Hi i'm pretty new with python and kivy , im trying to do a simple "to do" app.. My code looks horrible, i know, and im sorry for that..
I have a table in sqlite3 with some information stored in it. I would like to call a function that query this table on app start up. I can't figure out how to make it work.. Here is my code
Python:
import sqlite3

some pieces of code are unused don't worry about it.
Function i need to call is reloadSession that query table and then with the information retrieved create n buttons...
As you can see, in the SmsButton class(in KV) call that function(ON_PRESS), i need to do the same thing but automatically on app start up... How can i do that??
Sorry for my bad english and coding.. Im new, im trying a lot of stuff, i would appreciate your help.
Thank you.
Yvan.
EDIT: removed unused code
EDIT : #bj0
thanks for the tips.. i've tryied to use build function in alla the way i know. but it doesnt work ...i get this error
("'Test' object has no attribute 'links_grid'",)
the code im using now is this..
class Test(App):
def build(self):
try:
con = sqlite3.connect('localdb.db')
cur = con.cursor()
cur.execute("select * from localtb")
data = cur.fetchall()
con.close()
for x in data:
reload_Element = str(x[0])
if x[1] == 0:
print "in if: ", x[1]
link_button = LinkButton(text = reload_Element,background_color = [83,0,0,1])
else:
print "in else: ", x[1]
link_button = LinkButton(text = reload_Element,background_color = [0,83,0,1])
self.links_grid.add_widget(link_button)
except Exception as inst:
print inst.args
print "non va"
obviously Test class has no links_grid attribute.. but how can i solve this problem ?
Thanks again

While creating a tkinter GUI application, I created a window with a button to close the program and terminate the script, but when I used it, the program did close but the script was still running in the background and I was unable to start the program again.
I have tried several different functions to close the program, but nothing has worked. Here are some of my attempts:

I have a treeview widget that displays a simple list from a table.
I want to automatically highlight one of the items on the list. (this works perfectly).
Now, I want this item to automatically receive a mouse click (without any action from the user). according to the documentation, use the command Rec_list.event_generate ('<ButtonRelease-1>' .format (button-1), when = "now")
but without results.

how to activate a mouse click without user intervention?
Thank you for your time, have good day
Auto Selection Item
This is a slightly nonprofessional route, but using a library such as py-game can automatically click or select with the mouse, you would have to take in to account screen resolution though. You can also try to see if there is a property to auto-select, check the Tkinter reference guide for help, Link 1
i find solution
import tkinter as tk
import tkinter.ttk as ttk
import time
tree = ttk.Treeview()
for i in range(10):
iid = tree.insert('', 'end', text=i)
tree.pack()
def event_test(iid):
t['text'] = iid
print("iid", iid)
def move_bottom():
iid = tree.get_children('')[-1]
time.sleep(1)
if iid != tree.focus():
iid = tree.get_children('')[5]
tree.focus(iid)
tree.selection_set(iid)
print("iid", iid)
tree.event_add('<<Declenche>>', '<ButtonRelease-1>')
tree.after(1000, lambda: tree.event_generate('<<Declenche>>'))
tree.bind('<<Declenche>>', event_test(iid))
t = tk.Label()
t.pack()
tk.Button(text='move', command=move_bottom).pack()
tree.mainloop()
To automate the selection I found this solution: in insert for loop where the data is from a table of a database, I use 1 particular db-data as value (better an unique id). I get the iid with get_children method using the loop index. In the for I insert data into a dictionary where the key is the iid and the value is the value (unique data) form the db.
If the goal to change data in the row and send that back into the database, you can make a query selection to find the first unchanged row, and select only the unique id, unique data of this row (or use the main autoincremented rowid). Use that id for having the iid of that row, than make focus and selection with that iid. After the binding that selection to an event you can run that calling event to run your method without clicking on any row.
def calling(event):
selectedRow = tree.item(tree.focus())
datas = selectedRow['values']
var1 = datas[0]
var2 = datas[1]
yourMethod(var1, var2)
def keyGetter(val, lib):
for key, value in lib.items():
if val == value:
return key
return "key doesn't exist"
index = 0
iidLibrary = dict()
for row in rows:
tree.insert("", index, values = (row[0], row[1], row[2))
iid = tree.get_children()[index]
iidLibrary[iid] = row[3]
curs.execute(
"SELECT id_of_row FROM table WHERE something=? ORDER BY rowid ASC LIMIT 1", (variable, )
firstUnclosed = curs.fetchall()
iidActual = keyGetter(firstUnclosed[0][0], iidLibrary)
tree.focus(iidActual)
tree.selection_set(iidActual)
tree.bind('<<TreeviewSelect>>', calling)

This is the error thrown by my program. Can anyone help me to resolve this error?
I think the error is in receberl function.
File "-------", line 1558, in __call__
return self.func(*args)
File "------", line 17, in receberl
ler_dados(Senha)
File "------", line 69, in ler_dados
for row in c.execute(buscar_dados, (valorbusca,)):
sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 2, and there are 1 supplied.
The error message you are getting is pretty clear: your SELECT query binds two parameters, but your code only specifies one of them. To fix, first change your call to ler_dados() to pass in both the username and password:
def receberl():
global Nome, Senha
Nome = entradalogin.get()
Senha = entradasenha.get()
ler_dados(Nome, Senha)
# ... etc.
And then in your query bind both the username and password:
def ler_dados(username, valorbusca):
global row
global x
buscar_dados = "SELECT * FROM Registro WHERE Nome = ? AND Senha = ?"
for row in c.execute(buscar_dados, (username, valorbusca,)):
if Nome and Senha in row:
x = True
You need to provide 2 arguments for this query :
buscar_dados = "SELECT * FROM Registro WHERE Nome = ? AND Senha = ?"
When you call ler_dados(Senha) in the function receberl, looks like Nome is missing.
You should use something like : ler_dados(Nome, Senha) first
and then change the method ler_dados to :
def ler_dados (nome, senha):
global row
global x
buscar_dados = "SELECT * FROM Registro WHERE Nome = ? AND Senha = ?"
for row in c.execute(buscar_dados, (nome, senha)):
if Nome and Senha in row:
x = True
