PySide6 之登录界面设计

一、效果图

二、示例代码

from PySide6.QtWidgets import QApplication, QWidget
from PySide6.QtCore import Qt, Slot, QPoint, QPropertyAnimation, QEasingCurve
from  PySide6.QtGui import QColor

from views.login_ui import Ui_LoginForm
import sys

class Login(QWidget, Ui_LoginForm):
    drag_pos = QPoint()
    animation = None

    def __init__(self):
        super().__init__()

        self.setWindowFlags(Qt.WindowType.FramelessWindowHint)
        self.setAttribute(Qt.WidgetAttribute.WA_TranslucentBackground)
        self.setupUi(self)


    @Slot()
    def on_pushButton_close_clicked(self):
        self.close()

    def paintEvent(self, event):
        if not self.animation:
            self.animation = QPropertyAnimation(self)
            self.animation.setTargetObject(self)
            self.animation.setPropertyName(b"windowOpacity")
            # 设置初动画始值
            self.animation.setStartValue(0)
            # 设置动画结束值
            self.animation.setEndValue(1)
            # 设置动画线性
            self.animation.setEasingCurve(QEasingCurve.Linear)
            # 设置动画时长
            self.animation.setDuration(500)
            # 设置循环次数 如果是-1则无限循环
            self.animation.setLoopCount(1)
            self.animation.start()
            event.accept()

    def mousePressEvent(self, event):
        if event.buttons() == Qt.MouseButton.LeftButton:
            self.drag_pos = event.globalPos() - self.frameGeometry().topLeft()
            event.accept()
    
    def mouseMoveEvent(self, event):
        if event.buttons() == Qt.MouseButton.LeftButton:
            self.move(event.globalPos() - self.drag_pos)
            event.accept()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    d = Login()
    d.show()
    sys.exit(app.exec())
