[SOLVED] C++ Function Calls

[overtime]

I get this error:

@C:\Users\Darrel\Desktop\smartphonebrainscanner2-Brain3D\qmlapplicationviewer\qmlapplicationviewer.cpp:77: error: no matching function for call to 'QQuickView::QQuickView(QWidget*&)'
, d(new QmlApplicationViewerPrivate())
^@

From this code:

@
QmlApplicationViewer::QmlApplicationViewer(QWidget *parent)
: QQuickView(parent)
, d(new QmlApplicationViewerPrivate())
{
connect(engine(), SIGNAL(quit()), SLOT(close()));
setResizeMode(QQuickView::SizeRootObjectToView); //(QDeclarativeView::SizeRootObjectToView); Qt 4.8

// Qt versions prior to 4.8.0 don't have QML/JS debugging services built in

#if defined(QMLJSDEBUGGER) && QT_VERSION < 0x040800
#if !defined(NO_JSDEBUGGER)
new QmlJSDebugger::JSDebuggerAgent(engine());
#endif
#if !defined(NO_QMLOBSERVER)
new QmlJSDebugger::QDeclarativeViewObserver(this, this);
#endif
#endif
}@

@class QmlApplicationViewer : public QQuickView //QDeclarativeView // Qt 4.8
{
Q_OBJECT

public:
enum ScreenOrientation {
ScreenOrientationLockPortrait,
ScreenOrientationLockLandscape,
ScreenOrientationAuto
};

explicit QmlApplicationViewer(QWidget *parent = 0);
virtual ~QmlApplicationViewer();

static QmlApplicationViewer *create();

void setMainQmlFile(const QString &file);
void addImportPath(const QString &path);

// Note that this will only have an effect on Fremantle.
void setOrientation(ScreenOrientation orientation);

void showExpanded();

private:
class QmlApplicationViewerPrivate *d;
};@

It's been awhile since I've worked on C++ classes so I'm pretty rusty. I don't see the problem.

You are calling a constructor while you haven't defined any for the class you mention, I think that might be the reason why it is not working.
First define a constructor then you can call @new QmlApplicationViewerPrivate()@

[overtime]

isn't it already defined in

@private:
class QmlApplicationViewerPrivate *d;@

and then here is this:

@
class QmlApplicationViewerPrivate
{
QString mainQmlFile;
friend class QmlApplicationViewer;
static QString adjustPath(const QString &path);
};@

Well the first thing is that I don't see why you are using the key word "class" here
@private:
class QmlApplicationViewerPrivate *d;@
Indeed, if your class QmlApplicationViewerPrivate is defined in a .h you can simply include it in your QmlApplicationViewer file ;).

As for this part of the code here :
@class QmlApplicationViewerPrivate
{
QString mainQmlFile;
friend class QmlApplicationViewer;
static QString adjustPath(const QString &path);
};@

You are indeed defining a class with its attributes and methods, but I don't see any constructor which goes like : QmlApplicationViewer(type1 att1, type2 att2...){
}

perfect, thank you :)

You're very welcome ! Please mark the topic as solved and good luck with the rest of your coding ;-)
