How to dynamically add QPushButton in QStackedWidget?

sys1

QStackedWidget is already complete by QT creator.
but I want add QPushButton in QStackedWidget as coding(C++).
What I want to do is add a new button to the bottom of the current screen
when I press a button that already exists in the QStackedWidget.

Below are some of the sources.

=====================================================

QPushButton* nextButton = new QPushButton();
nextButton->setText(QString::fromLocal8Bit("next"));
nextButton->setGeometry(QRect(QPoint(1150, 620), QSize(93, 28)));
connect(nextButton, SIGNAL(clicked()), this, SLOT(readCustomerGraph()));
ui.StackedWidget->addWidget(nextButton);
nextButton->show();

=====================================================

When I do this, the button is visible but cannot be clicked.

I hope for help.
thank you.

Hi and welcome to the forums.

if possible you should use the new connect syntax as that tells if a connection cannot be made at compile time.
https://wiki.qt.io/New_Signal_Slot_Syntax

in any case,
the addwidget you are using is for adding new pages!
Is that what you want ? Its very odd to use a button as a page.

if you mean to insert into the existing pages,
then you can access that widget via
ui->page
or ui->page_2
etc
You can see names in the Designer.

But often you want such buttons outside of the page and under the stackedwidget as you want them always there.
