QMainWindow

annatz

I have created a main window with a qvboxlayout where I have placed a combobox, a tree widget and the button ok. When I click the button ok, I create a new qvboxlayout with some widgets. The new qvboxlayout has the button return. How can I return to the first window with the choices of the user?
Do I have to create a new MainWindow or is there a function that does the whole work?

The code is :

@
QXSRExample::QXSRExample(QWidget parent) : QMainWindow(parent) {
setupUI();
}
QXSRExample::~QXSRExample() {
}
void QXSRExample::setupUI() {
QFrame frame = new QFrame(this);

_layout = new QVBoxLayout;

frame->setLayout(_layout);

parseXML();

QScrollArea* scrollArea = new QScrollArea;

scrollArea->setWidget(frame);

scrollArea->setWidgetResizable(true);

setCentralWidget(scrollArea);

}

………

void QXSRExample::details(QTreeWidgetItem* item,int column){

itemName= item->data(column, Qt::DisplayRole).toString();

QFrame* frame2 = new QFrame(this);

_layout = new QVBoxLayout;

frame2->setLayout(_layout);

    QScrollArea* scrollArea = new QScrollArea;

scrollArea->setWidget(frame2);

scrollArea->setWidgetResizable(true);

setCentralWidget(scrollArea);


while(!persons3.isEmpty()) {

    QMap<QString,QString> person = persons3.takeFirst();

    if ((person["surname"]==itemName) or (person["name"]==itemName)){

        QGroupBox* personGB = new QGroupBox("Patient");

        QFormLayout* layout = new QFormLayout;

        layout->addRow("ID", new QLineEdit(person["id"]));

        ………….
        personGB->setLayout(layout);

        this->_layout->addWidget(personGB);

    }
}
 QPushButton* ok = new QPushButton("Return");

 _layout->addWidget(ok, 1, Qt::AlignCenter);

 connect(ok, SIGNAL(clicked()),this, SLOT(cancel()));

}

EDIT: please only use one @-tag in the beginning of the code, and one in the end, Gerolf

hi, can u fix the code format by enclosing it with @ tag? not readable right now

you replace the centralWidget of the main window, so you must move it back.
An other option woukd be to use a stacked widget (QStackedWidget) and switch between them.
