I am trying to implement a simple validator for a QLineEdit. To do this
you should inherit from QtGui.QValidator and overload the method
validate(). The validate method should then return either of the flags:
QtGui.QValidator.Invalid
QtGui.QValidator.Intermediate
QtGui.QValidator.Acceptable
Below is included a simple example that always returns
QtGui.QValidator.Acceptable. Nevertheless, the programs raises the error
TypeError: invalid result type from Validator.validate()
no matter what you type in the line edit.
Any suggestions?
Best, Mads
import sys
from PyQt4 import QtGui
class Validator(QtGui.QValidator):
def __init__(self, parent=None):
QtGui.QValidator.__init__(self, parent)
def validate(self, string, pos):
return QtGui.QValidator.Acceptable
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
line_edit = QtGui.QLineEdit()
line_edit.setValidator(Validator())
line_edit.show()
sys.exit(app.exec_())
