@the_ please help me

[the_]

As far as I can see you are asking this question again and again and again. If you use the search function in this forum you could find an answer

here for example (you did post in there too)

Please don't post the same question multiple times! It's shows disrespect to the people trying to help you on their own time. Stick to your original thread and provide more information, or ask additional related questions there.
Consider yourself warned.

@the_ how to use this code?

'''
QString queryStr = model->query().executedQuery();
model->clear();
model->query().clear();
model->setQuery(queryStr);

with this code? because this is the way i refresh a table is this bad?

@the_ IS THIS CODE OKAY? IF I WANT TO REFRESH A TABLE EVERY 3 OR MORE SECONDS?

import sys
import time
import os

x = 0
while x != 3:
x+=1
print (x)
#
'''
AND THE FUNCTION HERE TO REFRESH EVERY 3 OR MORE SECONDS?
'''
#
time.sleep(2)
if x >= 3:
x = 0

[the_]

Take a look at QTimer

@the_ how to translate this in python?

QString queryStr = model->query().executedQuery();
model->clear();
model->query().clear();
model->setQuery(queryStr);

and what is model?

[BjornW]

This thread must be a joke :/

[A Former User]

@BjornW for you it is. Maybe your an expert in coding that's why you are so boastful i am asking because i want to understand what i ask not to tell a joke

don't you worry next time i will try to ask "How to handle Overconfident people"

[the_]

Model is the QSqlQueryModel of your QTableView
