//! # flandres
//! fltk widgets adapted for Android.
//!
//! This crate provides public wrapper functions which return fltk widgets. These widgets are styled and adapted to Android screen resolution.
//!
//! # Usage
//! Add flandres to your fltk applications.
//! ```toml
//! [dependencies]
//! fltk = "0.15"
//! flandres = "0.2"
//! ```
//!
//! ```rust
//!     let mut win = flandres::window();
//!     let _inp = flandres::inout_widget::<fltk::input::Input>(200, 200, 200, 100, "");
//!     let _but: fltk::button::Button = flandres::widget(200, 600, 200, 100, "Click Me!");
//! ```
