Struct UIPage 

pub struct UIPage { /* private fields */ }

UI 页面结构 (支持多页面转场)

每个 UIPage 包含:

• 一个 widget 树 (root_widget)
• 一个内置 Buffer (用于渲染和转场)
• 事件分发器和主题管理器

使用方式

// 创建多个页面
let mut page_a = UIPage::new(80, 30);
page_a.set_root_widget(Box::new(slide1_panel));

let mut page_b = UIPage::new(80, 30);
page_b.set_root_widget(Box::new(slide2_panel));

// 渲染到各自的 buffer
page_a.render();
page_b.render();

// 使用转场混合
let transition = WipeTransition::left();
transition.transition(
    page_a.buffer(),
    page_b.buffer(),
    tui_buffer,
    0.5  // 50% 进度
);

Implementations

impl UIPage

pub fn new(width: u16, height: u16) -> Self

pub fn set_root_widget(&mut self, widget: Box<dyn Widget>)

pub fn set_theme(&mut self, theme_name: &str) -> UIResult<()>

pub fn set_frame_rate(&mut self, fps: u32)

pub fn handle_input_event(&mut self, input_event: InputEvent)

pub fn update(&mut self, dt: f32) -> UIResult<()>

pub fn render(&mut self) -> UIResult<()>

pub fn render_into(&mut self, target_buffer: &mut Buffer) -> UIResult<()>

Render UI directly into the provided buffer (zero-copy) This is the recommended way to integrate UI rendering with the main game loop

pub fn layout(&mut self)

pub fn resize(&mut self, width: u16, height: u16)

pub fn quit(&mut self)

pub fn is_running(&self) -> bool

pub fn start(&mut self)

pub fn should_render(&self) -> bool

pub fn frame_complete(&mut self)

pub fn buffer(&self) -> &Buffer

Get immutable reference to internal buffer

pub fn buffer_mut(&mut self) -> &mut Buffer

Get mutable reference to internal buffer (for BufferTransition output)

pub fn event_dispatcher(&mut self) -> &mut EventDispatcher

pub fn theme_manager(&self) -> &ThemeManager

pub fn theme_manager_mut(&mut self) -> &mut ThemeManager

pub fn run_simple(&mut self) -> UIResult<()>

Simple main loop for testing (in a real app, you’d integrate with rust_pixel’s main loop)
