i got a godgiven list of xyz (the code says int, just an example) glued into a QList (to big to move anywhere). How can I create a Model View for that? I allready read the Qt doc which tells me, I have to reimplement data, index, parent, rowCount, columnCount functions. But the preprocessor/compiler cries for more reimplemented functions...
c2=[] row1=[1,22,53] row2=[14,25,46] row3=[7,8,9] c2.append(row2) c2.append(row1) c2.append(row3) c2 is now: [[14, 25, 46], [1, 22, 53], [7, 8, 9]] how do i sort c2 in such a way that for example: for row in c2: sort on row[2] the result would be: [[7,8,9],[14,25,46],[1,22,53]] the other question is how do i first sort by ro...

Suppose I have a single element, and I have a list of predicates (functions). I want to apply each of these predicates to the single element and get a corresponding list of return values. I know that map and friends can apply a single function to each a list of arguments, but is there any concise syntax to apply many functions to a singl...

Hey guys, so I am creating a List(Of String), always of size 9. This list contains True/False values. I need to go through this list and find the 3 values that are True (will never be more than 3, but could be less) and then set 3 string values in my code to the 3 index's of those values + 1. Here is my current code: Private Sub SetDe...
I tried to find a solution for now ~30min and couldn't find any. I am trying to set up the code style in CDT so it gives me: MyClass::MyClass() : var1(1), var2(2), var3(3){ } instead of MyClass::MyClass() : var1(1), var2(2), var3(3){ } but I couldn't find an option to do so. The only 'initializer list' option I could f...
I don't think this has been asked yet, but is there a way to combine information of a list with multiple levels and uneven structure into a data frame of "long" format? Specifically: library(XML) library(plyr) xml.inning <- "http://gd2.mlb.com/components/game/mlb/year_2009/month_05/day_02/gid_2009_05_02_chamlb_texmlb_1/inning/inning_5....

Before I embark on writing my own, is there a List like construct that also contains a Dictionary like key? And before someone suggests using a Dictionary instead, the order of items is important to me and Dictionary cannot guarantee a position. So, I'd like to be able to retrieve the item in the following manner: int position = 4; M...
Hi all, I have a list in scala called l : List[AType] that I want to change to list[String]. This may sound like a very dirty, inefficient approach, but I'm not quite sure of the best way to do this. My code was: var result = new Array[String]("a","b") l foreach { case a => result = result :+ (a.toString().toUpperCase()); } result toL...

Hallo, I have a problem with value transfer from a list to another in VB2008. I have 2 lists of string with same number of member that reference to their object-collections separately. I want to overwrite memory slots of list1 with the values of list2 without creating new memory slots. How can I do these? Thx. Lert ...
I am confused by the use of the ellipsis (...) in some functions, i.e. how to pass an object containing the arguments as a single argument. In Python it is called "unpacking argument lists", e.g. >>> range(3, 6) # normal call with separate arguments [3, 4, 5] >>> args = [3, 6] >>> range(*args) # call with argumen...
