# main.vp — ViperQtProject：vqt6 扩展功能测试
|

# main.vp — ViperQtProject：VS Installer 风格安装向导演示
|
||||
#
|
||||
# 演示：QMainWindow + 布局 + 信号槽回调 + 多控件 + QTimer 自动退出
|
||||
# 纯界面演示（无真实安装逻辑）：
|
||||
# 步骤0 欢迎 → 步骤1 组件选择 → 步骤2 安装进度（QTimer 模拟）→ 步骤3 完成
|
||||
# 左侧导航高亮当前步骤，右侧 QStackedWidget 切换页面，深色主题 QSS。
|
||||
#
|
||||
# 注意：
|
||||
# - QApplication(argv) 的 argv 被包装层忽略（桥接层提供虚拟 argv），传 t.CPtr(0) 即可
|
||||
# - 回调签名统一: def cb(slot_id: int, data: t.CPtr)，data 默认传 0（null）
|
||||
# - 布局 addWidget 接收控件指针（控件 ._ptr）
|
||||
# - 回调里更新文本用 UTF-8 便捷 FFI（vqt6_qlabel_set_text_utf8 等），
|
||||
# 避免跨模块调用返回 QString 指针时 TPV 无法推断返回类型
|
||||
# 说明：
|
||||
# - 回调签名统一 def Cb(slot_id: int, data: t.CPtr)
|
||||
# - 跨模块 FFI 调用避免返回指针的函数（用 *_utf8 便捷版 + 整数返回函数）
|
||||
# - 模块级全局只存 t.CPtr 指针（不存对象）
