We can select multiple items(partial rows and partial columns) from QTableView using self.tableView.setSelectionMode(QAbstractItemView.ExtendedSelection), but after selecting some rows and columns(partial and partial) if I do CTRL+C and paste it in notepad it only pastes one item(one value from the tableView)?
My Code:
tab_table_view = QtGui.QWidget()
self.Tab.insertTab(0, tab_table_view, self.File_Name)
self.tableView = QtGui.QTableView(tab_table_view)
self.tableView.setGeometry(QtCore.QRect(0, 0, 721, 571))
self.model = QtGui.QStandardItemModel(self)
self.model.setSortRole(QtCore.Qt.UserRole)
self.tableView.setModel(self.model)
self.tableView.setSelectionMode(QAbstractItemView.ExtendedSelection) '''this helps for selecting multiple items but not able to copy and paste multiple values to a text/ excel (it only copies single value)'''
我们如何复制并粘贴多个项目？
self.tableView.installEventFilters(self)
现在，添加事件过滤器：
def eventFilter(self, source, event):
if (event.type() == QtCore.QEvent.KeyPress and
event.matches(QtGui.QKeySequence.Copy)):
self.copySelection()
return True
return super(Window, self).eventFilter(source, event)
复制功能：
def copySelection(self):
selection = self.tableView.selectedIndexes()
if selection:
rows = sorted(index.row() for index in selection)
columns = sorted(index.column() for index in selection)
rowcount = rows[-1] - rows[0] + 1
colcount = columns[-1] - columns[0] + 1
table = [[''] * colcount for _ in range(rowcount)]
for index in selection:
row = index.row() - rows[0]
column = index.column() - columns[0]
table[row][column] = index.data()
stream = io.StringIO()
csv.writer(stream).writerows(table)
QtGui.qApp.clipboard().setText(stream.getvalue())
