Change Active Window

[TonyInSoMD]

I have 2 windows open. I want to programmiticaly make one window be on top and have focus from the other window. I'm calling

window->setWindowState(Qt::WindowActive);
window->setFocus();

window->setWindowState(Qt::WindowActive);
window->setFocus();

To copy to clipboard, switch view to plain text mode 

but the window I'm calling it from stays in focus. Am I doing something wrong? They are both a QMainWindow
