  • Horizontal menu vertical padding on anchor tag doesn't take affect

    - by Levi
    I am wondering why in the following example the top and bottom padding has no affect on the anchor tag while the left and right does? <ul id="nav"> <li><a href="#">One</a></li> <li><a href="#">Two</a></li> <li><a href="#">Three</a></li> <li><a href="#">Four</a></li> <li><a href="#">Five</a></li> </ul> #nav{ list-style:none; } #nav li{ border:1px solid #666; display:inline; /*If you do it this way you need to set the top and bottom padding to be the same here as under #nav li a padding:8px 0; */ } #nav li a{ padding:8px 16px; } Example: Link So my main question is, why does the top and bottom padding not have an effect on the list items while the left and right do? I did try this out with a float instead of a display:inline on the list item and it worked as I expected it to. So I guess if I had a secondary question it would be what is the difference between a float:left; and a display:inline? I was reading the float spec and it sounds like a float is still a box online inline so somewhat like inline-block? I appreciate any input, this isn't really something I need to know to finish a project or anything, but I would like to know why. Thanks Levi

  • Django: Complex filter parameters or...?

    - by minder
    This question is connected to my other question but I changed the logic a bit. I have models like this: from django.contrib.auth.models import Group class Category(models.Model): (...) editors = ForeignKey(Group) class Entry(models.Model): (...) category = ForeignKey(Category) Now let's say User logs into admin panel and wants to change an Entry. How do I limit the list of Entries only to those, he has the right to edit? I mean: How can I list only those Entries which are assigned to a Category that in its "editors" field has one of the groups the User belongs to? What if User belongs to several groups? I still need to show all relevant Entries. I tried experimenting with changelist_view() and queryset() methods but this problem is a bit too complex for me. I'm also wondering if granular-permissions could help me with the task, but for now I have no clue. I came up only with this: First I get the list of all Groups the User belongs to. Then for each Group I get all connected Categories and then for each Category I get all Entries that belong to these Categories. Unfortunately I have no idea how to stitch everything together as filter() parameters to produce a nice single QuerySet.

  • AbstractMethodError when invoking createArrayOf, with postgresql 8.4 jdbc4 and JBoss 5.1GA

    - by Francesco
    Hi, when using this method public List<Field> getFieldWithoutId(List<Integer> idSections) throws Exception { try { Connection conn = this.getConnection(); Array arraySections = conn.createArrayOf("int4", idSections.toArray()); this.log.info("Recupero field"); List<Field> fields = this.getJdbcTemplate().query(getFieldWithoutIdQuery, new Object[] {arraySections},ParameterizedBeanPropertyRowMapper.newInstance(Field.class)); /*if (!conn.isClosed()) conn.close(); */ releaseConnection(conn); return fields; } catch (Exception e) { e.printStackTrace(); throw new Exception("Errore."); } } I have an exception at conn.createArrayOf("int4", idSections.toArray());.

    - by newName
    I have a web form that will dynamically create a number of checkboxlist filled with data based on the number of row in database. Then this is added to a placeholder to be displayed. theres a button when clicked, will add the selected check boxes value into database but right now when the button is clicked and after the postback, the page will show the error "System.NullReferenceException". the following code is written in Page_Load in (!Page.IsNotPostBack) and in a loop that will dynamically create a number of checkboxlist: CheckBoxLis chkContent = new CheckBoxList(); chkContent.ID = chkIDString; //chkIDString is an incremental int based on the row count chkContent.RepeatDirection = RepeatDirection.Horizontal; foreach (List<t> contentList in List<t>) //data retrieved as List<t> using LINQ { ListItem contents = new ListItem(); contents.Text = contentList.Title; contents.Value = contentList.contentID.ToString(); chkContent.Items.Add(contents); } plcSchool.Controls.Add(chkContent); //plcSchool is my placeholder plcSchool.Controls.Add(new LiteralControl("<br>")); protected void btnAdd_Click(object sender, EventArgs e) { CheckBoxList cbl = Page.FindControl("chkContent4") as CheckBoxList; Response.Write(cbl.SelectedValue.ToString()); // now im just testing to get the value from one of the checkboxlist } Anyone able to help, as it seems the controls are not recreated after the postback, therefore it can't find the control and throwing the null reference exception.

  • Loading through Ajax request and bookmarked URL

    - by Varun
    I am working on a ticket system, having the following requirement: The home page is divided into two sections: Sec-1. Some filter options are shown here.(like closed-tickets, open-tickets, all-tickets, tickets-assigned-to-me etc.). You can select one or more of these filters. sec-2. List of tickets satisfying above filters will be displayed here. Now this is what I want: As I change the filters -- the change should be reflected in the URL, so that one is able to bookmark it. -- an ajax request will go and list of tickets satisfying the selected filters will be updated in sec-2. I want the same code to be used to load the tickets in both ways- (a) by selecting that set of filters and (b) by using the bookmark to reload the page. I have little idea on how to do it: The URL will contain the selected filters.(appended after #) changing filters on the page will modify the hash part of URL and call a function (say ajaxHandler()) to parse the URL to get the filters and then make an ajax request to get the list of tickets to be displayed in section2. and I will call the same function ajaxHandler() in window.onload. Is this the way? Any suggestions?

  • (1 2 3 . #<void>)- heapsort

    - by superguay
    Hello everybody: I tried to implement a "pairing heap" with all the regular operations (merge, delete-min etc.), then I've been requested to write a function that would sort a list using my newly constructed heap implementation. Unfortunately it seems that someting goes wrong... Here's the relevant code: (define (heap-merge h1 h2) (cond ((heap-empty? h1) h2) ((heap-empty? h2) h1) (else (let ((min1 (heap-get-min h1)) (min2 (heap-get-min h2))) (if ((heap-get-less h1) min1 min2) (make-pairing-heap (heap-get-less h1) min1 (cons h2 (heap-get-subheaps h1))) (make-pairing-heap (heap-get-less h1) min2 (cons h1 (heap-get-subheaps h2)))))))) (define (heap-insert element h) (heap-merge (make-pairing-heap (heap-get-less h) element '()) h)) (define (heap-delete-min h) (define (merge-in-pairs less? subheaps) (cond ((null? subheaps) (make-heap less?)) ((null? (cdr subheaps)) (car subheaps)) (else (heap-merge (heap-merge (car subheaps) (cadr subheaps)) (merge-in-pairs less? (cddr subheaps)))))) (if (heap-empty? h) (error "expected pairing-heap for first argument, got an empty heap ") (merge-in-pairs (heap-get-less h) (heap-get-subheaps h)))) (define (heapsort l less?) (let aux ((h (accumulate heap-insert (make-heap less?) l))) (if (not (heap-empty? h)) (cons (heap-get-min h) (aux (heap-delete-min h)))))) And these are some selectors that may help you to understand the code: (define (make-pairing-heap less? min subheaps) (cons less? (cons min subheaps))) (define (make-heap less?) (cons less? '())) (define (heap-get-less h) (car h)) (define (heap-empty? h) (if (null? (cdr h)) #t #f)) Now lets get to the problem: When i run 'heapsort' it returns the sorted list with "void", as you can see: (heapsort (list 1 2 3) <) (1 2 3 . #)..HOW CAN I FIX IT? Regards, Superguay

  • Displaying single-instance business object data on SSRS

    - by Lachlan
    I have a SQL Server Reporting Services local (i.e. RDLC) report displayed in a ReportViewer, with two subreports. I am using business objects to populate the datasets. What is the best way to populate single-instance data on my report, e.g. a dynamic title, or a text box that lists a calculated value, not based on the report data? I am currently displaying data using the following style: public class MyRecordList { string Name { get; set; } List<MyRecord> Records { get; set;} } public MyRecord { string Description { get; set;} string Value { get; set;} } I set the datasource to the Records in an instance of MyRecordsList, and they print out find in a table. But adding a textbox and and referring to Name displays nothing. I also tried turning Name into a List, and referring to the first in the list, using: =First(Fields!Name.Value, "Report1_MyRecordList") but still nothing is printed on the report.

    I have an XML structure that has many doc nodes, and each node may have zero or more extract paragraphs (paras). <doc> <docitem>3</docitem> <docid>129826</docid> <doctitle>sample title</doctitle> <docdatetime>2009-07-03T16:59:00</docdatetime> <collectdatetime>2009-07-03T16:59:23</collectdatetime> <summary> <summarytext>sample summary</summarytext> </summary> <paras> <paraitemcount>2</paraitemcount> <para> <paraitem>1</paraitem> <paratext>sample text 1</paratext> </para> <para> <paraitem>2</paraitem> <paratext>sample text 2</paratext> </para> </paras> </doc> <doc> ... </doc> I also has some Linq code to populate some Document objects: List<Document> documentsList = (from doc in xmlDocument.Descendants("doc") select new Document { DocId = doc.Element("docid").Value, DocTitle = doc.Element("doctitle").Value, DocDateTime = DateTime.Parse(doc.Element("docdate").Value), DocSummary = doc.Element("summary").Value, DocParas = "" ///missing code to populate List<string> } ).ToList<Document>(); Is it possible add all the paras nodes into the Document.DocParas List<string> using Linq and Xpath, or should I do this task in a different way?

  • jQuery autocomplete: taking JSON input and setting multiple fields from single field

    - by Sly
    I am trying to get the jQuery autocomplete plugin to take a local JSON variable as input. Once the user has selected one option from the autocomplete list, I want the adjacent address fields to be autopopulated. Here's the JSON variable that declared as a global variable in the of the HTML file: var JSON_address={"1":{"origin":{"nametag":"Home","street":"Easy St","city":"Emerald City","state":"CA","zip":"9xxxx"},"destination":{"nametag":"Work","street":"Factory St","city":"San Francisco","state":"CA","zip":"94104"}},"2":{"origin":{"nametag":"Work","street":"Umpa Loompa St","city":"San Francisco","state":"CA","zip":"94104"},"destination":{"nametag":"Home","street":"Easy St","city":"Emerald City ","state":"CA","zip":"9xxxx"}}}</script> I want the first field to display a list of "origin" nametags: "Home", "Work". Then when "Home" is selected, adjacent fields are automatically populated with Street: Easy St, City: Emerald City, etc. Here's the code I have for the autocomplete: $(document).ready(function(){ $("#origin_nametag_id").autocomplete(JSON_address, { autoFill:true, minChars:0, dataType: 'json', parse: function(data) { var rows = new Array(); for (var i=0; i<=data.length; i++) { rows[rows.length] = { data:data[i], value:data[i].origin.nametag, result:data[i].origin.nametag }; } return rows; } }).change(function(){ $("#street_address_id").autocomplete({ dataType: 'json', parse: function(data) { var rows = new Array(); for (var i=0; i<=data.length; i++) { rows[rows.length] = { data:data[i], value:data[i].origin.street, result:data[i].origin.street }; } return rows; } }); }); }); So this question really has two subparts: 1) How do you get autocomplete to process the multi-dimensional JSON object? (When the field is clicked and text entered, nothing happens - no list) 2) How do you get the other fields (street, city, etc) to populate based upon the origin nametag sub-array? Thanks in advance!

  • How to sort linq result by most similarity/equality

    - by aNui
    I want to do a search for Music instruments which has its informations Name, Category and Origin as I asked in my post. But now I want to sort/group the result by similarity/equality to the keyword such as. If I have the list { Drum, Grand Piano, Guitar, Guitarrón, Harp, Piano} << sorted by name and if I queried "p" the result should be { Piano, Grand Piano, Harp } but it shows Harp first because of the source list's sequence and if I add {Grand Piano} to the list and query "piano" the result shoud be like { Piano, Grand Piano } or query "guitar" it should be { Guitar, Guitarrón } here's my code static IEnumerable<MInstrument> InstrumentsSearch(IEnumerable<MInstrument> InstrumentsList, string query, MInstrument.Category[] SelectedCategories, MInstrument.Origin[] SelectedOrigins) { var result = InstrumentsList .Where(item => SelectedCategories.Contains(item.category)) .Where(item => SelectedOrigins.Contains(item.origin)) .Where(item => { if ( (" " + item.Name.ToLower()).Contains(" " + query.ToLower()) || item.Name.IndexOf(query) != -1 ) { return true; } return false; } ) .Take(30); return result.ToList<MInstrument>(); } Or the result may be like my old self-invented algorithm that I called "by order of occurence", that is just OK to me. And the further things to do is I need to search the Name, Category or Origin such as. If i type "Italy" it should found Piano or something from Italy. Or if I type "string" it should found Guitar. Is there any way to do those things, please tell me. Thanks in advance.

  • ‘Empty’ results from MQL Query. Freebase Schema: /film/film/starring & /film/actor/film

    - by user1879631
    First post here, so I hope this is enough detail. I started using freebase-python today to get film information for a program that I’m working on. One thing that I need to grab is a list of actors that starred in a film. I’ve followed some tutorials and guides on the way to do this, and can get a list of films for a director or the director of a film, but when I try to do the same with an actor or a film’s cast, I get ‘null’ results. I have the same problem in both Python and the Freebase MQL Query Editor, and you can see what I've tried below. Links to all of the examples below written in the editor can be found here, as Stack Overflow wouldn't let me post links underneath each example on my first post! Working director query in Python: import freebase fb = freebase.mqlread q = {'type':'/film/film', 'name':'Inception', 'directed_by':[]} fb(q) Working director's filmography query in Python: import freebase fb = freebase.mqlread q = {'type':'/film/director', 'name': 'Christopher Nolan', 'film':[]} fb(q) Based on these tests, I tried to do the same with actors, but with odd results: Not working cast list query in Python: import freebase fb = freebase.mqlread q = {'type':'/film/film', 'name':'Inception', 'starring':[]} fb(q) Not working actor's filmography query in Python: import freebase fb = freebase.mqlread q = {'type':'/film/actor', 'name':'Leonardo DiCaprio', 'film':[]} fb(q) Strangely, I get an accurate number of actors/films back, but no names. Does anyone have any idea what the problem might be? Thanks a lot, I'd appreciate any advice.

  • The subsets-sum problem and the solvability of NP-complete problems

    - by G.E.M.
    I was reading about the subset-sums problem when I came up with what appears to be a general-purpose algorithm for solving it: (defun subset-contains-sum (set sum) (let ((subsets) (new-subset) (new-sum)) (dolist (element set) (dolist (subset-sum subsets) (setf new-subset (cons element (car subset-sum))) (setf new-sum (+ element (cdr subset-sum))) (if (= new-sum sum) (return-from subset-contains-sum new-subset)) (setf subsets (cons (cons new-subset new-sum) subsets))) (setf subsets (cons (cons element element) subsets))))) "set" is a list not containing duplicates and "sum" is the sum to search subsets for. "subsets" is a list of cons cells where the "car" is a subset list and the "cdr" is the sum of that subset. New subsets are created from old ones in O(1) time by just cons'ing the element to the front. I am not sure what the runtime complexity of it is, but appears that with each element "sum" grows by, the size of "subsets" doubles, plus one, so it appears to me to at least be quadratic. I am posting this because my impression before was that NP-complete problems tend to be intractable and that the best one can usually hope for is a heuristic, but this appears to be a general-purpose solution that will, assuming you have the CPU cycles, always give you the correct answer. How many other NP-complete problems can be solved like this one?

  • Silverlight 4, Out of browser, Printing, Automatic updates

    - by minal
    I have a very critial business application presently running using Winforms. The application is a very core UI shell. It accepts input data, calls a webservice on my server to do the computation, displays the results on the winforms app and finally send a print stream to the printer. Presently the application is deployed using Click-once. Moving forward, I am trying to contemplate wheather I should move the application into a Silverlight application. Couple of reasons I am thinking silverlight. Gives clients the feel that it is a cloud based solution. Can be accessed from any PC. While the clickonce app is able to do this as well, they have to install an app, and when updates are available they have to click "Yes" to update. The application presently has a drop down list of customers, this list has expanded to over 3000 records. Scrolling through the list is very painful. With Silverlight I am thinking of the auto complete ability. Out of the browser - this will be handy for those users who use the app daily. I haven't used Silverlight previous hence looking for some expert advice on a few things: Printing - does silverlight allow sending raw print data to the printer. The application prints to a Zebra Thermal label printer. I have to send raw bytes to the printer with the commands. Can this be done with SL, or will it always prompt the "Print" dialog? Out of browser - when SL apps are installed as out of browser, how to updates come through, does the app update automatically or is the user prompted to opt for update?

  • WCF- "The underlying connection was closed: The connection was closed unexpectedly"

    - by SumGuy
    Hi there. I'm recieving that wonderfuly ambiguous error message when using one of my webmethods on my WCF webservice. As that error message doesn't provide any explanation whatsoever allow me to post my theory. I believe it may have something to do with the return type I'm using I have a Types DLL which is refrenced in both the webservice and the client. In this DLL is the base class ExceptionMessages. There is a child of this class called DrawingExcepions. Here is some code: public class ExceptionMessages { public object[] ReturnValue { get; set; } } public class DrawingExceptions : ExceptionMessages { private List<DrawingException> des = new List<DrawingException>(); } public class DrawingException { public Exception ExceptionMsg { get; set; } public List<object> Errors { get; set; } } The using code: [OperationContract] ExceptionMessages createNewBom(Bom bom, DrawingFiles dfs); public ExceptionMessages createNewBOM(Bom bom, DrawingFiles dfs) { return insertAssembly(bom, dfs); } public DrawingExceptions insertAssembly(Bom bom, DrawingFiles dfs) { DrawingExceptions des = new DrawingExceptions(); foreach (DrawingFile d in dfs.drawingFiles) { DrawingException temp = insertNewDrawing(bom, d); if (temp != null) des.addDrawingException(temp); if (d.Child != null) des.addDrawingException(insertAssembly(bom, d.Child)); } return des; } Returns to: ExceptionMessages ems = client.createNewBom(bom, currentDFS); if (ems is DrawingExceptions) { } Basically the return type from the webmethod is ExceptionMessages however I would usually be sending the child class back instead. My only idea is that it's the child that's causing the error but as far as I've read, this should have no effect. Has anyone got any ideas what could be going wrong here? If any more info is required, just ask :) Thanks.

  • WPF: Change the style of a ViewBox depending upon the amount of data

    - by Brett Rigby
    Hi there, I have a WPF app that has a ViewBox to display the items in my collection, diplaying a 2-column grid for my results. What I'd like to do is, depending on the number of items in my collection, change the number of columns. E.g if there are < 10 items in the list, then show them in just 1 column; If there are 10 items in my list, then show them in 2 columns; If there are 20 items in my list, then show 3 columns. Here's what I have at present: <Viewbox> <ItemsControl ItemsSource="{Binding myCollection}" Style="{DynamicResource myStyle}" /> </Viewbox> Here's what myStyle currently defines: <Style x:Key="myStyle" TargetType="{x:Type ItemsControl}"> <Setter Property=ItemsControl.ItemsPanel"> <Setter.Value> <ItemsPanelTemplate> <UniformGrid Columns="2" /> </ItemsPanelTemplate> </Setter.Value> </Setter> </Style> How can I make this code work to the above requirement? Thanks.

I want to loop over the list foo and print each element as it's own table. % \documentclass[a4paper]{article} \usepackage[OT1]{fontenc} \usepackage{longtable} \usepackage{geometry} \usepackage{Sweave} \geometry{left=1.25in, right=1.25in, top=1in, bottom=1in} \listfiles \begin{document} <<label=start, echo=FALSE, include=FALSE>>= startt<-proc.time()[3] library(RODBC) library(psych) library(xtable) library(plyr) library(ggplot2) options(width=80) #Produce some example data, here I'm creating some dummy dataframes and putting them in a list foo<-list() foo[[1]]<-data.frame(GRP=c(rep("AA",10), rep("Aa",10), rep("aa",10)), X1=rnorm(30), X2=rnorm(30,5,2)) foo[[2]]<-data.frame(GRP=c(rep("BB",10), rep("bB",10), rep("BB",10)), X1=rnorm(30), X2=rnorm(30,5,2)) foo[[3]]<-data.frame(GRP=c(rep("CC",12), rep("cc",18)), X1=rnorm(30), X2=rnorm(30,5,2)) foo[[4]]<-data.frame(GRP=c(rep("DD",10), rep("Dd",10), rep("dd",10)), X1=rnorm(30), X2=rnorm(30,5,2)) @ \title{Docuemnt to test putting a variable number of tables into a sweave Document} \author{"Paul Hurley"} \maketitle \section{Text} This document was created on \today, with \Sexpr{print(version$version.string)} running on a \Sexpr{print(version$platform)} platform. It took approx \input{time} sec to process. <<label=test, echo=FALSE, results=tex>>= cat("Foo") @ that was a test, so is this <<label=table1test, echo=FALSE, results=tex>>= print(xtable(foo[[1]])) @ \newpage \subsection{Tables} <<label=Tables, echo=FALSE, results=tex>>= for(i in seq(foo)){ cat("\n") cat(paste("Table_",i,sep="")) cat("\n") print(xtable(foo[[i]])) cat("\n") } #cat("<<label=endofTables>>= ") @ <<label=bye, include=FALSE, echo=FALSE>>= endt<-proc.time()[3] elapsedtime<-as.numeric(endt-startt) @ <<label=elapsed, include=FALSE, echo=FALSE>>= fileConn<-file("time.tex", "wt") writeLines(as.character(elapsedtime), fileConn) close(fileConn) @ \end{document} Here, the table1test chunk works as expected, and produced a table based on the dataframe in foo[[1]], however the loop only produces Table(underscore)1.... Any ideas what I'm doing wrong ?

  • Average of two strings in alphabetical/lexicographical order

    - by Bemmu
    Suppose you take the strings 'a' and 'z' and list all the strings that come between them in alphabetical order: ['a','b','c' ... 'x','y','z']. Take the midpoint of this list and you find 'm'. So this is kind of like taking an average of those two strings. You could extend it to strings with more than one character, for example the midpoint between 'aa' and 'zz' would be found in the middle of the list ['aa', 'ab', 'ac' ... 'zx', 'zy', 'zz']. Might there be a Python method somewhere that does this? If not, even knowing the name of the algorithm would help. I began making my own routine that simply goes through both strings and finds midpoint of the first differing letter, which seemed to work great in that 'aa' and 'az' midpoint was 'am', but then it fails on 'cat', 'doggie' midpoint which it thinks is 'c'. I tried Googling for "binary search string midpoint" etc. but without knowing the name of what I am trying to do here I had little luck.

  • changing user permissions dynamically

    - by ephieste
    I am designing a system on SharePoint. There is a approval list for the items. The members can approve, reject and edit the items. One from approval list has to fill the "assigned to" field in the item while approving it. The user who is added to "assigned to" field should able to edit the content of the item after it is approved. So, how can I give the edit permission to the users after they are added assigned to field of a specific item? The situation is: approval list: A, B ,C (edit, view permission) users: x,y,z .... (no permission, view after approval) items: item1, item2, item3.... items are invisible. A approved the item1 and added X to "assigned to" field. It means This item is under X's responsibility. But X hasn't got edit permission. we can't give edit permission to X for every item. He should edit the items after he is written into the "assigned to" field. How can I create this workflow in SharePoint? Please urgent help needed.

  • Trigger for ComboBox in Silverlight

    - by Budda
    Is there any possibility to display selected item of the ComboBox (after popup closing) in a way that is different from its displaying in DropDown List (There are players number and name in the dropdown list, but after list closing I want to see only its number). How can I change a background for the player with some Flag? As far as I know, all of that can be done with triggers, but are they supported in Silverlight 4, VS2010, Silverlight Toolkit 4? In my case the following code <ComboBox ItemsSource="{Binding PlayersAll}" SelectedItem="{Binding Path=SelectedPlayer, Mode=TwoWay}" > <ComboBox.ItemTemplate> <DataTemplate> <ToolkitControls:WrapPanel Orientation="Horizontal"> <TextBlock Text="{Binding TeamNumber}"/> <TextBlock Text=" - "/> <TextBlock Text="{Binding ShortName}"/> </ToolkitControls:WrapPanel> <DataTemplate.Triggers> <Trigger Property="HasError" Value="True"> <Setter Property="Background" TargetName="FlagSet" Value="Red"/> </Trigger> </DataTemplate.Triggers> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> gives an error: The property 'Triggers' does not exist on the type 'DataTemplate' in the XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation' what is wrong here? Here are my namespaces: xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" xmlns:ToolkitControls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Toolkit"

  • For "draggable" div tags that are NOT nested: JQuery/JavaScript div tag “containment” approach/algor

    - by Pete Alvin
    Background: I've created an online circuit design application where .draggable() div tags are containers that contain smaller div containers and so forth. Question: For any particular div tag I need to quickly identify if it contains other div tags (that may in turn contain other div tags). -- Since the div tags are draggable, in the DOM they are NOT nested inside each other but I think are absolutely positioned. So I think that a "hit testing" approach is the only way to determine containment, unless there is some "secret" routine built-in somewhere that could help with this. I've searched JQuery and I don't see any built-in routine for this. Does anyone know of an algorithm that's quicker than O(n^2)? Seems like I have to walk the list of div tags in an outer loop (n) and have an inner loop (another n) to compare against all other div tags and do a "containment test" (position, width, height), building a list of contained div tags. That's n-squared. Then I have to build a list of all nested div tags by concatenating contained lists. So the total would be O(n^2)+n. There must be a better way?
