I am using singleSort() method but it sorts case sensitively. For example, data = ['c', '1', 'A', 'a', 'C'] output = ['1', 'A', 'C', 'a', 'c'] myoutput = ['1', 'a', 'A', 'c', 'C'] or [['1', 'A', 'a', 'C', 'c'] // This is what I want Any suggestion on how to achieve this? 回答1: Add this to your code... be wary of your scopes because you will make all sorts on the page case insensitive. I found this code on the forums and have used it successfully in 3

Since I need to use the model in QML, I cannot make use of the sorting functionality Qt widgets and views have integrated. I tried using a QSortFilterProxyModel but it doesn't seem to work with my model. Getting the model to properly work in QML wasn't tedious enough, and now I am stuck on sorting. Any suggestions are appreciated. Here is the model source: typedef QHash<QString, uint> Data; class NewModel : public QAbstractListModel { Q_OBJECT Q_PROPERTY(int count

I have a column of dates that I put in for something, in the following format 14/6/2012 15/12/2012 16/2/2012 17/9/2012 17/10/2012 17/11/2012 And so on like that. However when I try and sort them, it only sorts based on the first number, as I've shown above. When I highlight the data, at the top of window in excel, it doesn't say general anymore it says date so I assume excel knows that they're dates. However if I go to sort and filter to try and choose a few

I am trying to reverse this, so the initial click sorts Descending then the second click sorts Ascending and I haven't been able to figure out how to do this. Does anyone know? Thanks 回答1: You can set the HeaderCell SortGlyphDirection to Ascending, and then the next click will give you the descending order. The default is none.

That is, it's still ordering them as the same letter like this (old definition for Swedish ordering): Wa Vb Wc Vd it should be (new definition for Swedish ordering): Vb Vd Wa Wc The examples gives: Ordering One to respect locale. By then using the second item (object id) in each tuple I could fetch the correct object in Django. I'm starting to doubt that this will be possible? Would upgrading PostgreSQL to a newer version

The following works fine: def books = Book.findAll("from Book as b where b.approved=true order by b.dateCreated desc", [max: max, offset: offset]) But what I want is: def books = Book.findAll("from Book as b where b.approved=true", [sort: 'dateCreated', order: 'desc', max: max, offset: offset]) This does not work. How do I have to rewrite this? 回答1: HQL doesn't support sort and order as parameters, so you need to include the "order by" as part of the HQL expression def books

My raw data looks like the following: { "_id" : ObjectId("52deab2fe4b0a491abb54108"), "type" : "build", "time" : ISODate("2014-01-21T17:15:27.471Z"), "data" : { "buildNumber" : 43, "buildDuration" : 997308, "buildProjectName" : "TestABC", "buildResult" : "SUCCESS" } } I would like to sort this first by buildProjectName and then date. Here is my query: db.builds.aggregate([ { $group: { _id: { month: { $month: "$time" }, day: { $dayOfYear: "$time" }, year: { $year: "$time" },

Pretty much having the same result as TreeView.Sort() . I have a TreeView that continually grows to a couple hundred nodes. The user can view this TreeView in real time as it grows. I'd prefer to just insert the nodes at the correct index, rather than calling TreeView.Sort() each time after a node is added. Can this be done? 回答1: In winforms,

I can see the DOM gets modified with the spinner code, however it does not display. I was hoping there may be something I can do to force this display of spinner before the sort happens, and of course stop it when the sort is completed. My sort is based on 'sorttable.js' which I have modified to handle a secondary sort on the first column of table (with
