  • CSS class not having an effect on a div

    - by ETFairfax
    Hi Peeps, The following is an section of my css file plus some HTML. Can anyone tell me when I put class="containerHeader selected" (as is on Test Header A) the background colour is not being set to Red??? Cheers, ET Fairfax. div#builderContainer { margin-top: 15px; width: 390px; height: 700px; border: solid 0px #CCCCCC; background-repeat: no-repeat; } div#builderContainer .container { display: none; -moz-border-radius: 4px; -webkit-border-radius: 4px; border-radius: 4px; /* Corner radius */ border: solid 1px #999999; } div#builderContainer .container div:hover { background-color: #EEEEEE; } div#builderContainer .containerHeader { -moz-border-radius: 4px; -webkit-border-radius: 4px; border-radius: 4px; background: #93c3cd url(images/ui-bg_diagonals-small_50_93c3cd_40x40.png) 50% 50% repeat; border-bottom: solid 0px #999999; margin: 0px; margin-top: 25px; padding: 10px; /* display: none; */ border: solid 1px #999999; font-weight: bold; font-family: Verdana; background-color: #FFF; cursor: pointer; vertical-align: middle; } div#builderContainer .containerHeader:hover { background: #ccd232 url(images/ui-bg_diagonals-small_75_ccd232_40x40.png) 50% 50% repeat; } div#builderContainer .containerHeader:active { background: #db4865 url(images/ui-bg_diagonals-small_40_db4865_40x40.png) 50% 50% repeat; } div#builderContainer .containerHeader .selected { background-color: Red; } <div id="builderContainer"> <div class="containerHeader selected" id="CHA">Test Header A</div> <div class="container" id="CA"></div> <div class="containerHeader" id="CHB">Test Header B</div> <div class="container" id="CB"></div> </div>

  • Problem with XStream Marshalling to return xml and json

    - by MiKu
    When i use new XStream().toXml(someObject); it returns following xml... <response> <status>SUCCESS</status> <isOwnershipVerified class="boolean">false</isOwnershipVerified> </response> and, when i use new XStream(new JsonHierarchicalStreamDriver()).toXml(someObject); it returns following json... {"response": { "status": "SUCCESS", "isOwnershipVerified": { "@class": "boolean""false"} }} Now, since i want to get rid of class attribute altogether (read it not to alias it with anything else, but to remove it) i use following code. XStream xStream = new XStream(); StringWriter writer = new StringWriter(); xStream.marshal(this, new PrettyPrintWriter(writer) { @Override public void addAttribute(final String key, final String value) { if (!key.equals("class")) { super.addAttribute(key, value); } } }); return writer.toString(); which gives follwing xml... <response> <status>SUCCESS</status> <isOwnershipVerified>false</isOwnershipVerified> </response> but, when i pass new JsonHierarchicalStreamDriver() while xStream object creation above, it does NOT return json. it returns the same xml shown above. What is wrong going on here? Thanks in advance...

  • YUI DataTable - Howto have just one paginator?

    - by Rollo Tomazzi
    Hello, I'm using the YUI DataTable in a Grails 1.1 project using the Grails UI plugin 1.0.2 (YUI being 2.6.1). By default, the DataTable displays 2 paginators: one above and another one below the table. Looking up the YUI API documentation, I could see that I can pass an array of YUI containers as a config parameter but - what are the names of these containers? I've tried loooking at the HTML of the page using Firebug. The ID of the divs containing the paginators are: yui-dt0-paginator0 (above) and yui-dt0-paginator1 (below). If I use them to configure the containers for the navigator, then the navigator is just not displayed at all. Here's the relevant extract of the GSP page containing the Datatable element. <div class="body"> <h1>This is the List of Control Accounts</h1> <g:if test="${flash.message}"> <div class="message">${flash.message}</div> </g:if> <div class="yui-skin-sam"> <gui:dataTable controller="controlAccount" action="enhancedListDataTableJSON" columnDefs="[ [key:'id', label:'ID'], [key:'col1', label:'Col 1', sortable: true, resizeable: true], [key:'col2', label:'Col 2', sortable: true, resizeable: true] ]" sortedBy="col1" rowsPerPage="20" paginatorConfig="[ template:'{PreviousPageLink} {PageLinks} {NextPageLink} {CurrentPageReport}', pageReportTemplate:'{totalRecords} total accounts', alwaysVisible:true, containers:'yui-dt0-paginator1' ]" rowExpansion="true" /> </div> </div> Any help? Thanks! Rollo

  • CSS inheritance, aliases and other cool stuff

    - by emzero
    The other day I was randomly browsing the web and I found some program that lets you write CSS aliases and other cool stuff (which I can't remember right now). As an example, I remember you can do something like this: .myclass { background-color: red; greenfont } where greenfont was defined somewhere else as somekind of alias greenfont { color: green; } Then the program will generate the resulting CSS based on the alias and other stuff. Does anyone has used this? Or did I dreamed about it? I cannot find it now :P

  • feedparser fails during script run, but can't reproduce in interactive python console

    - by Rhubarb
    It's failing with this when I run eclipse or when I run my script in iPython: 'ascii' codec can't decode byte 0xe2 in position 32: ordinal not in range(128) I don't know why, but when I simply execute the feedparse.parse(url) statement using the same url, there is no error thrown. This is stumping me big time. The code is as simple as: try: d = feedparser.parse(url) except Exception, e: logging.error('Error while retrieving feed.') logging.error(e) logging.error(formatExceptionInfo(None)) logging.error(formatExceptionInfo1()) Here is the stack trace: d = feedparser.parse(url) File "C:\Python26\lib\site-packages\feedparser.py", line 2623, in parse feedparser.feed(data) File "C:\Python26\lib\site-packages\feedparser.py", line 1441, in feed sgmllib.SGMLParser.feed(self, data) File "C:\Python26\lib\sgmllib.py", line 104, in feed self.goahead(0) File "C:\Python26\lib\sgmllib.py", line 143, in goahead k = self.parse_endtag(i) File "C:\Python26\lib\sgmllib.py", line 320, in parse_endtag self.finish_endtag(tag) File "C:\Python26\lib\sgmllib.py", line 360, in finish_endtag self.unknown_endtag(tag) File "C:\Python26\lib\site-packages\feedparser.py", line 476, in unknown_endtag method() File "C:\Python26\lib\site-packages\feedparser.py", line 1318, in _end_content value = self.popContent('content') File "C:\Python26\lib\site-packages\feedparser.py", line 700, in popContent value = self.pop(tag) File "C:\Python26\lib\site-packages\feedparser.py", line 641, in pop output = _resolveRelativeURIs(output, self.baseuri, self.encoding) File "C:\Python26\lib\site-packages\feedparser.py", line 1594, in _resolveRelativeURIs p.feed(htmlSource) File "C:\Python26\lib\site-packages\feedparser.py", line 1441, in feed sgmllib.SGMLParser.feed(self, data) File "C:\Python26\lib\sgmllib.py", line 104, in feed self.goahead(0) File "C:\Python26\lib\sgmllib.py", line 138, in goahead k = self.parse_starttag(i) File "C:\Python26\lib\sgmllib.py", line 296, in parse_starttag self.finish_starttag(tag, attrs) File "C:\Python26\lib\sgmllib.py", line 338, in finish_starttag self.unknown_starttag(tag, attrs) File "C:\Python26\lib\site-packages\feedparser.py", line 1588, in unknown_starttag attrs = [(key, ((tag, key) in self.relative_uris) and self.resolveURI(value) or value) for key, value in attrs] File "C:\Python26\lib\site-packages\feedparser.py", line 1584, in resolveURI return _urljoin(self.baseuri, uri) File "C:\Python26\lib\site-packages\feedparser.py", line 286, in _urljoin return urlparse.urljoin(base, uri) File "C:\Python26\lib\urlparse.py", line 215, in urljoin params, query, fragment)) File "C:\Python26\lib\urlparse.py", line 184, in urlunparse return urlunsplit((scheme, netloc, url, query, fragment)) File "C:\Python26\lib\urlparse.py", line 192, in urlunsplit url = scheme + ':' + url File "C:\Python26\lib\encodings\cp1252.py", line 15, in decode return codecs.charmap_decode(input,errors,decoding_table)

  • flex chart grid lines dotted

    - by Jonny
    Using the LineChart component of Flex: How do I make the horizontal grid lines (background within the chart) dotted? With the mx:Stroke within the mx:horizontalStroke, I can only set properties like weight, color and alpha. I'd like to make the line dotted... This is what I have now: <mx:LineChart id="linechartDays" width="100%" height="100%" dataProvider="{dayData}" showDataTips="true"> <mx:backgroundElements> <mx:GridLines horizontalChangeCount="1" direction="horizontal"> <mx:horizontalStroke> <mx:Stroke weight="1" color="0xcccccc"/> </mx:horizontalStroke> </mx:GridLines> </mx:backgroundElements> </mx:LineChart>

  • c# winforms - scrollable panel with rectangles

    - by Peanut
    Hi, I'm new to winforms and have tried to track down an answer to the following with no luck ... I have a panel in winforms and add to it a Rectangle that is wider than the panel itself. I've set the panel AutoScroll property to true however the panels horizontal scrollbar never appears. Why is this? And how do I get the scrollbar to scroll? Here is my code to add the rectangle: private void panel1_Paint(object sender, PaintEventArgs e) { Graphics g = e.Graphics; Rectangle rec = new Rectangle(2, 2, 400, 40); g.DrawRectangle(new Pen(Color.Black), rec); g.FillRectangle(new SolidBrush(Color.Blue), rec); } If I add a Label control to the panel and give it a text value that will go beyond the bounds of the panel - then the autoscroll works, but just not for a rectangle. Many thanks.

  • Splashscreen ProgressBar in Eclipse RCP has "dirty" corners

    - by pimpf0r
    Hi there, I am using the RCP Splash Screen along with the built-in ProgressBar (AbsolutePositionProgressMonitorPart). The splash image has a blue background color, but the background of the progressbar seems to be white, which leads to some white corners. There is no "setBackground" on BasicSplashHandler nor does getContent().setBackground(Color) has any noticeable effect. I don't want to be too picky, but since the splash is the first thing you see from the application, I think its very important to be tidy. So, do you have any idea how to get rid of these corners?

  • doofus ASP.Net master page scrollbar question

    - by Stephen Falken
    Like happens to all of us sometimes, I inherited some crappy code I have to fix. We need to center our pages on widescreen machines, so we have a master page layout div like so: .MasterLayout { width:1100px; height: 100%; position:absolute; left:50%; margin-left:-550px; vertical-align:top; } I removed most of the detailed attributes for readability here, but here's how the table for the master page is laid out: <table border="0" cellpadding="0" cellspacing="0" style="width: 100%;"> <tr> <td style="width: 100%" align="center" colspan="2"> </td> </tr> <tr> <td colspan="2" style="height: 20px; background-color: #333;"> <asp:SiteMapPath/> </td> </tr> <tr> <td style="width: 86px; height: 650px; background-color: #B5C7DE; margin: 6px;" valign="top"> <asp:Menu /> <asp:SiteMapDataSource /> </td> <td style="background-color:#ffffff; margin:5px; width:1000px;" valign="top"> <asp:contentplaceholder id="ContentPlaceHolder1" runat="server"/> </td> </tr> </table> When resizing the browser window, the horizontal scrollbar only reaches as far as the left edge of the <asp:contentplaceholder/> control, and the <asp:menu/> that's in the 86px wide <td> is hidden. How can I fix this problem? THANKS IN ADVANCE

  • Regarding Toplink Fetching Policy

    - by Chandu
    Hi, I'm working for a Swing Project and the technologies used are netbeans with Toplink essentials, mysql. The Problem I'm facing is the entity object dosn't get updated after insertions take place while calling a getter collection of the foreign key property. Ex: I have 2 tables Table1,Table2. I have sno column, id column as a primary key in Table1 & is Foreign Key in Table2. Through find method I just get the particular sno object(existed in table 1) set some values persisted to table2 & committed the transaction. When I select the same sno object through find method & gets its collection from Table2 through the getTable2Collection() of the bean(as it is already created in bean by toplink essential) I'm unable to get the latest added record except that all other records of it are displayed. After I close the application & opening it then the new record gets reflected while calling the same sno through the above process. I came to know that this is a kind of lazy fetching and there should be some way of fetch policy to be changed to make the entity object get updated with the changes. So Please help me in this regard. Regards, Chandu

  • Keymap issues with NX from Mac OS X Lion

    - by Andy
    I tried to answer the question from Mark: Keymap issues with NX from Mac OS X Lion to Ubuntu However, it is locked so I figured I would post a new question / answer. I have been trying to answer this for a few days now because I have no issues when connecting through NX Client (technically OpenNX) to FreeNX server from an iMac (with Lion), but if I try to connect with a Macbook Pro I get horrible keyboard binding issues. The fix that is working for me is to go into: ~/.nx/config/HOST.nxs and change: <option key="Current keyboard" value="false"/> <option key="Custom keyboard layout" value="empty"/> <option key="Grab keyboard" value="false"/> I have tried this on three NX Servers and all are fixed. Hope it helps or gets you closer. Always check in the ~/.nx/temp/ for the sshlog and see if --keyboard="empty/empty" instead of "pc105/en" because the Mac is really pc104. 9:05:35: startsession --session="HOST" --type="unix-gnome" --cache="8M" --images="32M" --link="adsl" --geometry="2556\ x1396" --screeninfo="2560x1440x32+render" --keyboard="empty/empty" --backingstore="1" --encryption="1" --composite="1" --\ shmem="1" --shpix="1" --streaming="1" --samba="0" --cups="0" --nodelay="1" --defer="0" --client="macosx" --media="0" --st\ rict="0" --aux="1"

  • 'Invalid column name [ColumnName]' on a nested linq query.

    - by Joe
    I've got the following query: ATable .GroupBy(x=> new {FieldA = x.FieldAID, FieldB = x.FieldBID, FieldC = x.FieldCID}) .Select(x=>new {FieldA = x.Key.FieldA, ..., last_seen = x.OrderByDescending(y=>y.Timestamp).FirstOrDefault().Timestamp}) results in: SqlException: Invalid column name 'FieldAID' x 5 SqlException: Invalid column name 'FieldBID' x 5 SqlException: Invalid column name 'FieldCID' x 1 I've worked out it has to do with the last query to Timestamp because this works: ATable .GroupBy(x=> new {FieldA = x.FieldAID, FieldB = x.FieldBID, FieldC = x.FieldCID}) .Select(x=>new {FieldA = x.Key.FieldA, ..., last_seen = x.OrderByDescending(y=>y.Timestamp).FirstOrDefault()}) The query has been simplified. The purpose is to group by a set of variables and then show the last time this grouping occured in the db. I'm using Linqpad 4 to generate these results so the Timestamp gives me a string whereas FirstOrDefault gives me the whole object which isn't ideal. Update On further testing I've noticed that the number and type of SQLException is related to the class created in the groupby clause. So, ATable .GroupBy(x=> new {FieldA = x.FieldAID}) .Select(x=>new {FieldA = x.Key.FieldA, last_seen = x.OrderByDescending(y=>y.Timestamp).FirstOrDefault()}) results in SqlException: Invalid column name 'FieldAID' x 5

  • Implementing A Static NSOutlineView

    - by spamguy
    I'm having a hard time scraping together enough snippets of knowledge to implement an NSOutlineView with a static, never-changing structure defined in an NSArray. This link has been great, but it's not helping me grasp submenus. I'm thinking they're just nested NSArrays, but I have no clear idea. Let's say we have an NSArray inside an NSArray, defined as NSArray *subarray = [[NSArray alloc] initWithObjects:@"2.1", @"2.2", @"2.3", @"2.4", @"2.5", nil]; NSArray *ovStructure = [[NSArray alloc] initWithObjects:@"1", subarray, @"3", nil]; The text is defined in outlineView:objectValueForTableColumn:byItem:. - (id)outlineView:(NSOutlineView *)ov objectValueForTableColumn:(NSTableColumn *)tableColumn byItem:(id)ovItem { if ([[[tableColumn headerCell] stringValue] compare:@"Key"] == NSOrderedSame) { // Return the key for this item. First, get the parent array or dictionary. // If the parent is nil, then that must be root, so we'll get the root // dictionary. id parentObject = [ov parentForItem:ovItem] ? [ov parentForItem:ovItem] : ovStructure; if ([parentObject isKindOfClass:[NSArray class]]) { // Arrays don't have keys (usually), so we have to use a name // based on the index of the object. NSLog([NSString stringWithFormat:@"%@", ovItem]); //return [NSString stringWithFormat:@"Item %d", [parentObject indexOfObject:ovItem]]; return (NSString *) [ovStructure objectAtIndex:[ovStructure indexOfObject:ovItem]]; } } else { // Return the value for the key. If this is a string, just return that. if ([ovItem isKindOfClass:[NSString class]]) { return ovItem; } else if ([ovItem isKindOfClass:[NSDictionary class]]) { return [NSString stringWithFormat:@"%d items", [ovItem count]]; } else if ([ovItem isKindOfClass:[NSArray class]]) { return [NSString stringWithFormat:@"%d items", [ovItem count]]; } } return nil; } The result is '1', '(' (expandable), and '3'. NSLog shows the array starting with '(', hence the second item. Expanding it causes a crash due to going 'beyond bounds.' I tried using parentForItem: but couldn't figure out what to compare the result to. What am I missing?

I want to use AES Encryption, 'CBC' or 'PKCS5'. var k:String = "1234567890123456"; var kdata:ByteArray = Hex.toArray(k); var txt:String = "hello"; var data:ByteArray = Hex.toArray(Hex.fromString(txt));; var name:String = "simple-aes-cbc"; var pad:IPad =new PKCS5(); var mode:ICipher = Crypto.getCipher(name, kdata, pad); pad.setBlockSize(mode.getBlockSize()); mode.encrypt(data); encrypted.text=Hex.fromArray(data); trace(Hex.fromArray(data)); And here is the code in java String plaintext = "hello"; String key = "1234567890123456"; SecretKey keyspec = new SecretKeySpec(key.getBytes(), "AES"); Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding"); cipher.init(Cipher.ENCRYPT_MODE,keyspec); byte[] encrypted = cipher.doFinal(plaintext.getBytes()); BASE64Encoder base64 = new BASE64Encoder(); String encodedString = base64.encode(encrypted); System.out.println(encodedString); Why the result is not same? Can you guys provide the sample with the same result both of java and flex (encrypt and decrypt)? And if I want to change the paramater, for example, from cbc to ebc, which line that need to be changed? Thanks!

  • Spring transaction : Transaction not active

    - by Videanu Adrian
    i develop a app using struts2, spring 3.1, Jpa2 and Hibernate. From Spring i use transactions and IoC. so, i have an ajax code block that calls for a struts2 action every second (this is happening for every user that is logged into application (simultaneous users are around 20-30 at a time)). this action name is PopupAction public class PopupAction extends VActionBase implements ServletRequestAware { private static final long serialVersionUID = -293004532677112584L; private iIntermedService intermedService; private HttpServletRequest servletRequest; @Override public String execute() { Integer agentId = (Integer) session.get("USER_AGENT_ID"); Intermed iObj; try { iObj = intermedService.getIntermed(agentId,locationsString); } catch (Exception e) { logger.error("Cannot get Intermed!!! "+e.getMessage()); return ERROR; } return SUCCESS; } } and then i have the service class : @Transactional(readOnly=true) public class IntermedServiceImpl extends GenericIService<Intermed, Integer> implements iIntermedService { @Override public Intermed getIntermed (int agentId,String queueIds) throws Exception { Intermed intermedObj = null; //TODO - find a better implementation for this queueIds parameter!!!! try{ String sql = "SELECT i FROM bla bla bla.....)"; Query q = this.em.createQuery(sql); List<Intermed> iList = q.getResultList(); if (iList.size() == 1){ intermedObj = (Intermed) iList.get(0); //get latest object from DB em.refresh(intermedObj); } }catch(Exception e){ e.printStackTrace(); logger.error(e.getCause()+e.getMessage()); throw e; } return intermedObj; } } here is the spring configuration : <bean id="emfI" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="inboundDS" /> <property name="persistenceUnitName" value="I2PU"/> <!-- GlassFish load-time weaving setup --> <property name="loadTimeWeaver"> <bean class="org.springframework.instrument.classloading.glassfish.GlassFishLoadTimeWeaver"/> </property> </bean> <tx:annotation-driven transaction-manager="txManagerI" /> <tx:advice id="txManagerInboundAdvice" transaction-manager="txManagerI"> <tx:attributes> <tx:method name="*" rollback-for="java.lang.Exception"/> </tx:attributes> </tx:advice> I have names for transactionManager because i have 3 datasources and 3 transaction managers. the problem is that my glassfish logs are full of messages like these: -- removed in order to be able to add more recent logs -- So the cause is : Caused by: java.lang.IllegalStateException: Transaction not active. But i have no idea what can cause this. Any help ? thanks Updates So i have added to @Transactional annotation the transaction manager name that he has to use, but this still does not solved my problem. I have captured a log from the time that the transaction is created until i got that exception: 2012-02-08T15:08:55.954+0200|INFO||_ThreadID=184;_ThreadName=Thread-5;|DEBUG [thread-pool-1-80(80)] (AbstractBeanFactory.java:245) -

  • How to control allowed HTML tags in WMD Editor?

    - by Toto
    I am trying to some-how set the valid HTML tags and attributes users would be able to use in WMD Editor in my site. For example, I want to forbid the user to directly set the font size, color, typeface and so on, which is trivial to do with the default settings typing something like: <span style="font-size: 45px; color:#FF0000">Some intrusive text here</span>. I think the way to implement this is through the "wmd_options", but I have not found any documentation or reference regarding this, giving the fact that the 'Options demo' seems to be the only public documentation and it does not show how should I do what I have described above. I've send this same question to [email protected] but didn't get any reply. As stackoverflow uses this editor someone reading this or maybe Jeff knows the answer ;) Thanks in advance!

  • Learning Objective-C: Need advice on populating NSMutableDictionary

    - by Zigrivers
    I am teaching myself Objective-C utilizing a number of resources, one of which is the Stanford iPhone Dev class available via iTunes U (past 2010 class). One of the home work assignments asked that I populate a mutable dictionary with a predefined list of keys and values (URLs). I was able to put the code together, but as I look at it, I keep thinking there is probably a much better way for me to approach what I'm trying to do: Populate a NSMutableDictionary with the predefined keys and values Enumerate through the keys of the dictionary and check each key to see if it starts with "Stanford" If it meets the criteria, log both the key and the value I would really appreciate any feedback on how I might improve on what I've put together. I'm the very definition of a beginner, but I'm really enjoying the challenge of learning Objective-C. void bookmarkDictionary () { NSMutableDictionary* bookmarks = [NSMutableDictionary dictionary]; NSString* one = @"Stanford University", *two = @"Apple", *three = @"CS193P", *four = @"Stanford on iTunes U", *five = @"Stanford Mall"; NSString* urlOne = @"http://www.stanford.edu", *urlTwo = @"http://www.apple.com", *urlThree = @"http://cs193p.stanford.edu", *urlFour = @"http://itunes.stanford.edu", *urlFive = @"http://stanfordshop.com"; NSURL* oneURL = [NSURL URLWithString:urlOne]; NSURL* twoURL = [NSURL URLWithString:urlTwo]; NSURL* threeURL = [NSURL URLWithString:urlThree]; NSURL* fourURL = [NSURL URLWithString:urlFour]; NSURL* fiveURL = [NSURL URLWithString:urlFive]; [bookmarks setObject:oneURL forKey:one]; [bookmarks setObject:twoURL forKey:two]; [bookmarks setObject:threeURL forKey:three]; [bookmarks setObject:fourURL forKey:four]; [bookmarks setObject:fiveURL forKey:five]; NSString* akey; NSString* testString = @"Stanford"; for (akey in bookmarks) { if ([akey hasPrefix:testString]) { NSLog(@"Key: %@ URL: %@", akey, [bookmarks objectForKey:akey]); } } } Thanks for your help!

  • Google Visualization legend format Jquery ui tabs

    - by Liam
    I've got an issue when using the Google Visualization api line chart with Jquery ui tabs. I've got two graphs on two tabs. The first graph, which is visible by default displays fine: the second chart on the hidden tab seems to be messing up the key: I've tried changing the options but nothing I do seems to make any difference. Here are my options: options = { 'title': title, titleTextStyle: { color: color, fontSize: 20 }, 'width': 950, 'height': 400, hAxis: { minorGridlines: { count: x } }, chartArea: { width: 880 }, legend: { position: 'bottom', textStyle: { fontSize: 10 } } }; // Instantiate and draw our chart, passing in some options. var chart = new google.visualization.LineChart(document.getElementById(divId)); chart.draw(data, options); $('#tabs').tabs(); any thoughts on what is causing this and how to prevent it?? Edit If I remove the tabs() call it displays correctly. As per answer below from @Vipul tried setting the div to a fixed width, no difference.

  • Qt 4.6 QLineEdit Style. How do I style the gray highlight border so it's rounded?

    - by krunk
    I'm styling a QLineEdit to have rounded borders for use as a search box. The rounding of the borders themselves were easy, but I can't figure out for the life of me how to round the highlighted portion of the widget when it has focus. I've tried QLineEdit::focus, but this only modifies the interior border. The images below show how the illusion of a rounded qlineedit is lost when it gains focus. QListView, QLineEdit { color: rgb(127, 0, 63); selection-color: white; border: 2px groove gray; border-radius: 10px; padding: 2px 4px; } Images with and without focus:
