c++ - QtQuick: QQmlApplicationEngine failed to load component qrc:/main.qml:23 Invalid attached object assignment -


Looking at my thoughts below, am I barking the wrong tree? Or in the information given below, am I misusing the Qt API to get an error in the title?

I'm trying to modify the sample to work with the default coefficic project generated from Qt Creator 3.3.0 (OpenSource). Qt 5.4.0 (GCC 4.6.1, 64bit) Based on.

The first thing to look at after the code is that I stand by:

The sample uses the main.cpp: 

  qmlRegisterType & lt ; Squircle & gt; ("OpenGLUARMM", 1, 0, "Squircle"); QQuickView view; View.setResizeMode (QQuickView :: SizeRootObjectToView); View.setSource (QUrl ("QRC: ///scenegraph/openglunderqml/main.qml")); View.show ();

Some name changes in my name. CPP 

  qmlRegisterType & lt; Menuscreen & gt; ("OpenGLUnderQML", 1, 0, "Main Screen"); QQmlApplicationEngine engine; Engine.load (QUrl (QStringLiteral ("QRC: /main.qml")));

I'm not sure that the difference in using QQmlApplicationEngine on a QuickView can cause my error:

QQmlApplicationEngine component failed to load qrc Is: / main .qml: 23 - Invalid Attached Object Assignment

Where my main XML looks: 

  Import Cactiq 2.4 Import QtQuick.Window 2.2 Import OpenGLUnderQML 1.0 Import "qmlmodel" Window {ID: Width of Main Window: 800 Height: 600 Appearance: True Color : "Black" Title: "Army calculator" ObjectName: "Main window" list view {ID: Mainlist view anchor. Fill: Basic ObjectName: "Mainlist View"} Main Screen {Graduate animation on deltati {NumberAnimation {to: 1; Duration: 2500; Easing.type: Ease Inquisition} number animation {to: 0; Duration: 2500; Simplicity: typing: easy. Octquaed} loop: animation. The infinite is running: true}}} and the sample uses it:  
  import cautious 2.0 imported OpenGLUARMML 1.0 item {width: 320 height : 480 Squircle {T {Number Animation {Sequential Animation {From: 1; Duration: 2500; Easing.type: Ease Inquisition} number animation {to: 0; Duration: 2500; Simplicity: Typing: Easy. Otkwad} loop: animation. Infinity is running: true}} rectangle {color: Q. RGBA (1, 1, 1, 0.7) radius: 10 limit. Width: 1 border Colal: "white" anchor .Fil: Label anchor. Margin: -10} text {id: label color: "black" RAM mode: text. Word Lesson: "Background Here is a squircle provided with raw OpenGL using the 'firsthander ()' signal in QuickWindows. This text label and its border QML" anchors.right: parent.right anchors.left: parent .left anchors.bottom: parent.bottom anchors.margins: 20}} is provided using  
 
 
 In the comment given below, according to the request is MainScreen.h 
 
  #ifndef MAINSCREEN_H #define MAINSCREEN_H #include & lt; QQuickItem & gt; Class main screen renderer; Class QQuickWindow; Classroom Homescreen: Public QQuickItem {Q_OBJECT Q_PROPERTY (qreal deltati READ getDeltaT WRITE set DELTAT NOTIFY deltaTChanged) Public: home screen (); ~ MainScreen (); Qreal getDeltaT () console; Zero set deltaT; Signal: Zero Delftify (); Public slots: zero sync (); Zero cleaning (); Private Slots: Wide Handwindows Change (Quwwwondo * Win); Private: qreal m_DeltaT; Main Spring Renderer * M_Renderer; }; #endif // MAINSCREEN_H

The property name should start with lowercase letters. You need to convert DeltaT to deltaT.

MainScreen.h 

  Q_PROPERTY (qreal deltaT READ getDeltaT WRITE set DeltaT NOTIFY deltaTChanged)

Main.qml

main screen (sequential animation at deltaT {}}

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...
