osx - How to retrieve the location of an item in the Resources folder of an OS X application bundle, in Qt -

-

I need to obtain the application directory or executable path.

I've found that 

  QString appPath = QCoreApplication :: applicationDirPath ();

There will be a way to do this.

But when I run, I get an error: 

  QCoreApplication :: applicationDirPath:

If I run the Quark application I try to make an example, though I am creating errors ... 

  Error: No matching function: Using QApplication instead of QCoreApplication, I get a similar error.  
 This call is not created by the main () which is an application type class instantly ... it is very far from a config class.  
 How is this done?  
 Qt 4.8  
 Note: What I'm trying to get is the actual app directory (for Mac, I will use it to create a full path for content / resources ).  
 The relative path was not used (when I used to print the path before the relative path part, and failed to load the file I tried to load)  < Instead of pre>  @ / myapplication.app/Contents/Resources/myfile  

  path / myapplication.app / content / resource / Myfile

To use the file or object in the resource folder, it would be possible executable Start from the place and work from there Please. However, if the apple decides to change the format of the bundle, then this can be a problem.

As QT does not provide it directly, I suggest using the Apple Core Foundation, which can be used within QT applications. Suppose we want a resource named "itemName", which resides in the resource folder and we will get our full path in the path in the QString item: - 

  // Find the object path. QString itemPath; {CFRRF APR URLRF; AppUrlRef = CFBundleCopyResourceURL (CFBundleGetMainBundle), CFSTR ("itemName"), CFRT ("bundle"), null); CFStringRef MacPath = CFURKPFile System Path (APRLLR, KCFRRPOSISXTPSTL); Madpath = CF stringGet's StringPrint (McPath, CF StringGetSystem Encoding); // The main foundations should be issued CFRs (APRLLF); CFRelease (macPath); }

To use core forward functions, just include in your repatriation file: - 

  #include & lt; Corefoundation / CFBundle.h & gt;

Add relevant structure to project file (.pro) 

  LIBS + = -framework corinthation

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. ...
