For the moment I do not test it on Linux. It seems that Linux 
distribution does not have necessarly a clipboard utility.


I will try it on Linux and if I find a solution I'll put it here.

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.

Remember that in Linux, unless you have something like klipper, when the app 
setting the clipboard exits, the clipboard empties.

sys.exit(app.exec_()) doesn't work. If the clipboard is empty when the program exits, I 
will do without PyQt so as to have a universal clipboard.


Thanks a lot because now I knows how to use clipboard in a real program..

Demetrius Cassidy a écrit :

The clipboard will empty when your program exits. Afaik this is normal
behavior with Qt and clipboard access. 


I know if I use wxWindows the text in the clipboard stays even if I close my
app, however I am not sure if it's possible to do this in Qt.

And use sys.exit(app.exec_()) instead.

[PyQt] Searching for a very small scprit using CLIPBOARD

2009-04-25 Thread projetmbc 

Hello,
here is an example for using the clipboard of Tkinter :

from Tkinter import *
root = Tk()
root.clipboard_clear()
root.clipboard_append('A text in the clipboard...')
root.withdraw()


I would like to do the same with PyQt. Is it possible ?

Christophe.

PS : if someone knows a Python script which is an universal ClipBoard 
(ie which works on Unix and Windows), it would be better. The purpose is 
just to send text.
