[SOLVED]How to refresh TabText dynamically?



  • I have a QTabWidget and want to refresh the tab names dynamically. E.g., TabWidget has Tab1, Tab2, Tab3, Tab4 at the beginning. Then I close Tab2, the three Tab names should become Tab1, Tab2, Tab3.

    Now, I try to do it like follows:
    @ setUpdatesEnabled(true);
    for (int i = index; i < displayTabWidget->count(); i++) {
    tabName = "Curves";
    tabName += QString::number(i);
    setTabText(i, tabName);
    }
    displayTabWidget->repaint();@

    I put it inside the function closeTab(int index) and after removeTab(index) is called

    But this does not work...The Tab texts do not change

    Thanks a lot!



  • Hi, I've created a small MainWindow for you for that your code is working. Especially have a look on how you are using the setTabText function, without an object. Possibly you have derived your class from QTabWidget and mix some things up?

    @MainWindow::MainWindow(QWidget parent) :
    QMainWindow(parent)
    {
    QTabWidget
    tabWidget = new QTabWidget(this);
    setCentralWidget(tabWidget);

    tabWidget->addTab(new QWidget, "Tab 1");
    tabWidget->addTab(new QWidget, "Tab 2");
    tabWidget->addTab(new QWidget, "Tab 3");

    for (int i = 0; i < tabWidget->count(); i++) {
    QString tabName = "Curves";
    tabName += QString::number(i);
    tabWidget->setTabText(i, tabName);
    }
    }
