[d4rc]

I need restart the application, i need know how do this. Exist a function to restart e.g "restart()"?


I use QT and I like it

What caused it to stop?

[d4rc]

I launch a dialog asking if he want a fullscreen or maximized and this save in bd a bool, and i need restart to pass again in main.cpp that read this bool

[JD2000]

Will restarting the app work?

I think that all you need to do is use

void QWidget::setWindowState ( Qt::WindowStates  windowState )

void QWidget::setWindowState ( Qt::WindowStates  windowState )

To copy to clipboard, switch view to plain text mode 

with

Qt::WindowFullScreen

Qt::WindowFullScreen

To copy to clipboard, switch view to plain text mode 

or whatever

Well then you don't need a restart! just create a private slot which reacts on the user decision and change to full screen of maximized. E.g.:

void MyMainWindow::changeScreenState(bool fullscreen)
{
  if (fullscreen)
    showFullScreen();
  else
    showMaximized();
}

void MyMainWindow::changeScreenState(bool fullscreen)
{
  if (fullscreen)
    showFullScreen();
  else
    showMaximized();
}

To copy to clipboard, switch view to plain text mode

hmm, i need something to restart this aplication, to pass again in main.cpp

Why does main.cpp need to know? Your main widget (perhaps mainWindow.cpp) can just be sent a signal.

how i call the mainWindow, give me error...

Are you asking how to send a signal from the dialog to the widget/window?

If so try reading the official documentation http://doc.trolltech.com/4.6/signalsandslots.html
