.net - C# List<T>.Find(x=>x.Rectangle.Contains(Point)) FAIL -

For my life, I can not understand why this code generates the following output ... I think there is a bug or something while using the list and lambda, if type one rectangle exposes the property and you use the included method of rectangle object ... and the clear statement proves true while Find list method fails .... Onway Code Public Gridskeyr Warldtokapadsb (Point location) {location = _Map.WorldToClient (location); Gridsquare gs = this.find (x => x.Rectangle.Contains (location)); GridSquare KP = G.Find (X => X. laxative canteen (location)); & Lt; GridSquare & gt; List = kp.FindAll (x => x.Rectangle.Contains (location)); U.dp (list.Count); Gridskare sub = KP.Fid (X => X. laxative canteen (location)); If (sub == faucet) {u.dp (place to look for "location"); U.dp ("The location found in the grid category" + GS toaster ()); U.dp ("Grid Square Bounds" + gs.Rectangle.ToString ()); U.dp ("location found in keypad" +...

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...
