NOW UPDATED
- Inserted the correct link to the Autocomplete code that works fine and
- reduced the code of my example.
I am trying to embed autocomplete solution in a new python program. The autocomplete tkinter (https://gist.github.com/uroshekic/11078820) code is working fine on itself, but once embedded in my code I keep running into a NameError issue. (NameError: Name Entry not defined) (Line 4). While if I run the code (from the inserted link) it works fine. What am I missing?
I tried numerous different approaches.... but seem to miss the cause of the problem.
This is what I have so far:
#
import tkinter as tk
import re
class AutocompleteEntry(Entry):
def __init__(self, autocompleteList, *args, **kwargs):
# Listbox length
if 'listboxLength' in kwargs:
self.listboxLength = kwargs['listboxLength']
del kwargs['listboxLength']
else:
self.listboxLength = 14
# Custom matches function
if 'matchesFunction' in kwargs:
self.matchesFunction = kwargs['matchesFunction']
del kwargs['matchesFunction']
else:
def matches(fieldValue, acListEntry):
pattern = re.compile('.*' + re.escape(fieldValue) + '.*', re.IGNORECASE)
return re.match(pattern, acListEntry)
self.matchesFunction = matches
Entry.__init__(self, *args, **kwargs)
self.focus()
self.autocompleteList = autocompleteList
self.var = self["textvariable"]
if self.var == '':
self.var = self["textvariable"] = StringVar()
self.var.trace('w', self.changed)
self.bind("<Return>", self.selection)
self.bind("<Right>", self.selection)
self.bind("<Up>", self.moveUp)
self.bind("<Down>", self.moveDown)
self.listboxUp = False
def changed(self, name, index, mode):
if self.var.get() == '':
if self.listboxUp:
self.listbox.destroy()
self.listboxUp = False
else:
words = self.comparison()
if words:
if not self.listboxUp:
self.listbox = Listbox(width=self["width"], height=self.listboxLength)
self.listbox.bind("<Return>", self.selection)
self.listbox.bind("<Button-1>", self.selection)
self.listbox.bind("<Right>", self.selection)
self.listbox.place(x=self.winfo_x(), y=self.winfo_y() + self.winfo_height())
self.listboxUp = True
self.listbox.delete(0, END)
for w in words:
self.listbox.insert(END,w)
else:
if self.listboxUp:
self.listbox.destroy()
self.listboxUp = False
def selection(self, event):
if self.listboxUp:
self.var.set(self.listbox.get(ACTIVE))
self.listbox.destroy()
self.listboxUp = False
self.icursor(END)
def moveUp(self, event):
if self.listboxUp:
if self.listbox.curselection() == ():
index = '0'
else:
index = self.listbox.curselection()[0]
if index != '0':
self.listbox.selection_clear(first=index)
index = str(int(index) - 1)
self.listbox.see(index) # Scroll!
self.listbox.selection_set(first=index)
self.listbox.activate(index)
def moveDown(self, event):
if self.listboxUp:
if self.listbox.curselection() == ():
index = '0'
else:
index = self.listbox.curselection()[0]
if index != END:
self.listbox.selection_clear(first=index)
index = str(int(index) + 1)
self.listbox.see(index) # Scroll!
self.listbox.selection_set(first=index)
self.listbox.activate(index)
def comparison(self):
return [ w for w in self.autocompleteList if self.matchesFunction(self.var.get(), w) ]
class Example(tk.Frame):
def __init__(self, parent):
tk.Frame.__init__(self, parent)
autocompleteList = [ 'Dora Lyons (7714)', 'Hannah Golden (6010)', 'Walker Burns (9390)', 'Dieter Pearson (6347)']
def matches(fieldValue, acListEntry):
pattern = re.compile(re.escape(fieldValue) + '.', re.IGNORECASE)
return re.match(pattern, acListEntry)
self.entry = AutocompleteEntry(autocompleteList, root, listboxLength=12, width=32, matchesFunction=matches).pack()
self.val1 = StringVar()
self.entry1 = tk.Entry(textvariable=val1).pack()
self.addrow = tk.Button(self,text="Test", width=12, command=self.addrow).pack(side='left')
def addrow(self):
print( self.entry.get() + ", " + self.val1.get() )
self.art.set("")
root = tk.Tk()
Example(root).pack(expand=False)
root.mainloop()
The error I get:
Traceback (most recent call last): File "D:\test6_stack.py", line 4, in class AutocompleteEntry(Entry): NameError: name 'Entry' is not defined
What is wrong with this line (line 4)
class AutocompleteEntry(Entry):
And why is it working fine when I run the code from the github code?
Thanks for your time and help. Still learning!
