一、效果图

二、qtDesigner

原理是利用属性动画来控制QFrame的minimumWidth属性。

①先拖出相应的控件

②布局一下

③填上一些样式

三、ui文件如下：

XML 复制代码

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>Form</class>
 <widget class="QWidget" name="Form">
  <property name="geometry">

四、代码

使用uic工具将ui文件转成py文件

python 复制代码

import sys

from PySide6.QtCore import QPropertyAnimation, QEasingCurve, QParallelAnimationGroup
from PySide6.QtWidgets import *

from zzz.ui_home_03 import Ui_Form


# 继承UI类
class MainWindow(QWidget, Ui_Form):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        self.setupUi(self)
        self.pushButton.clicked.connect(self.settingBox)

    def settingBox(self):
        widthRightBox = self.frame_2.width()
        maxExtend = 100
        standard = 0

        if widthRightBox == 0:
            widthExtended = maxExtend
        else:
            widthExtended = standard

        # 创建属性动画
        self.right_box = QPropertyAnimation(self.frame_2, b"minimumWidth")
        self.right_box.setDuration(500)
        self.right_box.setStartValue(widthRightBox)
        self.right_box.setEndValue(widthExtended)
        self.right_box.setEasingCurve(QEasingCurve.InOutQuart)
        self.right_box.start()

        # 动画组 如果是多个动画同时执行，则创建动画组。
        # self.group = QParallelAnimationGroup()
        # self.group.addAnimation(self.right_box)
        # self.group.start()

if __name__ == '__main__':
    app = QApplication()

    window = MainWindow()
    window.show()

    sys.exit(app.exec())
