问题 I have a QTableWidget that when a row is clicked, it selects all cells in that row. I am trying to add a "copy" functionality so that I can ^ctrl-c when row(s) are selected and paste into a text editor. However, with my current code, once i ^ctrl-c a row, the line that I copied keeps getting copied. I have implemented a print statement in my method "read_clipboard" to see whether or not the line copied was read, and this is how I found out that the line keeps getting copied as if in an
