The error message you mentioned suggests that you are trying to convert a QTableWidgetItem object to a QString object, which is not directly possible because they are different types.
If you want to access the text of a QTableWidgetItem, you can use the text() function. Here’s an example of how to retrieve the text from a QTableWidgetItem and convert it to a QString:
QTableWidgetItem* item = new QTableWidgetItem("Hello");
QString text = item->text();
In this example, item is a pointer to a QTableWidgetItem containing the text “Hello”. We call the text() function on the item to retrieve its text content, and then assign it to a QString variable called text.
Make sure you include the necessary header files for QTableWidgetItem and QString in your code as well:
#include <QTableWidgetItem>
#include <QString>
Remember, QTableWidgetItem represents an item in a QTableWidget, while QString represents a string of characters.
