# Declare-PySide | 声明式 PySide 界面库
`declare-pyside` 可以让开发者以 "声明式" 的纯 Python 语法编写可视化界面框架. 借助 Qt 强大的图形表达能力和 Python 简洁直观的嵌套式语法结构, 您将以全新的方式创造现代化的用户图形界面.
`declare-pyside` 在以下方面具有显著优势:
**1. 声明式的语法**
下面两张图分别展示了命令式语法 (左图) 和声明式语法 (右图) 的表现方式:

**2. 健全的类型提示系统**

**3. 调用方式的优化**

**4. 热重载**

# 快速开始
`declare-pyside` 的组件基于 QML 组件生成. 如果您之前是 QML 开发者, 那么这个库的上手难度会小很多.

from declare_pyside import *
from declare_pyside.widgets import *
from lk_lambdex import lambdex
""" Description
- Two lines of text are center in window.
- A button is under text lines.
- Click button to update text1's text and font size.
- The text2's text is synchronized to text1's text, but font size stayed.
