• Manually Dispatching a DocumentEvent for testing UI element validation code

  - by Bassam

  Hi. I'm testing a Swing GUI application using the UISpec4J testing framework. I'm testing validation code on a JTextField, but the framework does not support focus-change events, as it runs the application in a headless fashion. The text field has a DocumentEvent attached to it that activates the validation code. I'm trying to figure out how to dispatch the document event manually to activate the validation code. Trying to dispatch focus or mouse events manually haven't been working for me. Thanks for any help!

• Silverlight Bind to TextBlock from RIA Services

  - by DaRKoN_

  I've a TextBlock that looks like so: <TextBlock Text="{Binding Name}" /> This is inside a <Canvas> with the DataContext set to MyClient which is in the ViewModel: public Client MyClient { get; private set; } // This is a RIA Entity, hence supports INotifyPropertyChanged public ViewModel() { MyClient = new Client(); LoadOperation<Client> loadClient = RiaContext.Load<Client>(RiaContext.GetClientsQuery()); loadClient.Completed += new EventHandler(loadClient_Completed); } void loadClient_Completed(object sender, EventArgs e) { MyClient = DB.Clients.Single(); } Setting MyClient like the above does not raise the PropertyChanged event. As such the UI is never updated.

• Check if CSS Class exists in StyleSheet using javascript/jQuery

  - by Akhil Sekharan

  Is there a way to check if there is a class named 'some-class-name' in css? For example, I have: <style type="text/css"> .box { position: absolute; left: 150%; } </style> My intention is to randomly assign a class to a div on certain event: var classList = []; //Need to populate this array $('#updateClass').on('click', function() { $('#resultDiv').attr('class',classList[Math.floor((Math.random()*classList.length)+1)]); }); Is it possible to check by JS/jQuery whether a class named 'box' exists in the stylesheet? Thanks.

• How to break whenever any line of code executes

  - by Aequitarum Custos

  I have a very strange bug, which I believe is caused by some code we have executing, but I'm not sure where. We can reproduce it to the point it happens whenever we click Tab, but short of putting a break point at the beginning of every method in the project to find out what is executing. Is there a way to set visual studio to break whenever anything executes? For those curious about the problem, every now and then, we have a few Rich Text Boxes that refuse to lose focus. You can't click out of it or tab out of it. We have no On Validation or On Text Changed events attached to the control, and believe it's an event attached somewhere else to something we just aren't noticing.

• BlackBerry. How to define direction of Scroll or Focus change?

  - by Lyubomyr Dutko

  Hi, does BlackBerry has any possibility to track focus or scroll change direction? I will describe a case. On UI we have a list and some horizontal tab bar (tab bar at top and below the list actually). If User is somewhere in the middle of a list and decides to click another tab, it appears a little difficult to put focus on the Tab control, so User scrolls to the first list item and after changes focus to tab (as a result very long operation). The point here How to catch event of horizontal scroll to change currently focused tab? And after if you scroll (by trackball) vertically you go back to list. Possibly you can advice with the right approach how to resolve such issues? Thanks Lyubomyr

• JqueryUI Tab Linking from Another Page

  - by pschorr

  I'm having some issues with jqueryui tabs and linking to certain tabs on another page. Basically, each page has tabs, and all are navigational via drop down at the top, with each 'tab' being available in the drop down. Currently I'm able to text-link, but only within the page I'm on, and I'm just lost on the getting it to work correctly from page to page. Here's what I currently got working with internal text link. $(function() { $("#tabs").tabs( {fx: { opacity: 'toggle' }, selected: 0} ); var $tabs = $('#tabs').tabs(); // first tab selected $('a.nutrlink').click(function() { // bind click event to link $tabs.tabs('select', 1); // switch to third tab return false; }); });

• Draw rectangle using Core Graphics with live preview

  - by mikawber

  I'm creating a simple drawing application and would like some help with drawing rectangles based on the user's touch events. I'm able to draw a rectangle using Core Graphics from the point in touchesBegan to the point in touchesEnded. This rectangle is then displayed once the touchesEnded event is fired. However, I would like to be able to do this in a 'live' fashion. Meaning, the rectangle is updated as the user drags their finger. Is this possible? Any help would be greatly appreciated, thank you!

• Prevent content with child nodes from being deleted in umbraco

  - by Soldarnal

  I would like to prevent content nodes from being trashed if they have any children. I setup an event handler like so: public class KeepSafeEvents : ApplicationBase { public KeepSafeEvents() { Document.BeforeMoveToTrash += new Document.MoveToTrashEventHandler(Document_BeforeMoveToTrash); } void Document_BeforeMoveToTrash(Document sender, umbraco.cms.businesslogic.MoveToTrashEventArgs e) { if (sender.HasChildren) { e.Cancel = true; } } } However, this doesn't seem to work. I assume it is because the delete process moves the child nodes to trash first before dealing with the parent node (which then has no children). Is there another possible solution? Or am I making a simple mistake above?

• jquery draggable accept: classpath

  - by heldopslippers

  Hi guys.. I have problems with the following bit of javascript/jquery code: this.droppable = function(){ $('.imageWindow .body .item').draggable(); $('.groupWindow .body .item').droppable({ accept: $(".imageWindow .body .item"), over: function(event, ui) { alert("this is valid!"); }, drop: function(){ alert('dropped'); } }); } As you maybe know it is not possible to pass the following in the accept option: $(".imageWindow .body .item") But what is possible ? I want to pass a "class path" as an accept option ! It is probably a simple answer but i can't figure it out. Of course i could do: accept: ".item" But because "groupWindow .body .item" is a sortable it would also accept himself! Thanxs if you can help me!

• Z-Index problems with IE6 and html <select> element

  - by rsturim

  I have a <div> that opens up on a jquery hover event (display goes from hidden to block). Sometime it's opens up over some form elements. And of course it works fine in all browsers except IE6. <select> boxes bleed through as if there z-index is higher than the <div> tag. I've tried setting the <div> tag with a higher z-index, but it still gets ignored by IE6. I'm hoping to implement any fix -- jquery or css, I really don't care at this point. Any ideas?

• Alternatives to UIWebView for rich content?

  - by ojreadmore

  In my app, I am displaying 4 "tabs", each are local content through a UIWebView. I create HTML markup from my simple data. This is slow to load and I'm trying to speed it up. I'm using UIWebView to accomplish these: 1. hyperlinks 2. some styling - font colors 3. HTML tables Writing my own class to handle this is okay for (1.) hyperlinks - I can use a touch event to call a method. And (2.) styling - I can use UILables to do basic formatting, no biggie here. BUT what I really love about the UIWebViews is the (3.) HTML tables! I find it troublesome to line up the UILabels in a way that mimics HTML Tables, for instance, one cell's height in a row changes the height of all cells. I'm looking for another perspective or knowledge of an alternative.

• 2 or more Controls only 1 is considered Active

  - by Don

  I have 2 controls (MyCtrl) next to each other called ctrlLeft and ctrlRight. Whenever one receives interaction it is considered active (by default the left one). I override OnDraw and customize the look of the active one a bit. Currently I have a property Active and an event that I subscribe to from all MyCtrl in there I store a reference to the active one like this: if (sender is MyCtrl) { ctrlActive = (sender as MyCtrl); ctrlLeft.Active = !(ctrlRight.Active = (ctrlActive == ctrlRight)); } Either way I need to have ctrlActive as I use it for other things but what I am wondering is if this is the best way make them aware of each other? Another option I thought of was to store references to every possible MyCtrl and then loop through em all and activate / deactivate the one that match sender just in case I in the future add a ctrlMiddle. Are my thoughts wrong, is there better options to do this. For example, how does radiobuttons accomplish their similar functionality?

• How to Implement Dynamic Timestamp in Web Page?

  - by Morgan Cheng

  In Facebook and twitter, we can see that there is a timestamp like "23 seconds ago" or "1 hour ago" for each event & tweet. If we leave the page for some time, the timestamp changes accordingly. Since it is possible that user machine doesn't have same system time as server machine, how to make the dynamic timestamp accurate? My idea is: It is always based on server time. When request is sent to server for the web page, timestamp T1 (seconds to 1970/1/1) is rendered into inline javascript variable. The displayed timestamp ("23 seconds ago") is calculated by T1 instead of local time. I'm not sure whether this is how Facebook/Twitter do it. Is there any better idea?

• discrepancy in using AsyncTask, code is executed in weird order

  - by Pentium10

  Hello, In onCreate method I hav the following order of code objItem = new DbClass(this);//the onCreate event creates the database new PrepareAdapter1().execute();//this task uses the tables, but SQLException occures, tables doesn't exists As you see in my short code, I get a new instance of the SQLiteOpenHelper class, which does create the tables in onCreate. And after that I start an AsyncTask instance where I use the created table. But I get SQLiteException as table doesn't not exists. I am using this code in wrong way? I expect the table to be created when I launch the thread.

• How can I implement lazy loading on a page with 500+ images?

  - by Fedor

  I basically have a booking engine unit results page which must show 40 units and per each unit there's 1 large image of the first thumbnail and an X number of accompanying thumbnail images. I've been using the jquery lazy load plugin, but it's not thorough enough ( I'm invoking it on DOM Ready ), plus it doesn't really work in IE ( 50% of the clients use IE so it's a big issue ). What I think I really need to do is not really spit out the image but a fake element such as a span, and possibly modify my code such that if the user views the span, render it into an image element. <span src="/images/foo.gif"> The booking engine relies on JS so I think I might be forced to just rely on ajaxifying all the thumbnails and have event handlers on window scroll, etc in order for the page to be "usable" and load at an average time ( 2-3 seconds instead of 5-30s on high speed DSL/Cable ). I'd appreciate any examples or ideas.

• jQuery UI: moving items from one list to another

  - by AnC

  While this should be relatively straightforward, I can't figure out how to move (rather than copy) LI elements between ULs. All I want is to drag any item from list foo to list bar (or vice versa) without duplicating the element. While connectToSortable does almost exactly what I want (though I'd prefer to avoid sortable), it clones the element - and manually removing the original element by reacting to the stop event turns out to be not so easy (e.g. ensuring that a valid drop actually happened). A simple "hello world" example would help me greatly.

• C#: Creating an editable object inside a PictureBox

  My goal is to let the user click on a specific location on a map to add a Placemark, and then edit the placemark by click its icon (change its name, move it around, etc). I am using a PictureBox to show the map, and by registering the MouseDoubleClick event I am drawing an Image on the map with GDI+ DrawImage() method. The problem is that after the placemark's Image was drawn, it does not editable: the user cant click the icon and move it around, change its name etc. Is there any other design pattern I can follow? maybe using other controls... ?

• How to slow down Uploadify plugin script voor jQuery

  - by Peter

  Now if that isn't a weird question, I don't know what is. But here is the problem: I have a function in my "onSelect" option that has to collect some data (through AJAX) and I have a function in my "onComplete" option that processes the just uploaded files based on the data "onSelect" collected. However, with very small files, the "onSelect" hasn't finished yet before the upload is complete and the "onComplete" fails because it lacks the necessary data. Bigger files work just fine. So, I'm looking for a way to stall the upload of the file. To let it start only after the function in onSelect completed fetching the necessary data. Any ideas? Here is an example of the function that the onSelect triggers: var foo = new Array(); function checkDB( event, queueID , fileObj ) { $.post( ajax_folder + 'fetchData' , { ref: "someValue" } , function( data ){ foo[ queueID ] = data.result; } , 'json' ); return true; }
