A pure QML multi-skin component engine (Fluent + Neobrutalism) with 120fps+ smooth animations
Project description
PrismQML(棱镜映界)
简体中文 | English
一套 QML 控件,多种设计语言一键切换。 PrismQML(棱镜映界)是基于 PySide6 + QML 的多皮肤 UI 引擎:同一套控件,运行时在 Fluent 与 新粗野(Neobrutalism) 之间自由切换,120fps+ 流畅动画。
- 安装:
pip install prismqml - 适合:想用 Python + QML 做现代桌面应用,同时需要统一控件、主题 token、运行时换肤和跨平台窗口能力的项目。
from prismqml import setSkin, Skin
setSkin(Skin.NEOBRUTALISM) # 一行切换整个应用的设计语言
✨ 特性
- 🎨 多皮肤引擎:同一套控件,
setSkin()一键切换 Fluent / 新粗野,支持 light/dark - 🧩 token 驱动架构:颜色、几何、阴影全走 token —— 新增皮肤几乎零控件改动
- ⚡ 纯 QML 渲染:无帧率限制,120fps+ 流畅动画
- 🐍 PySide6 原生:无缝集成,Python 侧管理业务逻辑,不碰 C++
- 📦 控件齐全:按钮 / 输入 / 卡片 / 对话框 / 表格 / 图表 / 导航等全套
- 💾 配置系统:JSON 持久化 + 原子写入 + QML Property 桥接
- 🔄 响应式状态:细粒度 Store 状态管理,支持 watch / batch 模式
- 🪟 窗口管理:多种窗口布局 + 懒加载 + 云母效果 + 系统托盘
- 🌍 跨平台:Windows、macOS、Linux
📦 安装
pip install prismqml
分发名与导入名一致:
pip install prismqml后from prismqml import ...。 运行环境要求 Python 3.9+ 与 PySide6 6.9+(Qt 6.9+)。
开发模式安装:
git clone https://github.com/aki-riko/PrismQML.git
cd PrismQML
pip install -e ".[dev]"
🚀 快速开始
from prismqml import App, Window, WindowType
app = App()
window = app.create_window(WindowType.BAR)
window.setWindowTitle("我的应用")
window.resize(1200, 800)
# 添加导航页面
window.addPage(HomePage, "Home", "首页")
window.addPage(SettingsPage, "Settings", "设置")
window.show()
app.exec()

📐 窗口类型
| 类型 | 枚举值 | 说明 |
|---|---|---|
WindowType.BAR |
1 | 紧凑侧边导航(默认) |
WindowType.SPLIT |
0 | 展开式侧边导航 |
WindowType.FILLED |
2 | 填充式分割窗口 |
from prismqml import App, Window, WindowType
app = App()
# 紧凑侧边导航(默认)
window = app.create_window(WindowType.BAR)
# 展开式侧边导航
window = app.create_window(WindowType.SPLIT)
🎨 皮肤系统(核心)
棱镜映界的招牌能力:皮肤与明暗正交。skin 控制设计语言,theme 控制明暗,两者独立组合。
from prismqml import setSkin, Skin
setSkin(Skin.FLUENT) # Fluent Design:圆角、模糊阴影、蓝主色
setSkin(Skin.NEOBRUTALISM) # 新粗野:粗黑边、硬阴影、橙撞色
QML 侧通过 Enums.skin / Enums.isNeobrutalism 读取当前皮肤:
import PrismQML
Rectangle {
radius: Enums.isNeobrutalism ? 0 : Enums.radius.small
// 但大多数情况你无需判断——控件已自动适配皮肤
}
架构亮点:皮肤差异收敛在 token 层(颜色 / 几何 / 阴影),控件本身对皮肤无感知。 新增第三套皮肤只需扩展 token,几乎不动控件代码。
🌗 主题系统
切换主题
from prismqml import setTheme, Theme
setTheme(Theme.LIGHT) # 浅色
setTheme(Theme.DARK) # 深色
setTheme(Theme.AUTO) # 跟随系统
自定义主题色
from prismqml import setAccentColor, getAccentColor
setAccentColor("#0078d4")
print(getAccentColor()) # "#0078d4"
QML 中使用
import PrismQML as Fluent
// Primary 按钮(style_primary 自动使用全局主题色)
Fluent.Button {
text: "确定"
style: Fluent.Enums.button.style_primary
}
// 访问 ThemeManager 属性
Rectangle {
color: ThemeManager.accentColor
}
说明:
ComboBox、Slider因与 QtQuick.Controls 原生类型同名,未在顶层PrismQML模块导出, 需按子模块目录导入后使用,例如import "../prismqml/PrismQML/controls/inputs"。
⚙️ 配置系统
配置系统采用五层架构:Validator → SettingEntry → SettingsCore → AppConfig → ConfigManager
- JSON 持久化:默认存储于
~/.prismqml/app.json - 原子写入:先写临时文件再替换,防止断电数据丢失
- QML 桥接:通过
ConfigManager单例暴露为 QML Property
from prismqml.python.config import AppConfig, getConfigManager
# 获取配置值
config = getConfigManager()
print(config.lazyLoading) # True
print(config.dpiScale) # 0(跟随系统)
# 修改配置(自动保存到 JSON)
config.setDpiScale(150)
自定义配置项
from typing import ClassVar
from prismqml.python.config import (
SettingsCore, SettingEntry, EnumEntry,
Validator,
)
class MyAppConfig(SettingsCore):
auto_save: ClassVar[SettingEntry] = SettingEntry(
group="Editor", name="AutoSave",
default=True, validator=Validator.boolean(),
)
font_size: ClassVar[EnumEntry] = EnumEntry(
group="Editor", name="FontSize",
default=14,
validator=Validator.choice([12, 14, 16, 18, 20, 24]),
)
📊 状态管理
Store 提供响应式状态存储,支持细粒度 watch 和批量更新:
from prismqml import Store
class AppStore(Store):
def __init__(self):
super().__init__("app")
self.define("user", None)
self.define("count", 0)
store = AppStore()
# 监听变化
store.watch("count", lambda new, old: print(f"{old} → {new}"))
# 设置值
store.set("count", 1) # 输出: 0 → 1
# 批量更新(合并通知)
with store.batch():
store.set("count", 10)
store.set("user", "Alice")
# 退出 with 时统一通知
# 字典语法
store["count"] = 20
print(store["count"]) # 20
🔔 系统托盘
from prismqml import SystemTrayIcon, Icon
tray = SystemTrayIcon(icon="AppIcon.png", toolTip="我的应用")
tray.addAction(text="显示", icon="Visibility", triggered=window.show)
tray.addSeparator()
tray.addAction(text="退出", icon="Power", triggered=app.quit)
tray.show()
🧩 UI 组件
控件
Button · Card · CheckBox · ToggleSwitch · LineEdit · ComboBox · Slider · ProgressBar · SpinBox · TableView · ListView · TreeView
导航
NavigationBar · NavigationView · Pivot · Breadcrumb · Windows
特效
Shadow · ShadowedRectangle · ColorOverlay · GaussianBlur
完整组件清单见各
controls/子目录的qmldir。ComboBox、Slider等与 QtQuick 原生同名的组件需经子模块目录导入。
🧪 测试
python scripts/test_process.py --qt-platform offscreen --timeout 300 -- python -m pytest tests/ -v
python scripts/test_process.py --qt-platform offscreen --timeout 180 -- python -X utf8 tests/qml/probe_all_components.py
自动化 pytest 与 QML probe 始终强制使用 offscreen,调用者已有的 windows / minimal 等平台值也会被覆盖。Windows 下 test_process.py 会把完整测试进程树放入私有 Desktop 与关闭即终止的 Job Object,因此测试 UI(包括短暂窗口)不会出现在当前用户桌面;runner 会轮询检测 Job 内持续可见窗口,检测到时记录证据并以 126 失败,正常退出或超时时确认全部后代进程归零。请勿绕过该 runner 裸跑自动化测试。单独运行标注为手工窗口测试的脚本仍可能显示 UI。C++/CTest 的真实 Windows Mica 验证说明见 cpp/README.md。
