In Qtableview Column data Synchronize

n-2204

I have two Qtableviews ( Qstandarditemmodel) so is there a way i can make two column as synchronize .
Use case1: in table1 when user enter values in column 1 and 2 (x,y values ) then based on these in table2 column 3 (calculate theta ) calculation should happen.
Second if user enter data in table2 column3 (enteres theta ) then based on this in table1 column 1 and 2 (cal x, y) data should update
if i use datachange signal then it will be very slow i guess! or as data will be change in both the tables
I have tables with 7 rows & 10 columns .
How can i do this ??

Hi,

If properly used, there should be no issue with dataChanged.

Why do you need two different models for that ?

ok. so if using datachange i can only mention signal for one table , i need to update for both the table datachange, user can enter data in any table
my mistake,actually i have 2 tables with diff columns

If you have multiple tables you will need each one to have its own dataChanged slot connected. If you need one table's data to alter another table's data it will need to know the instance of the other table to call setData() on.
