  • jQueryUI dialog width

    - by user35295
    Fiddle Full Screen Example I use jQuery dialog to open tables. Some of them have a large amount of text and they tend to be too long and go way off the screen. How can I make the dialog wider if the table is too long like the first one in the fiddle? I've tried width:'auto' but it seems to just occupy the entire screen. HTML: <button class='label'>Click</button><div class='dialog'><p><table>.....</table></div> <button class='label'>Click</button><div class='dialog'><p><table>.....</table></div> Javascript: $(document).ready(function(){ $('.label').each(function() { var dialogopen = $(this).next(".dialog"); dialogopen.dialog({width:'auto',autoOpen: false,modal: true, open: function(){ jQuery('.ui-widget-overlay').bind('click',function(){ dialogopen.dialog('close'); }) } }); $(this).click(function(){ dialogopen.dialog('open'); return false; } ); }); });

  • jQuery: How do I rewrite .after( content, content )?

    - by Evan Carroll
    I've got this form working, but according to my previous question it might not be supported: it isn't in the docs either way -- but the intention is pretty obvious in the code. $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ) , $('<span>OEM</span>') /*Notice this (a second) argument */ ); What this does is insert <div class="little check"> with a simple .click() callback, followed by a sibling of <span>OEM</span>. How else can I write this then? I'm having difficulty conjuring something working by chaining any combination of .after(), and .insertAfter()? I would expect this to work, but it doesn't: $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ).after ( $('<span>OEM</span>') ) ); I would also expect this to work, but it doesn't: $(".section.warranty .warranty_checks :last").after( $('<span>OEM</span>').insertAfter( $('<div class="little check" />').click( function () { alert('hi') } ) ); );

  • Why can't I pass an object of type T to a method on an object of type <? extends T>?

    - by Matt
    In Java, assume I have the following class Container that contains a list of class Items: public class Container<T> { private List<Item<? extends T>> items; private T value; public Container(T value) { this.value = value; } public void addItem(Item item) { items.add(item); } public void doActions() { for (Item item : items) { item.doAction(value); } } } public abstract class Item<T> { public abstract void doAction(T item); } Eclipse gives the error: The method doAction(capture#1-of ? extends T) in the type Item is not applicable for the arguments (T) I've been reading generics examples and various postings around, but I still can't figure out why this isn't allowed. Eclipse also doesn't give any helpful tips in its proposed fix, either. The variable value is of type T, why wouldn't it be applicable for ? extends T?.

  • Creating a Variable From Two Others

  • C ++ virtual function

    - by user2950788
    masters of C++. I am trying to implement polymorphism in C++. I want to write a base class with a virtual function and then redefine that function in the child class. then demonstrate dynamic binding in my driver program. But I just couldn't get it to work. I know how to do it in C#, so I figured that I might have made some syntactical mistakes where I had used C#'s syntax in my C++ code, but these mistakes are not obvious to me at all. So I'd greatly appreciate it if you would correct my mistakes. class polyTest { public: polyTest(); virtual void type(); virtual ~polyTest(); }; void polyTest::type() { cout << "first gen"; } class polyChild: public polyTest { public: void type(); }; void polyChild::type() { cout << "second gen"; } int main() { polyChild * ptr1; polyChild * ptr2; ptr1 = new polyTest(); ptr2 = new polyChild(); ptr1 -> type(); ptr2 -> type(); }

  • Unexpected crash while using looking phone numbers in iPhone address book

    - by FX
    I have a rather unexpected result with the following code: ABAddressBookRef addressBook = ABAddressBookCreate(); CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook); CFIndex nPeople = ABAddressBookGetPersonCount(addressBook); NSLog (@"npeople = %d = %d", nPeople, CFArrayGetCount(people)); for (CFIndex i = 0; i < nPeople; i++) { ABRecordRef record = CFArrayGetValueAtIndex(people,i); ABMultiValueRef numbers = ABRecordCopyValue(record, kABPersonPhoneProperty); CFIndex count = ABMultiValueGetCount(numbers); NSLog (@"%d %d", i, count); } I never reach the second NSLog, it crashes on the call to ABMultiValueGetCount with: : * -[NSCFString count]: unrecognized selector sent to instance 0x383e72f4 : Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '** -[NSCFString count]: unrecognized selector sent to instance 0x383e72f4' In short, it's behaving as if my "numbers" variable was an NSString. While I wrote the code above myself, the same can be found in many examples on the web. Does someone here spot anything wrong with it? Oh, and also: it only crashes in Release mode (in debug mode, all is fine).

  • ASP.NET Custom Control - Template Allowing Literal Content

    - by Bob Fincheimer
    I want my User Control to be able to have Literal Content inside of it. For Example: <fc:Text runat="server">Please enter your login information:</fc:Text> Currently the code for my user control is: <ParseChildren(True, "Content")> _ Partial Public Class ctrFormText Inherits FormControl Private _content As ArrayList <PersistenceMode(PersistenceMode.InnerDefaultProperty), _ DesignerSerializationVisibility(DesignerSerializationVisibility.Content), _ TemplateInstance(TemplateInstance.Single)> _ Public Property Content() As ArrayList Get If _content Is Nothing Then Return New ArrayList End If Return _content End Get Set(ByVal value As ArrayList) _content = value End Set End Property Protected Overrides Sub CreateChildControls() If _content IsNot Nothing Then ctrChildren.Controls.Clear() For Each i As Control In _content ctrChildren.Controls.Add(i) Next End If MyBase.CreateChildControls() End Sub End Class And when I put text inside this control (like above) i get this error: Parser Error Message: Literal content ('Please enter your login information to access CKMS:') is not allowed within a 'System.Collections.ArrayList'. This control could have other content than just the text, so making the Content property an attribute will not solve my problem. I found in some places that I need to implement a ControlBuilder Class, along with another class that implements IParserAccessor. Anyway I just want my default "Content" property to have all types of controls allowed in it, both literal and actual controls.

  • Bind two images together to be dragged

    - by Ryan Beaulieu
    I'm looking for some help with a script to drag two images together at once. I currently have a script that allows me to drag thumbnail images into a collection bin to be saved later. However, some of my thumbnails have an image positioned over the top of them to represent these thumbnail images as "unknown" plants. I was wondering if someone could point me in the right direction as to how I would go about binding these two images together to be dragged. Here is my code: $(document).ready(function() { var limit = 16; var counter = 0; $("#mainBin1, #mainBin2, #mainBin3, #mainBin4, #mainBin5, #bin_One_Hd, #bin_Two_Hd, #bin_Three_Hd, #bin_Four_Hd, #bin_Five_Hd").droppable({ accept: ".selector, .plant_Unknown", drop: function(event, ui) { counter++; if (counter == limit) { $(this).droppable("disable"); } $(this).append($(ui.draggable).clone()); $("#cbOptions").show(); $(".item").draggable({ containment: "parent", grid: [72,72], }); } }); $(".selector").draggable({ helper: "clone", revert: "invalid", revertDuration: 700, opacity: 0.75, }); $(".plant_Unknown").draggable({ helper: "clone", revert: "invalid", revertDuration: 700, opacity: 0.75, }); }); Any help would be greatly appreciated. Thanks. EDIT: Website

  • JQuery event that triggers after CSS is loaded?

    - by Dave
    (I posted this on the jquery forums but it's still awaiting moderation, so I thought I'd try my luck here since stackoverflow is so awesome. If I get an answer I'll post it here.) Maybe someone can help me with this, I have a couple of links on my page (inside a <div id="theme-selector">) which allow you to change the CSS stylesheets: $('#theme-selector a').click(function(){ var path = $(this).attr('href'); $('head link').remove(); $('head').append('<link type="text/css" href="'+path+'" rel="stylesheet" />'); return false; }); Now, after I've changed the style on the page, I want to get the new background color, using the following code (which I put after the $('head').append call): var bgcolor = $('body').css('background-color'); alert(bgcolor); The problem is, I think, that it takes some time for the browser to download the new stylesheet and I sometimes get the old background color in my alert message. Is there some event I can bind that will only alert me after all the stylesheets are loaded on the page? At the moment, all I can think of is using a setTimeout(function(){}, 5000); which isn't great, because what if it takes longer/shorter to load all the CSS on the page. Let me know if I need to clarify anything and I can provide more code. Thanks in advance.

  • Making a Delete and Reply button in Jquery

    - by Branko Ostojic
    this is my second post on the website. Of all other sites i tried, this one gave the most accurate and useful information! I'm in a bit of a trouble with buttons, i have a task to make an inbox and to add a "reply" and "delete" button into every instance of the message. I was indeed wandering if there is a better way to do that than forcing the HTML code into the script, because every message is dynamically generated. Any help and/or suggestions would be very appreciated!(The objects are called from a JSON file). $(document).ready(function(){ $.getJSON('public/js/data.json', function(json){ $.each(json.data, function(i, data){ var output = ''; if(data.from.id != '234' && data.from.name != 'Alan Ford'){ $("#inbox").append( output += '<div class="post">'+ '<div class="h1">'+data.from.name+' - '+data.subject+'</div>'+ //this gives the name of the person who sent the message and the subject '<div class="content">'+data.message_formatted+'</div>'+ //The content of the message //buttons should be squeezed left of the date //this gives the date of the message sent '<div class="time">'+data.date_sent_formatted.formatted+'</div>'+ '</div>' ); }}); }); }); var date_sent=convertToDateTime(); function delete_message(id){ console.log('Delete message with id: '+id); } function reply_message(id, sender){ console.log('Message id: '+id); console.log('Reply to: '+sender); } The complete code in the JSFiddle .

  • Changing UIViews during UIInterfaceOrientation on iPad

    - by FreeAppl3
    I am trying to change views on rotation because my views have to be significantly different from portrait to landscape. Now the code I am using works once then the app freezes when trying to rotate back. Either direction does not make a difference. For example: If I am in Landscape and rotate to portrait everything works great until I rotate back to landscape then it freezes and does absolutely nothing. Here is the code I am using to achieve this In my "viewDidLoad" method [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:) name:UIDeviceOrientationDidChangeNotification object:nil]; Then I call this for the rotation: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return YES; } - (void)didRotate:(NSNotification *)notification { UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation]; if ((orientation == UIDeviceOrientationLandscapeLeft) || (orientation == UIDeviceOrientationLandscapeLeft)) { // present the other viewController, it's only viewable in landscape [self.view addSubview:landScapeView]; } if ((orientation == UIDeviceOrientationLandscapeRight) || (orientation == UIDeviceOrientationLandscapeRight)) { // present the other viewController, it's only viewable in landscape [self.view addSubview:landScapeView]; } else if ((orientation == UIDeviceOrientationPortrait || (orientation == UIDeviceOrientationPortrait)) { // get rid of the landscape controller [self.view addSubview:portrait]; } else if ((orientation == UIDeviceOrientationPortraitUpsideDown || (orientation == UIDeviceOrientationPortraitUpsideDown)) { // get rid of the landscape controller [self.view addSubview:portrait]; } }

  • Dispose, when is it called?

    - by Snake
    Consider the following code: namespace DisposeTest { using System; class Program { static void Main(string[] args) { Console.WriteLine("Calling Test"); Test(); Console.WriteLine("Call to Test done"); } static void Test() { DisposeImplementation di = new DisposeImplementation(); } } internal class DisposeImplementation : IDisposable { ~DisposeImplementation() { Console.WriteLine("~ in DisposeImplementation instance called"); } public void Dispose() { Console.WriteLine("Dispose in DisposeImplementation instance called"); } } } The Dispose just never get's called, even if I put a wait loop after the Test(); invocation. So that quite sucks. I want to write a class that is straightforward and very easy to use, to make sure that every possible resource is cleaned up. I don't want to put that responsibilty to the user of my class. Possible solution: use using, or call Dispose myself(basicly the same). Can I force the user to use a using? Or can I force the dispose to be called? Calling GC.Collect(); after Test(); doesn't work either. Putting di to null doesn't invoke Dispose either. The Deconstructor DOES work, so the object get's deconstructed when it exits Test()

  • I'm confused about Polymorphism

    - by Vtanathip
    I'm know polymorphism rule that we can send it via parameter like this code interface Animal { void whoAmI(); } class A implements Animal{ @Override public void whoAmI() { // TODO Auto-generated method stub System.out.println("A"); } } class B implements Animal{ @Override public void whoAmI() { // TODO Auto-generated method stub System.out.println("B"); } } class RuntimePolymorphismDemo { public void WhoRU(List t){ System.out.println(t.getClass()); } public static void main(String[] args) { A a = new A(); B b = new B(); RuntimePolymorphismDemo rp = new RuntimePolymorphismDemo(); rp.WhoRU(a); rp.WhoRU(b); } } but List<Example> examples = new ArrayList<Example>(); This code,I'm don't understand why we must use List. why we can't use like this? ArrayList<Example> examples = new ArrayList<Example>(); Because when we use List we can't use method that only have in ArrayList class like trimToSize() and How I know when to use or not use?

  • Cannot connect to mysql via servlet

    - by JBoy
    Hi all I have been since 2 days trying to figure out why my servlet does not connect to the database MySql. I have mysql installed and working properly and eclipse. Whenever i try to etabilish a connection i get the ClassNotFoundException for the com.mysql.jdbc.Driver, which is actually properly imported, the connector i'm using is the mysql-connector-java5.1.14 added properly as external jar so everything seems fine. here's my code protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String dbUrl="jdbc:mysql://localhost:3306/test"; String username="root"; String password=""; try { Class.forName("com.mysql.jdbc.Driver").newInstance(); conn=DriverManager.getConnection(dbUrl); System.out.println("Connected!"); } catch (SQLException e) { e.printStackTrace(); System.out.println("not connected"); } catch(ClassNotFoundException x){ x.printStackTrace(); } catch(Exception e){ e.printStackTrace(); } } The stacktrace(part of): java.lang.ClassNotFoundException: com.mysql.jdbc.Driver at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1645) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1491) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:375) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:164) i'm following the connection steps from a published java book and also in forums and tutorials i just see the same code, cannot figure out why that Exception comes. On a normal application which does not run on the server the Exception isn't thrown and the connection (in the exact same way) its successfull. Do you have any advice?

  • What is the common way to program action listeners?

    - by Roman
    I just started to learn how to use action listeners. To my understanding it works in the following way: There are some classes which contains "addActionListener" method by default (for example classes for buttons). Using this method we add an action listener to an object. For example: listenedObject.addActionListener(listeningObject). When an action with the "listenedObject" is performed, the "actionPerformed" method of the "listeningObject" will be called. So, it means that when we program a class for the listeningObject, we need to put there "actionPerformed" method. What is not clear to me, should we create a new class for every object that we want to listen. It does not seem to me as an elegant solution. On the other hand, if we have one action listener class for all (or at least many) object, than we have a problem since a instance of this class will not know which object is calling the "actionPerformed" method (and we need to know that since actions performed by the actionPerformed differs depending on who is called for this method). In my opinion, for every listened object we need to create are "personal" action listener and we can do it by setting a specific value to the corresponding field of the action listener. But I am not sure that it is a standard way to go? How do usually people do it?

  • How to do something when AVQueuePlayer finishes the last playeritem

    I've got an AVQueuePlayer which I'm creating from an array of 4 AVPlayerItems, and it all plays fine. I want to do something when the last item in the queue finishes playing, I've looked a load of answers on here and this is the one that looks most promising for what I want: The best way to execute code AFTER a sound has finished playing In my button handler i have this code: static const NSString *ItemStatusContext; [thePlayerItemA addObserver:self forKeyPath:@"status" options:0 context:&ItemStatusContext]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerItemDidReachEnd) name:AVPlayerItemDidPlayToEndTimeNotification object:thePlayerItemA]; theQueuePlayer = [AVQueuePlayer playerWithPlayerItem:thePlayerItemA]; [theQueuePlayer play]; and then I have a function to handle playerItemDidReachEnd: - (void)playerItemDidReachEnd:(NSNotification *)notification { // Do stuff here NSLog(@"IT REACHED THE END"); } But when I run this I get an Internal Inconsistency Exception: An -observeValueForKeyPath:ofObject:change:context: message was received but not handled.

  • Foiled by path-dependent types

    - by Ladlestein
    I'm having trouble using, in one trait, a Parser returned from a method in another trait. The compiler complains of a type mismatch and it appears to me that the problem is due to the path-dependent class. I'm not sure how to get what I want. trait Outerparser extends RegexParsers { def inner: Innerparser def quoted[T](something: Parser[T]) = "\"" ~> something <~ "\"" def quotedNumber = quoted(inner.number) // Compile error def quotedLocalNumber = quoted(number) // Compiles just fine def number: Parser[Int] = ("""[1-9][0-9]*"""r) ^^ {str => str.toInt} } trait Innerparser extends RegexParsers { def number: Parser[Int] = ("""[1-9][0-9]*"""r) ^^ {str => str.toInt} } And the error: [error] /Path/to/MyParser.scala:6: type mismatch [error] found : minerals.Innerparser#Parser[Int] [error] required: Outerparser.this.Parser[?] [error] def quotedNumber = quoted(inner.number) I sort-of get the idea: each "something" method is defining a Parser type whose path is specific to the enclosing class (Outerparser or Innerparser). The "quoted" method of Outerparser expects an an instance of type Outerparser.this.Parser but is getting Innerparser#Parser. I like to be able to use quoted with a parser obtained from this class or some other class. How can I do that?

  • Is Using Tuples in my .NET 4.0 Code a Poor Design Decision?

    - by Jason Webb
    With the addition of the Tuple class in .net 4, I have been trying to decide if using them in my design is a bad choice or not. The way I see it, a Tuple can be a shortcut to writing a result class (I am sure there are other uses too). So this: public class ResultType { public string StringValue { get; set; } public int IntValue { get; set; } } public ResultType GetAClassedValue() { //..Do Some Stuff ResultType result = new ResultType { StringValue = "A String", IntValue = 2 }; return result; } Is equivalent to this: public Tuple<string, int> GetATupledValue() { //...Do Some stuff Tuple<string, int> result = new Tuple<string, int>("A String", 2); return result; } So setting aside the possibility that I am missing the point of Tuples, is the example with a Tuple a bad design choice? To me it seems like less clutter, but not as self documenting and clean. Meaning that with the type ResultType, it is very clear later on what each part of the class means but you have extra code to maintain. With the Tuple<string, int> you will need to look up and figure out what each Item represents, but you write and maintain less code. Any experience you have had with this choice would be greatly appreciated.

  • has_many :through default values

    - by David Lyod
    I have a need to design a system to track users memberships to groups with varying roles (currently three). class Group < ActiveRecord::Base has_many :memberships has_many :users, :through => :memberships end class Role < ActiveRecord::Base has_many :memberships has_many :users, :through => :memberships end class Membership < ActiveRecord::Base belongs_to :user belongs_to :role belongs_to :group end class User < ActiveRecord::Base has_many :memberships has_many :groups, :through => :memberships end Ideally what I want is to simply set @group.users << @user and have the membership have the correct role. I can use :conditions to select data that has been manually inserted as such : :conditions => ["memberships.grouprole_id= ? ", Grouprole.find_by_name('user')] But when creating the membership to the group the grouprole_id is not being set. Is there a way to do this as at present I have a somewhat repetitive piece of code for each user role in my Group model.

  • Retrieving Relationships from within two arrays of pointers

    - by DanF
    In a portion of a program I'm working on, I need to count all the times each person has worked on projects with each other person. Let's say we have "Employee" entities and "Session" entities. In each session, there are four project types, "A", "B", "C", & "D", each a many-to-many relationship to Employees. I'm making a loop to systematically review every person a selected person has worked with. First, I put all their project types in a single array, so it's easier to loop through, but by the time I ask the last nested Project for its Employee members, I get an "unrecognized selector" error. IBOutlet NSArrayController * list; int x; for(x = 0; x < [list count]; x++){ NSArray *A = [[list objectAtIndex:x] valueForKey:@"projectAs"]; NSArray *A = [[list objectAtIndex:x] valueForKey:@"projectBs"]; NSArray *A = [[list objectAtIndex:x] valueForKey:@"projectCs"]; NSArray *A = [[list objectAtIndex:x] valueForKey:@"projectDs"]; NSArray *masterList = [[NSArray alloc] initWithObjects: projectAs, projectBs, projectCs, projectDs, nil]; int y; for(y = 0; y < [masterList count]; y++){ int z; for(z = 0; z < [[masterlist objectAtIndex:y] count]; z++){ //And now to make an Array of this employee's partners on the selected object, to run comparisons on. //I also have an array of keys for each session's teams, so that's what I'm referencing here: NSArray * thisTeam = [list objectAtIndex:y] objectAtIndex:z] valueForKey:projectKey]; This throws an exception... namely, -[_NSFaultingMutableSet objectAtIndex:]: unrecognized selector sent to instance What's wrong with that last Array creation?

  • How to pass a parameter in a Javascript confirm function?

    - by Miles M.
    I have something like that in my code: <?php foreach($clients as $client): ?> <tr class="tableContent"> <td onclick="location.href='<?php echo site_url('clients/edit/'.$client->id ) ?>'"><?php echo $client->id ?></td> <td><a class='Right btn btn-danger' onClick="ConfirmMessage('client', <?php $client->id ?>,'clients')"> <i class="icon-remove-sign icon-white"></i> </a></td> </tr> <?php endforeach ?> that's actually the view. So when the user click on the delete button (thr one with the btn-danger class) I'd like him to confirm his choice with a javascript confirmation box message. You can find that script in the header <script> function ConfirmMessage(type, id, types) { if (confirm("Are you sure you want to delete this ",type," ?")) { // Clic sur OK document.location.href='<?php echo site_url(); ?>',types,'/delete/',id; } } </script> So here is my question: I would like the $type to be replaced by a paramenter (like client, article, post .. ) that I'll pass to the function. And i would like to get the $client-id parameter as well. I'm bad in javascript and as you already have guess, It is obviously not working at all.

Is dynamic_cast what I should use here? Thanks in advance EDIT: I know above code is much like plain C and surely sucks from the C++ point of view but is just I have the following situation and I was trying something before really implementing it: I have two arrays of length n but both arrays will never have an object at the same index. Hence, or I have array1[i]!=NULL or array2[i]!=NULL. This is obviously a waste of memory so I thought everything would be solved if I could have both kind of objects in a single array of length n. I am looking something like Cocoa's (Objective-C) NSArray where you don't care about the type of the object to be put in. Not knowing the type of the object is not a problem since you can use other method to get the class of a certain later. Is there something like it in c++ (preferably not third party C++ libraries) ? Thanks in advance ;)

  • Python "callable" attribute (pseudo-property)

    - by mgilson
    In python, I can alter the state of an instance by directly assigning to attributes, or by making method calls which alter the state of the attributes: foo.thing = 'baz' or: foo.thing('baz') Is there a nice way to create a class which would accept both of the above forms which scales to large numbers of attributes that behave this way? (Shortly, I'll show an example of an implementation that I don't particularly like.) If you're thinking that this is a stupid API, let me know, but perhaps a more concrete example is in order. Say I have a Document class. Document could have an attribute title. However, title may want to have some state as well (font,fontsize,justification,...), but the average user might be happy enough just setting the title to a string and being done with it ... One way to accomplish this would be to: class Title(object): def __init__(self,text,font='times',size=12): self.text = text self.font = font self.size = size def __call__(self,*text,**kwargs): if(text): self.text = text[0] for k,v in kwargs.items(): setattr(self,k,v) def __str__(self): return '<title font={font}, size={size}>{text}</title>'.format(text=self.text,size=self.size,font=self.font) class Document(object): _special_attr = set(['title']) def __setattr__(self,k,v): if k in self._special_attr and hasattr(self,k): getattr(self,k)(v) else: object.__setattr__(self,k,v) def __init__(self,text="",title=""): self.title = Title(title) self.text = text def __str__(self): return str(self.title)+'<body>'+self.text+'</body>' Now I can use this as follows: doc = Document() doc.title = "Hello World" print (str(doc)) doc.title("Goodbye World",font="Helvetica") print (str(doc)) This implementation seems a little messy though (with __special_attr). Maybe that's because this is a messed up API. I'm not sure. Is there a better way to do this? Or did I leave the beaten path a little too far on this one? I realize I could use @property for this as well, but that wouldn't scale well at all if I had more than just one attribute which is to behave this way -- I'd need to write a getter and setter for each, yuck.
