pyforms的密码字段？

Question

我的UI用pyforms编写。

我如何实现密码字段？ （例如，而不是“ P @ ssW0rd”，它将显示“ ********”）。

我发现我可以利用QLineEdit.EchoMode，但是不确定如何实现。

提前感谢！

您可以在项目文件夹中将以下模块作为ControlPasswordText.py添加：

from pysettings import conf
from pyforms.Controls import ControlText

from PyQt4.QtGui import QLineEdit

class ControlPasswordText(ControlText):
    def __init__(self, *args, **kwargs):
        super(ControlPasswordText, self).__init__(*args, **kwargs)
        self.form.lineEdit.setEchoMode(QLineEdit.Password)

这是您将如何使用它：

import pyforms
from   pyforms          import BaseWidget
from   pyforms.Controls import ControlText
from   pyforms.Controls import ControlButton

# Importing the module here
from ControlPasswordText import ControlPasswordText

class SimpleExample1(BaseWidget):

    def __init__(self):
        super(SimpleExample1,self).__init__('Simple example 1')

        #Definition of the forms fields
        self._username     = ControlText('Username')
        # Using the password class
        self._password    = ControlPasswordText('Password')


#Execute the application
if __name__ == "__main__":   pyforms.startApp( SimpleExample1 )

结果：

Pyforms还包括一个密码框。您也可以使用self._password = ControlPassword('Password')

简单地说：

import pyforms
from pyforms.basewidget import BaseWidget
from pyforms.controls import ControlText
from pyforms.controls import ControlButton
from pyforms.controls import ControlPassword


class Login(BaseWidget):

    def __init__(self):
        super(Login,self).__init__('Simple example 1')

        #Definition of the forms fields
        self._username  = ControlText('Username', 'Default value')
        self._password = ControlPassword('Password')

        self._button     = ControlButton('Login')
        self._button.value = self.__buttonAction #Define button action

    def __buttonAction(self):
        """Button action event"""
        username = self._username.value
        password = self._password.value
        credentials = (username, password)
        return credentials

#Execute the application
if __name__ == "__main__":
    pyforms.start_app( Login )
