objective c - How to implement delegate protocol between two NSViewControllers which are managed by an NSSplitViewController -

-

I'm new to Mac OS X development, I know how to work with the protocol in iOS app development and I understand how he works, now I have a small project in which there is a NSSplitViewController in which there are two NSSplitViewItems and that is related to NSViewControllers ProjectsVC and TasksVC, I am using xCode 6 with the storyboard NSSplitViewController

In ProjectsVC, let me find this pro Ocol is 

  @protocol projectsVCDelegate & lt; NSObject & gt; - (Zero) Selected Project: (JT Project ™) project; @end

The question is, how to get an example of ProjectsVC to set up a worker to work in ProjectsVc?

When you think of such problems, think about how to decompose things. In a way, your Split View Controller relationship will have to be managed. As soon as your ProjectsVc works as a representative for the JointProject, your Split View Controller can work as a representative for your projects VC. You can call a method by which the SVC knows something that it can take some care, and then it can do something in response, such as calling any method that works on efficiency.

BENEFIT: Projects know something about TaskCVC, TaskCVC does not know about projects they are managed by an object that uses those resources to fulfill more complex domain tasks. Is allowed.

To implement an Assign property project to project VCCLEG and Projects VC to Split View Controller VCDelegate Forwarding that Split View Controller Assigns itself Projects VC - (Zero) Selected Project: (JTPOJeked * ) Project {[self.projectCVDelegateForward was selected Project: Project];} Split View Controller - (Zero) Selected Project: (J. TTOject *) project {{self.tasksVC doSomethingRelatedTolectedProject: project];}

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. ...
