Hi all experts,
I'm new in Python and GTK. I have a trouble and wondering if anybody
can help me:
I create a button, connect to a FileChooserDialog. When I click the
button, I can choose a file and print it's name.
But, if I click 'cancel' for the first time, then I click the button
again, it crashed..
Can anyone give me a hand? Thank you!
Here's my codes:
********************************
import pygtk
pygtk.require('2.0')
import gtk
# Check for new pygtk: this is new class in PyGtk 2.4
if gtk.pygtk_version < (2,3,90):
print "PyGtk 2.3.90 or later required for this example"
raise SystemExit
class choosefile:
dialog = gtk.FileChooserDialog("Open..",
None,
gtk.FILE_CHOOSER_ACTION_OPEN,
(gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL,
gtk.STOCK_OPEN, gtk.RESPONSE_OK))
dialog.set_default_response(gtk.RESPONSE_OK)
class mainwindow:
def __init__(self):
window = self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
window.connect("destroy",lambda w: gtk.main_quit())
window.set_title("gtk test")
button = gtk.Button(label="run")
button.connect("clicked",self.run)
window.add(button)
button.show()
window.show()
def run(self,item):
fl = choosefile()
response = fl.dialog.run()
if response == gtk.RESPONSE_OK:
filename = fl.dialog.get_filename()
elif response == gtk.RESPONSE_CANCEL:
print 'Closed, no files selected'
fl.dialog.destroy()
print filename
wd = mainwindow()
gtk.main()
