PawUI

轻量、直接运行的 Python 声明式 UI 层。HTML 风格,Qt/PySide6 渲染(原生抗锯齿、QSS 圆角/悬停/聚焦、IME 组字正常),无构建。

安装

pip install pawui        # 依赖 PySide6>=6.5,自动安装
python -m pip install --upgrade pawui

运行

pawui app.paw

也可以传统方式启动:

import pawui
pawui.run("app.paw")

语法(HTML 风格)

<Window title="你好" width="460" height="840" theme="dark">
  <Column padding="24" spacing="12">
    <Text size="24" bold>欢迎使用 PawUI 👋</Text>
    <Text size="13" color="subtext">副标题</Text>

    <Text>{$greeting}</Text>

    <Row spacing="8">
      <Button on_click="increment">点我 +1</Button>
      <Button on_click="reset">清空</Button>
    </Row>

    <Input placeholder="输入你的名字..." on_change="on_name"/>
    <Text>你好,{$name}</Text>

    <Card label="点击量" value="{$count}"/>
  </Column>
</Window>

<!-- 自定义组件 -->
<Component name="Card">
  <Column padding="12" bg="surface">
    <Text color="subtext">{$label}</Text>
    <Text size="22" bold>{$value}</Text>
  </Column>
</Component>

<script>
def increment():
    state.count = int(state.get("count", 0)) + 1
</script>

要点

  • 状态绑定{$count} / {count} / $count,在 <script> 里改 state.count = ... 界面自动刷新。
  • 事件:字符串引用 <script> / main.py 里的函数:on_click="函数名"
  • 组件<Component name="X">...</Component> 定义,直接 <X .../> 使用。
  • 主题theme="dark" | "light",颜色可直接引用:color="subtext"bg="surface"
  • 布局Column 纵排、Row 横排,spacing / padding 调节。

内置组件

Window Column Row Text Button Input Checkbox(开关) Divider Spacer If(条件渲染) For(列表循环)

<For each="item" in="{$items}">
  <If condition="{$item.done}">
    <Text>{$item.name}</Text>
  </If>
</For>
