一、一、API接口设置接口设置

比如我这段代码中的一些设置，设置文字、居中、禁止复制、LineEdit输入为password等等

import sys

from PyQt5.QtCore import Qt

from PyQt5.QtWidgets import QFrame

from PyQt5.QtWidgets import QPushButton

from PyQt5.QtWidgets import QGridLayout

from PyQt5.QtWidgets import QApplication

from View import interface

class MainWindow(QMainWindow):

def __init__(self):

super(MainWindow,self).__init__(None)

self.setWindowTitle("对金属腐蚀性试验仪")

self.initUI()

def initUI(self):

self.loginTxt.setText("admin")

self.loginTxt.setPlaceholderText("User Name")

self.loginTxt.setClearButtonEnabled(True)

self.pwdLabel = QLabel("密码：")

self.pwdLabel.setAlignment(Qt.AlignRight)

self.pwdTxt = QLineEdit()

self.pwdTxt.setContextMenuPolicy(Qt.NoContextMenu) #禁止复制粘贴

self.pwdTxt.setPlaceholderText("Password")

self.pwdTxt.setText("admin")

self.pwdTxt.setEchoMode(QLineEdit.Password)

self.headLabel.setStyleSheet("color:rgb(10,10,10,255);font-size:25px;font-weight:bold;font-family:Roman times;")

self.headLabel.setSizePolicy(QSizePolicy.Expanding,QSizePolicy.Expanding)

layout.addWidget(self.headLabel,0,0,1,2)

policy = self.headLabel.sizePolicy()

print(policy.verticalPolicy())

policy.setVerticalPolicy(1)
