  • NSTableView not refreshing when calling method from different class

    - by Matt S.
    I have a table view that gets refreshed two different ways. One is through a button and the other is when I call my refresh method, which is the same method that I use for the button, but for some reason, when I hit the button it works, but when I call it through a different class it doesn't. Here's the code that I use to refresh the tableview: Msqv *qv = [Msqv new]; [qv refresh:self]; //refresh is an IBAction that is used by the button

  • interface abstract in php real world scenario

    - by jason
    The goal is to learn whether to use abstract or interface or both... I'm designing a program which allows a user to de-duplicate all images but in the process rather then I just build classes I'd like to build a set of libraries that will allow me to re-use the code for other possible future purposes. In doing so I would like to learn interface vs abstract and was hoping someone could give me input into using either. Here is what the current program will do: recursive scan directory for all files determine file type is image type compare md5 checksum against all other files found and only keep the ones which are not duplicates Store total duplicates found at the end and display size taken up Copy files that are not duplicates into folder by date example Year, Month folder with filename is file creation date. While I could just create a bunch of classes I'd like to start learning more on interfaces and abstraction in php. So if I take the scan directory class as the first example I have several methods... ScanForFiles($path) FindMD5Checksum() FindAllImageTypes() getFileList() The scanForFiles could be public to allow anyone to access it and it stores in an object the entire directory list of files found and many details about them. example extension, size, filename, path, etc... The FindMD5Checksum runs against the fileList object created from scanForFiles and adds the md5 if needed. The FindAllImageTypes runs against the fileList object as well and adds if they are image types. The findmd5checksum and findallimagetypes are optionally run methods because the user might not intend to run these all the time or at all. The getFileList returns the fileList object itself. While I have a working copy I've revamped it a few times trying to figure out whether I need to go with an interface or abstract or both. I'd like to know how an expert OO developer would design it and why?

  • load page with inactive scrollbar

    - by atwellpub
    I have a page that scrolls through images, some taller than the others. When a tall image loads it auto-creates a scrollbar in the browser window, causing a width jerk. Is there a way to load a scroll bar regardless of if it is needed, and when a tall image apears it activates itself accordingly, then deactivates its self accordingly when the image changes to a shorter image? Thank you!

    - by Adam
    Does anyone know of a good resource on the Audible Audio (.aa) file spec? I'm trying to write a program that can use them, if no one knows of a resource, any tips on reverse engineering the spec my self?

  • closure not working

    - by dorelal
    var Dog = function() { var _instance = 'hello world'; return function() { console.log(this._instance); } } (); //note that it is self invoking function var l = new Dog(); //#> undefined In the above case I was expecting output of 'hello world'. Why this._instance is not accessing the the varible which should be accessible by virtue of closure. I tested this in FF and am getting undefined.

  • Javascript Function Definitions

    - by Pierreten
    I was wondering why the Vector variable defined within this self executing javascript function doesn't require a var before it? Is this just some other type of syntax for creating a named function? Does this make it so we can't pass Vector as an argument to other functions? (function() { Vector = function(x, y) { this.x = x; this.y = y; return this; }; //...snip })()

  • Is Maven really flexible?

    - by Dima
    I understand how Maven works with .java files in src/java/main. But may it be used for a more general case? Let us put it more abstract: Suppose I already have some a.exe that read some (not necessarily only .java) sources from directories A1, A2, A3 and puts some files (maybe some are generated .java) to directories B1, B2. I also have some b.exe that currently reads files from B1, B2, B3 and generates something else. Some more similar steps. (A real life problem stands behind). I would like to right POM.xml file so that maven will do this work. Is that possible? I assume that a.exe and b.exe should be warped as maven plugings. Next, in Maven docs I see : <build> <sourceDirectory>${basedir}/src/main/java</sourceDirectory> <scriptSourceDirectory>${basedir}/src/main/scripts</scriptSourceDirectory> <testSourceDirectory>${basedir}/src/test/java</testSourceDirectory> <outputDirectory>${basedir}/target/classes</outputDirectory> <testOutputDirectory>${basedir}/target/test-classes</testOutputDirectory> ... </build> What bothers me is that "sourceDirectory" looks by itself as a hard coded name. Will Maven accept A1 and A2 tags instead?

  • CodeIgniter and Your Own Scripts

    - by Abs
    Hello all, I have found a class I would like to use to get bookmarks from a users delicious account. Here is how it is used. The problem I am having is, should I be turning this into a Codeigniter library? Can I not use it on its own as this is self contained? I am guessing I am asking for the best practice here. Thanks all for any help

  • How to override 'where' in rails 3

    - by Zakwan Alhajjar
    I have upgraded my application from rails 2.3.8 to 3.0.3 . But I'm facing a problem. I was using 'find' but the overriding doesn't work in rails 3: # override activerecord's find to allow us to find by name or id transparently def self.find(*args) if args.is_a?(Array) and args.first.is_a?(String) and (args.first.index(/[a-zA-Z\-_]+/) or args.first.to_i.eql?(0) ) find_by_login_slug(args) else super end end I'm wondering if there is a way to make this work in rails 3 or even by using where instead. thanks
