Hello,
My application wants to provide 2 types of clipboard data;
* Filename uri list,
* Filename list as text.
The clipboard targets are:
clipboard_targets = [
('x-special/gnome-copied-files',0,0),
("text/uri-list",0,0),
("UTF8_STRING",0,0)]
I use the clipboard.set_with_data(..) function to set the targets and a
callback function that hands over the data.
clipboard.set_with_data(clipboard_targets, clipboard_get_data_cb,
clipboard_clear_data_cb, lst)
The problem is in the clipboard_get_data_cb(...) function. the TARGET
list is always null/none. So the function does not know what type of
data the receiver wants/can handle.
selectiondata.targets_include_uri() --> Always none
selectiondata.targets_include_image(True) --> Always none
selectiondata.targets_include_text() --> Always none
I just set the clipboard_targets in the above call, so why are these
values None?
I have tested this by running the enclosed test.py and doing "Paste"
from Gedit, Nautilus, terminal window and The Gimp. These should handle
all the aforementioned target types.
Here is a complete test code:
http://www.futuredesktop.com/tmp/clipboard-test.zip
Some beginning lines of the code:
def clipboard_copy_data(file_lst):
clipboard = gtk.clipboard_get()
clipboard_targets = [('x-special/gnome-copied-files',0,0),
("text/uri-list",0,0),
("UTF8_STRING",0,0)]
# Probably not necessary, but
import copy
lst = copy.deepcopy(file_lst)
clipboard.set_can_store(clipboard_targets)
ret = clipboard.set_with_data(clipboard_targets,
clipboard_get_data_cb, clipboard_clear_data_cb, lst)
return ret
def clipboard_get_data_cb(clipboard, selectiondata, info, userdata):
print "info=", info
file_lst = userdata
print "clipboard_get_data_cb, file_lst=", file_lst
# Why are these targets always null?
print "targets=", selectiondata.get_targets()
print "targets_include_uri=", selectiondata.targets_include_uri()
print "targets_include_image=",
selectiondata.targets_include_image(True)
print " targets_include_text=", selectiondata.targets_include_text()
...
...
It will also provide Pixbuf as clipboard data, but I can use these calls
directly:
clipboard=gtk.clipboard_get()
pb = gtk.gdk.pixbuf_new_from_file(filename)
clipboard.set_image(pb)

My development environ is Ubuntu 10.04 and the GNOME-desktop.
PS. the final application will be this
