• ActionScript 3 Context Menu Per Sprite?

  - by TheDarkIn1978

  is it not possible to have different context menus for different sprites on the stage? i've tried adding a custom context menu to a sprite but it's applied to the entire stage: mySprite.contextMenu = myMenu; then after reading the documentation where it states: You can attach a ContextMenu object to a specific button, movie clip, or text field object, or to an entire movie level. You use the menu property of the Button, MovieClip, or TextField class to do this. ok, so i though i had to write it like: mySprite.menu.contextMenu = myMenu; only to be greeted with a nice migration issue stating that menu is legacy code and to use contextMenu instead. ??? um, thanks for the headsup, documentation. this process would be entirely much more easier if i could extend the ContextMenu, but for some reason it's marked as "final" and can't be extended... i'm sure adobe's reasons for finalizing the context menu class are as good as their reasons for including misleading documentation. thoughts?

• How do I (or should I?) access the service layer from a SiteMesh template (views/layouts/main.gsp) in Grails?

  - by knorv

  I need to create a toplist in the page footer on a site that I'm building. The footer is created in the default SiteMesh layout template (views/layouts/main.gsp). In order to create the toplist access to the database is needed, so I've encapsulated all logic needed for the toplist creation in a service class (services/FooService). Please note that while services are usually accessed from the controller layer, in this case the default layout template (views/layouts/main.gsp) is not generated from a controller. Can the layout view (views/layouts/main.gsp) access a service class? How? Is this the correct design decision? If not, what is a better encapsulation and how do I interact with said encapsulation from the layout view (views/layouts/main.gsp)?

• How to add a custom loglevel to Python's logging facility

  - by tuergeist

  Hi, I'd like to have loglevel TRACE (5) for my application as I don't think that debug() is enought. Additionally log(5, msg) isn't what I want. The question is, how can I add a custom log level to a Python logger? Actually I've a mylogger.py with the following content: import logging @property def log(obj): myLogger = logging.getLogger(obj.__class__.__name__) return myLogger In my code I use it in the following way: class ExampleClass(object): from mylogger import log def __init__(self): '''The constructor with the logger''' self.log.debug("Init runs") Now I'd like to call self.log.trace("foo bar") Thanks in advance for your help.

• KeyNotFound Exception in Dictionary(of T)

  - by C Patton

  I'm about ready to bang my head against the wall I have a class called Map which has a dictionary called tiles. class Map { public Dictionary<Location, Tile> tiles = new Dictionary<Location, Tile>(); public Size mapSize; public Map(Size size) { this.mapSize = size; } //etc... I fill this dictionary temporarily to test some things.. public void FillTemp(Dictionary<int, Item> itemInfo) { Random r = new Random(); for(int i =0; i < mapSize.Width; i++) { for(int j=0; j<mapSize.Height; j++) { Location temp = new Location(i, j, 0); int rint = r.Next(0, (itemInfo.Count - 1)); Tile t = new Tile(new Item(rint, rint)); tiles[temp] = t; } } } and in my main program code Map m = new Map(10, 10); m.FillTemp(iInfo); Tile t = m.GetTile(new Location(2, 2, 0)); //The problem line now, if I add a breakpoint in my code, I can clearly see that my instance (m) of the map class is filled with pairs via the function above, but when I try to access a value with the GetTile function: public Tile GetTile(Location location) { if(this.tiles.ContainsKey(location)) { return this.tiles[location]; } else { return null; } } it ALWAYS returns null. Again, if I view inside the Map object and find the Location key where x=2,y=2,z=0 , I clearly see the value being a Tile that FillTemp generated.. Why is it doing this? I've had no problems with a Dictionary such as this so far. I have no idea why it's returning null. and again, when debugging, I can CLEARLY see that the Map instance contains the Location key it says it does not... very frustrating. Any clues? Need any more info? Help would be greatly appreciated :)

• OS monitoring using JAVA

  - by Puneri

  I'm planning to implement a framework for monitoring OS level resources: process network stats cpu info etc using JAVA. I see there is SIGAR API by Spring, which is implemented in native language and JAVA API being provided on top. But I will prefer not to have native stuff in my framework, rather for each OS will write a Java Class which will fetch required OS info by running system commands via JAVA Runtime. So I would like to have inputs/suggestions that one may have seen of not doing this in JAVA and use native app/api/jni. Any example will help for sure. I agree each OS has different commands to get these stats, but will prefer to have a Java Class per OS than have/load native code.

• Instantiation vs. Typed reference

  - by Farstucker

  Just when I think Im starting to understand the basics, I find something that brings me right back to reality. In this case, typed reference. I found an example similar to this: class Worker { Boss boss; public void Advise(Boss pBoss) { this.boss = pBoss; } How can you reference methods within the Boss class if its not static and not instantiated? I guess my real question is whats the difference between: Boss boss; and Boss boss = new Boss(); Thank you, FS

• [CSS] style input tag

  - by nosferat

  Hi! ASP.Net has a tag called CheckboxList. The output of this tag looks like this: <table class="checkbox"> <tbody> <tr> <td> <input id="/*longdynamicstring1*/" type="checkbox" name="/*longdynamicstring2*/" /> <label for="/*longdynamicstring1*/">Label Text</label> </td> </tr> </tbody> </table> I want to position the label and the input but I cannot find out how. Tried the following: .checkbox input{ padding-right: 5px; } and .checkbox input[type='checkbox'] { padding-right: 5px; } but neither of them had any effect. Because it's ASP I cannot set a class for the input elements and I cannot reference the id because it's dynamic.

  - by Minelava

  I need help because I want to create a gameover screen that display score. However, there's an error that prevent me from transferring the score from theplayclass.as to thegameoverclass.as.

• Change right-click context menu options in VS2008

  - by Mark Ursino

  When I right-click in my class library, I get some quick options to create things, like an Item from the popup list (New Item...), a User Control, etc. E.g. Now in my web app project, I'd like to be able to get the User Control listed in the right-click menu just like Component and Class, so I don't have to click New Item... then choose it from there. Is there a way to do this in the configuration? I can't seem to figure it out in VS.

• Globals across modules

  - by Coder1

  Wow, this seems so basic, but I can't get it to work. All I need to do is store a global dict which can be accessed and modified from other modules & threads. What's the "best practices" way of achieving this? test.py import testmodule class MyClassA(): def __init__(self, id): self.id = id if __name__ == '__main__': global classa_dict classa_dict = {} classa_dict[1] = MyClassA(1) classa_dict[2] = MyClassA(2) testing = testmodule.TestModule() testmodule.py class TestModule(): def __init__(self): global classa_dict print classa_dict[2] output $ python test.py Traceback (most recent call last): File "test.py", line 13, in <module> testing = testmodule.TestModule() File "/path/to/project/testmodule.py", line 4, in __init__ print classa_dict[2] NameError: global name 'classa_dict' is not defined

• Java: how to represent graphs?

  - by Rosarch

  I'm implementing some algorithms to teach myself about graphs and how to work with them. What would you recommend is the best way to do that in Java? I was thinking something like this: public class Vertex { private ArrayList<Vertex> outnodes; //Adjacency list. if I wanted to support edge weight, this would be a hash map. //methods to manipulate outnodes } public class Graph { private ArrayList<Vertex> nodes; //algorithms on graphs } But I basically just made this up. Is there a better way? Also, I want it to be able to support variations on vanilla graphs like digraphs, weighted edges, multigraphs, etc.

• How to map it? HasOne x References

  - by Felipe

  Hi everyones, I need to make a mapping One by One, and I have some doubts. I have this classes: public class DocumentType { public virtual int Id { get; set; } /* othes properties for documenttype */ public virtual DocumentConfiguration Configuration { get; set; } public DocumentType () { } } public class DocumentConfiguration { public virtual int Id { get; set; } /* some other properties for configuration */ public virtual DocumentType Type { get; set; } public DocumentConfiguration () { } } A DocumentType object has only one DocumentConfiguration, but it is not a inherits, it's only one by one and unique, to separate properties. How should be my mappings in this case ? Should I use References or HasOne ? Someone could give an example ? When I load a DocumentType object I'd like to auto load the property Configuration (in documentType). Thanks a lot guys! Cheers

• Validates presence of each other in two associated models

  - by Sergey Alekseev

  I have the following two models: class Parent < ActiveRecord::Base has_one :child, dependent: :destroy validates :child, presence: true end class Child < ActiveRecord::Base belongs_to :parent validates :parent, presence: true end I want to create Parent object. If I do the following: Parent.create! or Factory(:parent) Exception raises: ActiveRecord::RecordInvalid: Validation failed: Child can't be blank But I can't create Child object without Parent object for the same reason - I need to create Parent object first in order to pass presence validation. As it appears I have some kind of infinite recursion here. How to solve it?

• QMap inheritance with QMapIterator

  Hi, I made a personnal class which inherits QMap: class CfgMgr : public QMap<QString, CfgSet*> {...} I'm trying to iterate over all its elements like that: CfgMgr* m_pDefaults = new CfgMgr; // .../... QMapIterator<QString, CfgSet*> ics(*m_pDefaults); while (ics.hasNext()) { // doing my stuff } And I get the compile error: Can't convert parameter 1 from 'CfgMgr' to 'const QMap< Key,T &' with [ Key=QString, T=CfgSet * ] I tried with a dynamic_cast: QMapIterator<QString, CfgSet*> ics( *dynamic_cast< QMap<QString,CfgSet*>* >(m_pDefaults) ); it compiles, but always returns NULL. What's wrong? How can I solve this?

• Interface with generic parameters- can't get it to compile

  - by user997112

  I have an interface like so: public interface MyInterface<E extends Something1> { public void meth1(MyClass1<E> x); } and I have a subclass whose superclass implements the above interface: public class MyClass2<E extends Something1> extends Superclass{ public MyClass2(){ } public void meth1(MyClass1 x) { // TODO Auto-generated method stub } } superclass: public abstract class Superclass<E extends Something1> implements MyInterface{ MyClass1<E> x; protected E y; public Superclass(){ } } the problem is that the parameter for meth1() is supposed to be generic. If I do MyClass1 it doesn't like it and the only way I can get it to compile is by leaving out generic parameters- which feels wrong. What's going wrong?

• Suggested C++ books?

  - by Josh Bradley

  Ok, I've had one semester of C++ and will be taking a second semester in it after I have taken a Data Structure class this fall. In the first class, we dealt mainly with C++ syntax and the textbook we used was ok, but now I'm wanting to go ahead and purchase a great C++ book that encompasses a lot of the programming concepts used today. I'm learning Objective-C on my own and was able to get through the whole object-oriented stuff pretty easily, along with other things like pointers, inheritance, delegation, etc. It doesn't have to exactly have EVERYTHING in it, but I do want to buy the book with the most information in it. Money is no problem. So my question is what book did you use or still use for C++? Is it a book that you can reference back to if you ever forget how to do something small, or would you have to go online and find the answer.

• C++ MFC add combo box string item from a widget ID

  - by OzBarry

  I've added a combo box in the gui editor in MSVC 2010 pro in my MFC project. I have a list of strings I am grabbing from an external source and want to add them to my combo box. I've searched for a while, and every post seems to suggest I need to use the CComboBox class, however, I have no idea how to get the class variable from the resource ID of the combobox element in the gui editor. In summary, how do I add a string to my combo box, either using a macro (like CB_ADDSTRING(RESOURCE_ID, "my string");) or using CComboBOx (something like CComboBox::GetObject(RESOURCE_ID)->AddString("blah");). I do not do much win32 api/mfc programming, and just started fiddling around with it.

• What is the pythonic way to add type information to an object's attributes?

  - by Tikitu

  I'm building classes where I know the types of the attributes, but Python of course doesn't. While it's un-pythonic to want to tell it, supposing I do want to, is there an idiomatic way to do so? Why: I'm reading in serialised data (without type information) involving objects-nested-inside-objects. It's easy to put it into nested dictionaries, but I want it in objects of my class-types, to get the right behaviours as well as the data. For instance: suppose my class Book has an attribute isbn which I will fill with an ISBNumber object. My serialised data gives me the isbn as a string; I would like to be able to look at Book and say "That field should be filled by ISBNumber(theString)." Bonus glee for me if the solution can be applied to classes I get from someone else without editing their code.

• JQuery Validation Plugin not working when used on page that includes another page via AJAX

  - by droidy

  We have a long page that contains a bunch of different form elements. One part of the form is called remotely via AJAX and is populated in an empty div. This is the part which JQuery Validation plugin is not working correctly on. We have class="required" on the elements on this page, but they do not show up as required. I'm guessing it's because the Validation plugin is looking for class="required" on our main page, and since the content from the AJAX page is put into the empty div behind the scenes, it's not detected the required fields. Any help is greatly appreciated.
