问题 I use QSqlRelationalTableModel to extract data from database, and use tableView to show it. Now, when I update my database, how to update tableView automatically to show it? I know i need to use function dataChanged() to make this automatically, but i do not know how to use it? Any suggestion will be appreciated.

问题 I created a tableview and it works normally as intended. However, I would like to change the scrolling such a way where the user can only scroll one cell at a time so that, there is never a time where the cell is cut in half.. This is an example: http://imgur.com/ffmk0jP So basically i do not want the default scrolling.. i would like it to be scrolled one cell at a time to constantly remain with the view of the original state.. Is there a way? 回答1: how about this ?

问题 I have finally created a tableview that will be populated with a certain amount of options for the user to click. Ideally, I would like the user to click a row, which will display a image on a second controller depending on the choice the user makes. For instance, "photo1" would display 1 picture on Controller B, while "photo 2" would display a different picture on Controller B. What code can I implement into my existing table view code to send to the second controller? import UIKit class
