javascript - Angular $watch doesn't get triggered -

-

I am trying to write a instructions for drawing barcharts, and I want to repeat the data every time from the chart Are the changes I currently have this: 

  / * This instruction will create a bar chart based on the datatable * It expects the label in the first column of the data table to be included. * If more than 2 columns (labels have more than one value) are supplied, * All bars generated from values ​​in one line will be grouped together, * An easy visual comparison (benchmark). * If the option overlay is supplied, weird price columns will be created (with the [x [label, cola 1, cola 2, to 3, to 4] with the [below] * result with call 1 and call 3 * (* 'Window', '$ location', '$ parse', '$ timeout', function ($ window, '$'), and 'col4 * / angular.module' ('kapstok' $ Location, $ parse, $ timeout) {return: Restrict: 'E', Scope: true, link: function (scope, elm, ethers) {// read all different parameters in the DIRECTIVITY declaration GEVIEN If options are not given, they are replaced by their default values. Var Datagator = $ paras (attrs.data); var data = datagram (scope); undefined; if (! Data) { Throw error ("No (legitimate) data source specified!");} // Once the table has been updated, redo on the table. However, usually several elements of the table // will be updated at the same time, while the clock Will be triggered // on every update To stop, we give it an end of half a second, allowing // to apply all updates before the table is ready again. Radius $ Watch (function () {return data.getVersion ();}, $ timeout (draw chart, 500));

Then, in my controller I do: 

  controlmodule.controller ('PrefscanController', ['$ http', '$ scope', ' $ Scope.myData.addColumn ("string", "label"); $ scope.myData.addColumn ("number", "dataTable", function ($ http, $ scope, dataTable) {$ scope.myData = new datatale () $ Scope.myData.addColumn ("number", "break-it"); $ scope.myData.addRow (['test', 20, 10, 4]); $ scope.myData.addRow (['test2' , 42, 13, 2]); $ scope.hideBenchmark = function () {console.log ("myData.version =", $ Scope.myData.getVersion ()); $ scope.myData.hideColumn (2); console .log ("myData.version =", $ scope.myData.getVersion ());}

In all the functions from the datatable, whenever something changes, the one called 'version' Property b I need $ Watch to see me.

In my template then I have a button, an NG-click which calls the hide-in benchmark function. This function is said by GE T The datatable version has been updated, but whichever I try, the clock will not be triggered.

I have $ scope. $ Appy () / $ scope To hide the $ digest () benchmark function, try to make the clock 'true' (in search of inequality object), tried attr.d '', 'data.version' and any of the clock Begin to trigger! I know that I can make another variable, and I change the data every time I change the data on the free radius from this data, but it seems ugly and unnecessary.

Does anyone know why the clock is not starting, and what do I want to do for it?

Regards,

Linus

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
