Crash application after delete window

[anda_skoa]

Hmm, that is indeed not a lot to go on.

Do you need to delete the window?

I.e. it is not being deleted when the user closes it, so I am wondering why you need to delete it when you are closing it from code.

I`m find solution. I`m delete window not after close() are before show()

if (window != 0) {
  delete window;
  window = 0;
}
 
window = new QDeclarativeView();
window->show();

if (window != 0) {
  delete window;
  window = 0;
}

window = new QDeclarativeView();
window->show();

To copy to clipboard, switch view to plain text mode

you can call delete window even without the check for != 0 first,
Delete is defined to do nothing on a null pointer.
