We ran into a similar situation where we wanted to ensure that a QPixmap that is copied into the clipboard stays after the application exits. Although as far as I know this should happen automatically when your Qt application exists, we had to do this use the following code manually before exiting our application.
# Send an event to the clipboard so that it copies the data over to the # clipboard instead of keeping a pointer to the data internally. This should # happen automatically on exit, but it appears that the mime type convertion # methods for Qt -> windows formats get unregistered before this event gets # processed. This caused a bug where we couldn't paste data after closing # because there was not a conversion method. The magic function on Windows that # needs to be called to do this copy is OleFlushClipboard. from PyQt4 import QtGui, QtCore clipboard = QtGui.QApplication.clipboard() event = QtCore.QEvent(QtCore.QEvent.Clipboard) QtGui.QApplication.sendEvent(clipboard, event) The basic concept behind this is that by default copying something into the clipboard only copies a reference/pointer to the source application. Then when another application wants to paste the data from the clipboard it requests the data from the source application. Calling OleFlushClipboard [1] causes Windows to copy the real data into the clipboard instead of the reference. While this does cause a delay when copying images, it should not have any noticeable impact with strings. -Aron [1] http://msdn.microsoft.com/en-us/library/ms679707(VS.85).aspx On Sun, Apr 26, 2009 at 2:34 AM, projetmbc <projet...@club-internet.fr> wrote: > sys.exit(app.exec_()) doesn't work.
