gsettings - How to handle errors while using Glib.Settings in Vala? -

-

I am using Glib.Settings in my Vala application. And I have to make sure that my program will work properly even if the schema or key is not available. So I've added an attempt / catch block, but if I'm using the key that does not exist, the program segfaults. As I understand, it does not even reach the catch statement. Here is the function that uses the settings: 

  GLib.Settings settings; String token = ""; Try {settings = new GLib.Settings (my_scheme); Tokens = settings.get_string ("token1"); } Hold (error e) {print ("error"); Token = ""; } Return token;

and program output is: 

  (Main: 27194): GLib-GIO-ERROR **: Settings key in schema 'my_scheme' Token1 'trace / breakpoints trap (core dump)

(Of course I am using my real scheme instead of my_scheme) Can you suggest me where I am wrong? Methods, code in get_string

GLib.Settings > Do not throw exceptions, they call abort inside the library. This is not an ideal design, but you can not do anything about it.

In this case, correct your schema to work correctly, / usr / share / glib-2.0 / schema and on that directory (as code) Glib-compile-schemas .

Vala has examined only the exceptions, therefore, the opposite method of C # declares should declare that it will throw, or it is not possible to do so. You can always double check to see Wadakock or VAPI.

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. ...
