Setting context property for a QQuickView crashing? [SOLVED]

[EStudley]

Hey there. So I'm having a problem accessing the functions from a class that inherits QObject in my QMainWindow. Here's the initializer for my MainWindow:

@MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

QQuickView *view = new QQuickView;
cryptsyAPI cryptsyInterface;
view->engine()->rootContext()->setContextProperty("Cryptsy", &cryptsyInterface);
view->setFlags(Qt::Dialog);
view->setSource(QUrl("qml/Bit-sy/main.qml"));

}@

cryptsyAPI is a class that inherits QObject. Here's the .h file:

@class cryptsyAPI : public QObject
{
Q_OBJECT

public:
explicit cryptsyAPI(QObject *parent = 0);
~cryptsyAPI();

public slots:
void timedAPIRefresh();
};@

"TimedAPIRefresh" right now only outputs "Hello" to the console with qDebug().
Everything works and compiles perfectly fine, but when I try to access the function from QML, like so:

@ onClicked:{
Cryptsy.timedAPIRefresh();
}@

The program crashes. Any idea why? When I open the crash report in Visual Studio, it says "Unhandled exception at 0x000000006D100432 (Qt5Qml.dll) in Bit-sy.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF."

Hi,

Just an educated guess but cryptsyInterface is destroyed at the end of the constructor so accessing it should trigger the crash.

Thank you so much! I had been working on that for several hours when I posted this, I wasn't thinking clearly!
