It is posible to update a QTablewidget row by row?
-
Hello good evening ,I am making a small application that obtains IP numbers from a network and display them in a QTablewidget .The problem that I am facing is that the IP numbers are displayed in the table all at the same time and I would like them to be displayed one by one as they are obtained ,can this be achieved with a QTablewidget ?

As @jsulm has said there ought be no problem. If you are not seeing updates that sounds like you might be blocking the Qt event loop? Do you perchance have code likewhile waitForAndGetAnIPNumberUntilNoMore() updateTableWidget();? That kind of approach, which we see from beginners, won't work as it does not allow event loop to be re-entered and hence the update to be shown. Instead you would see all updates in one go when the
whileloop finally exits.@JonB Hello, good morning, you are right, now I was able to solve the problem I had using QThread, thank you.

Sure, just add each IP as soon as you receive it. What exact problem do you have?
