问题
To start, I've already looked at ekhumoro's code on a nearly similar subject Here. However, when I attempt to implement this code, I am getting a different result. Instead of copying and pasting all the I selected, it only copies the first cell of the selected row or rows respectively. I need users to be able to select multiple rows or columns and paste those values in either excel or notepad. Any ideas?
GUI:
Code:
from PyQt4 import QtCore, QtGui, QtSql
import sys
import sqlite3
import time
import csv
import Search # This file holds our MainWindow and all design related things
# it also keeps events etc that we defined in Qt Designer
import os
try:
from PyQt4.QtCore import QString
except ImportError:
QString = str
class TableEditor(QtGui.QMainWindow, Search.Search_MainWindow):
def __init__(self, tableName, parent=None):
# Explaining super is out of the scope of this article
# So please google it if you're not familar with it
# Simple reason why we use it here is that it allows us to
# access variables, methods etc in the design.py file
super(self.__class__, self).__init__()
self.setupUi(self) # This is defined in design.py file automatically
# It sets up layout and widgets that are defined
self.model = QtSql.QSqlTableModel(self)
self.model.setTable('CAUTI')

回答1:
Your implementation is broken in several ways, so the code you copied never gets executed. As a result, the table's built-in copy function is used, which does not handle multiple selected items.
My original code for copying multiple table items is here. I think you should be able to get your example working by changing the following lines:
from PyQt4 import QtCore, QtGui, QtSql
# fix imports
import sys, io
...
class TableEditor(QtGui.QMainWindow, Search.Search_MainWindow):
def __init__(self, tableName, parent=None):
# do not ever use self.__class__ here
super(TableEditor, self).__init__()
...
# install event-filter properly
self.tableView.installEventFilter(self)
def eventFilter(self, source, event):
...
# call super properly
return super(TableEditor, self).eventFilter(source, event)
Obviously, I cannot run your actual example code, so there may be other errors that I haven't spotted.

This is much faster :
def copySelection(self):
clipboardString = StringIO()
selectedIndexes = self.ui.tableView.selectedIndexes()
if selectedIndexes:
countList = len(selectedIndexes)
for r in range(countList):
current = selectedIndexes[r]
displayText = current.data(QtCore.Qt.DisplayRole)
if r+1 < countList:
next_ = selectedIndexes[r+1]
if next_.row() != current.row():
displayText += ("\n")
else:
displayText += ("\t")
clipboardString.write(displayText)
pyperclip.copy(clipboardString.getvalue())
