  • DIV is picking max-width value as width value for DIV.

    - by Lokesh
    I am facing a problem after applying max-width hack for IE7. In mozilla, width of the div is flexible and adjustable as per the image width in the div. But in IE7 it is taking the max-width as width of DIV. Below is my HTML code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <link rel="stylesheet" type="text/css" media="all" href="style/food.css" /> <!--[if IE 7]> <link rel="stylesheet" type="text/css" media="screen" href="style/ie7.css" /> <![endif]--> </head> <body> <div class="main_content_inner_ko"> <div class="product_item"> <img src="images/product_icons/BigNTasty.png" alt="Big N&rsquo;

  • In Ruby are there any related applications of the syntax: class << self ... end

    - by pez_dispenser
    class << self attr_accessor :n, :totalX, :totalY end The syntax above is used for defining class instance variables. But when I think about what syntax implies, it doesn't make any sense to me, so I'm wondering if this type of syntax is used for any other types of definitions. My point of confusion here is this: class << self The append operator normally means "add what's on the right to the object on the left". But in the context of this block, how does that add up to "put the contents of this block into the definition of the class instance rather than the instance"? For the same reason I'm confused as to why in one context class << self can define class instance variables while in another it seems to create class variables such as here: class Point # Instance methods go here class << self # Class methods go here end end

  • UML class diagram - can aggregated object be part of two aggregated classes?

    - by user970696
    Some sources say that aggregation means that the class owns the object and shares reference. Lets assume an example where a company class holds a list of cars but departments of that company has list of cars used by them. class Department { list<Car> listOfCars; } class Company { list<Car> listOfCars; //initialization of the list } So in UML class diagram, I would do it like this. But I assume this is not allowed because it would imply that both company and department own the objects.. [COMPANY]<>------[CAR] [DEPARTMENT]<>---| //imagine this goes up to the car class

  • Base class -> Derived class and vice-versa conversions in C++

    - by Ivan Nikolaev
    Hi! I have the following example code: #include <iostream> #include <string> using namespace std; class Event { public: string type; string source; }; class KeyEvent : public Event { public: string key; string modifier; }; class MouseEvent : public Event { public: string button; int x; int y; }; void handleEvent(KeyEvent e) { if(e.key == "ENTER") cout << "Hello world! The Enter key was pressed ;)" << endl; } Event generateEvent() { KeyEvent e; e.type = "KEYBOARD_EVENT"; e.source = "Keyboard0"; e.key = "SPACEBAR"; e.modifier = "none"; return e; } int main() { KeyEvent e = generateEvent(); return 0; } I can't compile it, G++ throws an error of kind: main.cpp: In function 'int main()': main.cpp:47:29: error: conversion from 'Event' to non-scalar type 'KeyEvent' requested I know that the error is obvious for C++ guru's, but I can't understand why I can't do the conversion from base class object to derived one. Can someone suggest me the solution of the problem that I have? Thx in advice

  • 'abstract class' versus 'normal class' for a reusable library

    - by Greg
    I'm developing a reusable library and have been creating abstract classes, so the client can then extend from these. QUESTION: Is there any reason in fact I should use an abstract class here as opposed to just a normal class? Note - Have already decided I do not want to use interfaces as I want to include actual default methods in my library so the client using it doesn't have to write the code.

  • Plane projection and scale causing bluring in silverlight

    - by Andy
    Ok, So I've tried to make an application which relies on images being scaled by an individual factor. These images are then able to be turned over, but the use of an animation working on the ProjectionPlane rotation. The problem comes around when an image is both scaled and rotated. For some reason it starts bluring, where a non scaled image doesn't blur. Also, if you look at the example image below (top is scaled and rotated, bottom is rotated) the projection of the top one doesn't even seem right. Its too horizontal. This this the code for the test app: <UserControl x:Class="SilverlightApplication1.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="400" Height="300"> <Canvas x:Name="LayoutRoot" Background="White"> <Border Canvas.Top="25" Canvas.Left="50"> <Border.RenderTransform> <TransformGroup> <ScaleTransform ScaleX="3" ScaleY="3" /> </TransformGroup> </Border.RenderTransform> <Border.Projection> <PlaneProjection RotationY="45"/> </Border.Projection> <Image Source="bw-test-pattern.jpg" Width="50" Height="40"/> </Border> <Border Canvas.Top="150" Canvas.Left="50"> <Border.RenderTransform> <TransformGroup> <ScaleTransform ScaleX="1" ScaleY="1" /> </TransformGroup> </Border.RenderTransform> <Border.Projection> <PlaneProjection RotationY="45"/> </Border.Projection> <Image Source="bw-test-pattern.jpg" Width="150" Height="120"/> </Border> </Canvas> </UserControl> So if anyone could possible shed any light on why this may be happening, I'd very much appreciate it. Suggestions also welcome! :)

  • Isometric projection bad coordonate

    - by Christophe Debove
    I have a 2D map, for each element I apply this isometric projection to place my Sprite //Element e; float[] f= projection(e.getX(), e.getY() ,z); // x and y represent Sprite Coordonate (tile_width and height depend of my // camera size and the number of elements in x and in y float x = f[0]*tile_width; float y = f[1]*tile_height; public float[] projection(float x, float y, float z) { return new float[]{ (( x )-(y) ) , ((x/2) + (y/2) - z )}; } the sprite for one element : The result of my projection : The problem is I need to add an offset of tile_height/2 to the y and tile_width/2 to the x to have something like this (in the red rectangle I drawed with paint what I want) : Where did I make wrong? (I found the projection method in How should I sort images in an isometric game so that they appear in the correct order? )

  • Get subclass type from projection with NHibernate

    - by TigerShark
    Hi I am trying to do a projection on a type called Log. Log references a superclass called Company. Each company type is mapped with table per subclass. Is it possible for me to get the type of Company when I do a projection on Log? I currently have an Enum property (which is not mapped) on each subclass, so I can perform switches on Company types, but since it is not mapped to anything, I can't do a projection on it. I have tried Projections.Property("log.Company.class") but that does not work :( PS: I couldn't find a lot of appropriate tags for this question. If anyone have an idea for more specific tags, please tell me.

  • Abstract class + Inheritance vs Interface

    - by RealityDysfunction
    Hello fellow programmers, I am reading a book on C# and the author is comparing Abstract classes and Interfaces. He claims that if you have the following "abstract class:" abstract class CloneableType { public abstract object Clone(); } Then you cannot do this: public class MiniVan : Car, CloneableType {} This, I understand. However he claims that because of this inability to do multiple inheritance that you should use an interface for CloneableType, like so: public interface ICloneable { object Clone(); } My question is, isn't this somewhat misleading, because you can create an abstract class which is "above" class Car with the method Clone, then have Car inherit that class and then Minivan will inherit Car with all these methods, CloneAble class - Car class - Minivan Class. What do you think? Thanks.

  • Why should I declare a class as an abstract class?

    - by Pied Piper
    I know the syntax, rules applied to abstract class and I want know usage of an abstract class Abstract class can not be instantiated directly but can be extended by other class What is the advantage of doing so? How it is different from an Interface? I know that one class can implement multiple interfaces but can only extend one abstract class. Is that only difference between an interface and an abstract class? I am aware about usage of an Interface. I have learned that from Event delegation model of AWT in Java. In which situations I should declare class as an abstract class? What is benefits of that?

  • Python: query a class's parent-class after multiple derivations ("super()" does not work)

    - by henry
    Hi, I have built a class-system that uses multiple derivations of a baseclass (object-class1-class2-class3): class class1(object): def __init__(self): print "class1.__init__()" object.__init__(self) class class2(class1): def __init__(self): print "class2.__init__()" class1.__init__(self) class class3(class2): def __init__(self): print "class3.__init__()" class2.__init__(self) x = class3() It works as expected and prints: class3.__init__() class2.__init__() class1.__init__() Now I would like to replace the 3 lines object.__init__(self) ... class1.__init__(self) ... class2.__init__(self) with something like this: currentParentClass().__init__() ... currentParentClass().__init__() ... currentParentClass().__init__() So basically, i want to create a class-system where i don't have to type "classXYZ.doSomething()". As mentioned above, I want to get the "current class's parent-class". Replacing the three lines with: super(type(self), self).__init__() does NOT work (it always returns the parent-class of the current instance - class2) and will result in an endless loop printing: class3.__init__() class2.__init__() class2.__init__() class2.__init__() class2.__init__() ... So is there a function that can give me the current class's parent-class? Thank you for your help! Henry -------------------- Edit: @Lennart ok maybe i got you wrong but at the moment i think i didn't describe the problem clearly enough.So this example might explain it better: lets create another child-class class class4(class3): pass now what happens if we derive an instance from class4? y = class4() i think it clearly executes: super(class3, self).__init__() which we can translate to this: class2.__init__(y) this is definitly not the goal(that would be class3.__init__(y)) Now making lots of parent-class-function-calls - i do not want to re-implement all of my functions with different base-class-names in my super()-calls.

  • Advantages of Singleton Class over Static Class?

    Point 1)Singleton We can get the object of singleton and then pass to other methods.Static Class We can not pass static class to other methods as we pass objectsPoint 2) Singleton In future, it is easy to change the logic of of creating objects to some pooling mechanism. Static Class Very difficult to implement some pooling logic in case of static class. We would need to make that class as non-static and then make all the methods non-static methods, So entire your code needs to be changed.Point3:) Singleton Can Singletone class be inherited to subclass? Singleton class does not say any restriction of Inheritence. So we should be able to do this as long as subclass is also inheritence.There's nothing fundamentally wrong with subclassing a class that is intended to be a singleton. There are many reasons you might want to do it. and there are many ways to accomplish it. It depends on language you use.Static Class We can not inherit Static class to another Static class in C#. Think about it this way: you access static members via type name, like this: MyStaticType.MyStaticMember(); Were you to inherit from that class, you would have to access it via the new type name: MyNewType.MyStaticMember(); Thus, the new item bears no relationships to the original when used in code. There would be no way to take advantage of any inheritance relationship for things like polymorphism. span.fullpost {display:none;}

  • Manager/Container class vs static class methods

    - by Ben
    Suppose I a have a Widget class that is part of a framework used independently by many applications. I create Widget instances in many situations and their lifetimes vary. In addition to Widget's instance specified methods, I would like to be able to perform the follow class wide operations: Find a single Widget instance based on a unique id Iterate over the list of all Widgets Remove a widget from the set of all widgets In order support these operations, I have been considering two approaches: Container class - Create some container or manager class, WidgetContainer, which holds a list of all Widget instances, support iteration and provides methods for Widget addition, removal and lookup. For example in C#: public class WidgetContainer : IEnumerable<Widget { public void AddWidget(Widget); public Widget GetWidget(WidgetId id); public void RemoveWidget(WidgetId id); } Static class methods - Add static class methods to Widget. For example: public class Widget { public Widget(WidgetId id); public static Widget GetWidget(WidgetId id); public static void RemoveWidget(WidgetId id); public static IEnumerable<Widget AllWidgets(); } Using a container class has the added problem of how to access the container class. Make it a singleton?..yuck! Create some World object that provides access to all such container classes? I have seen many frameworks that use the container class approach, so what is the general consensus?

  • Using a database class in my user class

    - by Josh
    In my project I have a database class that I use to handle all the MySQL stuff. It connects to a database, runs queries, catches errors and closes the connection. Now I need to create a members area on my site, and I was going to build a users class that would handle registration, logging in, password/username changes/resets and logging out. In this users class I need to use MySQL for obvious reasons... which is what my database class was made for. But I'm confused as to how I would use my database class in my users class. Would I want to create a new database object for my user class and then have it close whenever a method in that class is finished? Or do I somehow make a 'global' database class that can be used throughout my entire script (if this is the case I need help with that, no idea what to do there.) Thanks for any feedback you can give me.

  • Linking a template class using another template class (error LNK2001)

    - by Luís Guilherme
    I implemented the "Strategy" design pattern using an Abstract template class, and two subclasses. Goes like this: template <class T> class Neighbourhood { public: virtual void alter(std::vector<T>& array, int i1, int i2) = 0; }; and template <class T> class Swap : public Neighbourhood<T> { public: virtual void alter(std::vector<T>& array, int i1, int i2); }; There's another subclass, just like this one, and alter is implemented in the cpp file. Ok, fine! Now I declare another method, in another class (including neighbourhood header file, of course), like this: void lSearch(/*parameters*/, Neighbourhood<LotSolutionInformation> nhood); It compiles fine and cleanly. When starting to link, I get the following error: 1>SolverFV.obj : error LNK2001: unresolved external symbol "public: virtual void __thiscall lsc::Neighbourhood<class LotSolutionInformation>::alter(class std::vector<class LotSolutionInformation,class std::allocator<class LotSolutionInformation> > &,int,int)" (?alter@?$Neighbourhood@VLotSolutionInformation@@@lsc@@UAEXAAV?$vector@VLotSolutionInformation@@V?$allocator@VLotSolutionInformation@@@std@@@std@@HH@Z)

  • Building a database class in PHP

    - by Sprottenwels
    I wonder if I should write a database class for my application, and if so, how to accomplish it? Over there on SO, a guy mentioned it should be written as an abstract class. However, I can't understand why this would be a benefit. Do I understand correctly, that if I would write an abstract class, every other class that methods will need a database connection, could simply extend this abstract class and have it's own database object? If so, how is this different from a "normal" class where I could instantiate an database object? Another method would be to completely forget about my own class and to instantiate a mysqli object on demand. What do you recommend?
