Existing Window Call

[hasnatzaidi]

hi , I posted thread earlier regarding this problem but not solved.
Here Following code are call UI file in Main Project

void MainWindow::on_btn_screate_clicked()
{
// sessiondetail.ui is another UI file in same project
 Ui::sessiondetail ui;  
 QMainWindow *sessiondetail = new QMainWindow;
 ui.setupUi(QMainWindow *sessiondetail);
 
}

void MainWindow::on_btn_screate_clicked()
{
// sessiondetail.ui is another UI file in same project
 Ui::sessiondetail ui;  
 QMainWindow *sessiondetail = new QMainWindow;
 ui.setupUi(QMainWindow *sessiondetail);

}

To copy to clipboard, switch view to plain text mode 

And its output error is

mainwindow.cpp:462: error: expected primary-expression before '*' token

As a result which i want the sessiondetail.ui file must be displayed when click on button.
Can anyOne Plz Slove this problem
thanks to every one

The code is syntactically incorrect. The line "6" should read "ui.setupUi(sessiondetail);".

thanks Wysota, for doing this it can't generate error
but it also can't call UI file which i want, when click on button

[wysota]

Sure it can. But it will go out of scope immediately. Look at your code again - you created an object local to the function and can't expect it to last beneath the function.

thanks
it done with this code

void MainWindow::on_btn_screate_clicked()
{
 
Ui::sessiondetail ui;
QMainWindow *sessiondetail = new QMainWindow;
ui.setupUi(sessiondetail);
sessiondetail->show();
 
}

void MainWindow::on_btn_screate_clicked()
{

Ui::sessiondetail ui;
QMainWindow *sessiondetail = new QMainWindow;
ui.setupUi(sessiondetail);
sessiondetail->show();

}

To copy to clipboard, switch view to plain text mode 

but it display sessiondetail.ui file 2 times,
what reason behind it
