  • GWT: how to have different styles for splitters in different SplitLayoutPanels?

    - by user26270
    I know you can change the styles of the splitters with the defaults styles listed in the docs: .gwt-SplitLayoutPanel .gwt-SplitLayoutPanel-HDragger { horizontal dragger } .gwt-SplitLayoutPanel .gwt-SplitLayoutPanel-VDragger { vertical dragger } and we've done that in earlier development. However, now I'm developing new stuff and would like to use a different style for the splitters in a new SplitLayoutPanel. Unfortunately, we haven't or can't split the app into different modules, which might make this easier. I tried creating a new style and applying it to my new SplitLayoutPanel, but it didn't appear to have any effect on the splitters. I thought there might be a method to get a handle on the splitters in order to apply the new style to only them, but I didn't find any such method.

  • C++ template specialization

    - by user231536
    I have a class template <typename T> class C { static const int K=1; static ostream& print(ostream& os, const T& t) { return os << t;} }; I would like to specialize C for int. //specialization for int template <> C<int>{ static const int K=2; } I want the default print method that works for int to remain and just change the constant. For some specializations, I want to keep K=1 and change the print method because there is no << operator. How do I do this?

  • Symfony models with foreign keys

    - by Daniel Hertz
    So I have 2 models. Users and Groups. Each group has a user as the creator and a group has many users. The FK of these tables are set up correctly, but I was wondering if there was an easier way to get all related FK objects from other objects. For example, with a group object, is there a built in method to get the user object of the creator? Or for a user, is there a built in method to get all group object that he belongs to? I couldn't find out how to do this with the documentation on the symfony page. From what I see I feel like I need to create methods and use doctrine to access the appropriate tables using the current objects id and so on. Thanks!

  • Ruby on Rails Problem PotionStore

    - by David Schiefer
    Hello, I am trying to install the PotionStore on my Mac OS X 10.6 server with Ruby on Rails 3 installed. Upon launching the server on port 3000 and pointing safari to this address, I get this: NameError in Store/orderController#index uninitialized constant ActiveRecord::ConnectionAdapters::PostgreSQLAdapter::PGconn What does this mean? I'm not too advanced with Ruby on Rails, so this throws me a bit.

    - by mobby1982
    i am a newbie . i have a question regarding struts 2 framework and tomcat . i know that each request has it own thread , but my question is are the global variables defined in struts action shared amongst requests. for ex: if i have a global variable named say int pageNo; and i am using in say method called paginationAll() can i use the same variable (pageNo) for another method called say paginatonMaterialAll() in the same action or does each thread has its own set of variables even though globally defined?

  • [Scala] Applying overloaded, typed methods on a collection

    - by stephanos
    I'm quite new to Scala and struggling with the following: I have database objects (type of BaseDoc) and value objects (type of BaseVO). Now there are multiple convert methods (all called 'convert') that take an instance of an object and convert it to the other type accordingly - like this: def convert(doc: ClickDoc): ClickVO = ... def convert(doc: PointDoc): PointVO = ... def convert(doc: WindowDoc): WindowVO = ... Now I sometimes need to convert a list of objects. How would I do this - I tried: def convert[D <: BaseDoc, V <: BaseVO](docs: List[D]):List[V] = docs match { case List() => List() case xs => xs.map(doc => convert(doc)) } Which results in 'overloaded method value convert with alternatives ...'. I tried to add manifest information to it, but couldn't make it work. I couldn't even create one method for each because it'd say that they have the same parameter type after type erasure (List). Ideas welcome!

  • What Are Collections Implemented As In VB6?

    - by Tom Tresansky
    So a collection in VB6 keeps track of a key for each object, and you can look up the object by its key. Does that mean collections are implemented as some sort of hashtable under the hood? I realize you can have multiple items with the same key in a collection, hence the SOME SORT. Anybody know what type data structure a VB6 collection is supposed to represent?

  • How to insert into data base using multi threading programming [closed]

    - by user1196650
    I am having a method and that method needs to do the following thing: It has to insert records into a database. No insert is done for the same table again. All inserts are into different tables. I need a multi threading logic which inserts the details into db using different threads. I am using oracle db and driver configuration and remaining stuff are perfect. Please help me with an efficient answer. Can anyone could provide me with a skeleton logic of the program.

  • Changing XML Namespace with Scala

    - by toddk
    I am using scala to load a XML file from file via the scala.xml.XML.loadFile() method. The documents I'm working with have namespaces already defined and I wish to change the namespace to something else using scala. For example, a document has a xmlns of "http://foo.com/a" with a prefix of "a" - I would like to change the namespace and prefix for the document to "http://foo.com/b" and "b" respectively. Seems easy and I feel like I'm missing something obvious here. I do not have a problem getting the namespace from the return Elem from the referenced loadFile() method.

  • best way to store list of websites on iphone app

    - by Jonathan
    By best I mean most efficient. So don't go on about subjectiveness. I have a list of websites and I want to store the list on the iphone locally, there must be an URL, title and a small image (like 32x32 max image size). I don't think I should be using CoreData for this. Should I be using a plist?

  • What Parallel computing APIs take good use of sockets?

    - by Ole Jak
    What Parallel computing APIs take good use of sockets? So my programm uses soskets, what Parallel computing APIs I can use that would help me but will not obligate me to go from sockets to anything else... I mean when we are on claster with some special, not socket infrastructure sistem that API emulates something like socket but uses that infrustructure (so programm peforms much faster then on sockets, but keeps having nice soskets API)

  • Extendable accessing of sqlite database on android platform

    - by mscriven
    Hi, I am fairly new to the android sdk and databases and have been searching for an answer to this quite some time. I am trying to build an app which has multiple tables within a database. e.g. one for weapons, armours etc. However, my DatabaseManager class which handles all of my table creating, DatabaseHelper inner class and populating of data is creating for an extremely large class requiring high maintenance. Every time I would like to add or remove a table column I need to change quite a few areas of code, - Every reference to the addition of a row in that table with data - The method that the above calls - The method returning all of the database rows - The code in the helper class creating the table - Any specific update methods My question is this: Surely there must be some better way of coding this system, maybe using a database isn't the best way to go, or am i just not used to such large classes having only learned java at university and my largest class consisting of a mere 400-600 lines of code. Thanks for any help!

  • Play a Sound with Python

    - by Claudiu
    What's the easiest way to play a sound file (.wav) in Python? By easiest I mean both most platform independent and requiring the least dependencies. pygame is certainly an option, but it seems overkill for just sound.

  • How to do something after effect animation ends in Flex?

    - by Chobicus
    I'm a beginner in Flex so there must be more elegant way of doing this. //move effect private var m:Move = new Move(); //this function creates labels with some text and starts move effect on them public function moveText(i:int):void { var myLabel:Label = new Label(); myLabel.text = "some text"; m.target = myLabel; ... m.play(); } Method moveText is called in a loop so I guess that labels don't get "garbage collected". What I want to do is to remove Labels created in moveText method after play animation ends. Another way of doing this is maybe creating some kind of "pool" of labels which I would use to move arround text. I don't know how would I return labels in to "pool". The question is how to do something after effect animation ends?
