How to launch mainwindow from a dialog window?

[DanqueDynasty]

Ok, so the program starts out with a dialog window requesting information from the user to log on. How can I get the mainWindow to open from the dialog window. Thanks.

Off the top of my head, I would implement it like this.

Main.cpp
@
QApplication a(argc,argv);
MyMainWindow b;
return a.exec();
@

Note the missing b.show(); command.

Then, in the constructor for MyMainWindow,

@
MyOpenDialog *a = new MyOpenDialog();
a->exec();
this.show();
@

As long as MyOpenDialog is set as Application Modal, you won't process the this.show() until after the dialog has closed.

Edit: I should add, if you're all done with MyOpenDialog, you'll want to
@delete a;@ afterwards this.show();

Dear Keozon,

Would you mind to show in complete file MyMainWindow.cpp?
Thanks in advance.

bq. MyOpenDialog *a = new MyOpenDialog();
a->exec();
this.show();

i think the a->exec() should be followed by some check-up functions that call the .show() if log in was successful.

go for it !
