  • css layout for footer at bottom with dynamic ajax content changing height of page

    - by m42
    [Update] I actually compromised on this problem for now by foregoing the fixed footer design. It seems that there is no problem with dynamic content moving the footer and resizing containers appropriately unless the footer is fixed to the browser bottom initially. I hope others will eventually provide a great solution that encompasses the best of both worlds. I spent all day trying to get the footer to move down the page to accommodate dynamically added (via ajax) content. I really need some pointers or links because I haven't found anything that helps. Basically: My site has some pages that begin with only a text box and a button so that the total height of the content area is only a few inches beneath the header area. I don't have any problem getting the sticky footer working so that the footer appears at the bottom of the browser window even when there is very little content on screen. That same css layout works fine for other pages that have content that extends beneath the browser window. The catch: The content has to be rendered and passed to the browser with the initial load. The Problem: Any content that is added to the page via AJAX after the initial load paints down the page correctly -- but the footer remains in its initial location. Please tell me there is a fix for this. I can't post the css until checking with my boss first - if possible - and if needed, I will later - but it's just a very basic version of the many sticky footer css solutions floating around the web. Thanks.

  • FileReference.browse() stops playback on some Flash Players

    - by Christophe Herreman
    We have an issue were the server session associated with a Flex client times out when the browse file dialog is open for a time longer then the configured session timeout. It seems that on some players, the playback is stopped when browse or download on a FileReference is executing. This also causes remote calls to be blocked and hence our manual keep-alive messages are not sent to the server, resulting in a session timeout. I searched for some info on this in the docs and found a notice of it, but it does not explicitly list the players it does (not) work. Would anyone know were I could find a complete list? PS: here are the links that mention this behavior: http://livedocs.adobe.com/flex/3/html/help.html?content=17_Networking_and_communications_7.html While calls to the FileReference.browse(), FileReferenceList.browse(), or FileReference.download() method are executing, most players will continue SWF file playback. http://livedocs.adobe.com/flex/3/langref/flash/net/FileReference.html While calls to the FileReference.browse(), FileReferenceList.browse(), or FileReference.download() methods are executing, SWF file playback pauses in stand-alone and external versions of Flash Player and in AIR for Linux and Mac OS X 10.1 and earlier Anyone knows what is meant with an "external Flash Player"? PPS: we tested this on Linux (10.0.x and 10.1.x) in Firefox where it seems to stop playback and on Windows (10.0.x) in IE where playback seems to continue.

  • Recommendations for jQuery tooltips

    - by jerome
    I am looking for tooltip plugins for jQuery that would allow for the following type of behavior. <a href="somewhere.html"> <span> <img src="someimage.jpg" style="display: none;" /> Here is the tooltip content. </span> Here is the link to somewhere. </a> The behavior that I am hoping for is to hover over "Here is the link to somewhere" and have a tooltip pop up showing the content of the span containing "someimage.jpg" and "Here is the tooltip content". I would prefer that the tooltip track along with the mouse's movement over the link and that the tooltip's appearace (background color, opacity, border color, etc.) be configurable. The two most popular tooltips that I have found, "clueTip" and Jörn Zaefferer's "Tooltip" do not seem to fit the bill, unless I am missing something. Ultimately, the links and images will be dynamically generated.

  • How to enter text into the "Write something..." box on Facebook and click Submit

    - by Peter Payne
    Hello, I am trying to manipulate Facebook pages in various ways, using Javascript browser elements. I'd need to be able to insert some text into the top "Type something..." box that shows on my site's fan page (or alternately, "click into" the field and I can type the text using GUI scripting), then click the "submit" button as if i'd done it by hand. It's tricky since the page is very Ajax heavy and I can't find the names of the elements I need to manipulate, let alone how to manipulate them as they're not using traditional form fields I'm used to. Can anyone help me figure out how to do this with javascript commands, which I'd be calling from Applescript on the Mac? Many thanks in advance. UPDATE Thanks for the comments below. Believe me, I am not trying to do anything spammy or douchy, mainly posting links to products that have gone live on page facebook page, but do it during the business day when people are on rather than at strange hours of the day. I am located in Japan so my sleep period is right when people are using FB. The solution I came up with for clicking the button was got using UI Browser, an outstanding tool if you're trying to script on the Mac. The script that clicked the button for me was: tell application "Safari" activate set thename to name of (get current tab of window 1) delay 3 tell application "System Events" tell process "Safari" try click button "Share" of group 1 of group 2 of list 3 of group 9 of UI element 1 of scroll area 1 of group 3 of window thename -- this one works on the mini? on error click button "Share" of group 1 of group 2 of list 3 of group 9 of UI element 1 of scroll area 1 of group 2 of window thename -- did not work end try end tell end tell end tell Hope this is useful to anyone.

  • jQuery AJAX chained calls + Celery in Django

    - by user1029968
    Currently clicking one of the links in my application, triggers AJAX call (GET) that - if succeeds - triggers the second one and this second one - if succeeds - calls the third one. This way user can be informed which part of process started when clicking the link is currently ongoing. So in the template file in Django project, click callback body for link mentioned looks like below: $("#the-link").click(function(item)) { // CALL 1 $.ajax({ url: {% url ajax_call_1 %}, data: { // something } }) .done(function(call1Result) { // CALL 2 $.ajax({ url: {% url ajax_call_1 %}, data: { // call1Result passed here to CALL 2 } }) .done(function(call2Result) { // CALL 3 $.ajax({ url: {%url ajax_call_3 %}, data: { // call2Result passed here to CALL 3 } }) .done(function(call3Result) { // expected result if everything went fine console.log("wow, it worked!"); console.log(call3Result); }) .fail(function(errorObject) { console.log("call3 failed"); console.log(errorObject); } }) .fail(function(errorObject)) { console.log("call2 failed"); console.log(errorObject); } }) .fail(function(errorObject) { console.log("call1 failed"); console.log(errorObject); }); }); This works fine for me. The thing is, I'd like to prevent interrupting the following calls if the user closes the browser and the calls are not finished (as it will take some time to finish all three), as there is some additional logic in Django view functions called in each GET request. For example, if user clicks the link and closes the browser during CALL 1, is it possible to somehow go on with the following CALL 2 and CALL 3? I know that normally I'd be able to use Celery Task to process the function but is it still possible here with the chained calls mentioned? Any help is much appreciated!

  • Updating target workbook - extracting data from source workbook

    - by Allan
    My question is as follows: I have given a workbook to multiple people. They have this workbook in a folder of their choice. The workbook name is the same for all people, but folder locations vary. Let's assume the common file name is MyData-1.xls. Now I have updated the workbook and want to give it to these people. However when they receive the new one (let's call it MyData-2.xls) I want specific parts of their data pulled from their file (MyData-1) and automatically put into the new one provided (MyData-2). The columns and cells to be copied/imported are identical for both workbooks. Let's assume I want to import cell data (values only) from MyData-1.xls, Sheet 1, cells B8 through C25 ... to ... the same location in the MyData-2.xls workbook. How can I specify in code (possibly attached to a macro driven import data now button) that I want this data brought into this new workbook. I have tried it at my own location by opening the two workbooks and using the copy/paste-special with links process. It works really well, but It seems to create a hard link between the two physical workbooks. I changed the name of the source workbook and it still worked. This makes me believe that there is a "hard link" between the tow and that this will not allow me to give the target (MyData-2.xls) workbook to others and have it find their source workbook.

  • Generating URLs when not using an integer as an id?

    - by Synthesezia
    So I'm building a blog engine which has /articles/then-the-article-permalink as it's URL structure. I need to have prev and next links which will jump to the next article by pub_date, my code looks like this: In my articles#show @article = Article.find_by_permalink(params[:id]) @prev_article = Article.find(:first, :conditions => [ "pub_date < ?", @article.pub_date]) @next_picture = Article.find(:first, :conditions => [ "pub_date > ?", @article.pub_date]) And in my show.html.erb <%= link_to "Next", article_path(@next_article) %> <%= link_to 'Prev', article_path(@prev_article) %> In my articles model I have this: def to_param self.permalink end The specific error message I get is: article_url failed to generate from {:action=>"show", :controller=>"articles", :id=>nil}, expected: {:action=>"show", :controller=>"articles"}, diff: {:id=>nil} Without the prev and next everything is working fine but I'm out of ideas as to why this isn't working. Anyone want to helo?

  • redirecting the root domain - SEO and other issues, need some guidance!

    - by Jim Sp
    I'm not familiar with some of these forwarding methods and I need help. My issue is this: I have a site hosted on discountasp.net. My domain was registered through 1&1 and I redirected the DNS to what discountasp.net wanted. So when a user types www.mydomain.com, he/she sees the ASP.NET site hosted on discountasp.net, which is all fine My main page is Index.aspx, I really suck at html page design and I don't have time or the talent to fiddle with it (or money to get it done by a pro). The rest of the pages are fine. I want to use a good theme from tumblr or bloggr - one of the blog sites and create a page that I want to use as the first page - directly on blogger or tumblr - say yyy.blogspot.com (I have many reasons, so for now please don't bash my decision - let's just say that's what I want). That means when a user types www.mydomain.com, it should redirect it to the blogger or tumblr page. Everything else stays the sme - the links on the blogger page will say www.mydomain.com/xxxx and show up what's on the hosted website. I have setup the IIS rewrite rules etc. etc. so that all works just fine The bottom line is I want to show an external site's web page as my root page. I suppose I'm struggling to even explain what I want! I can of course do a response.redirect on the Index.aspx page - which is the simplest way to manage this, but the big question is will this hurt SEO in some way? If not, that would be what I do and leave the rest of the infrastructure intact (I have already done this to test and it works fine) Thank you very much j

  • CanCan polymorphic resource access problem

    - by Call 'naive' True
    Hi everybody, i don't quite understand how to restrict access to links in this particular case with CanCan. I always get "Edit" link displayed. So i believe the problem is in my incorrect definition of cancan methods(load_ and authorize_). I have CommentsController like that: class CommentsController < ApplicationController before_filter :authenticate_user! load_resource :instance_name => :commentable authorize_resource :article def index @commentable = find_commentable #loading our generic object end ...... private def find_commentable params.each { |name, value| if name =~ /(.+)_id$/ return $1.classify.constantize.includes(:comments => :karma).find(value) end } end end and i have in comments/index.html.erb following code that render file from other controller: <%= render :file => "#{get_commentable_partial_name(@commentable)}/show.html.erb", :collection => @commentable %> you can think about "#{get_commentable_partial_name(@commentable)}" like just "articles" in this case. Content of "articles/show.html.erb": <% if can? :update, @commentable %> <%= link_to 'Edit', edit_article_path(@commentable) %> | <% end %> my ability.rb: class Ability include CanCan::Ability def initialize(user) user ||= User.new # guest user if user.role? :admin can :manage, :all elsif user.role? :author can :read, [Article, Comment, Profile] can :update, Article, :user_id => user.id end end end relations with models is: class Comment < ActiveRecord::Base belongs_to :commentable, :polymorphic => true, :dependent => :destroy ... end class Article < ActiveRecord::Base has_many :comments, :as => :commentable, :dependent => :destroy ... end i have tried debug this issue like that user = User.first article = Article.first ability = Ability.new(user) ability.can?(:update, article) and i always get "= true" in ability check Note: user.role == author and article.user_id != user.id if you need more information please write thank's for your time && sorry for my english

  • Jetty 7 will not allow me to customize a session cookie path

    - by Bob Obringer
    Using Jetty 7.0.2, I am unable to set a custom session cookie path. I am hosting multiple sites on the same server using apache to proxy requests to the proper context. (replaced http as htp as stackoverflow thinks my multiple links might be spam) <VirtualHost *:80> ServerName context.domain.com ProxyRequests On ProxyPreserveHost Off <Proxy *:80> Order deny,allow Allow from 127.0.0.1 </Proxy> ProxyPass / htp://localhost:8080/context/ ProxyPassReverse / htp://localhost:8080/context/ <Location /> Order allow,deny Allow from all </Location> </VirtualHost> Jetty is running on the same server on port 8080 and my context is available @ /context The user accesses the application @ htp://context.domain.com but jetty is setting the path for the session cookie @ /context. This prevents the browser from accessing the cookie since the the actual path to the context is not being used. I need to override Jetty's default setting to set the cookie for the context, and set the path at the root ( / ). In my Jetty's webdefault.xml I have the following, which is partially working: <context-param> <param-name>org.eclipse.jetty.servlet.SessionCookie</param-name> <param-value>CustomCookieName</param-value> </context-param> <context-param> <param-name>org.eclipse.jetty.servlet.SessionPath</param-name> <param-value>/</param-value> </context-param> The cookie is properly set with a custom name, but it is NOT setting the SessionPath. No matter what I set the value to... it refuses to set a cookie at any path but /context. This has been driving me crazy so any help would be greatly appreciated.

  • .htaccess redirect or rewrite to default language url

    - by Saif Bechan
    I have a website that is currently in Dutch. Now I want to make the website multi-language starting with English. I am not that good at .htaccess files and the information on the web is quite confusing. The website I have now uses pretty urls, so all my urls look like this: http://mydomain.com/about/info http://mydomain.com/about/contact The code that I use for that is the following: <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-l RewriteRule ^(.*)$ index.php?rt=$1 [L,QSA] </IfModule> I really do not know what this means, esp the [L,QSA]. But it's ok, it works for now. But now I want to add a default redirect to the code. So it becomes as follow http://mydomain.com becomes http://mydomain.com/nl I assume all my old links http://mydomain.com/about/info will not work anymore, but that is a step I am willing to take. Can someone please help me with this code. I have seen a lot of peaces of code, but I can not find the right one.

  • Javascript/jQuery: programmatically follow a link

    - by Dan
    In Javascript code, I would like to programmatically cause the browser to follow a link that's on my page. Simple case: <a id="foo" href="mailto:[email protected]">something</a> function goToBar() { $('#foo').trigger('follow'); } This is hypothetical as it doesn't actually work. And no, triggering click doesn't do it. I am aware of window.location and window.open but these differ from native link-following in some ways that matter to me: a) in the presence of a <base /> element, and b) in the case of mailto URLs. The latter in particular is significant. In Firefox at least, calling window.location.href = "mailto:[email protected]" causes the window's unload handlers to fire, whereas simply clicking a mailto link does not, as far as I can tell. I'm looking for a way to trigger the browser's default handling of links, from Javascript code. Does such a mechanism exist? Toolkit-specific answers also welcome (especially for Gecko).

  • VirtualBox limits size of .js file, that can be included from guest additions folder?

    - by c69
    This question might belong to SuperUser, but i'll try to ask it here anyway, because i believe, some web developers might encountered this weird behavior. When testing a site for IE8/winXP compatibility on VirtualBox i run into weird issue of $ is undefined, which is caused by jQuery (and jQuery UI) being not included, when referenced by relative path, which resolves to file:/// url. Seemingly because their size was too big (above 200KB). Simply replacing links to those 2 big files to http:// ones solved the issue for me. But here is the question: why did this happen ? is it a misconfiguration ? a bug ? a known design decision ? Details: VirtualBox 4.1.8 host os: win7 64bit, guest os: xp sp3 32 bit guest additions installed, page was launched from VB shared folder the bug was manifesting itself in all browsers (even in opera, which ignores ie security settings, afaik) ie configuration is default script was included like this: <script type="text/javascript" src="js/libs/jquery/jquery-1.7.2.js"> exact size limit was not deducted.

  • CSS Experts required - problems with Z-Index stack in my page design

    - by Jack W-H
    Howdy y'all! Basically I'm having some problems with Z-Index. Although I'm not amazing at CSS I would reckon I was reasonably good, but really can't work this out. You'll see at the URL... http://howcode.com/code/ ... that my problem is that links in the returned 'Popular' results aren't clickable or anything. I've concluded this is due to their Z-Index being messed up. I had to fiddle and tweak with Z-Index to get the tabs - Popular, Top Rated, Featured etc. - to show above the codebg div. When I adjusted the Z-Index so that the results were definitely on top, they acted as normal - text could be selected, the ratings images hovered, etc. etc. However the downside to this was that my Popular, Top Rated, Featured tabs were all placed BENEATH the background image for the returned results. If anyone can post a workaround or alteration to my CSS that would be much appreciated. Please don't forget this is a test site and design and any other URLs are likely not to work, I haven't uploaded any database configs yet or whatever! Attached are a couple of screenshots to clarify what I mean: This is what I WANT to happen (not that in actual fact in this screenshots link aren't clickable, just to demo my point though): This is what DOES happen when I adjust the Z-Index properties (I don't want this!): Thanks y'all!

  • Really Need a Facebook App to post to Facebook Page Wall?

    - by Lee Englestone
    Hi, I'm using the Facebook API Graph (C# & ASP.NET) to try to dynamically post to a Facebook page I created. Looking at the code samples floating around.. they suggest creating a Facebook App first (which I have done).. However.. I have 3 different pages I want to post to.. Do I need to create an app for each? (I want to post different things to the 3 pages, not the same posts to each) I just want messages & links to appear as Wall posts. I'm not bothered about having an 'app' that has 'canvas' that is placed in an IFrame. Question : So do I still need to write one or more Facebook Apps to post to my 3 different Facebook pages?? Where I am so far.. I can pass in my apps credentials and get back the access_token. But my posts don't appear to be going anywhere. I'd rather drop the 'facebook application /canvas' approach if possible If I can post directly to a wall (For the above reasons). Oh, and before you ask. I don't want to post to my Apps Wall page, I want to post to my other pages (Unless I have to post to my Apps Wall page first?). I'm sure loads of people have the same questions.. Thanks in advance. -- Lee

  • GPL/LGPL-licensed images + iPhone development

    - by cubic1271
    Since the majority of legal links / READMEs I've found when browsing icon sets refer me to the general GPL / LGPL (as opposed to a specialized version of some kind) when I'm looking at license restrictions, I'm having a terrible time trying to figure out what would constitute source code, linking, etc. when it comes to images and / or icons. One specific example: under section 5 of the GPL, modifications must carry notices in the source code. . . how do I do that with an image? I guess I could try to find a few unused bits and encode my modifications in there (steganography, anyone?), but somehow that doesn't seem like what the license is shooting for. There are also other sections in there where I have no idea how to begin to comply with. Thus, I'm really confused. What exactly are the implications of using GPL and / or LGPL licensed images in something that isn't itself GPL'd? Specifically, I'd like to know what using GPL icons in an iPhone application might mean from a legal point of view. It feels like I'm missing something obvious here; any enlightenment / references would be appreciated!

  • How to authenticate multiple entry points in a facebook app?

    - by Simon_Weaver
    I am using an IFrame application with XFBML and the new Javascript API. I'd like to have a facebook application with multiple entry points. These will most likely represent different links coming from a fan page tab. I can do this quite easily if the pages don't require authentication - for instance I can create several pages under the app and if a new user comes I can send them to any page: http://apps.facebook.com/myapp/offers http://apps.facebook.com/myapp/game http://apps.facebook.com/myapp/products The problem is that if I need to have authentication then once the user is authenticated they get redirected to my default post-authorization url. Is there a way for a user that comes to /game to stay on /game after they are authenticated without redirecting. I thought I could do it with the AJAX login form - but I cannot find out how to do that in a Facebook IFrame application. I think the example using requirelogin only works for FBML. <a href="http://apps.facebook.com/mysmiley" requirelogin=1> Welcome to my app</a>. Is there a way to accomplish this with Facebook APIs - or will I have to do some kind of clever cookie handling?

  • ASP.net MVC Linq-To-SQL Many-To-Many Field Binding

    - by user336858
    Hi there, The short version of this question is "Is there a way to gracefully handle database insertion for an object that has a many-to-many field that has been set up in a partial class?" Apologies if it's been asked before. Example Suppose I have a typical MVC setup with the tables: Posts {PostID, ...} Categories {CategoryID, ...} A post can have more than one category, and a category can identify more than one post. Thus suppose further that I need an extra table: PostCategories {PostID, CategoryID, ...} This handles the many-to-many relationship between posts and categories. As far as I know, there's no way to do this in Linq-to-SQL right now so I have to shoehorn it in by adding a partial Post class to the project to add that functionality. Something like: public partial class Post { public IEnumerable<Category> Categories{ get { ... } set { ... } } } So I can now create a "Create" view that automatically populates a "Categories" UI item. This is where the trouble starts. So here's my question: How do you get automatic object model binding to work cleanly with an object that has a many-to-many relationship to control? The workaround that makes many-to-many relationships possible relies on the Post object having a PostID in order to be associated with CategoryID(s), which is only issued after the Post object has been submitted for validation and insertion. Bit of a Catch22 here. Any terminology, links, or tips you can provide would be tremendously helpful!

  • jQuery or CSS - How do you make a link in a table row appear underlined even when the cursor is in a

    - by adam
    I have a table of 3-4 columns, the central one being task names that are also links(yet another todo app..groan). Im trying to make it so that whenever the mouse hovers over any part of the table row - not just the link itself - the link will appear underlined. Its a small detail but its been annoying me like hell and i refuse to let it get the better of me now. At first i tried jQuery with a (forgive the obvious syntax errors but this is the jist) $('#row_in_question').hover( function(){ $(this).find(...the link..).toggleClass("highlighted") }, function(){ $(this).find(...the link..).toggleClass("highlighted") } ); with this as a styling for the a element in general .highlighted { text-decoration: underlined; } and it did indeed toggle the highlighted class on that link - however css inheritance got in the way and no visual changes made. Since i previously styled that link to have no underline when not hovered it wouldnt change the style. So how do i go about this? I dont want the whole row to become clickable, I just want the text to become underlined.

  • IE6 transparency+radio button can't be clicked

    - by Jonas Byström
    IE6: when I place a partially transparent image in a div, the radio buttons in that div that overlap the non-transparent pixels of the image become unclickable. Example: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <style media="screen" type="text/css"> div { position: relative; width: 500px; height: 300px; _filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src=http://upload.wikimedia.org/wikipedia/commons/thumb/f/fc/Olympic_flag_transparent.svg/200px-Olympic_flag_transparent.svg.png, sizingMethod='crop'); } input { position: absolute; top: 40px; left: 60px; } </style> </head> <body> <div> <input type="radio" value="1" name="1"/> </div> </body> </html> If you test the code, you can also try moving the button from (60, 40) to (40, 40) where the image is transparent, and voilà - the clicking is back in business again. This bug might, or might not, be related to the IE6 links transparency bug, but I'm not knowledgable enough to grasp any resemblence. Have I done something wrong? Or how can I circumvent? Is there some other option apart from removing the _filter:progid?

  • PyGTK: Trouble with size of ScrolledWindow

    - by canavanin
    Hi everyone! I am using PyGTK and the gtk.Assistant. On one page I have placed a treeview (one column, just strings) in a gtk.ScrolledWindow (I wanted the vertical scrollbar, since the list contains about 35 items). Everything is working fine; the only thing that bugs me is that I have not been able to figure out from the documentation how to set the size of the scrolled window. Currently only three items are displayed at a time; I would like to set this number to 10 or so. Below is the code. As you can see I have tried using a gtk.Adjustment to influence the scrolled window's size, but as - once more - I have been incompetent at retrieving the required info from the documentation, I don't actually know what values should be put into there. self.page7 = gtk.VBox() # The gtk.Adjustment: page_size = gtk.Adjustment(lower=10, page_size=100) # just used some arbitrary numbers here >_< scrolled_win = gtk.ScrolledWindow(page_size) scrolled_win.set_policy(gtk.POLICY_AUTOMATIC, gtk.POLICY_AUTOMATIC) # only display scroll bars when required self.character_traits_treeview = gtk.TreeView() self.character_traits_treestore = gtk.TreeStore(str) self.character_traits_treeview.set_model(self.character_traits_treestore) tc = gtk.TreeViewColumn("Character traits") self.character_traits_treeview.append_column(tc) cr = gtk.CellRendererText() tc.pack_start(cr, True) tc.add_attribute(cr, "text", 0) self.character_trait_selection = self.character_traits_treeview.get_selection() self.character_trait_selection.connect('changed', self.check_number_of_character_trait_selections) self.character_trait_selection.set_mode(gtk.SELECTION_MULTIPLE) self.make_character_traits_treestore() # adding the treeview to the scrolled window: scrolled_win.add(self.character_traits_treeview) self.page7.pack_start(scrolled_win, False, False, 0) self.assistant.append_page(self.page7) self.assistant.set_page_title(self.page7, "Step 7: Select 2-3 character traits") self.assistant.set_page_type(self.page7, gtk.ASSISTANT_PAGE_CONTENT) self.assistant.set_page_complete(self.page7, False) def check_number_of_character_trait_selections(self, blah): # ... def make_character_traits_treestore(self): # ... I know I should RTFM, but as I can't make head or tail of it, and as further searching, too, has been to no avail, I'm just hoping that someone on here can give me a hint. Thanks a lot in advance! PS: Here are the links to: the gtk.ScrolledWindow documentation the gtk.Adjustment documentation

  • jQuery: one-liner for removing all children but one

    - by user1352530
    HTML code is: <li> <a href="#" /> <ul> <li> <a href="#"/> </li> </ul> </li> I want to delete any node under $(this) = li that is not a link. If there are more than one link, just the first one is saved, and if there are links inside the ul tag, they are not included because they are descendants and no childrens. Something like this (I am cloning and outputting html): $(this).clone().remove('not(a:first)').html(); //Assuming remove looks for "a" as a first child Does not work, so I try with this: $(this).clone().children().remove('not(a:first)').parent().html(); Does not work so I try with this: $(this).clone().remove('not(>a:first)').html(); I need the original element as a reference after removal for chaining more operations EDIT: Ok! Second one works with a little syntax correction as some appointed (:not( instead of not() but I would like to know if there is any other solution similar to the third line so I don't have to do children().remove().parent(). Thank you!

  • EF 4.0 Code only assocation from abstract to derived

    - by Jeroen
    Using EF 4.0 Code only i want to make an assocation between an abstract and normal class. I have class 'Item', 'ContentBase' and 'Test'. 'ContentBase' is abstract and 'Test' derives from it. 'ContentBase' has a property 'Item' that links to an instance of 'Item'. So that 'Test.Item' or any class that derives from 'ContentBase' has an 'Item' navigation property. In my DB every record for Test has a matching record for Item. public class Item { public int Id { get; set;} } public abstract class ContentBase { public int ContentId { get; set;} public int Id { get; set;} public Item Item { get; set;} } public class Test : ContentBase { public string Name { get; set;} } now some init code public void SomeInitFunction() { var itemConfig = new EntityConfiguration<Item>(); itemConfig.HasKey(p => p.Id); itemConfig.Property(p => p.Id).IsIdentity(); this.ContextBuilder.Configurations.Add(itemConfig); var testConfig = new EntityConfiguration<Test>(); testConfig.HasKey(p => p.ContentId); testConfig.Property(p => p.ContentId).IsIdentity(); // the problem testConfig.Relationship(p => p.Item).HasConstraint((p, q) => p.Id == q.Id); this.ContextBuilder.Configurations.Add(testConfig); } This gives an error: A key is registered for the derived type 'Test'. Keys must be registered for the root type 'ContentBase'. anyway i try i get an error. What am i a doing wrong?

  • How do I remove HTML that I place dynamically with JQuery

    - by Vivek
    lets say i have fallowing html... <li><a href="#" id='DataSheets' >Data Sheets</a><font class="leftNavHitsFont">- (1)</font></li> <li><a href="#" id='ApplicationNotes' >Application Notes</a><fontclass="leftNavHitsFont">- (6)</font></li> what i want to do is, add a html on onclick of these links, if you click on first link output should look like <li><span>ajksdfskaj</span></li> <li><a href="#" id='ApplicationNotes' >Application Notes</a><fontclass="leftNavHitsFont">- (6)</font></li> means hide the original html of that li and append new html for ex. a span as i have written above...and if i clicked on second link the first li should get it's original html and appended html should get removed and get appended to current li bieng clicked..in this case output should look like... <li><a href="#" id='DataSheets' >Data Sheets</a><font class="leftNavHitsFont">- (1)</font></li> <li><span>ajksdfskaj</span></li> i tried to achieve this thing through variuos way...but could not find out the correct way.. please help me out guys..

  • How to write a flexible modular program with good interaction possibilities between modules?

    - by PeterK
    I went through answers on similar topics here on SO but could't find a satisfying answer. Since i know this is a rather large topic, i will try to be more specific. I want to write a program which processes files. The processing is nontrivial, so the best way is to split different phases into standalone modules which then would be used as necessary (since sometimes i will be only interested in the output of module A, sometimes i would need output of five other modules, etc). The thing is, that i need the modules to cooperate, because the output of one might be the input of another. And i need it to be FAST. Moreover i want to avoid doing certain processing more than once (if module A creates some data which then need to be processed by module B and C, i don't want to run module A twice to create the input for modules B,C ). The information the modules need to share would mostly be blocks of binary data and/or offsets into the processed files. The task of the main program would be quite simple - just parse arguments, run required modules (and perhaps give some output, or should this be the task of the modules?). I don't need the modules to be loaded at runtime. It's perfectly fine to have libs with a .h file and recompile the program every time there is a new module or some module is updated. The idea of modules is here mainly because of code readability, maintaining and to be able to have more people working on different modules without the need to have some predefined interface or whatever (on the other hand, some "guidelines" on how to write the modules would be probably required, i know that). We can assume that the file processing is a read-only operation, the original file is not changed. Could someone point me in a good direction on how to do this in C++ ? Any advice is wellcome (links, tutorials, pdf books...).
