c++ - Qt : how to automate looped slider movement in the background? -

-

A button is pressed, so what is the easiest approach to move the slider to a slider at a speed? I am feeling that a thread has been included in the frame, which periodically sends the appropriate signals to the slider. Is there an example of a canonical approach to do this?

i QPropertyAnimation to start the job simply start value, end value and curve Set which you want to change the value 

  QPropertyAnimation * animation = new QPropertyAnimation (slider, "sliderpages"); // Defined duration (how long should the animation run - when value will decrease, then less) Animation-> Set period (1000); // Set the Start Price - In this case, check that the slider will have values ​​in the range of animation-> Setstart Value (slider-> minimal;);); // Start value similar to animation-> Set and value (slider-> maximum ()); // easingCurve defines whether it goes directly or N-content animation jumping-> Set ESSCV (QEasingCurve :: Outcubic); // like coyote has been mentioned, you can also get it in the form of animation (credit also ;;)) 1-1 defines to run animation forever- & gt; Set Lopcast (LoopCount) Animation - & gt; Start ();

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. ...
