qstackedwidget timeout

WhatIf

Hi,

I created a qstackedwidget (3 pages) using qt designer. My goal is page 1 leads the user to page3. When the user clicks a button on page 1, page 2 will show a message for 10-15 seconds then the user is redirected to page 3. I can't figure out how to implement it nor can I find an example online I can study.

Would appreciate your assistance!

Hi,

You can use QTimer for that kind of task. What precisely do you have in mind ?

Hi
you can use a timer which you connect to your slot.
When you press button 1, you start timer and switch to page 2
(showing the message)
then when timer fires its timeout() signal, to your slot, then
you simply go to page 3.

I'm just starting to learn Qt and get involved in C++ programming again. I followed your advise to the best of my ability but ran through an error.

In mainwindow.h I added void move2page3();

private slots:
    void on_pushButton_clicked();
    void move2page3();

in mainwindow.cpp I added

void MainWindow::on_pushButton_clicked()
{
    QTimer::singleShot(200, this, SLOT(move2page3()));

    ui->stackedWidget->setCurrentIndex(1);
}

void MainWindow::move2page3()
{
    ui->stackedWidget->setCurrentIndex(2);
}

When I try to run the app, I get the following error:

C:\3pages\mainwindow.cpp:-1: In member function 'void MainWindow::on_pushButton_clicked()':

C:\3pages\mainwindow.cpp:18: error: incomplete type 'QTimer' used in nested name specifier
QTimer::singleShot(200, this, SLOT(move2page3()));
^

First, am I following your advice or did I miss anything?
Second, what am I doing wrong?

Okay, I was missing the #include <QTimer> in mainwindow.cpp and mainwindow.h

It's now working, thanks :)

Did I implement your advice the way you had in mind? Do you have any feedback?

Hi
Yes it was as i thought of.
Even better actually as you found singleShot :)
Only thing that I wondered was
the singleShot(200) as 200 is very fast :)
