POconnect from a QTab (in a QTabWidget) back to QMainWindow

Body
copied!<p>The main Part of my Application is a Systray-Menu. For maintenance there should be a normal GUI.</p> <p>My Problem is that now I have to create two Signal/Slot-Connections back to the MainWindow from each Tab. This is for minimizing the GUI and to update the Menu. I don't know how to do this.</p> <p>I tried to connect with <code>this->parent->parent</code> from the ManageSession and <code>ui_manag->session_ui->minimizeButton</code> from MainWindow. I have a little knot in my head and am asking for help. Or should I re-think my design? I´m using only QtCreator 2.6.1 with Qt 4.8.4.</p> <p><a href="http://firewall.ztweb.de/StackOverflow-Screenshots.jpg" rel="nofollow">Screenshots of the GUI-Elements</a></p> <p>This is the mainwindows.cpp:</p> <pre><code>MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) { setWindowTitle(QCoreApplication::applicationName()); QWidget *mainWidget = new QWidget; QTabWidget *ui_manag = new ManageTab; QVBoxLayout *mainLayout = new QVBoxLayout; mainLayout->addWidget(ui_manag); mainWidget->setLayout(mainLayout); setCentralWidget(ui_manag); ui_manag->setCurrentIndex(0); //Here comming Code to setup a TrayIcon, the Database and the Menus } </code></pre> <p>The Tab is completely generated by the Designer:</p> <pre><code>ManageTab::ManageTab(QWidget *parent) : QTabWidget(parent), tab_ui(new Ui::ManageTab) { tab_ui->setupUi(this); } </code></pre> <p>For each Setting I use the same GUI with multiple inheritance:</p> <pre><code>ManageSession::ManageSession(QWidget *parent) : QWidget(parent), session_ui(new Ui::ManageWidget) { session_ui->setupUi(this); session_ui->manageLabel->setText(tr("Manage Session")); connect(session_ui->addButton, SIGNAL(clicked()), this, SLOT(addButton_clicked())); connect(session_ui->editButton, SIGNAL(clicked()), this, SLOT(editButton_clicked())); connect(session_ui->deleteButton, SIGNAL(clicked()), this, SLOT(deleteButton_clicked())); } //Here follows the Functions for manipulating the TableView // and emmiting a Signal to Update the Menu </code></pre>
