I'd like the ability to edit my models referenced by foreign keys In-Line. I've read all the instructions, added a TabularInline object and my models are displayed there. All looks great, however, I only have the option to add new models and not an option to edit existing. Is there something I've been missing? All the documentation suggests the In-Line models are there to allow you to edit referenced models In-Line, however - all I can see is Add. Any help would be much appreciated!

  • Manipulating original elements with qTip

    - by pjotr
    I have a bunch of divs on my page and each of them has only the class attribute. In the divs there are some spans, which are set up to display a tooltip with the help of qTip. The tooltip should contain three items: Up: anchor, which should move the OuterDiv up (probably something like this: move up/down in jquery) Down: anchor, which should move the OuterDiv down Delete: anchor, which should remove the calling OuterDiv My code so far: <body> <div class="OuterDiv"> <div class="InnerDiv"> <span class="Position">Position 1</span> </div> </div> <div class="OuterDiv"> <div class="InnerDiv"> <span class="Position">Position 2</span> </div> </div> </body> And scripts: $(document).ready(function () { var qTipContent = '<a href="javascript:void(0)" onclick="">&uarr;</a>&nbsp;&nbsp;&nbsp;'; qTipContent = qTipContent + '<a href="javascript:void(0)" onclick="">&darr;</a>&nbsp;&nbsp;&nbsp;'; qTipContent = qTipContent + '<a href="javascript:void(0)" onclick="">X</a>'; $('.Position').each(function () { $(this).qtip({ content: qTipContent, hide: { fixed: true } }) }); }); How should the onclick function in the qTip content look like?

And that's what I'd like to get! Could anybody help me on this?

  • Using Selenium 2's IWebDriver to interact with elements on the page

    - by Andreas Grech
    I'm using Selenium's IWebDriver to write Unit Tests in C#. Such is an example: IWebDriver defaultDriver = new InternetExplorerDriver(); var ddl = driver.FindElements(By.TagName("select")); The last line retrieves the select HTML element wrapped in a IWebElement. I need a way to simulate selection to a specific option in that select list but I can't figure out how to do it. Upon some research, I found examples where people are using the ISelenium DefaultSelenium class to accomplish the following, but I am not making use of this class because I'm doing everything with IWebDriver and INavigation (from defaultDriver.Navigate()). I also noticed that ISelenium DefaultSelenium contains a ton of other methods that aren't available in the concrete implementations of IWebDriver. So is there any way I can use IWebDriver and INavigation in conjunction with ISelenium DefaultSelenium ?
