rust-fltk-todolist

---

Rust/fltk-rs desktop demo application that uses the fltk-rs GUI framework and persists data in a database-like binary file, performs a full CRUD, and displays a to-do list in GUI.

🤦 Yes, just another to-do application, but to try something new you have to start somewhere ¯\_(ツ)_/¯.

🤔 Explanation

fltk-rs is a Rust bindings for the FLTK Graphical User Interface library.

The fltk crate is a cross-platform lightweight gui library which can be statically linked to produce small, self-contained and fast gui applications.

Why choose FLTK?

• Lightweight. Small binary, around 1mb after stripping. Small memory footprint.
• Speed. Fast to install, fast to build, fast at startup and fast at runtime.
• Single executable. No DLLs to deploy.
• Supports old architectures.
• FLTK's permissive license which allows static linking for closed-source applications.
• Themeability (5 supported schemes: Base, GTK, Plastic, Gleam and Oxy), and additional theming using fltk-theme.
• Provides around 80 customizable widgets.
• Has inbuilt image support.

Here is a list of software using FLTK. For software using fltk-rs, check here.

• Link to the official documentation.

Fluid

FLTK offers a GUI WYSIWYG rapid application development tool called FLUID which allows creating GUI applications. Currently there is a video tutorial on youtube on using it with Rust: Use FLUID (RAD tool) with Rust (more info here).

Conclusion:

Use this library if you want something very, very light, quick to code and compile... and you like somewhat minimalist interfaces like me.🤓

👨‍🚀 Getting Started

Run the application:

Install the Rust toolchain and run the following command in the root directory of the project:

cargo run

Create an app bundle (.deb file & executable binary for MacOS/Linux):

Run the following command at the root of the project (it is necessary to have installed cargo bundle in the system using cargo install):

cargo bundle --release

Note

On Linux, if you install the application using the .deb file, a .todo.dat file will be generated in the user folder. We can establish the path of said file if we edit the application's preferences from its launcher.

Happy coding 😀!!
