QMainWindow

 

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 :

  1. QXSRExample::QXSRExample(QWidget *parent) : QMainWindow(parent) {
  2.     setupUI();
  3. }
  4. QXSRExample::~QXSRExample() {
  5. }
  6. void QXSRExample::setupUI() {
  7.      QFrame* frame = new QFrame(this);
  8.  
  9.     _layout = new QVBoxLayout;
  10.  
  11.     frame->setLayout(_layout);
  12.  
  13.     parseXML();
  14.  
  15.     QScrollArea* scrollArea = new QScrollArea;
  16.  
  17.     scrollArea->setWidget(frame);
  18.  
  19.     scrollArea->setWidgetResizable(true);
  20.  
  21.     setCentralWidget(scrollArea);
  22. }
  23.  
  24. ………
  25.  
  26. void QXSRExample::details(QTreeWidgetItem* item,int column){
  27.  
  28.     itemName= item->data(column, Qt::DisplayRole).toString();
  29.  
  30.     QFrame* frame2 = new QFrame(this);
  31.  
  32.     _layout = new QVBoxLayout;
  33.  
  34.     frame2->setLayout(_layout);
  35.  
  36.         QScrollArea* scrollArea = new QScrollArea;
  37.  
  38.     scrollArea->setWidget(frame2);
  39.  
  40.     scrollArea->setWidgetResizable(true);
  41.  
  42.     setCentralWidget(scrollArea);
  43.  
  44.    
  45.     while(!persons3.isEmpty()) {
  46.  
  47.         QMap<QString,QString> person = persons3.takeFirst();
  48.  
  49.         if ((person["surname"]==itemName) or (person["name"]==itemName)){
  50.  
  51.             QGroupBox* personGB = new QGroupBox("Patient");
  52.  
  53.             QFormLayout* layout = new QFormLayout;
  54.  
  55.             layout->addRow("ID", new QLineEdit(person["id"]));
  56.  
  57.             ………….
  58.             personGB->setLayout(layout);
  59.  
  60.             this->_layout->addWidget(personGB);
  61.  
  62.         }
  63.     }
  64.      QPushButton* ok = new QPushButton("Return");
  65.  
  66.      _layout->addWidget(ok, 1, Qt::AlignCenter);
  67.  
  68.      connect(ok, SIGNAL(clicked()),this, SLOT(cancel()));
  69. }

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

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.
