PyQt信号槽实现页面的登录与跳转 #页面进一步优化

知识鱼丸2024-12-10 8:41

将登录框中的取消按钮使用信号和槽的机制，关闭界面。

将登录按钮使用信号和槽连接到自定义的槽函数中，在槽函数中判断ui界面上输入的账号是否为"admin"，密码是否为"123456",如果账号密码匹配成功，当前界面关闭，另一个界面展开。如果匹配失败，则输出登录失败，并将密码框和账号框中的内容清空

pyside转换前

Pyside将ui转换为py文件，将项目资源导入后

代码如下：（主执行代码）

python 复制代码 
import sys
from PySide6.QtCore import Qt
from PySide6.QtWidgets import QWidget,QApplication

from login_sea import Ui_Form
from login_succes import Ui_Form2


#界面1（按钮）
class MyWidget(Ui_Form,QWidget):
    def __init__(self):
        super().__init__()
        self.setupUi(self)
        self.pushButton.clicked.connect(btn_def)


#界面2
class SecMyWidget(Ui_Form2,QWidget):
    def __init__(self):
        super().__init__()
        self.setupUi(self)



def btn_def():
    name = myWidget.lineEdit_1.text()
    password = myWidget.lineEdit_2.text()
    if name=='admin'and password=='123456':
        myWidget.close()
        second.show()
    else:
        print('输入错误')

if __name__ =='__main__':
    app = QApplication(sys.argv)

    myWidget=MyWidget()

    myWidget.setWindowFlag(Qt.WindowType.FramelessWindowHint)
    myWidget.setAttribute(Qt.WidgetAttribute.WA_TranslucentBackground)

    myWidget.show()

    second=SecMyWidget()
    second.setWindowFlag(Qt.WindowType.FramelessWindowHint)
    second.setAttribute(Qt.WidgetAttribute.WA_TranslucentBackground)
    #阻塞
    sys.exit(app.exec())

剩下两个页面的ui转py代码：
