android toolbar for pre lollipop devices -

-

When I changed from ActionBar to Toolbar, I had to face many issues. I listed them here

1 ) I have several pieces that have been changed / using backstacks. Everything was working fine when I pressed the back button, but when I switch to the toolbar, the application closes when I press the back button.

2 ) The background of the popup menu is black 

  & lt; Item name = "Android: popup menu style" & gt; @ Style / popup menu & lt; / Item & gt; & Lt; Style name = "PopupManu" parent = "@ Android: Style / widget. Popup menu" & gt; & Lt; Item Name = "Android: Popup Background" & gt; @Android: color / white & lt; / Item & gt; & Lt; / Style & gt;

Even this did not work.

If I use AppCompat. The light theme, the background color of the popup menu is white, but then the navigation indicator icon and black

3 ) This is my menu style, the item "add" is not shown here with id. Instead, I have always used showAsAction in this menu (in the menu when I press that 3 vertical dots button), but the icon appears Does not. 

  & lt; Menu xmlns: android = "http: // schema .android.com / apk / ridge / android" xmln: tools = "http://schemas.android.com/tools" tool: reference = ".com.hirak.assistere_doit .do_it_main_screen "& gt; & Lt; Item android: id = "@ + id / action_settings" Android: orderInCategory = "100" Android: showAsAction = "never" android: title = "settings" /> & Lt; Item android: id = "@ + ID / Add" Android: Icon = "@ Drable / Ed" Android: ShowAsaction = "Always" /> & Lt; / Menu & gt;

For the popup menu style, you need to apply a popup

& lt; Android.support.v7.widget.Toolbar Android: AD = "@ + ID / toolbar" app: subject = "@ style / actionbore" Android: layout_width = "match_perrent" android: layout_hete = "wrap_content" app: popuptheme = " @ Style / Toolbops "/>

And then in your theme, override the values ​​you want to change

Add to your Toolbar to whiten the Navigation Indicator 

  & lt; Style name = "ActionBar" parent = "Widget.AppCompat.Toolbar" & gt; ... and lieutenant; Item name = "Android: Text collar secondary" & gt; @color / white & lt; / Item & gt; & Lt; Item name = "Action menu textclosure" & gt; @color / white & lt; / Item & gt; & Lt; Item name = "android: textColorPrimary" & gt; @color / white & lt; / Item & gt; & Lt; / Style & gt;

For back button issues, I'll need more information - code etc.

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. ...
