Reg: Open Parent window when push button clicked in child window

Vishva

Hi All,
I am new to QT and manage to make an application with 3 windows. I am able to navigate forward 1->2->3 or 1->3.
But if i wanna go back i.e from 3->1 window how do i do it??
How do i connect a pushbutton in 3rd window to show the 1st window.

Any help would be appreciated. I tried to search the forum but didnt succeed to find soln.

Hi,

This sounds like something where you can use "QWizard":http://qt-project.org/doc/qt-5.0/qtwidgets/qwizard.html

Hope it helps

When you navigate from 1 to 2 or 2 to 3 ,You close the current window .Don't close these windows, instead of closing them just hide them.
Solution : "use hide() in place of close()"

then you can navigate from 3 --->1 .

you can emit signals from each window to target window
so that you can call hide()/show() in the slots of respective windows

i also want the same thing but as i used the show()/hide then it will hide the main window but it will not showing new window.
the new window which i want to show that should be having diff .cpp , .h file and different .ui
so as we press the push button of main window that new window should open ..
please help me out..
thanks in advance

Hello ndv472.

Can you show your code .

ndv472

yes sir,
i have used 2 3 cases
1st case
void nn_adc_trial::on_pushButton_clicked()
{
QWidget *new_window=new QWidget ;
new_window->show();
hide ();
}
that will give me 1 new window but same of main window

as per your code definitely it will not show the mainwindow due to hide() but would show new window.

Make your own C++ Class(.cpp/.h) for New widget (inherits QWidget ) that you want to show.

Edited:- Try to give your code with proper indentation on the forum so it can be readable.

Why dont you use stack concept in Qt, using push and pop for showing parent and child.
