Hi Aaron,

Your example works well. However, when I try to paste plain text to the
paste app with my set_clipboard function, it freezes. It does work with
PyQt4, though.

I don't know in which way to manage the event loop so that it allows me to
run the function in an interactive way (ie without entering the qt event
loop forever) and if possible also inside ipython qtconsole (spyder) when
ran with pyside. I have tried something like this (with quite some
tweaking) to no avail:



def start_app():
    app = QtCore.QCoreApplication.instance()
    if app is None:
        print "app"
        app = QtGui.QApplication([])
    return app

def exec_app(app):
    try:
        from IPython.lib.guisupport import start_event_loop_qt4
        start_event_loop_qt4(app)
    except ImportError:
        app.exec_()


def run_in_qt (f, *args, **kwargs):
    def _f(*args, **kwargs):
        app = start_app()
        def _exe():
            f(*args, **kwargs)
            app.quit()
        QtCore.QTimer.singleShot(1, _exe)
        exec_app(app)
    return _f


@run_in_qt
def set_clipboard(content, mime = 'text/plain'):
    #app=QtGui.QApplication.instance() # checks if QApplication already
exists
    #if not app: # create QApplication if it doesnt exist
    #    app = QtGui.QApplication(sys.argv)

    mymime = QtCore.QMimeData()
    mymime.setData(mime, QtCore.QByteArray(content.encode('utf-8')))
    app = start_app()
    clipboard = app.clipboard()
    clipboard.setMimeData(mymime)


The function start_event_loop_qt4(app) basically exec_'s the app only if
none is already running. I can't understand what does pyside do with the
registers in which it stores the clipboard. For example, I can paste after
I close your copy app, but it's not the same here...
