Pyside6入门教学——编写一个UI界面并显示-Toy模板网

这篇具有很好参考价值的文章主要介绍了Pyside6入门教学——编写一个UI界面并显示。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

1、安装Pyside6

输入下列命令安装Pyside6。
- ```
pip install Pyside6
```

2、设计UI

打开Qt设计工具（在安装Pyside6包的目录下）。
- 【注】我这用的是anaconda虚拟环境，所以我的路径是D:\App\Anaconda3\envs\snake\Lib\site-packages\PySide6。
设计一个界面，如何设计这里不详细讲解。
- 设计完后保存，得到一个ui文件。（另存到项目的目录下，方便查找）

3、转换为py文件

打开终端，进入ui文件所在的路径。输入命令进行转换：
- ```
PySide6-uic SedentaryReminder.ui -o ui_SedentaryReminder.py
```

得到py文件。

        self.label_2.setText(QCoreApplication.translate("MainWindow", u"\u9009\u9879\uff1a", None))
        self.label.setText(QCoreApplication.translate("MainWindow", u"\u8ba1\u65f6\u5668\uff1a", None))

        self.label_6.setText(QCoreApplication.translate("MainWindow", u"\uff08\u5206\u949f\uff09", None))
    # retranslateUi

4、显示界面

使用Pycharm创建一个新的项目，并创建一个python文件。

from PySide6.QtWidgets import QApplication, QMainWindow
from ui_SedentaryReminder import Ui_MainWindow


class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.ui = Ui_MainWindow()  # UI类的实例化
        self.ui.setupUi(self)


if __name__ == '__main__':
    app = QApplication([])  # 启动一个应用
    window = MainWindow()  # 实例化主窗口
    window.show()  # 展示主窗口
    app.exec()  # 避免程序执行到这一行后直接退出
