Compilation errors, createWindowContainer

[wierzbka]

Hey, I have a problem, when I buid my program, I receive error: 'createWindowContainer' is not a member of 'QWidget'. I use Qt 5.3.0,I thought I had all the Qt5.3 header files installed, but am I missing something? I don't know what I am doin wrong. Can you help me solve it?
This is my code:
@#include<QTimer>
#include<QWidget>
#include<QDockWidget>
#include "platforma.h"
#include "ui_platforma.h"
#include "qwt_plot.h"
#include "qwt_plot_curve.h"

Platforma::Platforma(QWidget *parent) :
QWidget(parent),
ui(new Ui::Platforma)
{
ui->setupUi(this);
cuboid = new Cuboid();
QWidget *c = QWidget::createWindowContainer(cuboid);
ui->cuboid_frame->layout()->addWidget(c);
timer = new QTimer(this);
connect(timer, SIGNAL(timeout()), this, SLOT(refreshPlots()));
timer->start(100);
initPlots();
cuboid->update();
}
void Platforma::refreshPlots()
{
receiver.receiveData();
cuboid->angleX = receiver.angleX->points.back().y();
cuboid->angleY = receiver.angleY->points.back().y();

cuboid->update();

}

void Platforma::initPlots()
{
receiver.accelerometerX->curve->attach(ui->accelerometerX);
receiver.accelerometerY->curve->attach(ui->accelerometerY);
}

Platforma::~Platforma()
{
delete ui;
}

void Platforma::on_pause_button_clicked()
{
if(timer->isActive())
{
timer->stop();
}
else
{
timer->start();
}
}

Hi and welcome to devnet,

Are you sure you are using a kit that uses Qt 5 ?

[wierzbka]

Yes, I am sure. Here is my screen

What does your .pro file look like, and what is the definition of a cuboid - does it inherit from QWindow ?

[wierzbka]

Thanks for answer. :)Here is my .pro file:
@QT += core gui 3dquick

QT += widgets

TARGET = Platforma
TEMPLATE = app

SOURCES += main.cpp
platforma.cpp
datastorage.cpp
datareceiver.cpp
cuboid.cpp

HEADERS +=
datastorage.h
datareceiver.h
platforma.h
cuboid.h

FORMS += platforma.ui

unix:!macx: LIBS += -L$$PWD/../../../../../../../../../lib/ -lqwt

INCLUDEPATH += $$PWD/../../../../../../../../../usr/include/qwt
DEPENDPATH += $$PWD/../../../../../../../../../usr/include/qwt@

and I used library Qt3D to create my cuboid, so it looks like:

@#include "cuboid.h"
#include "QGLBuilder"
#include "QGLCube"

Cuboid::Cuboid(QWidget *parent)
{
QGLBuilder builder;
builder << QGL::Faceted;
builder << QGLCube();
cuboid = builder.finalizedSceneNode();
angleX = 0;
angleY = 0;
}
void Cuboid::paintGL(QGLPainter *painter)
{
//cuboid->draw(painter);
painter->setStandardEffect(QGL::LitMaterial);

    painter->projectionMatrix().push();
    painter->modelViewMatrix().push();
    painter->modelViewMatrix().rotate(angleX, 1.0f, 0.0f, 0.0f);
    painter->modelViewMatrix().rotate(angleY, 0.0f, 0.0f, 1.0f);
    painter->modelViewMatrix().rotate(45.0f, 0.0f, 1.0f, 0.0f);
    cuboid->draw(painter);
    painter->projectionMatrix().pop();
    painter->modelViewMatrix().pop();
    painter->popSurface();

}
