Thanks for the links !

You have one table widget (or similar, actually presumably QTableView rather than QTableWidget since you have your own model) holding rows & columns from a SQL query. You say you want another table widget to show a column "computed" (at client side) from columns in the first one.

So why not create a second model whose data() method is overridden to perform the necessary computation and return the desired final string for Qt::DisplayRole using the index.row/column() (not just the index) as indexers into the SQL model's rows/columns?

Or, if you want to stick with your current usage of QTableWidget (not ideal that you use Python SQL calls and copy result set into that, but up to you), you could make your second one a QTableWidget too and use setData() to populate its rows/columns with the actual corresponding strings whenever the first one changes (more work depending on how often your data changes, but in your case it might only be during loaddata() when you populate if it does not change thereafter).

@esekyere after a very short search on google i got this :

loader = QUiLoader() file = QFile(":/forms/myform.ui") file.open(QFile.ReadOnly) myWidget = loader.load(file, self) file.close()

Note that I am able to configure and deploy using ndk-r9d with GCC 4.8, but debugging does not work at all on a Galaxy S6. Setting a breakpoint in main(), nothing is hit. Note that I am able to debug using Android Studio for a regular Java app on the device. This is the application output:
