CInput

Requires PythonExtra runtime to execute.

CInput is a standalone UI library for PythonExtra that adds touchscreen keyboard input, themed dialogs, and list pickers to ClassPad II applications. Build interactive apps with minimal boilerplate.

Features

• Touchscreen keyboard: QWERTY, AZERTY, QWERTZ, and ABC layouts
• Themed UI: light, dark, and grey themes with consistent styling
• Input dialogs: text, integer, and float entry with validation
• List pickers: single and multi-select list interfaces
• Modal system: non-blocking dialogs that integrate with event loops
• Lightweight: single-file dependency, ~10 KB footprint

Quick Start

import cinput

# Text input
name = cinput.input("Enter your name:", type="text", theme="dark")

# List picker
choice = cinput.pick(["Option A", "Option B", "Option C"], "Select one")

# Multi-select
items = cinput.pick(["Item 1", "Item 2", "Item 3"], "Pick many", multi=True)
