Struct ViewContext 

pub struct ViewContext {
    pub size: Size,
    pub theme: Arc<Theme>,
    /* private fields */
}

Environment passed to Component::render: terminal size and theme.

Every render call receives a ViewContext so components can adapt to the available space and use semantic colors from the Theme.

Construction

use tui::ViewContext;

// Default theme
let ctx = ViewContext::new((80, 24));

// Custom theme
use tui::Theme;
let ctx = ViewContext::new_with_theme((120, 40), Theme::default());

Methods

• with_size(size) — Clone the context with a different Size, preserving the theme (and syntax highlighter). Useful when rendering a child into a sub-region.
• highlighter() — Access the SyntaxHighlighter (requires feature syntax).

Size

Size holds terminal dimensions as width (columns) and height (rows), both u16. Implements From<(u16, u16)> for convenient construction.

See also

• Theme — The semantic color palette.
• Renderer — Creates ViewContext automatically from its own state.

Fields

size: Size

theme: Arc<Theme>
