However, columnCount() will have an effect on rows that give a number that is less than this number, in that columns less than this number will not be populated. I found that I should use setItem() function to add data to a QTableWidget and give it the row and column number and a QTableWidgetItem. The QTreeWidget class allows you to create a tree view widget that consists of items. It is not good to access the model directly from another thread since the QObjects are not thread-safe, instead it creates a QObject that sends the data to the main thread through signals, in this case for a simple operation I created the slot update_item that receives the row, column and data. By joining our free community you will have I would like to know if it is possible to hide a column of a QTableWidget, without using the QTableView ?
