ios - Swift: add custom view inside CALayer -

-

I am trying to add a custom view inside the CALayer.

And I want to put some buttons and labels inside, but I'm afraid I am not able to do this. I am creating CALabel like this: 

  func addRectangleToLayer (x: CGFloat, y: CGFloat, width: CGFloat, height: CGFloat, layer: CALayer, index: UInt32) {var sublayer = CALayer () Sublayer.backgroundColor = UIColor.whiteColor (). CGColor sublayer.shadowOffset = CGSizeMake (0, 3); Sublayer.shadowRadius = 5.0; Sublayer.shadowColor = UIColor.blackColor (). CGColor sublayer.shadowOpacity = 0.8; Sublayer.cornerRadius = 12.0; Sublayer.frame = CGRectMake (X, Y, width, height); Sublayer.borderColor = UIColor.blackColor () CGColor; Sublayer.borderWidth = 0.5; // Give an example label = UILabel () label.text = "LOREN" sublayer.contents = label layer.insertSublayer (sublayer, at index: index)}

Is it possible to do this I want

Many thanks and sorry for my English level

If you UIView , you will have access to its Layer property for this purpose: 

  label = UILBL () label .text = " LOREN "var sublayer = label.layer; // .. Rest of your layer initial sublayer.backgroundColor = UIColor.whiteColor (). CGColor sublayer.shadowOffset = CGSizeMake (0, 3); Sublayer.shadowRadius = 5.0; Sublayer.shadowColor = UIColor.blackColor (). CGColor sublayer.shadowOpacity = 0.8; Sublayer.cornerRadius = 12.0; Sublayer.frame = CGRectMake (X, Y, width, height); Sublayer.borderColor = UIColor.blackColor () CGColor; Sublayer.borderWidth = 0.5; // The original source initialization layer has ended. InsertsBlare (sublighter, index: index)

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. ...
