cargo run --example checkbox

Interactive Mode (Default)

Navigate and toggle checkboxes with your keyboard:

↑/↓ or k/j - Navigate between checkboxes
Space - Toggle checkbox state
Tab - Switch to API Showcase mode
q or Esc - Quit

The interactive mode demonstrates:

Basic checkbox with default styling
Styled checkboxes with colors (Info, Warning, Error)
Emoji and Unicode symbols (✅, ●, ◆)
Custom ASCII symbols ([X], [*], [+]/[-], (X)/(O))

API Showcase Mode

Press Tab to switch to the API showcase view, which displays all available features:

All core API methods (new(), default(), label(), checked())
All styling methods (style(), checkbox_style(), label_style())
Symbol customization (checked_symbol(), unchecked_symbol())
All predefined symbols from the symbols module
Advanced usage (blocks, Styled trait, method chaining)

Styling

The widget supports multiple styling options:

style(): Sets the base style for the entire widget
checkbox_style(): Sets the style specifically for the checkbox symbol
label_style(): Sets the style specifically for the label text

Styles are applied in order: base style, then specific styles override it.

Custom Symbols

The widget comes with default Unicode checkbox symbols (☐ and ☑), but you can use any symbols:

// Emoji style
Checkbox::new("Task", true)
    .checked_symbol("✅ ")
    .unchecked_symbol("⬜ ");

// ASCII style
Checkbox::new("Task", false)
    .checked_symbol("[X]")
    .unchecked_symbol("[ ]");

// Circle style
Checkbox::new("Task", true)
    .checked_symbol("● ")
    .unchecked_symbol("○ ");

Predefined Symbols

The symbols module provides some common checkbox symbols:

symbols::CHECKED - ☑
symbols::UNCHECKED - ☐
symbols::CHECKED_X - [X]
symbols::UNCHECKED_SPACE - [ ]
symbols::CHECKED_ASTERISK - [*]
symbols::CHECKED_PLUS - [+]
