//! Example: File Explorer
|
|
//! -------------------------
|
|
//!
|
|
//! This is a fun little desktop application that lets you explore the file system.
|
|
//!
|
|
//! This example is interesting because it's mixing filesystem operations and GUI, which is typically hard for UI to do.
|
|
//!
|
|
//! It also uses `use_ref` to maintain a model, rather than `use_state`. That way,
|
|
//! we dont need to clutter our code with `read` commands.
