Hello. I'm trying to make an entry completion field and having no luck.
The relevant part of the glade file is
<object class="GtkEntry" id="student_change">
<property name="visible">True</property>
<property name="can_focus">True</property>
<property name="invisible_char">●</property>
<property name="width_chars">25</property>
<signal name="activate"
handler="student_change_activate_cb"/>
</object>
and then my python is:
class appGUI(gobject.GObject):
def __init__(self):
gobject.GObject.__init__(self)
self.builder = gtk.Builder()
self.builder.add_from_file('gradebook.glade')
self.window = self.builder.get_object('winapp')
self.builder.connect_signals(self)
self.names = gtk.ListStore(gobject.TYPE_STRING)
query = "SELECT * from students"
db = sqlite3.connect('gradebook.db')
cursor = db.cursor()
cursor.execute(query)
students = cursor.fetchall()
for student in students:
self.names.append([student[1]])
print student[1]
cursor.close()
# Don't know if I understand correctly, but....
# Don't you need a student_change widget before using it?
# I could it see one created earlier, ..... i.e.
self.student_change = self.builder.get_object('student_change')
self.student_change.set_model(list)
<-------------PROBLEM
self.student_change.set_text_column(0)
completion = gtk.EntryCompletion()
completion.set_model(list)
completion.set_minimum_key_length(1)
completion.set_text_column(0)
self.student_change.set_text_column(0)
self.student_change.child.set_completion(completion)
def match_cb(self, completion, model, iter):
print model[iter][0], 'was selected'
return
def student_change_activate_cb(self, entry):
text = entry.get_text()
if text:
if text not in [row[0] for row in self.names]:
self.names.append([text])
entry.set_text('')
return
When I run my code, I get:
Traceback (most recent call last):
File "gradebook.py", line 67, in<module>
app = appGUI()
File "gradebook.py", line 34, in __init__
self.student_change.set_model(list)
AttributeError: 'appGUI' object has no attribute 'student_change'
Line 34 is marked above with PROBLEM. I've found quite a few examples
on hard coding entrycompletion with the gtk, but nothing with glade.
And sucking like I do at programming, I can not for the life of me
figure this out. Any help, even links to relevant examples, would be
super appreciated.
