mdi area and subwindow

[sajis997]

Hello forum,

I am trying to insert the elastic node example inside the window structure as follows:

ElasticMainWindow::ElasticMainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::ElasticMainWindow),
    m_graph(0),
    m_mdiArea(0),
    m_subWindow(0)
{
    ui->setupUi(this);
 
    //create a mdi area
    m_mdiArea = new QMdiArea(this);
    m_mdiArea->setOption(QMdiArea::DontMaximizeSubWindowOnActivation,false);
 
    createToolWindows();
 
    //!set the mdi area as the central widget
    //!and this is how it is used in the main window
    setCentralWidget(m_mdiArea);
 
}
 
 
void ElasticMainWindow::createToolWindows()
{
 
 
    m_graph = new GraphWidget();
    m_graph->setWindowTitle(tr("Elastic Graph"));
 
 
    m_subWindow = new QMdiSubWindow(m_graph,Qt::FramelessWindowHint);
 
 
    m_mdiArea->addSubWindow(m_subWindow)->setWindowState(Qt::WindowMaximized);
 
 
 
}
 
ElasticMainWindow::~ElasticMainWindow()
{
    delete ui;
}

ElasticMainWindow::ElasticMainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::ElasticMainWindow),
    m_graph(0),
    m_mdiArea(0),
    m_subWindow(0)
{
    ui->setupUi(this);

    //create a mdi area
    m_mdiArea = new QMdiArea(this);
    m_mdiArea->setOption(QMdiArea::DontMaximizeSubWindowOnActivation,false);

    createToolWindows();

    //!set the mdi area as the central widget
    //!and this is how it is used in the main window
    setCentralWidget(m_mdiArea);

}


void ElasticMainWindow::createToolWindows()
{


    m_graph = new GraphWidget();
    m_graph->setWindowTitle(tr("Elastic Graph"));


    m_subWindow = new QMdiSubWindow(m_graph,Qt::FramelessWindowHint);


    m_mdiArea->addSubWindow(m_subWindow)->setWindowState(Qt::WindowMaximized);



}

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

To copy to clipboard, switch view to plain text mode 

But i do see anything when the program launches. It should be showing the nodes and edges connected to each other as in the main example.


Please point out if i miss anything.
