问题 The code below creates a single dialog with a QTableView view. On left-click the onLeftClick function gets an QModelIndex index . This QModelIndex is used later to print the row and column numbers of the left-clicked cell. How to get the QModelIndex index of the cell that was right-clicked? from PyQt5.QtGui import * from PyQt5.QtWidgets import * from PyQt5.QtCore import * app = QApplication([]) class Dialog(QDialog): def __init__(self, parent=None): super(Dialog, self).__init__(parent) self

问题 I have a small issue with proper resizing of rows in my tableview. I have a vertical header and no horizontal header. I tried: self.Popup.table.setModel(notesTableModel(datainput)) self.Popup.table.horizontalHeader().setVisible(False) self.Popup.table.verticalHeader().setFixedWidth(200) for n in xrange(self.Popup.table.model().columnCount()): self.Popup.table.setColumnWidth(n,150) And this works fine, but when I try: for n in xrange(self.Popup.table.model().rowCount()): self.Popup.table
