在QLineEdit对象中,我可以像这样设置一个RegExp验证器:
validator = QtGui.QRegExpValidator(QtCore.QRegExp("\d{11}"), lineedit)
lineedit.setValidator(validator)
如何在QTableView上编辑单元格时设置类似的验证器?

通过继承QStyledItemDelegate并重新实现createEditor方法:
class ValidatedItemDelegate(QtGui.QStyledItemDelegate):
def createEditor(self, widget, option, index):
if not index.isValid():
return 0
if index.column() == 0: #only on the cells in the first column
editor = QtGui.QLineEdit(widget)
validator = QtGui.QRegExpValidator(QtCore.QRegExp("\d{11}"), editor)
editor.setValidator(validator)
return editor
return super(ValidatedItemDelegate, self).createEditor(widget, option, index)
然后你可以像这样设置验证器:
tableview.setItemDelegate(ValidatedItemDelegate())
