The use of processEvents() implies in most cases a bad design. If you have a heavy task, do not execute it in the main thread, execute it in another thread and send the necessary data to the main thread by means of signals or with QMetaObject::invokeMethod() (this last option will be used since it is not necessary so much connection).
On the other hand you should only add the stylesheet once, if there are new widgets they will take as a basis the stylesheet.

Hmm, seems like it doesnt work completly. Threading works, but when i callsql_querymethod it works, then it closes program with pycharm infoProcess finished with exit code -1073740791 (0xC0000409)It seems that the problem is with writing to the table?

I found and corrected it:self.tablewidget.insertRow(self.tablewidget.rowCount())But got only first column, the rest is empty. Errors:QBasicTimer::start: QBasicTimer can only be used with threads started with QThread QBasicTimer::start: QBasicTimer can only be used with threads started with QThread

The use of processEvents() implies in most cases a bad design. If you have a heavy task, do not execute it in the main thread, execute it in another thread and send the necessary data to the main thread by means of signals or with QMetaObject::invokeMethod() (this last option will be used since it is not necessary so much connection).
On the other hand you should only add the stylesheet once, if there are new widgets they will take as a basis the stylesheet.

Hmm, seems like it doesnt work completly. Threading works, but when i callsql_querymethod it works, then it closes program with pycharm infoProcess finished with exit code -1073740791 (0xC0000409)It seems that the problem is with writing to the table? During my main thread, clicking anything, it stops working sql_query?
