Я хотел бы проверить выбор пользователя для имени папки в диалоге gtk.FileChooser при создании новой папки.
Я попытался подключиться к диалогу «ответ», но уже слишком поздно, новая папка будет записана на диск.
Есть ли способ достичь этого, а затем проверить папку после ее записи на диск?
Спасибо Марку ... вот код, который я использую:
import gtk
def _newFolderDialog(currentFolder=None):
newDialog = gtk.FileChooserDialog(
title="Create new folder", parent=None,
action=gtk.FILE_CHOOSER_ACTION_CREATE_FOLDER,
buttons= (gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL), backend=None)
newButton = newDialog.add_button(gtk.STOCK_NEW, gtk.RESPONSE_OK)
if currentFolder is not None:
newDialog.set_current_folder(currentFolder)
newButton.connect("pressed", validateChoice, newDialog)
response = newDialog.run()
if response == gtk.RESPONSE_OK:
newFolder = newDialog.get_filename()
newDialog.destroy()
return newFolder
elif response == 1: # Validation was not satisfied
msg = gtk.MessageDialog(parent=None, flags=gtk.DIALOG_MODAL,
type=gtk.MESSAGE_ERROR, buttons=gtk.BUTTONS_OK,
message_format="Try again!")
msg.run()
msg.destroy()
current_folder = newDialog.get_current_folder()
newDialog.destroy()
return _newFolderDialog(current_folder)
elif response == 2: # Ok button was pressed, but with no entry
current_folder = newDialog.get_current_folder()
newDialog.destroy()
return _newFolderDialog(current_folder)
elif response == gtk.RESPONSE_CANCEL:
newDialog.destroy()
return None
def validateChoice(button, dialog):
newFolder = dialog.get_filename()
if newFolder is None: # The cursor was in the empty text entry box
dialog.response(2)
else:
# If cursor is selecting a folder, lets unselect it, we are intereste
# in the value in the entry text box.
dialog.unselect_filename(newFolder)
newFolder = dialog.get_filename()
if newFolder is None: # A folder was selected but empty text entry box
dialog.response(2)
## do some validation, in this case the folder has to start with "/home"
elif not newFolder.startswith("/home"):
dialog.response(1)
else:
dialog.response(gtk.RESPONSE_OK)
newFolder = _newFolderDialog()
print newFolder
