Problem：StackedWidget Page switching


  • I use Stackedwidget. There are some buttons to switch pages under the main interface. You can switch pages by clicking the button. But other pages are embedded in the middle of the interface by other windows. How do you do this?

    @Qt_HuangZiHan said in Problem：StackedWidget Page switching:

    By using layouts?
    But I'm not sure what you mean. Can you explain better what you want to do and what the problem is?

  • @jsulm In the middle of this page is a Stacked Widget. I created three index pages, but I also made three UI interfaces. Now I want to embed these three UI interfaces into the index page of Stacked Widget.

    @Qt_HuangZiHan There is an example right there in the documentation (https://doc.qt.io/qt-5/qstackedwidget.html):

    // Replace QWidget with your own widget
QWidget *firstPageWidget = new QWidget;
QWidget *secondPageWidget = new QWidget;
QWidget *thirdPageWidget = new QWidget;

QStackedWidget *stackedWidget = new QStackedWidget;
stackedWidget->addWidget(firstPageWidget);
stackedWidget->addWidget(secondPageWidget);
stackedWidget->addWidget(thirdPageWidget);

    There is also https://doc.qt.io/qt-5/qstackedwidget.html#insertWidget
    You also can use https://doc.qt.io/qt-5/qstackedwidget.html#widget to get the widget on the given tab and use it as parent for you widget which you add on top of it...

  • @jsulm Is that the case?

        SecurityMonitoring *new_SecurityMonitoring;
    SerialPort_ControlLED *new_SerialPort_ControlLED;

    void Widget::initWidget()
{
    new_SecurityMonitoring = new SecurityMonitoring;
    new_SerialPort_ControlLED=new SerialPort_ControlLED;
    ui->stackedWidget->addWidget(new_SecurityMonitoring);
    ui->stackedWidget->addWidget(new_SerialPort_ControlLED);
}

    Hi
    I read your issues as you want to do
    WidgetPtr->ui->stackedWidget->setCurrentIndex()
    but UI is private ?
    so from main widget, you want to let buttons switch paged for
    a other widgets stackedWidget ? ( the class Widget : public QWidget )
    Is that correct ?

  • @jsulm I tried my code, but it didn't work.

    @Qt_HuangZiHan If you say "didn't work" you should say what exactly did not work (or in what way it misbehaves).
