subwindow mdi signal

[walito]

Thz for your help!!

Now understand! In the Signal/Slot Editor (In designer) I created the connection:

QObject::connect(actionNueva_ventana, SIGNAL(triggered()), vPrincipal, SLOT(actionNueva_ventana()));

QObject::connect(actionNueva_ventana, SIGNAL(triggered()), vPrincipal, SLOT(actionNueva_ventana()));

To copy to clipboard, switch view to plain text mode 

Now work.
Well thz, and attach project for future people need this example.

Bye bye
