  • Why can I not access this class member in python?

    - by Peter Smit
    I have the following code class Transcription(object): WORD = 0 PHONE = 1 STATE = 2 def __init__(self): self.transcriptions = [] def align_transcription(self,model,target=Transcription.PHONE): pass The important part here is that I would like to have a class member as default value for a variable. This however gives the following error: NameError: name 'Transcription' is not defined Why is this not possible and what is the right (pythonic) way to do something like this.

  • In ADL_Display_ConnectedDisplays_Get() from ATI's ADL Library, the out parameter lpConnections is co

    - by animesh
    The API defined in the ADL SDK manual reads: int ADL_Display_ConnectedDisplays_Get(int iAdapterIndex, int* lpConnections) They say that lpConnections is the pointer to the bit field indicating whether the output connectors on the specified adapter have devices physically attached to them. This information is exactly what I want but nowhere in the documentation I could find any data on what the various bits in the lpConnections obtained might mean. I also tried going through the header files but found nothing relevant on this. I know this is very specific to but can anyone here answer?

  • Drawing with element array in OpenGL ES

    - by FatalMojo
    Hello! I am trying to use OpenGLES to draw a x by y matrix of squares about an arbitrary point. I have an array sideVertice[] that holds a series of vertex structs defined as such typedef struct { GLfloat x; GLfloat y; GLfloat z; } Vertex3D; and an element array defined as such GLubyte elementArray[]; my draw loop is as such glLoadIdentity(); glVertexPointer(3, GL_FLOAT, 0, cube.sideVertice); for (int i=0; i<((cube.cubeSize + 1)*(cube.cubeSize + 1)); i++) { for (int j=0; j<=3; j++) { elementArray[j] = j + i*4; glDrawElements(GL_TRIANGLE_STRIP, 4, GL_UNSIGNED_BYTE, elementArray); } } for (int i=0; i<=3; i++) elementArray[i] = i; However, the visual output is corrupted and I cannot figure out what the problem is. here is an output of the vertice held in the array: 2010-04-15 23:44:48.816 RubixGL[4203:20b] vertex[0][0] x:-26.000000 y:1.000000 2010-04-15 23:44:48.817 RubixGL[4203:20b] vertex[1][1] x:-26.000000 y:26.000000 2010-04-15 23:44:48.826 RubixGL[4203:20b] vertex[2][2] x:-1.000000 y:1.000000 2010-04-15 23:44:48.829 RubixGL[4203:20b] vertex[3][3] x:-1.000000 y:26.000000 2010-04-15 23:44:48.830 RubixGL[4203:20b] Next Face 2010-04-15 23:44:48.830 RubixGL[4203:20b] vertex[0][4] x:1.000000 y:1.000000 2010-04-15 23:44:48.832 RubixGL[4203:20b] vertex[1][5] x:1.000000 y:26.000000 2010-04-15 23:44:48.837 RubixGL[4203:20b] vertex[2][6] x:26.000000 y:1.000000 2010-04-15 23:44:48.838 RubixGL[4203:20b] vertex[3][7] x:26.000000 y:26.000000 2010-04-15 23:44:48.848 RubixGL[4203:20b] Next Face 2010-04-15 23:44:48.849 RubixGL[4203:20b] vertex[0][8] x:-26.000000 y:-26.000000 2010-04-15 23:44:48.850 RubixGL[4203:20b] vertex[1][9] x:-26.000000 y:-1.000000 2010-04-15 23:44:48.851 RubixGL[4203:20b] vertex[2][10] x:-1.000000 y:-26.000000 2010-04-15 23:44:48.852 RubixGL[4203:20b] vertex[3][11] x:-1.000000 y:-1.000000 2010-04-15 23:44:48.853 RubixGL[4203:20b] Next Face 2010-04-15 23:44:48.853 RubixGL[4203:20b] vertex[0][12] x:1.000000 y:-26.000000 2010-04-15 23:44:48.854 RubixGL[4203:20b] vertex[1][13] x:1.000000 y:-1.000000 2010-04-15 23:44:48.854 RubixGL[4203:20b] vertex[2][14] x:26.000000 y:-26.000000 2010-04-15 23:44:48.855 RubixGL[4203:20b] vertex[3][15] x:26.000000 y:-1.000000 any ideas?

    - by Without me Its just Aweso
    I'm looking for a way to do something similar to a c/c++ #define in adobe flex. I'd like to have lots of different paths a project build can take depending on wither or not something was defined. Does such a thing exist in flex? I know there is ways to set global variables but that wont really suit my purpose. being able to have structures with numerous #ifndefined and such is really what i'm in need of. thanks!

  • How to add separator between items in a Spark List control

    - by simms2k
    I have a s:List where I've defined my own itemRenderer, and would like to insert a horizontal line separating items, similar to the way the mx:LinkBar works. I don't want to have a line at the top or bottom of the list, so I can't just include an upper or lower border in the itemRenderer. I was hoping the itemRenderer could be made aware of its index in the list, but I don't see how. Is there a way to do this?

  • undefined method `bytes' for for String in Ruby

    - by artsince
    I am working with ruby 1.8.6 (2007-03-13 patchlevel 0) [x86_64-linux] and I get undefined method `bytes' for #<String:0x2a95ec2268> (NoMethodError) even though my code works on ruby 1.8.7. patchlevel 249 I saw somewhere that you need to add require "jcode" for a similar method not defined error with each_byte. I tried adding that but it still does not work. Any suggestions are very appreciated.

    for using cout, I need to specify both: #include<iostream> and using namespace std; Where is cout defined? in iostream, correct? So, it is that iostream itself is there in namespace std?

  • Sorting a List based on an ArrayList within a custom Object

    - by Matt Weldon
    I am using a list to keep track of a number of custom Row objects as follows: Public Rows As List(Of Row)() Row has 2 properties, Key (a String) and Cells (an ArrayList). I need to be able to sort each Row within Rows based on a developer defined index of the Cells ArrayList. So for example based on the following Rows Row1.Cells = ("b", "12") Row2.Cells = ("a", "23") Rows.Sort(0) would result in Row2 being first in the Rows list. What would be the best way of going about implementing this? Thanks

  • Max size of localStorage values?

    - by user269386
    Hi, since the localStorage (currently) only supports strings as values and in order to that the objects have to be stringified (stored as JSON-string), before they can be stored, i wondered if there is a defined limitation regarding the length of the values. Does anyone know if there is a definition which applies to all browsers, respectively does anyone know the limitations for Chrome5? Thanks, in advance, for your help

  • Allowed characters in linux environment variable names

    - by Christian Semrau
    What characters are allowed in linux environment variable names? My cursory search of man pages and the web did only produce information about how to work with variables, but not which names are allowed. I have a Java program that requires an defined environment variable containing a dot, like com.example.fancyproperty. With Windows I can set that variable, but I had no luck setting it in linux (tried in SuSE and Ubuntu). Is that variable name even allowed?

  • Debug vs Trace in C#

    - by koumides
    All, As I understand statements like Debug.WriteLine() will not stay in the code in the Release build. On the other hand Trace.WriteLine() will stay in the code in the Release build. What is controling this behaviour? Does the C# compiler ignores everything from the System.Diagnostics.Debug class when the DEBUG is defined? I am just trying to understand the internals of C# and just curious. Thanks, MK
